It's true

I've severely neglected blogging about the weather. Who can blame me? Between twitter and Facebook my Internet time is zapped. Plus those mediums let me say what I want quickly and efficiently.

Well, my wife got me an iPad. So hopefully it will be easier to blog when I have the time. I added a pic below to see how awesome the RadarScope app looks on the iPad. I'm happy with it so far. I'm still working on getting all my weather short-cuts on it.

10 Yr. Record Rain's




An active polar jetstream will transport a series of disturbances over the region this weekend into next week. The shortwaves will combine with the moist airmass and orographic lifting to produce periods of heavier precipitation especially in the mountains and foothills, with higher amounts in San Bernardino county. The graphic displays forecast storm total rainfall for Friday through Tuesday evening.




.. Strong Pacific storm systems will bring high rain amounts to
Southern California through at least Wednesday...

Deep moist flow out of the Pacific will bring periods of rain
through next Wednesday. Heaviest precipitation will occur
Sunday... Tuesday and Wednesday... but steady long-lasting rain of
light to moderate intensity will be likely during other times.
This weekend... southwestern California will be at the south edge
of the deep moisture... so Orange and San Bernardino counties will
generally receive more rainfall than San Diego and Riverside
counties. Strong upslope flow will result in the mountains
receiving large amounts of precipitation... with up to 8 inches
possible in the San Bernardino County mountains through Sunday
night. The moisture plume will be directly over Southern
California Tuesday and Wednesday... so the entire region will
likely have heavy rainfall then.



Total rainfall estimates for the period Friday night through
Sunday night are as follows:

San Diego County coast 1.00 to 1.50 inches
San Diego County valleys 1.50 to 2.00 inches
Orange County coast 1.50 to 2.50 inches
inland Empire 1.25 to 3.00 inches (highest north)
San Diego County mountains 2.00 to 5.00 inches
Riverside County mountains 2.50 to 5.00 inches
Santa Ana Mountains 3.00 to 6.00 inches
San Bernardino County mtns 4.00 to 8.00 inches



Note that mountain totals will be highly variable. For the deserts...

San Diego County deserts around one-half inch
Coachella Valley less than one inch Apple and Lucerne valleys around one inch

Heavy rainfall accumulations are expected... but they will be due to
long durations and not due to heavy intensities. Therefore... the
flash flood threat will be fairly low over the weekend... though this
could change with the heavy rain next Tuesday or Wednesday. Some low
lying spots... especially along streets... could have minor flooding
this weekend. Streams and washes which might normally be dry could
have water flowing through them.



Through Tuesday... snow levels will be above 8000 feet... and
confined to the highest peaks of San Bernardino and Riverside
counties. However... a brief period heavy snow down to 6500 feet
is possible Tuesday night into Wednesday as a cold front comes
through.

I'm excited

OK I've totally slacked as I know that nobody reads this but let me say this, not much has happened weatherwise.

It is however the first day of a forecasted heatwave this weekend. I'll try and post more later.





Above is a pic I took in the shade as I typed this out. ;)

Where's the storm?

San Diego's morning AFD... not looking very promising for a wild weekend. Lower precip as storm passes by well off-shore. Los Angeles even removed TStorms on their land forecast.




"The main rain will be in San Diego County with less in the northern counties.

Quantitative precipitation forecast forecast shows very little for the northern counties with about one to two tenths possible there. San Diego County could still get about one half inch in the lower elevations to one inch in the mountains.

Snow level around 5000 feet mainly late tonight through Sunday morning but could be higher.

Thunderstorms and waterspouts or funnel clouds are possible mainly late tonight through Sunday morning. Moisture wrapping around the low could bring showers to the area until it moves out by late Sunday night or early morning morning. "

Quick Storm





A fast weak trough moved through last night dropping 0.15" of light precipitation. The rain started about 11 PM and lasted until just about 1 AM.

Earthquake, Tsunami, Waterspout, Lightning & Thunder

Yes, it all happened today. We woke to the news of the Chilean 8.8 magnitude quake that devastated Chile overnight. Then we spent the morning waiting for the Tsunami to hit Hawaii. It turned out to be much smaller than forecasted, but it did occur.



In Orange County a small Tsunami did actually appear...


Later on at 3:24PM my buddy Will was streaming live video and captured a waterspout off the coast of Newport Beach.


