Area forecast discussion, May 20, 9:43 PM CDT, 1 hour 59 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
943 PM CDT FRI MAY 20 2011

.DISCUSSION...
WENT AHEAD AND CANCELED TORNADO WATCH 315 DUE TO LACK OF
INSTABILITY OVER AREAS THAT HAVE BEEN PREVIOUSLY MODERATED DUE TO
SIGNIFICANT RAINFALL OVER THE PAST SEVERAL HOURS. HOWEVER...COULD
SEE A FEW ISOLATED INSTANCES OF STORMS BECOMING SEVERE OVER THE
NEXT SEVERAL HOURS AS THE UPPER-LEVEL IMPULSE SWEEPS NORTHEAST.
OTHERWISE...MADE A FEW EDITS TO OVERNIGHT TEMPERATURES TO ADJUST
FOR RAIN COOL AREAS. /05/

&&

.AVIATION...
A LARGE AREA OF RAIN AND SCATTERED TSTMS ACROSS NORTHEAST TX INTO
SOUTHWEST AR AND SOUTHEAST OKLAHOMA WAS CREATING MVFR AND IFR FLIGHT
CONDITIONS ALONG WITH GUSTY WINDS AND TURBULENCE. THIS AREA OF RAIN
WILL SPREAD EAST VERY SLOWLY THROUGHOUT THE REMAINDER OF THE EVENING
INTO THE EARLY MORNING HOURS. OUTSIDE OF THIS CONVECTIVE AREA...
FLIGHT CONDITIONS WERE VFR. WINDS GENERALLY SOUTH TO SOUTHEAST
AROUND 10 KTS...BUT WINDS VICINITY OF TSTMS HAVE BEEN VARIABLE IN
DIRECTION...GUSTING TO 35 KTS. EXPECT WIDESPREAD MVFR CIGS AND
SOME IFR TO DEVELOP ACROSS THE REGION AFTER 08Z...CONTINUING TO AT
LEAST 15Z. NO WIND SHIFT EXPECTED WITH THIS CONVECTIVE EVENT...SO
SURFACE WIND ON SATURDAY MOSTLY SOUTH AT 10 TO 15 KTS. /14/
