AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 236 PM CDT TUE APR 28 2009 .SHORT TERM /TONIGHT THROUGH FRIDAY/... SHOWERS STEADILY DIMINISHED THROUGH THE MORNING...AND ONLY ISOLATED ACTIVITY REMAINED AS OF 19Z. MODEL SOUNDINGS AND WATER VAPOR IMAGERY INDICATE THAT THIS IS IN RESPONSE TO MID AND UPPER LEVEL DRYING. BREAKS IN THE LOW CLOUDS WERE INCREASING STEADILY WITH AFTERNOON HEATING. HOWEVER...LOW LEVEL MOISTURE IS EXPECTED TO REMAIN HIGH AS A SURFACE FRONT STALLS IN THE VICINITY OF THE OHIO RIVER. BOTH THE 12Z NAM AND GFS KEEP SURFACE WINDS SOUTH TO SOUTHWEST AT KPAH. WITH EXTENSIVE LOW LEVEL MOISTURE...REDEVELOPMENT OF LOW CLOUDS AND FOG IS LIKELY OVERNIGHT. SOME LINGERING LIGHT SHOWERS AND MAYBE A THUNDERSTORM WILL PERSIST TONIGHT AS MOIST BUT WEAK 850 MB FLOW OVERRUNS THE FRONTAL BOUNDARY. QPF WILL BE MUCH LIGHTER THAN LAST NIGHT. ON WEDNESDAY...THE FRONT WILL RETURN NORTH AS A WARM FRONT. SCATTERED SHOWERS WILL CONTINUE AS MID AND UPPER LEVEL MOISTURE BEGINS TO INCREASE ONCE AGAIN. THOUGH INSTABILITY WILL INCREASE SLOWLY WITH DAYTIME HEATING AND INCREASING SOUTH FLOW...AFTERNOON CAPE VALUES ARE STILL FORECAST TO BE RATHER WEAK /GENERALLY LESS THAN 1000/. SOUTH FLOW WILL LIKELY RAISE TEMPS BACK TO ABOVE NORMAL LEVELS DESPITE ABUNDANT CLOUDS. USED A BLEND OF GFS AND NAM MOS. WEDNESDAY NIGHT AND THURSDAY...IT APPEARS A HEAVY RAINFALL EVENT IS LIKELY SOMEWHERE OVER THE MID MISSISSIPPI VALLEY. TIMING AND PLACEMENT OF THE HEAVY QPF VARIES GREATLY FROM ONE MODEL TO THE NEXT. 00Z HPC DAY 3 QPF FAVORED THE LOWER OHIO VALLEY FOR HEAVY RAIN...WITH 1.5 TO 2 INCHES. HOWEVER...12Z NAM AND GFS WERE CONSIDERABLY FASTER AND FURTHER NORTH WITH THE HEAVIEST RAIN. PREFER THE TIMING OF THE 12Z NAM...WHICH SHOWS A 500 MB SHORTWAVE MOVING EAST ACROSS THE MID MISSISSIPPI VALLEY THURSDAY. SOME TYPE OF MCS WILL LIKELY FORM OVER THE PLAINS WEDNESDAY EVENING...FED BY A RESPECTABLE LOW LEVEL JET. THE LOW LEVEL JET AND MCS WILL PROPAGATE EAST ACROSS THE MID MISSISSIPPI VALLEY LATE WEDNESDAY NIGHT/EARLY THURSDAY. PER THE HPC QPF RULE OF THUMB...MODEL QPF IS USUALLY TOO FAR NORTH IN THESE SITUATIONS WHEN A SOUTH/SOUTHWEST LOW LEVEL JET OCCURS. THEREFORE...WILL ADJUST THE NAM QPF SOUTHWARD...AND HAVE LIKELY POPS WEDNESDAY NIGHT AND THURSDAY FOR THE NORTHERN HALF OF THE FORECAST AREA. CHANCE POPS WILL SUFFICE FOR SW KENTUCKY AND FAR SE MISSOURI. DUE TO RECENT HEAVY QPF IN PARTS OF SE MISSOURI AND SW ILLINOIS...HEAVY RAINFALL POTENTIAL WILL BEAR CLOSE WATCHING. THURSDAY NIGHT AND FRIDAY...STRONG