Did it verify

Area forecast discussion, Nov 16, 6:00 AM CST, 32 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
600 AM CST WED NOV 16 2011

.DISCUSSION...

TODAY THROUGH THURSDAY NIGHT...

RICH MARINE LAYER WITH LOWER 70S DEWPOINTS IS SURGING NORTHWARD
AHEAD OF A MID LEVEL SHORTWAVE TROUGH EARLY THIS MORNING...AND THIS
HAS BEEN THE FOCUS FOR TORNADO ACTIVITY ACROSS SOUTH CENTRAL MS.
MIXED LAYER CAPE OF 500 TO 1000 J/KG AND HIGH LOW LEVEL SHEAR
ENHANCED BY THE BOUNDARY HAS CHARACTERIZED THE ENVIRONMENT. EXPECT
THE SEVERE WEATHER SET-UP TO RELAX AS THE BETTER LOW LEVEL FLOW AND
TROUGH SHIFTS EAST. MEANWHILE...A COLD FRONT WILL SURGE SOUTHEAST
INTO THE FORECAST AREA FROM THE NORTHWEST BRINGING COLD ADVECTION
AND LIGHT TO MODERATE RAINFALL...ESPECIALLY ACROSS NW/NRN PORTIONS
OF THE ARKLAMISS AS WE GO THROUGH THE MORNING AND INTO THE
AFTERNOON. GUSTY NORTHERLY WINDS WILL USHER IN MUCH COOLER
TEMPERATURES BEHIND THE FRONT THIS AFTERNOON AND TONIGHT.

CLEARING SKIES AND COOL WEATHER WILL BE THE STORY FOR THURSDAY AS
CHILLY HIGH PRESSURE SETTLES OVER THE FORECAST AREA. WITH HIGH
PRESSURE CENTERED OVER THE REGION...EXPECT IDEAL CONDITIONS FOR
NIGHTTIME COOLING THURSDAY NIGHT...LEADING TO A LIGHT FREEZE FOR
MOST OF THE AREA. /EC/

FRIDAY THROUGH TUESDAY...

THE MOSTLY ZONAL AND PROGRESSIVE UPPER LEVEL PATTERN WILL TRANSITION
TO A WRN TROUGH/ERN RIDGE SCENARIO AS WE GO INTO THE WEEKEND AND
EARLY NEXT WEEK...WITH THE GFS/GEFS/ECMWF ALL DEVELOPING A STRONG
SUBTROPICAL RIDGE OVER THE GULF AND SOUTHEAST CONUS. THE RIDGE WILL
HAVE A STRONG PRESENCE OVER THE ARKLAMISS AND IT WILL DEFLECT MUCH
OF THE INITIAL SHORTWAVE ENERGY AND ASSOC RAINFALL TO OUR NW --- BUT
THERE COULD STILL BE SIGNIFICANT RAINFALL OVER THE UPPER ARKLAMISS
DELTA REGION SUNDAY INTO TUESDAY. MEX MOS HIGH TEMPERATURES ARE STILL
ON THE HIGH SIDE OF THE ENSEMBLE MOS RANGE...BUT THIS WARM PATTERN
STRONGLY SUGGESTS WELL ABOVE CLIMATE AVERAGES AND WOULD NOT BE
SURPRISED IF A FEW 80F+ TEMPS ARE RECORDED. /EC/

.AVIATION...A COLD FRONT WILL BRING POOR AVIATION CONDITIONS THROUGH
MUCH OF TODAY...BUT CLEARING SKIES TONIGHT INTO THURSDAY WILL RESULT
IN VFR CONDITIONS FOR MOST OF THURSDAY THROUGH FRIDAY.
