AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 414 PM EDT SUN AUG 24 2008 .SYNOPSIS... SCATTERED SHOWERS AND THUNDERSTORMS WILL AFFECT THE FORECAST AREA THIS EVENING AS A WEAK COLD FRONT DRIFTS ACROSS THE REGION. HIGH PRESSURE WILL SPREAD ACROSS THE GREAT LAKES ON MONDAY BRINGING DRIER COOLER WEATHER. THE REMNANTS OF TROPICAL STORM FAY WILL APPROACH THE OHIO VALLEY FROM THE SOUTH BY MIDWEEK. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... COLD FRONT BISECTING NW FCST AREA AT 19Z...ROUGHLY RUNNING FROM JUST SOUTH OF KMNN TO JUST WEST OF KDAY SW INTO SRN INDIANA. SCT TSTMS HAVE DVLPD OVER LAST FEW HOURS INVOF THE BNDRY IN MOIST UNSTABLE CONVERGENT ZONE. TEMPS HAD WARMED INTO THE U80S AND L90S AHEAD OF THE FRNTL BNDRY. LAPS SOUNDINGS INDCG MODERATELY UNSTABLE ATMOSPHERE WITH SBCAPES AT 2000-2500 J/KG IMMEDIATELY AHEAD OF THE FRONT. SPC MESOANALYSIS SHWNG DEEP MOISTURE POOLING AND CONVERGENCE ALONG THETA-E AXIS INVOF FRNTL BNDRY. TSTMS REMAIN SUBSEVERE AS BL SHEAR VALUES HOVERING AROUND 15KTS. WHERE UPR LVL FORCING AND BL SHEAR ARE SLIGHTLY BETTER ACRS NRN OH...HAVE SEEN MORE ORGANIZED AND WIDESPREAD CONVECTION DVLP. MAJORITY OF THIS ACTIVITY IS STAYING JUST NORTH OF THE FCST AREA. EXPECT COVERAGE WILL INCREASE SOMEWHAT FURTHER SOUTHWEST ALONG THE LINE ACRS SRN INDIANA AND INTO WRN FCST AREA OVER NEXT FEW HOURS AS DYNAMICS INCREASE AHEAD OF APPCHG MID LVL S/WV. 12Z GFS/NAM/RUC ALL INDCG UPR LVL SPEED MAX DVLPG ON LEE SIDE OF APPCHG S/WV ERLY THIS EVNG...WHICH WILL LIKELY NOT ONLY INCREASE CONVECTIVE COVERAGE BUT ALSO SUSTAIN IT INTO THE EVNG HOURS AS THE FRONT SAGS SOUTHEAST SLOWLY. MODEL SOUNDINGS CONTINUE TO SHOW POTENTIAL FOR STRONGER STORMS TO PULSE CLOSE TO SVR LIMITS...AS MAX DELTA THETA-E VALUES RISE INTO THE LOW 20S THRU 00Z. HOWEVER...BIGGEST IMPACT FROM THESE STORMS WILL BE THE POTENTIAL FOR TORRENTIAL RAINFALL. ATMOSPHERE IS QUITE MOIST AHEAD OF THE FRONT EVIDENCED BY TDS CLIMBING INTO THE U60S AND PWATS BTWN 1.75 AND 2 INCHES. WITH STORM MOTIONS PROGGED AT AROUND 10KTS...STORMS WILL NOT BE QUICK MOVERS. STORMS WILL PROVIDE A BREAK FROM THE MUGGY CONDITIONS AND MORE IMPORTANTLY PRODUCE BENEFICIAL RAINS TO THOSE LUCKY ENUF TO BE UNDERNEATH THEM. FRONT WILL CONTINUE TO PASS SOUTHEAST ACRS FCST AREA TONIGHT WITH TSTMS GRADUALLY DECREASING IN COVERAGE AND INTENSITY AS UPR LVL ENERGY PASSES TO EAST OF REGION AFT MIDNIGHT. WILL MAINTAIN CHC POPS ALL NIGHT NEAR AND SOUTH OF THE OHIO RIVER...AS