SOUTHWEST LOW LEVEL JET WILL PERSIST ACROSS THE LOWER OHIO VALLEY. LITTLE IN THE WAY OF A FORCING MECHANISM IS APPARENT IN MODEL DATA UNTIL A STRONG SYSTEM APPROACHES FROM THE NORTHWEST FRIDAY AFTERNOON. TIMING OF THIS SYSTEM VARIES AMONG MODEL GUIDANCE...WHICH IS DISCUSSED IN LONG TERM SECTION BELOW. GIVEN THE IMPRESSIVE WIND FIELDS AND STRONG FORCING...RISK OF SEVERE CONVECTION EXISTS DESPITE RATHER WEAK INSTABILITY FOR THIS TIME OF YEAR. .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... WET FRONTAL PASSAGE EXPECTED FRIDAY NIGHT...BUT SYNOPTIC EVOLUTION IS IN DOUBT FOR THE WEEKEND AND EARLY NEXT WEEK. THE ECMWF AND GFS DIVERGE SATURDAY THROUGH TUESDAY. THE ECMWF OPERATIONAL RUN IS SUPPORTED BETTER BY ITS ENSEMBLE MEAN...AND HAS BEEN MORE CONSISTENT THAN THE GFS OVER THE LAST 2-3 DAYS. THEREFORE...WILL SIDE WITH HPC AND THE ECMWF FOR THE EXTENDED FORECAST. THE 06Z GFS AND 00Z ECMWF EACH BROUGHT THE COLD FRONT THROUGH THE REGION FRIDAY NIGHT. HOWEVER...THE 12Z GFS HAS SPED BACK UP WITH THE FRONTAL PASSAGE...BRINGING IT IN MOSTLY DURING THE DAY FRIDAY...WHICH IS SUPPORTED BY THE 12Z NAM. FOR NOW WILL CONTINUE TO LEAN TOWARD THE ECMWF...DUE TO ITS BETTER CONSISTENCY...AND PREFERRED EVOLUTION GOING FORWARD. HAVE INCREASED POPS TO LIKELIES THROUGHOUT THE QUAD STATE FRIDAY NIGHT. FOR SATURDAY AND BEYOND...LOOK FOR THE FRONT TO LINGER NOT FAR SOUTH OF THE AREA...AND THE FLOW ALOFT TO GENERALLY BE FAST AND NEARLY ZONAL. THE RESULT WILL LIKELY BE MULTIPLE PERIODS OF ELEVATED SHOWERS AND A FEW THUNDERSTORMS LATE SATURDAY THROUGH TUESDAY...AS INDIVIDUAL DISTURBANCES RIDE THROUGH THE AREA. WILL KEEP LOW CHANCES GOING THROUGOUT THE EXTENDED...AND WAIT FOR BETTER MODEL AGREEMENT/CONFIDENCE BEFORE GOING WITH MORE SIGNIFICANT POPS...OR SOME DRY PERIODS. WITH CLOUDS...PRECIPITATION...AND PERSISTENT EASTERLY LOW-LEVEL FLOW...HIGH TEMPERATURES SHOULD BE AT OR BELOW NORMAL THROUGH THE PERIOD...WHILE LOWS WILL GENERALLY BE AT OR ABOVE NORMAL. && .AVIATION... GRADUAL RISE IN CIGS IS EXPECTED THIS AFTERNOON AS LOW CLOUDS BURN OFF OR LIFT SLOWLY. SOME ISOLATED SHOWERS WILL DEVELOP AS TEMPERATURES WARM UP...AND A FEW STORMS MAY DEVELOP. MOST LOW CLOUDS WILL DISSIPATE SHORTLY AFTER SUNSET WITH THE LOSS OF HEATING. LOW STRATUS AND SOME FOG WILL REDEVELOP LATE TONIGHT DUE TO LIGHT WINDS AND MOIST GROUND. A WEAK FRONT WILL STALL NEAR OR OVER THE TAF SITES THIS EVENING. THIS WILL CAUSE SOUTHWEST WINDS TO BECOME LIGHT AND VARIABLE. && .PAH WATCHES/WARNINGS/ADVISORIES... KY...NONE. MO...NONE. IL...NONE.
