The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Shreveport, LA (KSHV), launched 00:00Z, 0.9 hours before the alert went out and 226 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Jan 30, 5:55 PM CST, 1 hour 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
555 PM CST SUN JAN 30 2011

.AVIATION...
EXPECT ALL SHRA/TSRA UP NORTH TO WEAKEN AND DISSIPATE THIS EVENING WITH
THE LOSS OF HEATING AND THE EASTWARD MOVEMENT OF THE ASSOCIATED DISTURBANCE.
ALL MODELS BRING IFR/LIFR CEILINGS AND VISIBILITIES TO THE AREA OVERNIGHT.
DID NOT GO AS LOW AS THESE PREDICTIONS AND STUCK WITH IFR LEVELS INLAND
AND LIFR AT THE COAST. IMPROVEMENT SHOULD BE SLOW TOMORROW MORNING...AND
MOST OF THE AREA IS EXPECTED TO REMAIN MVFR FOR MUCH OF THE LATE MORNING
AND AFTERNOON HOURS TOMORROW.

LOOKING AHEAD...DO NOT THINK CONDITIONS WILL BE AS BAD MONDAY NIGHT/TUESDAY
MORNING BECAUSE WINDS SHOULD STAY UP. EXCEPTION COULD BE POSSIBLE SEA
FOG AND ITS MOVEMENT INLAND TO SOME OF THE TAF SITES. STRONG COLD FRONT
WITH GUSTY NW WINDS WILL MOVE THROUGH THE AREA TUESDAY MORNING...ROUGHLY
(PLUS OR MINUS A COUPLE HOURS) AROUND THE CLL AREA SHORTLY AFTER SUNRISE...
IAH AROUND NOON...AND OFF THE COAST AN HOUR OR TWO LATER. 42

.PREV DISCUSSION... /ISSUED 326 PM CST SUN JAN 30 2011/

DISCUSSION...

..COLDEST AIRMASS SO FAR THIS SEASON ON THE WAY...

SHORTWAVE IS CURRENTLY RIGHT OVERHEAD. AREAS JUST NORTH AND WEST
OF THE FEATURE HAVE SEEN CLOUDS CLEAR OUT AND TEMPS CLIMB INTO THE
MID 70S. WITH RESIDUAL MOISTURE IN PLACE ALONG WITH HEATING AND
STEEP LAPSE RATES ALOFT SOME SCT TSTMS HAVE DEVELOPED. THESE WILL
PROBABLY CONTINUE FOR THE NEXT FEW HOURS AND HAVE THE POTENTIAL
TO PRODUCE SOME HAIL. PRECIP SHOULD WANE WITH THE LOSS OF HEATING
AND AS THE S/W MOVES OFF TO THE EAST. AS WINDS DROP OFF LATER THIS
EVENING EXPECT AREAS OF FOG TO DEVELOP. SEA FOG IS ALSO A PRETTY
GOOD BET BUT COULD BE DELAYED BY THE PRECIP COMPLEX CURRENTLY
JUST OFF THE COAST.

WARM AND MOIST CONDITIONS SHOULD PERSIST ON MONDAY BUT WITH LACK
OF A TRIGGER NOT EXPECTING MUCH IN THE WAY OF PRECIP OTHER SOME
SPOTTY SHRA HERE AND THERE. LLJ REALLY CRANKS UP (40-50KT) MON
EVENING AHEAD OF AN ARCTIC FRONT THAT WILL BE MOVING TOWARD THE
REGION. CONSIDERING THE STRONG MOISTURE TRANSPORT (PW'S FCST
1.3" TO 1.5" - BUT PROBABLY SLIGHTLY OVERDONE) EXPECT A FAST SHOT
OF SHRA/TSTMS AHEAD OF THE FRONT AS IT MOVES IN. THE FRONT SHOULD
BE APPROACHING NW PARTS SHORTLY AFTER SUNRISE TUE...HWY 59 CORRIDOR BY
LUNCH...AND OFF THE GLS COAST AN HOUR OR TWO LATER. MORNING TEMPS
IN THE 60S WILL FALL THRU THE DAY AND INTO THE 30S & 40S BY 6PM.

MODELS ARE IN GOOD AGREEMENT SHOWING VERY COLD AIR WITH THIS
SYSTEM...WITH 925 MB TEMPS BOTTOMING OUT BETWEEN -5C (SOUTH) TO -12C
NORTH BY SUNRISE WED. WIND CHILLS IN THE SINGLE DIGITS AND TEENS
ARE POSSIBLE TUE/WED NIGHT. TIME SECTIONS INDICATE 925 NM TEMPS WON'T
MAKE IT ABOVE 0C UNTIL SAT MORNING. THAT BEING SAID...CONTINUED
THE TREND OF LOWERING TEMPS. ALSO WATCHING AN INTERESTING PATTERN
DEVELOP TOWARD THE END OF THE WEEK. A LARGE TROF DEVELOPS ACROSS
THE CNTL US THIS WEEK WITH A FEW SHORTWAVES ROTATING AROUND -
MOSTLY INSIGNIFICANT WX-WISE FOR US AS THEY ARE TOO FAR NORTH.
BUT BY FRI ONE OF THE SHORTWAVES DIGS DEEP INTO NCNTL MEXICO AND
EJECTS INTO SCNTL TX FRI/FRI NIGHT. AS THIS IS OCCURRING ISENTROPIC
LIFT WILL BE ONGOING OVER THE COLD AIRMASS AT THE SFC. PLENTY OF
TIME TO ANALYZE THIS CONSIDERING IT'S SO FAR OUT...BUT WILL GO
AHEAD AND MENTION 20% CHANCE OF -SN ACROSS NRN PARTS FRI
AFTN/NIGHT CONSIDERING FAIRLY GOOD MODEL AGREEMENT. 47

MARINE...
THUNDERSTORMS WERE MOVING ACROSS THE NEARSHORE WATERS AT 230 PM AND
EXPECT THESE TO BE BEYOND 60 NM BY 6 AM. THE ONSHORE WINDS SHOULD
THEN INCREASE TO NEAR ADVISORY CRITERIA LATE MONDAY AND EARLY
TUESDAY. THE COLD FRONT IS STILL EXPECTED TO MOVE OFF THE COAST
TUESDAY AFTERNOON. OFFSHORE WINDS MAY WELL RANGE FROM 25 TO 35 KNOTS
TUESDAY NIGHT...AND SMALL CRAFT ADVISORY CONDITIONS MAY PERSIST INTO
WEDNESDAY EVENING.

THE OTHER MAIN ITEM OF CONCERN WILL BE SEA FOG. PATCHY FOG IS MORE
LIKELY TONIGHT...ALTHOUGH IF THE DEWPOINTS WORK THEIR WAY INTO THE
MID 60S THE FOG WILL BECOME MORE WIDESPREAD. THESE CONDITIONS ARE
MORE LIKELY MONDAY NIGHT AND TUESDAY MORNING AS MOISTURE POOLS AHEAD
OF THE COLD FRONT.
