The most powerful low pressure system in 140 years of record keeping swept through the Southwest U.S. yesterday, bringing deadly flooding, tornadoes, hail, hurricane force winds, and blizzard conditions. We expect to get powerful winter storms affecting the Southwest U.S. during strong El Niño events, but yesterday's storm was truly epic in its size and intensity. The storm set all-time low pressure records over roughly 10 - 15% of the U.S.--over southern Oregon, and most of California, Nevada, Arizona, and Utah. Old records were broken by a wide margin in many locations, most notably in Los Angeles, where the old record of 29.25" set January 17, 1988, was shattered by .18" (6 mb). Bakersfield broke its record by .30" (10 mb). The record-setting low spawned an extremely intense cold front that rumbled thought the Southwest, and winds ahead of the cold front reached sustained speeds of hurricane force--74 mph--last night at Apache Junction, 40 miles east of Phoenix. Wind gusts as high as 94 mph were recorded in Ajo, Arizona, and a Personal Weather Station in Summerhaven (on top of Mt. Lemmon next to Tucson) recorded sustained winds of 67 mph, gusting to 86 mph, before the power failed. Prescott recorded sustained winds at 52 mph, gusting to 67 as the cold front passed, and high winds plunged visibility to zero in blowing dust on I-10 connecting Phoenix and Tucson. The storm spawned one possible tornado in Arizona, which touched down at 8:32 pm MST in Phoenix near Desert Ridge Mall. No damage or injuries were reported. If verified, it would be only the 7th January tornado in Arizona since record keeping began in 1950.

Three tornadoes in California
Three tornadoes were reported in California yesterday. A small EF0 twister hit the east side of Ventura, leaving a 1.5 mile damage path. Another tornado hit Santa Barbara, downing trees and power poles. The most damaging California tornado yesterday touched down just west of Blythe, on the Arizona-California border, at 4:31 pm MST. The twister crossed I-10, blowing three semi trucks over, ripping the roofs off houses, and downing power lines. I-10 was closed for several hours to clear the debris and toppled trucks.
Two tornadoes also hit Southern California on Tuesday. A sheriff's deputy spotted a possible tornado in Goleta that caused some roof damage, and another tornado hit Huntington Beach, damaging boats and buildings and flipping cars.
If all five tornadoes are confirmed as genuine by the National Weather Service, it will tie the record of most January California tornadoes. The all-time record for most California tornadoes in a single day is seven, set on April 1, 1996, and November 9, 1982.
Figure 2. Radar reflectivity from the Los Angeles Doppler radar at the time of the Santa Barbara tornado.
Figure 3. Storm-relative radial velocity from the Los Angeles Doppler radar at the time of the Santa Barbara tornado. The area of yellow and orange colors, lying right next to a region of blues and greens just west of Santa Barbara shows that the winds in that region were moving towards and away from the radar in a very tight area, signifying the presence of a rotating thunderstorm and possible tornado.
The storm will continue to bring heavy rain and snow to many portions the Southwest today, then wind down on Saturday. A new storm is expected to move ashore over Northern California on Sunday night, but this storm will not be as intense. Another storm is also possible next Friday, January 29, but it appears that a renewed battering by a long succession of storms like we had this week will not occur next week.

