AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
245 PM CDT WED MAR 14 2012

.SHORT TERM...(THIS EVENING THROUGH THURSDAY NIGHT)
ISSUED AT 245 PM CDT WED MAR 14 2012

PER SPC/S RECENT MESOSCALE DISCUSSION IT DOES NOT SOUND LIKE A
SEVERE THUNDERSTORM WATCH WILL BE ISSUED FOR OUR AREA TODAY. WILL
CONTINUE TO MONITOR FOR PULSY SEVERE CELLS...BUT WITH LITTLE MORE
WARMING LIKELY AND NO OTHER HELP TO WIPE OUT THE CAP...WE MAY NOT
SEE AS MUCH COVERAGE AS PREVIOUSLY EXPECTED. THE CAP IS STRONGER
THAN EXPECTED BECAUSE THE SURFACE AIRMASS HAS GOTTEN WARMER/JUICIER
THAN FORECAST. RECORDS HAVE BEEN SET AT KEVV AND KPAH TODAY.

COULD SEE SOME LINGERING SHOWERS OR STORMS OVER PORTIONS OF THE
AREA FOR A FEW HOURS THIS EVENING...BUT FEEL THAT MOST OF THE AREA WILL
BE DRY FOR MUCH OF THE NIGHT. THE 12Z MODELS CONTINUE TO DISAGREE
FOR PLACEMENT OF DEVELOPMENT LATER TONIGHT. THE NAM IS LIMITED TO
THE FAR WEST VERY LATE...WHILE THE GFS HAS MORE WIDESPREAD
DEVELOPMENT THROUGHOUT THE AREA. SHOWED A MINOR INCREASE LATE
TONIGHT...BUT NOT SURE ABOUT THE COVERAGE OF THE GFS.

LOOKS LIKE ONE MAIN DISTURBANCE WILL MOVE SLOWLY EAST THROUGH THE
AREA THURSDAY. THE PRIMARY FOCUS WILL BE IN THE SOUTHERN HALF
OF THE AREA...WHERE LIKELIES HAVE BEEN POSTED. THE SURFACE AIRMASS
SHOULD NOT BE AS ENERGIZED AS TODAY DUE TO INCREASED CLOUDS AND
PRECIPITATION...SO WOULD NOT EXPECT MUCH CHANCE OF A SEVERE STORM
THURSDAY.

THE FOCUS LINGERS OVER THE SOUTHEAST HALF OF THE AREA THURSDAY
NIGHT AND FRIDAY AS MINOR DISTURBANCES CONTINUE TO SLIP SOUTHEAST
THROUGH THE REGION. WOULD EXPECT LESS CLOUD COVER OVER THE AREA
FRIDAY...SO INSTABILITY MAY INCREASE ENOUGH TO MONITOR FOR A STRAY
PULSE SEVERE STORM AGAIN.

LATE FRIDAY NIGHT THROUGH SATURDAY THE UPPER RIDGE BEGINS TO
ASSERT ITSELF OVER THE REGION...WHICH SHOULD PUSH ANY REAL CHANCES
OF CONVECTION TO THE NORTH AND NORTHEAST.

GENERALLY FOLLOWED THE CONSENSUS OF RAW MODEL DATA FOR
DEWPOINTS...AS THE MOS JUST DOES NOT SEEM TO BE ABLE TO HANDLE
THIS ABNORMALLY MOIST SITUATION. USED RAW MODEL DATA FOR LOWS
THROUGH FRIDAY NIGHT...AND MOS SEEMED TO BE THE BETTER CHOICE
FRIDAY AND SATURDAY. RAW MODEL TEMPERATURES SEEMED TO HOLD
TEMPERATURES DOWN A BIT MORE REALISTICALLY FOR THURSDAY
HIGHS...GIVEN THE CLOUD COVER AND PRECIPITATION EXPECTED.

.LONG TERM...(FRIDAY THROUGH WEDNESDAY)
ISSUED AT 245 PM CDT WED MAR 14 2012

CONTINUATION OF UNSEASONABLY WARM TEMPS WILL CONTINUE AS UPPER RIDGE
STRENGTHENS ACROSS THE EASTERN STATES. GENERALLY DRY CONDITIONS ARE
EXPECTED THROUGH TUESDAY...THEN THE MODELS BEGIN TO DIVERGE WITH
THEIR HANDLING OF THE DEEP TROUGH IN THE WEST. THE SLOWEST AND
DRIEST SOLUTION IS OFFERED BY THE 12Z GFS ENSEMBLE MEAN...WHICH
SHOWS THE SYSTEM BECOMING A CUT OFF LOW OVER THE SOUTHERN ROCKIES.
THE 00Z ECMWF WAS VASTLY DIFFERENT...WITH THE TROUGH EJECTING
NORTHEAST AND LEAVING A MORE ZONAL FLOW PATTERN IN PLACE BY LATE
NEXT WEEK. GIVEN THESE TREMENDOUS DIFFERENCES...THE FORECAST FOR
WEDNESDAY WILL HAVE LOW CHANCE POPS AS A COMPROMISE. THE FINAL
OUTCOME WILL PROBABLY LIE SOMEWHERE BETWEEN THE EXTREMES OFFERED BY
THE ABOVE MODELS.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY AFTERNOON)
ISSUED AT 1215 PM CDT WED MAR 14 2012

SHOULD SEE SIGNIFICANT CU FIELD...LOW VFR...ACROSS THE ENTIRE AREA
THIS AFTERNOON...AS MOST AREAS QUICKLY HIT CONVECTIVE TEMPERATURE.
THERE IS NO BOUNDARY OR SIGNIFICANT DISTURBANCE TO REALLY FOCUS
THUNDERSTORM DEVELOPMENT THIS AFTERNOON...SO WILL JUST MENTION A
CB AT ALL SITES THROUGH THE AFTERNOON AND AMEND AS NECESSARY ONCE
THEY DEVELOP.

THE 12Z MODELS LOOK RATHER DRY FOR MUCH OF THE AREA TONIGHT...BUT
IT IS NOT A VERY CONFIDENT SITUATION. WILL KEEP THE TAFS DRY...BUT
MENTION A CB LATE TONIGHT IN THE WEST. LOOKS LIKE AT LEAST
SCATTERED DEVELOPMENT EARLY THURSDAY...SO INSERTED A PROB30 AT ALL
SITES WITH MVFR CONDITIONS IN TSRA.