In the late afternoon as that same line of storms passed, a thunderstorm cell moved right over my house and we got hit with a sudden hail shaft. 3/8" size hail fell for almost 5 minutes while lightning struck and thunder boomed.


Finally the rain and hail stopped as the line moved east. The sky above surprised me with mammatus just before sunset.

Fracto Cumulus Day





Today started out clear enough after the brief showers over night dropped 0.05". About mid morning the heating kicked in and started to produce fracto cumulus. The surface winds were gusty out of the south but a 60kt wind aloft was really mixing things up.



At 11 or so some cumulus congestus formed and the wind really worked hard and tore up the threatening sky and returned it back to scattered fracto quickly.

The rains this winter have been great and the hills are green!

New Frontogenisis

This mornings weather was as expected, overcast marine layer of stratus. Cool but not cold and a bit dry at the surface. The winds are light out of the E to SE. Typical morning weather.








At 11 AM the stratus layer in now burning off a bit. The forecast was for deepening of the layer but that has apparently not happened quick enough to prevent holes in the stratus. Nothing on the radar yet and it seems the consensus is that the low will now close and move south and then east over Baja California. SPC has a slight risk for thunderstorms (mostly offshore) and models show a cooling in the 500mb to -23. The surface winds are still offshore but lightly from the E.




Update: 2:45PM
Over the last few hours the broken marine layer thickened and additional helicity transformed the moisture into cumulus and Cu congestus. The 1km visable shows that most of the clouds are forming onshore. A moderate mid and upper level movement is driving everything east while the surface winds are now trending from the south as the low approaches about 300 miles to the west. SGX AFD is now mentioning that there should be enough LI for small hail in the cells. Currently the front is approaching VBX and a line of showers associated with the front is now visable. The cold core of the low on the IR4 shows storms however they are not as cold in the upper levels as the front is and seem to be weakening.

ChaserCon 2010






As the weather in OC turned fair and summer like, I had the opportunity over this last weekend to attend the National Storm Chaser Convention which is held in Denver, Colorado. The trip took a toll on me though as I was getting or caught a cold. I left on Thursday evening with the entire family on this spontaneous trip at the last minute. We arrived just after noon the next day. I was very tired from the non-stop drive (I only drove a few hundred miles of it) and check-in registration was at 6PM.

The "Con" was opened up early Saturday morning by Co-Owners Roger Hill (Chaser, Press photo/videographer & tornado tour guide) and Tim Samaras (Tornado Researcher and Chaser). The first talk was by Jon Davies called "Where's The Tornado" which discussed the details of a rain wrapped tornado June 7th 2009 in NW Missouri. Next up was a con favorite, Tim Marshall with his talk cleverly titled "The May Trick of 2009" which was certainly a crowd pleaser. I had never seen him speak but let's just say he really get into character. After a short break another well known figure and leader of the largest research project on Tornadogenisis, Dr. Josh Wurman. He discussed in deatil the massive project, Verification of the Origins of Rotation in Tornadoes Experiment 2 (VORTEX2) and his orgainization behind it, the CSWR. This included the highlight of the year for many in research, the Goshen Co, WY tornado of 2009. This tornado was the single most scientifically covered tornadic event in recorded history. The tornado was not only scrutinized by the Vortex team and several other research groups in the area but was televised live on The Weather Channel from start to finish. After lunch Mike Bettes was to speak but couldn't make it due to heavy snow in Atlanta so Tim Samaras filled in the time slot. Mid-Afternoon, Dr. Howie Bluestein from the University of Oklahoma discussed in a detailed overview all of the mobile Doppler's used in the VORTEX2 project. The last speaker of the day was Dr. Erik Rasmussen of Rasmussen Systems who also led the first VORTEX project in the 90's. His topic was "What's left to learn about Tornados?". A vendor fair followed, were I dropped a serious amount of cash on books, DVD's and stickers.

After a quick trip to freshen up at the hotel, I returned for the banquet dinner. I believe it was Mango Chicken and rice with black beans and some steamed veggies. I was surprised to meet a few storm chasers also from California. After dinner was the keynote address by Dr. Greg Forbes (Storm Master G) The Weather Channel's resident storm expert with perspectives on the decade, a look back at the last ten years significant weather events. Dr. Forbes finished with some heartfelt memories of working with the late Ted Fujita. Following the keynote was Chaser Video Night with some very interesting amateur chase videos.

