Damaging Wind in Texas, June 19, 2004

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
245 PM CDT SAT JUN 19 2004

.DISCUSSION...
MODELS IN ROUGH AGREEMENT ON THE SHORT TERM. COOL FRONT MOVING INTO
SE CORNER OF OK IS LACKING IN UPPER LEVEL STEERING TO PUSH VERY FAR
INTO THE REGION. THE MCS ASSOCIATED WITH IT THIS MORNING HAS
SCATTERED OUT...ALTHOUGH EXISTING STORMS ARE ON THE STRONG SIDE.
OUTFLOW BOUNDARIES PUSHING INTO CWA RESULTED IN ISOLATED STORMS PAST
COUPLE OF HOURS. THIS ACTIVITY SHOULD INCREASE TOWARDS EVENING WITH
MORE BOUNDARY INTERACTION EXPECTED...AND SOME UPPER SPEED
DIVERGENCE EVIDENT. STILL APPEARS DIURNALLY DRIVEN AND WILL REDUCE
TO SLIGHT CHANCE AFTER MIDNIGHT. MOISTURE DEEPER TODAY ON SOUNDING
THAN WAS YESTERDAY...AND EXPECT IT TO BE EVEN DEEPER TOMORROW.
THUS...40 TO 50 PERCENT AREWIDE EXPECTED...MOST LIKELY EARLIER IN
THE DAY AS STRONG VORT MAX BEGINS MOVING EAST THRU THE AREA.
SUNDAY NIGHT AND MONDAY SHOULD BE FAIRLY QUIET AS FRONTAL
REMNANTS MOVE NORTH OF AREA. THINGS GET INTERSTING AGAIN ON TUESDAY
AS SHORT WAVE IN CENTRAL TX MOVES EAST...AND THE OLD FRONT BEGINS
TO SAG SOUTHWARD ONCE AGAIN. TOUGH TO TELL WHICH FEATURE WILL BE
THE BIGGER PLAYER...BUT FEELING IS THAT WEDNESDAY AND THURSDAY COULD
BE RATHER WET. COULD BE NOCTURNAL IN NATURE AS LARGE VORTEX NORTH
OF THE GREAT LAKES WILL INDUCE A NW FLOW REGIME OVER KS/OK...AND
MODELS INDICATING HIGH DAYTIME INSTABILITY OVER SOUTHERN PLAINS.
THINGS LOOKING RIPE FOR DAYTIME MCS THOSE REGIONS TO MOVE
THIS WAY AT NIGHT...EVEN THOUGH ITS GETTING RATHER LATE IN THE SEASON
FOR THIS SORT OF MISBEHAVIOR.
UPPER LEVEL SHEAR ZONE SINKING SLOWLY THROUGH THE AREA END OF THE
WEEK SHOULD BE FOLLOWED BY SLIGHTLY DRIER AIR...WHICH COULD BE A
DESERVED BREAK FROM RAIN AND HUMIDITY BY NEXT WEEKEND.
