AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 646 AM CDT TUE JUN 14 2011 .UPDATE... UPDATED AVIATION SECTION FOR 12Z TAF ISSUANCE. THE DISCUSSION SECTION IS UNCHANGED FROM THE 421 AM PRODUCT ISSUANCE. && .DISCUSSION... SHOWERS AND NON-SEVERE TSTMS EMBEDDED IN NWRLY MID LEVEL FLOW WERE MOVING INTO THE PAH FCST AREA FROM THE NW THIS MRNG. THIS CONVECTION WILL CONTINUE TO ENCOUNTER A STABLE ENVIRONMENT FOR MUCH OF THE DAY...ESPECIALLY IN THE SWRN HALF OF THE REGION WHICH WILL TEMPORARILY BE UNDER MID LEVEL RIDGING. HOWEVER...NE OF A SFC WARM FRONT LATER IN THE DAY AND INTO THE OVNGT HOURS...ADDITIONAL SHWRS/TSTMS MAY DEVELOP IN CENTRAL IL AND ADJACENT PARTS OF MO AND TRAVEL SEWD INTO MAINLY SRN IL/SWRN IND/ KY PENNYRILE. SOME OF THE STORMS CLOSER TO THE FRONTAL BOUNDARY MIGHT BECOME SEVERE DURING THIS TIME...MAINLY IN THE OVNGT HOURS AS A SHRTWV TROF APPROACHES... THE WARM FRONT MOVES FARTHER EAST...AND ELEVATED INSTABILITY INCREASES. ON WED...THE WARM AND TRAILING COLD FRONTS MAY OCCLUDE OVER THE PAH FCST AREA AS THEY MOVE EWD. AHEAD OF THE COLD FRONT...SFC DEWPOINTS ARE EXPECTED TO INCREASE INTO THE UPPER 60S. IT APPEARS THAT WIND SHEAR AND INSTABILITY ASSOCIATED WITH THE SYSTEM SHOULD BE SUFFICIENT FOR AT LEAST SOME SEVERE TSTM DEVELOPMENT ESPECIALLY IN THE AFTN. SEE THE SPC DISCUSSION FOR DETAILS. THE HIGHEST POPS WILL CONTINUE TO BE IN THE ERN HALF OF THE REGION. UNDER HIGH SFC PRESSURE AND NWRLY MID LEVEL FLOW...THU SHOULD BE DRY FOR OUR AREA...THEN THE MED RANGE MODELS DIFFER ON WHETHER ADDITIONAL SHRTWV ENERGY WILL BREAK DOWN MID LEVEL RIDGING ACROSS THE CENTRAL CONUS...AND PROVIDE PCPN. ATTM...WE CHOSE TO LEAVE THE FORECAST FROM FRI ON MOSTLY UNALTERED...WITH LIMITED POPS. THE TEMP TREND CERTAINLY APPEARS TO BE WARMER. && .AVIATION... VFR CONDITIONS ARE EXPECTED OUTSIDE OF SHOWERS AND THUNDERSTORMS ACROSS THE REGION FOR THE ENTIRE 12Z TAF PERIOD. AS A WEAK WARM FRONT ATTEMPTS TO MOVE THROUGH THE REGION...LIGHT NORTHEAST TO EAST WINDS TO BEGIN THE PERIOD WILL GRADUALLY BECOME MORE SOUTHEAST THROUGH TONIGHT. SPEEDS WILL GENERALLY BE UNDER 10KTS. AS EXPECTED EARLY MORNING STORMS HAVE WEAKENED/DISSIPATED...AS THEY MOVED SOUTHEAST TOWARD KEVV AND KOWB. MAY SEE AN HOUR OR TWO OF LIGHT RAIN AT THESE SITES TO START THE PERIOD...BUT TS NOT EXPECTED AT THIS TIME. CONFIDENCE IS INCREASING IN SHRA/TSRA IN THE 15Z-21Z PERIOD. A DISTURBANCE...WHICH IS RESPONSIBLE FOR NUMEROUS SHOWERS OVER WEST CENTRAL THROUGH EAST CENTRAL MISSOURI AT THIS TIME...WILL LIKELY HELP GENERATE SHRA/TSRA AS IT MOVES SOUTHEAST THROUGH THE REGION AROUND MIDDAY. WITH THE WARM FRONT IN THE VICINITY...SOME HEATING...AND THE AFOREMENTIONED DISTURBANCE...THE COVERAGE OF STORMS TODAY MAY BE PRETTY GOOD. BUT FOR NOW HAVE JUST GONE WITH VFR VCSH/CB IN ALL TAFS TODAY. THE POTENTIAL EXISTS FOR NUMEROUS SHOWERS AND THUNDERSTORMS TO IMPACT THE ENTIRE AREA OVERNIGHT. INSERTED A PROB30 WITH VFR -TSRA AND INDICATED SIGNIFICANT GUSTINESS...AS IT IS LIKELY TO BE FAIRLY ORGANIZED CONVECTIVE SYSTEM WHEN IT MAKES IT THROUGH THE REGION. && .PAH WATCHES/WARNINGS/ADVISORIES...