Sunday morning it was snowing pretty good. The ChaserCon started back up with the most important presentation by Chris Novy (WA9V) on "Safe and Responsible Chasing". After, Jon Davies spoke again on chase targeting issues. Next was Greg Stumpf with NSSL & CIMMS at NWS/MDL on the topic "The Evolution of Hazardous Warning Services". At this point I was exhausted from the drive and the massive amount of information I was listening too. I only caught part of the final talk by Dr. Forbes entitled "Severe Weather and Flash-flood forecasting. His talk concluded at noon and by midnight I was 750 miles away in Las Vegas looking for a pillow to lay my sleepy head on.

Below is footage from TWC coverage of the Goshen CO tornado event in June, 2009.

Unstable Tuesday



We had another storm today and it was very cold. Snow was falling above 4,000'. Around 10:30 AM a strong cell moved through the urban area of Orange County creating heavy showers and possible funnel clouds. I personally watch a wall cloud trailing behind the showers and was expecting a funnel cloud to pop out at anytime. In the early afternoon more cells moved through with thundershowers and the steady cold rain continued until just after dusk.

24hrs of rain

I forgot to post about the Friday-Sarurday storm. It dumped over 2" of rain in most places. The front slowed to a crawl overnight Friday and let rain totals unexpectadly add up. Some training and island effect also helped. The rain was low level but pretty wet at times.

More cold unstable weather

A cold upper low will drop swd along ca coast to a position vicinity lax by 12z wed. steep lapse rates and ascent s of e of low track will lead to considerable low topped convection including at least isolated thunderstorms primarily over and west of coastal range
along the track of the upper low as it moves down the coast. given the cold air aloft ... small hail will be likely associated with
stronger convection during the afternoon and evening. the limited instability and generally weak shear ... precludes introducing a
severe threat attm.

did spread the thunderstorm threat ewd across the mohave deserts region of srn ca where models suggest stronger ascent coupled with steep lapse rates will develop during the afternoon.

Slight Chance of Rain




In the past, every chance of rain meant that it would rain somewhere nearby. Now I know the definition of POP chances but still I was always a glass full kind of person. Eventually I came up with my own system to translate POP that seemed to work for several decades. Unfourtunatly it's not very scientific. Basically when the forecast gave a 10% or 20% chance of rain, I would equate that to a dry trough was going to move through or brush by and there would not be rain. When the forecast was 30% chance of rain, we usually got rain. When it was 40%, the average was we would get rain half of the time. 50% chance and above meant we would get rain for sure and it was just a question of how much we would receive. See! Not very scientific.

I've changed my mind. Now my thinking is that anything less than 50% means rain is unlikley. Essentially when I see we have a 20% chance of rain, means to me that we won't get any. This is a fantastic approach because if we ever do which is unlikley then I appreciate the rain just that much more!

Case in point was yesterday. We had a 20% chance at best so to me were weren't getting any and the models were leaning that way after every run as well. We did have a very nice mid-winter time tropical type day. Warm slightly humid air with stratus in the morning giving way to altocumulus and altocirrus towards the afternoon. Not very typical for February in SoCal. Still my hopes were not dashed because the rain never came and I wasn't expecting it either. On a positive note I really enjoy the altocumulus buildups and heaping cumulus. It reminds me of the monsoon season still a half a year away.

DLOC WSR-88D Radar - Initial training


As a supplement to my general knowledge, I've decided to complete the Distance Learning Operations Course (DLOC) which provides initial training on the use of the WSR-88D Radar. Why? Because I'm a weather nut. It is also because understanding this aspect of meteorology will help me not only understand (much) more than the average layman when it comes to the WSR-88D and interpreting it's products, but it will also keep me learning about new subjects in general which is never a bad use of time. The FY09 materials are currently on the web (although hard to find) so I'm taking the initiative to learn as much as I can. Since the next round of training doesn't start until, July, I should have plenty of time to get through it. SInce it's normally a 3-4 week course for NWS forecasters, I think I should be able to get through it in a few months.