FRNTL BNDRY NOT LIKELY TO CLR THESE AREAS UNTIL CLOSER TO DAYBREAK. FURTHER NORTH...MUCH DRIER AIR WILL BEGIN ADVECTING INTO THE REGION. SKIES WILL BECOME MSTLY CLR ACRS NRN 1/2 FCST AREA LATE AS SFC HI BEGINS EXERTING ITS INFLUENCE. TEMPS...WARMER MET GUID WAS PREFERRED FOR LOWS TONIGHT. WHILE TEMPS WILL HOLD IN THE M/U60S ACRS SRN FCST AREA...EXPECT TEMPS TO FALL BACK TO WITHIN A FEW DEG EITHER SIDE OF 60 DEG FURTHER NORTH. && .SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY/... CLOUDS AND POSSIBLY AN ISOLD -SHRA OR TWO WILL LINGER ACRS FAR SRN FCST AREA AS FRNTL BNDRY CONTINUE TO PUSH SOUTH. FRONT WILL DROP FURTHER SOUTH INTO KENTUCKY DURING THE DAY BEFORE DISSIPATING AS IT RUNS INTO REMNANTS OF FAY ACRS LWR MISSISSIPPI VLY AND UPR LVL STEERING CURRENTS ARE LOST. ELSEWHERE ACRS THE REGION...MONDAY SHAPING UP TO BE A SPECTACULAR DAY WITH A MUCH DRIER AND SLIGHTLY COOLER AIRMASS OVERSPREADING MUCH OF THE FCST AREA. LINGERING LO LVL MOISTURE AND PRESENCE OF ONE LAST MID LVL S/WV OVER NE OHIO MAY BE ENUF TO POP FEW/SCT CU DURING THE FIRST HALF OF THE DAY. AS DRIER AIR AND GREATER SUBSIDENCE THOUGH ADVECT INTO THE REGION DURING THE AFTN...ANY CU SHOULD QUICKLY BECOME CONFINED TO AREAS NEAR AND SOUTH OF THE OHIO RIVER IN CLOSER PROXIMITY TO WHATS LEFT OF THE FRNTL BNDRY. OUTER REACHES OF CI FROM REMNANTS OF FAY ALSO WILL LIKELY REACH INTO SRN FCST AREA FOR MUCH OF THE DAY. WILL CONTINUE WITH A PTLY SUNNY FCST NEAR AND SOUTH OF THE RIVER AS A RESULT. OTHER THAN CI FROM FAY ACRS SRN 1/3 FCST AREA MON NIGHT...MOST OF THE FCST AREA WILL BE COMPLETELY UNDER THE INFLUENCE OF SFC HI CENTERED OVER THE CNTRL GRT LKS. EXPECT MSTLY CLR SKIES AND LGT WINDS MON NIGHT. FOR TUES...WILL CONTINUE TO LEAN IN FAVOR OF THE GFS/ECMWF SOLN WHICH IS SLOWER WITH NORTHWARD PROGRESSION OF REMNANTS OF FAY TOWARDS THE OH VLY. WITH SFC HI MAKING ONLY SLOW PROGRESS INTO ERN GRT LKS ON TUES...EXPECT SKIES TO REMAIN MSTLY SUNNY INTO THE AFTN HOURS WITH MID/HI LVL CLOUDS SLOWLY INCREASING FROM THE SOUTH DURING THE MID/LATE AFTN. ANY PCPN ASSOCD WITH APPCHG SFC INV TROF FROM FAY WILL REMAIN SOUTH OF THE FCST AREA INTO TUES EVNG. TEMPS...TOOK SPLIT OF COOLER MET AND WARMER MAV GUID FOR AFTN HIGHS MON...WITH TEMPS EXPECTED IN THE U70S AND L80S. MON NIGHT HAS THE POTENTIAL TO BE REALLY COOL ACRS THE NORTH UNDER ALMOST IDEAL RADIATIONAL COOLING CONDITIONS. SOME RURAL LOCATIONS ACRS NRN 1/2 FCST AREA MAY GET CLOSE TO 50 DEG BY TUES MRNG. CLOSE TO MOS GUID FOR TEMPS ON TUES. