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.

Area forecast discussion, Mar 31, 11:30 PM CST, 13 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
1130 PM CST THU MAR 31 2005

.NEW DISCUSSION...SEVERE THUNDERSTORM WATCHES #116 AND #117 HAVE
BEEN CANCELLED AND REPLACED WITH TORNNADO WATCH 119 IN EFFECT UNTIL
7 AM. SEVERE THUNDERSTORM WATCH #118 REMAINS IN EFFECT UNTIL 4 AM.
UPDATED ZONES COMING SHORTLY.

MARCOTTE

.PREVIOUS DISCUSSION...NEAR TERM CONCERN IS THUNDERSTORM CHANCES AND
ASSOCIATED SEVERE POTENTIAL TONIGHT.

20Z SFC ANALYSIS PLACED STATIONARY BOUNDARY STRETCHING EAST TO
WEST JUST NORTH OF FORECAST AREA...WITH TROUGH/DRYLINE EXTENDING
NORTH TO SOUTH THROUGH EAST TEXAS. SATELLITE/KLCH 88D RADAR
IMAGERY SHOWING ONE OR MORE EAST WEST ORIENTED MESOSCALE BOUNDARIES
JUST SOUTH OF KLCH.

WHILE THERE HAS BEEN SOME CONVECTIVE ACTIVITY ASSOCIATED WITH
THESE MESOSCALE BOUNDARIES...AGREE WITH SPC THAT MAIN SEVERE
THREAT LIES CLOSER TO STATIONARY BOUNDARY TO THE NORTH AS SFC
CYCLONE DEVELOPS OVER EAST TX AND LIFTS NE TONIGHT. 18Z KLCH
SOUNDING SHOWED A PRONOUNCED TEMPERATURE INVERSION NEAR 825MB
WITH NEARLY DRY ADIABATIC LAPSE RATES ABOVE IT.  RUC FORECAST
SOUNDINGS SHOW THAT INHIBITION HAS ERODED CONSIDERABLY FROM 18Z...
BUT AS OF YET 88D RETURNS WOULD INDICATE THAT WHAT REMAINS IS
IS STILL STRONG ENOUGH.  STILL HAVE ANOTHER COUPLE OF HOURS TO
GET SOMETHING GOING...BUT IF IT DOESNT HAPPEN BY THEN...WELL
HAVE TO WAIT UNTIL LIFT ASSOC WITH UPPER TROF INITIATES STORMS
IN EASTERN TEXAS...WHICH PROPAGATIONAL VECTORS THEN SUGGEST WOULD
MOVE EASTWARD.

COLD FRONT WILL BE EXITING EASTERN PART OF CWA FRIDAY MORNING...
WITH A LINGERING CHANCE OF PRECIP IN THIS AREA.  STOUT NORTHERLY
FLOW AND CAA WILL BE THE RULE...WITH CLOUD COVER FURTHER
INHIBITING MUCH OF A TEMPERATURE INCREASE.  WILL AIM HIGH
TEMPERATURES BELOW NUMERICAL GUIDANCE.

CLOUDS WILL CLEAR TO THE EAST BY FRIDAY EVENING...AND WITH THE
LOSS OF DAYTIME HEATING...TEMPERATURES WILL DROP QUICKLY...BUT
SHOULD NOT COMPLETELY BOTTOM OUT WITH NORTH WINDS EXPECTED TO
NOT COMPLETELY DIMINISH.

TEMPERATURE ADVECTION WILL BECOME NEUTRAL TO WEAKLY WARM ON SATURDAY
WHICH WILL SIGNAL THE RETURN TO MORE SEASONAL TEMPERATURES STARTING
SUNDAY.  FOR SATURDAY NIGHT...INGREDIENTS FOR COOLEST NIGHT OF
FORECAST COME TOGETHER AS SFC HIGH SETTLES IN...WITH RESULTING LIGHT
TO CALM WINDS AND CLEAR SKY COMBINED WITH COOL AND DRY POST FRONTAL
AIRMASS POINTING TO A GOOD RADIATIONAL COOLING EVENT.

FOR DAYS 4 THROUGH 7...EXTENDED RANGE MODELS IN GENERAL AGREEMENT
WITH QUASI-ZONAL FLOW ALOFT PREVAILING THROUGH THE LATTER HALF OF
THE WEEKEND INTO EARLY NEXT WEEK...FOLLOWED BY AN UPPER TROF DIGGING
INTO THE CENTRAL CONUS BY MID WEEK.  CURRENT FORECAST OF CLIMO TEMPS
AND A CHANCE TO SLIGHT CHANCE OF RAIN TUE AND WED STILL LOOKS
GOOD.

&&

.AVIATION...CHANCE OF THUDNERSTORMS TONIGHT AHEAD AND ALONG AN
APPROACHING COLD FRONT THAT WILL MOVE ACROSS THE REGION BETWEEN 06Z
TO 18Z.  VFR CIGS DECREASING TO MVR THIS EVENING AND IFR OVERNIGHT.

&&

.MARINE...SEA FOG WILL LINGER THROUGH TONIGHT UNTIL A COLD
FRONT MOVES THROUGH THE COASTAL WATERS. THE FRONT WILL ENTER
THE WESTERN WATERS SHORTLY AFTER MIDNIGHT TONIGHT...AND EXIT
THE EASTERN WATERS BY MIDDAY FRIDAY. SCATTERED THUNDERSTORMS
ARE POSSIBLE ALONG AND AHEAD OF THE FRONT. EXERCISE CAUTION
STATEMENT OR SMALL CRAFT ADVISORY WILL BE REQUIRED FOR LATE
FRIDAY AS NORTH WINDS STEADILY INCREASE IN THE WAKE OF THE FRONT.
