AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
217 PM EDT THU JUN 11 2009

.SHORT TERM.../TONIGHT THROUGH FRIDAY/...UPDATED

COMPLEX OF THUNDERSTORMS MOVING NORTHEAST ACROSS THE SOUTHWEST PART
OF THE FORECAST AREA AT 18Z. HAVE HAD A COUPLE OF REPORTS OF TREES
DOWN WITH THE STRONGEST STORMS...AND SEVERE THREAT WILL CONTINUE INTO
THE EVENING...WITH MAIN THREAT BEING WIND DAMAGE AND HAIL. ANOTHER CONCERN
IS THE FLASH FLOOD THREAT. THE 12Z NAM KEEPS 1.5 TO 2 INCH
PRECIPITABLE WATER...PW...ACROSS AREA INTO THE EVENING...AND SREF
MEAN HAS PW IN EXCESS OF 1.5 INCHES THROUGH 21Z OVER THE ENTIRE AREA
AND OVER 1.5 INCHES THROUGH 00Z IN THE NORTHEAST. AS ALREADY NOTED
EARLER THE 12Z NASHVILLE SOUNDING HAD PW OF 1.99 INCHES. ANY
THUNDERSTORMS COULD BE PRODIGIOUS RAIN PRODUCERS. SO FAR THIS
AFTERNOON THE STORMS HAVE BEEN PROGRESSIVE ENOUGH THAT THERE HAVE NOT
BEEN FLASH FLOOD PROBLEMS YET...BUT WITH FLASH FLOOD GUIDANCE
LOW...WILL CONTINUE WITH THE WATCH. FLASH FLOOD GUIDANCE WAS AS LOW
AS 0.5 INCH IN OUR SOUTHWEST COUNTIES THIS MORNING AND THAT DID NOT
TAKE INTO ACCOUNT TODAYS RAIN.

THE 12Z NAM...00Z ECMWF AND 09Z SREF POINT TOWARDS THE FRONT
CURRENTLY TO OUR NORTH FINALLY SLIPPING INTO TN BY FRIDAY
AFTERNOON...WHILE THE 12Z GFS IS SLOWER. WILL GO WITH THE MODEL
CONCENSUS AND ALLOW FRONT TO MOVE SOUTH OF AREA ON FRIDAY. HOWEVER
WITH FRONT STALLING JUST TO OUR SOUTH THIS DETAIL DOES NOT MATTER
TOO MUCH AS SHOWER AND THUNDERSTORM THREAT CONTINUES WITH FRONT SO
CLOSE BY. ONCE PRIMARY MID UPPER LEVEL SHORT WAVE MOVES EAST OF AREA
THIS EVENING THE CHANCE FOR SHOWERS AND THUNDERSTORMS WILL
DIMINISH...BUT WITH FRONT STILL PUSHING SOUTH INTO AREA SOME LOW
LEVEL CONVERGENCE OVERNIGHT COULD RESULT IN SCATTERED SHOWERS AND
THUNDERSTORMS. DO NOT EXPECT MUCH COVERAGE THOUGH AFTER 02Z.

.LONG TERM.../FRIDAY NIGHT THROUGH THURSDAY/...UPDATED

VERY FEW CHANGES TO THE EXTENDED FORECAST THIS AFTERNOON AS AN
ACTIVE PATTERN SHOULD CONTINUE INTO THE EARLY PART OF NEXT
WEEK...BEFORE MORE QUIET WEATHER MOVES IN FOR THE MIDDLE/LATTER HALF
OF NEXT WEEK. MODELS CONTINUE TO STRUGGLE ON EXACT TIMING ANY WAVES
THROUGH THE FLOW FRIDAY NIGHT THROUGH MONDAY AS THE REGION SITS ON
THE EAST SIDE OF AN UPPER RIDGE IN WEST/NORTHWEST FLOW ALOFT. HAVE
ONLY MADE A FEW ADJUSTMENTS TO THE PRECIPITATION CHANCES FOR THE
WEEKEND...TO INCREASE THEM SLIGHTLY IN THE SATURDAY AFTERNOON TIME
FRAME WHERE MODELS SEEM TO AGREE ON THIS BEING A FAVORABLE TIME FOR
SHOWERS/THUNDERSTORMS.

OTHERWISE...LEFT PREVIOUSLY INHERITED PRECIPITATION CHANCE FORECAST
ALONE FOR THE EXTENDED. HIGH PRESSURE OVER THE CENTRAL UNITED STATES
MIGRATES EAST BY MID WEEK BRINGING SOME WARMER AND DRIER WEATHER FOR
THE END OF THE WEEK INTO NEXT WEEKEND. TIMING THE ONSET OF THIS
DRIER PERIOD IS STILL DIFFICULT WITH WIDE VARIETY OF MODEL
SOLUTIONS.

&&

.AVIATION.../18Z TO 18Z/

A LARGE COMPLEX OF THUNDERSTORMS IS ENTERING THE SOUTHWEST PART OF
THE FORECAST AREA AT 1730Z AND WILL BE AFFECTING THE LOZ AND SME
AIRPORTS UNTIL ABOUT 20Z. THE THUNDERSTORMS WILL MOVE NORTHEAST AND
REACH JKL AROUND 20Z. EXPECT IFR CONDITIONS TO PREVAIL WITH THE
HEAVIEST THUNDERSTORMS. BY DUSK...THUNDERSTORMS WILL BE
WANING...WITH FOG OR LOW STRATUS BUILDING IN AS A COLD FRONT SLIDES
SOUTH ACROSS THE AREA. AFTER THE THUNDERSTORMS DIMINISH EXPECT MVFR
TO VFR CONDITIONS FOR A TIME BEFORE THE FOG AND STRATUS BRING
CONDITIONS DOWN TO IFR AND LIFR ACROSS THE AREA TONIGHT.
