Of course I washed my car this weekend after not doing so for 3 weeks, and now it rains.

Severe risk update for today. For Oklahoma - Slight Risk of Severe Weather for Central and Eastern OK. This includes areas east of a line from Wichita Falls to Lawton to Yukon to Guthrie to Stillwater to just east of Newkirk. Main risk is large hail and damaging winds. There is a tornado threat mainly along and east of I-44. Timing still looks good but may be an hour or two slower than originally mentioned.

Outside of Oklahoma a severe weather outbreak is expect over much of Arkansas into Southern Missouri, extreme W TN, NW MS, Northern LA, and extreme NE TX. Very large hail, destructive winds, and a few strong tornadoes are expected.

SPC outlook for Oklahoma...


...SRN PLAINS/ARKLATEX/LOWER TO MID MS VALLEY... AN UPPER-LEVEL TROUGH OVER THE ROCKIES WILL MOVE EWD INTO THE GREAT
PLAINS TODAY AS A POWERFUL 90 TO 110 KT MID-LEVEL JET OVERSPREADS
THE SRN AND CNTRL PLAINS. AS THE EXIT REGION OF THE MID-LEVEL JET
CORE MOVES ACROSS THE SRN PLAINS THIS MORNING...THUNDERSTORMS APPEAR
LIKELY TO DEVELOP FROM SE KS SWWD ACROSS CNTRL OK INTO NORTH TX.
THIS ACTIVITY SHOULD DEVELOP A SEVERE THREAT AROUND DAYBREAK AS A
BAND OF LARGE-SCALE ASCENT MOVES INTO THE SRN PLAINS AHEAD OF THE
APPROACHING UPPER-LEVEL SYSTEM. CONVECTIVE COVERAGE SHOULD QUICKLY
INCREASE THIS MORNING WITH A SQUALL-LINE DEVELOPING AND MOVING EWD
ACROSS THE OZARKS AND ARKLATEX REGION THIS AFTERNOON. CONDITIONS
WILL BE FAVORABLE FOR SEVERE STORMS ACROSS A LARGE AREA AND A
SIGNIFICANT SEVERE WEATHER EVENT APPEARS LIKELY TO OCCUR LATE THIS
AFTERNOON FROM SERN MO SWWD ACROSS AR INTO NRN LA.

The water conservation people should be bowing. A few car washes to bring rain. It's a nice tradeoff.

I love how mud can fall from the sky in Oklahoma....

Radar estimates of rainfall - any hail will throw these off, so these are going to appear too high in some places.

I'm glad this January thread is nearly complete. Keeping my fingers crossed for more interesting days in February.

Does anyone else want to shake the news, and especially weather, people, when they mention how very rare severe storms and tornadoes are in the winter? I mean, they happen every year. True, it's outside "season" but that doesn't make it rare. We know there are three tornado seasons, don't we?

This is the misconception with all "major" weather events.

All of these 'rare and extreme' occurances happen throughout the year...every year.


Mainstream media and general public are simply dramatic and unaware of how averages work.

Might is the keyword. Most model runs have been keeping anything substantial east of I-35.
