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

Lake Charles Mun, LA (KLCH), launched 12:00Z, 9.6 hours before the alert went out and 87 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
NATIONAL WEATHER SERVICE LAKE CHARLES LA
232 PM CST TUE NOV 15 2005

.SYNOPSIS...
A STRONG CANADIAN COLD FRONT IS MOVING RAPIDLY SOUTHEAST TROUGH
EAST TEXAS AND NORTHWEST LOUISIANA THIS AFTERNOON. SHOWERS AND
THUNDERSTORMS ARE DEVELOPING ALONG AND AHEAD OF THE FRONT.

THE SPECIAL 18Z UPPER AIR SOUNDING FROM KLCH CONTINUES TO SHOW AN
INCREASE IN MOISTURE AND INSTABILITY ACROSS THE AREA WITH CAPE
VALUES AROUND 3K J/KG AND PWAT NEAR 1.7 INCHES. WINDS HAVE BECOME A
LITTLE MORE UNI-DIRECTIONAL WITH DRY LAYERS STILL SEEN IN THE MID
LEVELS. THEREFORE...LOOKS LIKE SOME DAMAGING WIND GUSTS AND HAIL
WILL BE POSSIBLE WITH SOME OF THE STORMS AS THEY MOVE THROUGH.
HAVE ALREADY HAD WIND GUSTS AROUND 50 MPH IN VERNON PARISH WITH
STORMS THAT WENT THROUGH THERE ABOUT AN HOUR AGO.

A TORNADO WATCH IS IN EFFECT FROM SPC FOR THE LOUISIANA PARISHES
NORTH OF I-10 THROUGH 7 PM.

&&

.DISCUSSION...
COLD FRONT WILL CONTINUE TO MOVE RAPIDLY TO THE SOUTHEAST REACHING
THE LAKES AREA OF SOUTHEAST TEXAS IN A COUPLE OF HOURS AND EXITING
THE FORECAST AREA BY MIDNIGHT.

SHOWERS AND THUNDERSTORMS WILL CONTINUE UNTIL THE FRONT PASSES.

AFTER THE FRONT PASSES...DRIER AND MUCH COOLER AIR WILL MOVE IN.
STRONG NORTH WINDS BEHIND THE FRONT WITH 20 PLUS MPH SUSTAINED
WINDS POSSIBLE ACROSS THE SOUTHERN ZONES AND WILL ISSUE A NPW FOR
A LAKE WIND ADVISORY TO COVER THIS.

COLDEST AIRMASS OF THE SEASON WILL THEN BE THE STORY FOR THE
REMAINDER OF THE WEEK. THURSDAY MORNING LOOKS TO BE THE COLDEST
AT THIS POINT WITH BELOW FREEZING TEMPERATURES POSSIBLE ACROSS THE
NORTHERN ZONES.

A SECONDARY COLD FRONT WILL COME ACROSS THE FORECAST AREA ON
SUNDAY...HOWEVER VERY LIMITED MOISTURE AHEAD OF THIS FRONT AND WILL
LEAVE THE MENTION OF RAIN OUT OF THE FORECAST WITH ITS PASSAGE.

&&

.MARINE...
BREEZY SOUTHERLY WINDS WILL TURN TO THE NORTH THIS EVENING AND
OVERNIGHT AS A COLD FRONT MOVES ACROSS. STRONG COLD AIR ADVECTION
WITH LOW DEWPOINTS RIDING OVER STILL RELATIVELY WARM GULF
TEMPERATURES WILL CAUSE QUITE TURBULENT CONDITIONS. SUSTAINED
WINDS AROUND 30 TO 35 KNOTS WITH FREQUENT GUSTS ABOVE GALE FORCE.
THEREFORE..WILL CONTINUE THE GALE WARNING THAT WAS ISSUED EARLIER.
OFFSHORE WINDS WILL GRADUALLY LESSEN BUT CONTINUE ON THE STRONG
SIDE FOR THE NEXT FEW DAYS.

&&

.AVIATION...
THUNDERSTORMS WILL BE POSSIBLE THROUGH THE EVENING HOURS UNTIL THE
FRONT PASSES. IFR VISIBILITIES DUE TO HEAVY RAINFALL ALONG WITH
FREQUENT LIGHTNING AND STRONG WINDS WILL ACCOMPANY THE STORMS.
SKIES WILL GRADUALLY CLEAR OVERNIGHT INTO WEDNESDAY
MORNING...HOWEVER STRONG AND GUSTY NORTHERLY WINDS WILL OCCUR.