Tornadoes, severe weather in the South
Severe weather associated with a separate storm brought damaging winds, hail, and tornadoes to portions of Kentucky, Tennessee, Georgia, Alabama, and Florida last night. Two tornadoes were reported, one in Tennessee, and one in Alabama, near Huntsville. The Huntsville tornado injured approximately six people, and cut power to 10,000 people. The storm responsible for the severe weather has moved out to sea, and no further severe weather is expected today. A slight chance of severe weather is expected Saturday over Arkansas and Mississippi, and there is also a severe weather threat for Georgia and surrounding states on Sunday.
Figure 4. Last night's Huntsville, Alabama tornado was captured by wunderphotographer Southampton.
Portlight's Paul Timmons to appear on NBC and CNN
Portlight.org, the disaster-relief charity that has sprung up from the hard work and dedication of many members of the wunderground.com community, has successfully shipped medical equipment and a water filtration unit capable of supplying the needs of 3,500 people per day to the Dominican Republic. The relief supplies were trucked to Haiti via road, and have made it to the earthquake zone. The supplies have been targeted to go to those with disabilities, or to those who are living in areas where the main aid efforts have been inadequate. Portlight is working through the local Catholic Church, which is probably best positioned to deliver private aid donations to those in need. Paul Timmons, leader of the Portlight relief efforts, is scheduled to appear on NBC news later today, and on CNN news tomorrow, to discuss Portlight's efforts.
Figure 5. Walkers and medical supplies for Haiti getting ready to ship from the Portlight warehouse in Atlanta.
Please visit the Portlight.org blog to learn more. Floodman's blog has the latest info on Portlight's plan for Haitian relief. The Reeve Foundation, founded by Christopher and Dana Reeve has awarded Portlight Strategies a $10,000 Quality of of Life grant to assist in the relief efforts in Haiti. This is very big and will allow Portlight to pursue more aggressive relief efforts over the course of the next few weeks.
For those of you more interested in helping out with the long-term rebuilding of Haiti's shattered infrastructure from the quake, I recommend a contribution to Lambi Fund of Haiti, a charity that is very active in promoting reforestation efforts, use of alternative fuels, and infrastructure improvements at a grass-roots level in Haiti. I've developed a great respect for the work they do in the country in the five years I've been a supporter.

My next post will be Monday.

Southern California Snow (

A Pacific storm (usually warm) came and dropped snow in Southern California in area which rarely see snow. This was not even an "insider slider" (lingo for a northern, non-Pacific cold jet stream). Snow days for schools are rampant and there are many accidents on the roadways. Our snow is not the typical fluff, but very wet and slick.

On another note, congrats to Colts and Saints fans! I'm sure NOLA will be partying into the afternoon xD.
agreed and seconded...
Ahh, the first of the "the referees lost the game for them" comments.
The 4th an 1 call he did not make it as he fumbled the ball and actually lost 1 yard as he should have lost his forward progress.....But it is what it is. Congratulations to all Colts and Saints Fans!
Hey the Vikings beat themselves with all the turnovers and yes one could say the Saints caused the turnovers. But, my guess would be that only SAints fans would say the bad calls by the referees at the end was not bad calls.....LOL
Forcing fumbles and making a quarterback scramble and throw across his body to the middle of the field might have something to do with it. But, my guess would be that only a Vikings fan would dispute calls that were difficult to see at ground level for a referee and not even able to be over turned on review.
ROFLMAO........NO Viking fan here but, was actually glad to see the Saints win. Just hated to see the bad calls made at the end! Hated to see that!
WHO DAT? YEAH, WE GOT A BLACK AND GOLD SUPERBOWL!

Some time during the first-second week of February.
Long range models point to another extended arctic outbreak(but of course those from the northern Plain and the rest of the east and central states will still find Miami as an escape haven).
Thanks I need it
A 'WHO DAT' WARNING MEANS THAT CONDITIONS FOR MASS SPAMAGE, YELLING, OR SCREAMING OF 'WHO DAT'S' WILL SOON OR IS ALREADY OCCURRING.

By ALICIA CHANG, AP Science Writer, Sun Jan 24
LOS ANGELES – Think the recent wild weather that hammered California was bad? Experts are imagining far worse.
As torrential rains pelted wildfire-stripped hillsides and flooded highways, a team of scientists hunkered down at the California Institute of Technology to work on a "Frankenstorm" scenario — a mother lode wintry blast that could potentially sock the Golden State.
The hypothetical but plausible storm would be similar to the 1861-1862 extreme floods that temporarily moved the state capital from Sacramento to San Francisco and forced the then-governor to attend his inauguration by rowboat.
Hi, dear "Jerry"! Was too revved up after game to go to sleep right away. Your link doesn't work because there is a comma after www instead of a period.
I did read the update to your blog, though; and the list of accomplishments regarding Haiti is rather astonishing. Your blog is well-written -- must have been a lot of work on its own.
I'm actually "coming down" or calming down now...yawn... I'll wu-mail you and LST tomorrow about this and that. Have a great night, everyone!
Thank you, dear...the update was a coolaborative effort between Press and I; we tend to work well together...
Well, I'm going to take my wife off to bed; it's been along day and Morpheus beckons...
nope sry waterwitch11.. what do u like to b called by ?