GOES-13 is scheduled to replace GOES-12 as the GOES-East operational spacecraft on April 14, 2010


GOES-13 is scheduled to replace GOES-12 as the GOES-East operational spacecraft on April 14, 2010

GOES-13 was launched on May 24, 2006. This spacecraft is the first in the series of GOES-N satellites. GOES-13 carried the same imager and sounder payload as GOES-12, but the new spacecraft bus will allow it to operate through eclipse and
keep out zone periods. The new GOES East images will have increased navigation, registration and radiometric accuracy.

GOES-13 was brought out of storage on 1/27/10 into Pre-Opreational mode. GOES-13 has already began INR & GVAR recovery and will begin imaging and sounding in a GOES-East schedule tomorrow. Starting the 23rd, the Office of Satellite Operations will begin the eastward drift of GOES-13 at approximately 0.5 degrees per day.

GOES-13 will approach 81W on 4/14/10. At this time, GOES-13 GVAR and LRIT will be relayed through the GOES-12 downlink. Ancillary services (DCS/EMWIN/SARSAT) will remain on board GOES-12. GOES-13 will be declared GOES-East in the NOAA GOES Constellation. On 4/26/10, GVAR will be switched from GOES-12 to GOES-13 when GOES-13 is at 75.5W. GOES-13 will stop drift. Ancillary services will switch to GOES-13 at this time. On 4/27/10, GOES-12 will begin eastward drift to 60W in order to replace GOES-10, which was de-orbited in December 2009. Imaging operations for GOES-South America will begin on or about 5/11/10. GOES-12 is expected to arrive on station at 60W on 5/17/10.

Week Review


This last week brought drying, except Tuesday which brought us 0.25". The rain, in my opinion was not a soaking rain but it was average. The temps didn't get too cold like normal winter storms. The latter half of the week was dominated by high pressure and scattered high clouds.

My spare time at night was spent evaluating some software new to me. The first is a free cross-platform program that essentially becomes a scientific GIS viewer for weather & climate data sets. Especially interesting to me was the ability to use live and archived NEXRAD data.

The Integrated Data Viewer (IDV) from Unidata is a Java(TM)-based software framework for analyzing and visualizing geoscience data. The IDV brings together the ability to display and work with satellite imagery, gridded data, surface observations, balloon soundings, NWS WSR-88D Level II and Level III radar data, and NOAA National Profiler Network data, all within a unified interface.

The program can also render movies and images combining data from many different sources. Although it is better for scientific evaluation, it does well at providing a good view of all the NEXRAD products.

The second program I found while obtaining data for the first. It's a simple application that provides basic visualization and data export of weather and climatological data archived at NCDC. It's called "NOAA's Weather and Climate Toolkit" and it seemed to be more appropriate for viewing archived weather data than the IDV.

Needless to say, the high clouds passing through on the 29th blocked my view of the moonrise, the "biggest" of the year but it did provide another spectacular sunset. I was able to see the moon later in the night, big and bright as ever.

Wicked Weather


January 22, 2010
The morning CoCoRaHs rainfall reading was 1.40" bringing the running storm total to 5.97". Another band of rain moved in after midnight and at 4 AM a large band hit hard bringing heavy showers through 6 AM. Two more heavy bands moved in through out the morning. Another larger band moved in for showers from 11 AM till around 2:30 PM. It was at that point the sky grew wicked looking.



A band of convective moisture formed up over the channel islands and as it made land fall in LA county, the intensity became apparent. To the west, the sky grew blackish on the line from Catalina to LA county with rain falling and embedded lightning. At 3:40 PM I spotted what appeared to be a wall cloud (it wasn't I think) hanging from the base of one of the cells just SE of a column of rain. Low scud was also appearing under the front of the line of cells with heavy rain just behind.





Once it reached my location, the was marble sized hail, heavy rain and lightning. After talking with the NWS in San Diego and making a spotter report for the hail and lightning, I stayed on the north side of the canyon in the Yorba Linda area as the band moved through.



By 5:30 PM the rain band had moved east and the sunset hitting some high clouds with colors of warm orange to salmon pink. By 9 PM all the moisture had moved east and the sky was clearing. The week of wild weather appears to be complete.

Lightning!!!


SPC's CPTP Forecast for thunderstorms, 1AM PST Fri.


