AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
300 PM CDT FRI MAY 13 2011

.DISCUSSION...
UPPER LOW WILL CONTINUE TO MOVE EAST SOUTHEAST TONIGHT...REACHING
THE MID MS RIVER VALLEY BY MIDNIGHT. CLUSTERS OF STRONG TO SEVERE
STORMS ONGOING OVER ERN MO ARE ASSOCIATED WITH A COLD FRONT...AND
WILL MAKE THEIR WAY ACROSS MUCH OF THE REGION LATE TODAY INTO THE
EARLY EVENING. LARGE HAIL AND DAMAGING WIND GUSTS WILL BE THE
PRIMARY CONCERNS...WITH VERY UNSTABLE LI VALUES IN THE MINUS 6 TO
MINUS 8 RANGE ALONG AND WEST OF THE MS RIVER. EVEN MINUS 3 TO MINUS
5 OVER THE REST OF THE FORECAST REGION. 0 TO 6KM BULK SHEAR VALUES
40 TO 45KTS...SO ORGANIZED ROTATING UPDRAFTS WILL BE LIKELY. HOWEVER
WITH SWLY SFC WINDS ALONG WITH VERY LOW 0 TO 1 KM SRH VALUES POINT
TO ONLY A LOW POTENTIAL FOR TORNADO DEVELOPMENT...THO IT IS NOT NIL.
EXPECT ACTIVITY TO BECOME NON SEVERE AFTER SUNSET AS INSTABILITY AND
BULK SHEAR VALUES WANE SUBSTANTIALLY.

ONCE THE UPPER LOW PASSES BY SATURDAY...THE MODELS ARE QUITE
VARIABLE WITH THE EXACT EVOLUTION OF THE H5 PATTERN OVER THE
OHIO VALLEY FOR THE REST OF THE WEEKEND INTO MONDAY. REGARDLESS
OF THE MODEL OF CHOICE...THE IDEA IS...WE WILL STILL BE UNDER THE
INFLUENCE OF A CLOSED DOUBLE BARREL UPPER LOW JUST TO OUR EAST
THROUGH MONDAY. THE RESULT WILL BE LOTS OF CLOUDS ALONG WITH ON AND
OFF CHANCES OF LIGHT RAIN SHOWERS AND MUCH...MUCH COOLER WEATHER
THIS WEEKEND. HIGHEST CHCS OF LIGHT RAINS LOOK TO BE OVER IL/IN
COUNTIES. MAY NOT SEE THE SUN THE ENTIRE WEEKEND OVER MUCH OF THE
REGION.

THE MED RANGE MODELS AND THEIR ENSEMBLES ARE NOT THAT FAR APART IN
THE EXTENDED PERIOD. IN A HIGH AMPLITUDE MID/UPPER LEVEL FLOW...A
LOBE OF MID LEVEL VORTICITY IN THE LONGWAVE TROF OVER THE ERN CONUS
WILL DEPART THE PAH FORECAST AREA ON MON...RESULTING IN A DECREASE
IN RAIN SHOWERS FROM THE WEST...AND MORE BREAKS IN THE CLOUDS.

MON NIGHT WILL PROBABLY BE DRY...EXCEPT PERHAPS IN SWRN IND/KY
PENNYRILE REGION. WITH THE MID/UPPER LOW SO CLOSE TO OUR REGION...
THIS SMALL CHANCE OF PCPN WAS HELD THROUGH TUE...AND ON AND OFF
BEYOND AS WARM ADVECTION ALOFT COMMENCES AHEAD OF YET ANOTHER TIGHT
MID/UPPER LEVEL LOW APPROACHING FROM THE CENTRAL PLAINS. AMOUNTS ARE
EXPECTED TO BE LIGHT THO.

BY FRI...A WARM FRONT SHOULD MOVE NWD THROUGH THE REGION...RESULTING
IN A MINOR INCREASE IN POPS AND A RETURN OF TSTMS TO THE FORECAST.
EXPECT LOTS OF COOL AIR AND SFC HIGH PRESSURE STREAMING SWD THROUGH
THE MS RIVER VALLEY THROUGH TUE...AFTER WHICH THERE WILL BE A
GRADUAL WARMING TREND.

.AVIATION...
CLUSTERS OF STRONG TO POSSIBLY SEVERE STORMS ONGOING THIS AFTN OVER
SE MO AND WILL LIKELY AFFECT AREAS NEAR MOST TAF SITES FROM 20Z
THROUGH 00Z KPAH/KCGI...THEN 00Z TO AROUND 03Z KEVV/KOWB. STORMS MAY
WEAKEN SOMEWHAT AFTER 00Z. WILL LIKELY BE A BREAK TO VFR CONDITIONS
BEHIND THE THUNDERSTORMS...BUT LOW CIGS POSSIBLY IN THE IFR RANGE
WILL WRAP SE INTO THE REGION TOWARD THE END OF THE TAF PERIOD AS
UPPER LOW MOVES OVERHEAD.