January 21, 2010
The morning rain gauge reading for the last 24 hours was 1.55", bringing the week storm total to 4.57" of precipitation. It rained much of the day. Rain showers had already started moving in at 2 AM and lasting all morning. At 11 AM, once again, the main rain band moved in from the SSW which lasted until 1:45 PM which exited to the NNE. From 2 PM to 3 PM a quick line of heavy showers moved East across the county. The sky looked very threatening after work. This was my first chance to get out an do some real photography. After the cold front passed in late afternoon a large pool of cold air brought widespread showers and isolated thunderstorms lasting all night.


Afternoon showers over Yorba Linda


Around 7:30 PM a line of storms from Seal Beach to San Dimas brought with it lightning and light grauple. After I took a few stills from home without much luck, I went out to chase. Two storm chaser friends were already out. Storm chaser Gerry a la "OCWX" was up the 15 freeway and chaser Will Wilkens went out as far as San Dimas then doubled back to Ontario Mills.


Night Lightning


My plan was to head up the 57 to San Dimas, but a strong cell that had formed in the line was about to move over Brea so I stopped short of getting on the freeway at Lambert. I was rewarded with very intense rains and some hail with half a dozen lightning strikes both CG and CC. After that cell passed I took off south on the 57 to intercept another strengthening cell moving NE over Seal Beach. Spotting CG to the west, I headed out the 91 W/B as far as Magnolia and turned around as the best dynamics were moving east and the entire line moved east.

From there I headed east as more cells seemed to be heading NE toward Santa Ana. It was at that point that I could either go N 57 to San Dimas or continue east on the 91 to the inland empire and catch what came over the Santa Ana Mountains or head south. I chose south on the 55. Seeing lighting in south county I then took the I-5 further south to Tustin Ranch and got off. At that point the video battery was dead so I switched out the video on the tripod to the still camera. From there it seemed like I had missed the south county storm so I headed back north on the 55 then east 91 to Gypsum. At that point thing died down and it was nearly 11PM. I went home.

A day of rest...sort of

January 20, 2010
The morning rain gauge reading showed a total of 1.17" over the previous 24 hours. After a few brief pre frontal showers the main band began at 11 AM with a short lighter band followed quickly by a deeper band that lasted until the front passed at around 5 PM.



A smaller quick wave of post frontal moisture moved through from about 5:30 PM but all the rain ended after 7 PM. Nothing compared to the day before. Just a lot of rain which would bring the highest 24 hour total of the week.

Tornado!

January 19, 2010
Tuesday mornings rain total from the day before was 1.41" bringing the week storm total 1.85". Although the sky was cloudy most of the morning the next band of rain didn't start until almost 11:45 AM. This would prove to be one of the strongest fronts of the week. Unfortunately my work duties kept me inside for most of the event. Reports from friends kept me in the loop. The rain started as early as 10 AM and covered the county by noon. At 12:45 PM the National Weather service issued the first of four consecutive TORNADO WARNINGS!

I was monitoring the situation o the iPhone getting updates from multiple sources. Storm chaser, Will Wilkens was positioned just two miles from the location and took the time lapse video below.



Once he heard about the tornado on the ground he was on scene in minutes, before authorities arrived. Will who is an Associate Chaser with severestudios.com shot video of a car overturned, tree damage, and roof damage from an EF-0 Tornado that touched down in the Huntington Beach, CA area.



Aside from the tornado, there were damaging winds, lightning an hail which spread across the county. A friend in the canyon told me every intersection along Orangethorpe east of Kraemer was flooded. He also said the storm channel crossing under at Tustin avenue was full and started flowing over the channel siphon/bridge. Needless to say, this was one of the most wild days of the week.

By 2:30 PM, the bulk of the rain had passed and damage assessment began in the calm. Most of the county began to dry the rest of the night.

The first storm

January 18, 2010
Monday lighter sets of light pre-frontal showers were moving in from the west. The first was about 4 AM to 7 AM, then 10 AM to 11:30 AM. The main frontal band moved bringing very heavy rains into Orange County around noon and with frontal passage around 3 PM. Clearing followed the front.




Sunday's rain




January 17, 2010
Rain started falling in Orange County Sunday around 1:45 PM as the first pre-frontal band moved in. By evening, the rain was consistent and covered much of the LA basin. I was supposed to fly to Santa Monica, by the weather was MVFR/IFR so we opted to drive. By 6 AM the next morning we had already received 0.44".