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... HAVE AGAIN TAKEN A BLEND OF THE OPERATIONAL GFS...ECMWF AND HPC GUIDANCE FOR THE UPCOMING LONG TERM FORECAST. OPERATIONAL NAM-WRF CONTINUES TO BE THE OUTLIER IN THAT IT TAKES THE UPPER LEVEL CIRCULATION IN ASSOCIATION WITH THE REMNANTS OF FAY FARTHER WEST THAN THE OTHER MODELS AND ENSEMBLE MEANS...SO HAVE DISCARDED THIS SOLUTION. FOR TUESDAY NIGHT INTO WEDNESDAY NIGHT...UPPER LEVEL CIRCULATION IN ASSOCIATION WITH THE REMNANTS OF FAY WILL PIVOT NE FROM MISSISSIPPI TO THE MIDDLE OHIO VALLEY. BEST CHANCE FOR PCPN CONTINUES TO BE ACROSS THE ERN/SERN FCST AREA. HAVE DELAYED THE ONSET OF PCPN TUESDAY NIGHT SOME...OTHERWISE THE BEST CHANCE FOR PCPN WILL OCCUR FROM LATE WEDNESDAY AFTN INTO WEDNESDAY NIGHT. FORECAST DILEMMA CONTINUES TO BE THE EXACT TRACK OF THE UPPER LEVEL LOW AND ITS ASSOCIATED SFC TO 850 MB INVERTED TROF. THIS SCENARIO WILL LIKELY RESULT IN A TIGHT POP GRADIENT...WHICH IS TOO EARLY AT THIS STAGE TO PINPOINT EXACTLY. HOWEVER...HAVE STARTED THIS TREND BY LAYERING POPS FROM SLIGHT CHANCE ACRS THE FAR NW TO LIKELY POPS SOUTHEAST DURING THE LATE WEDNESDAY AFTN AND EVENING TIME FRAME. GIVEN THAT THIS SYSTEM WILL STILL BE TROPICAL IN NATURE...A WARM RAIN PROCESS IS EXPECTED TO DOMINATE...KEEPING THE THREAT OF THUNDER AT A MINIMUM. TEMPERATURES DURING THIS PERIOD WILL HAVE TO BE TWEAKED SOME MORE AS CONFIDENCE INCREASES IN TERMS OF CLOUD COVER AND PCPN. FOR NOW WILL FORECAST HIGHS IN THE UPPER 70S TO LOWER 80S WITH LOWS GENERALLY IN THE LOWER TO MID 60S. FOR THURSDAY AND THURSDAY NIGHT...MODELS SLOWLY EJECT THE UPPER LOW TO THE ENE IN RESPONSE TO AN UPPER LVL TROF APPROACHING FROM THE NORTHWEST. HAVE DECREASED POPS THROUGHOUT THE DAY THURSDAY... ALLOWING FOR A DRY FORECAST BY THURSDAY NIGHT. FOR FRIDAY AND FRIDAY NIGHT...AN UPPER LEVEL TROF AND ASSOCIATED COLD FRONT WILL PIVOT ACRS THE LOWER GREAT LAKES AND OHIO VALLEY REGION. WILL CONTINUE WITH 30 AND 40 POPS ON FRIDAY...DECREASING THE PCPN CHANCES OVERNIGHT AS THE FRONT MOVES SOUTHEAST OF THE REGION. FINALLY FOR THE REMAINDER OF THE EXTENDED...SATURDAY THROUGH SUNDAY...MODELS AGREE THAT SURFACE HIGH PRESSURE WILL BUILD INTO THE REGION...BRINING DRY WEATHER ALONG WITH SLIGHTLY BELOW NORMAL TEMPERATURES. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... COLD FRONT FROM LAKE ERIE INTO SOUTH CENTRAL INDIANA WILL PUSH ACROSS THE FORECAST AREA THIS AFTERNOON AND EVENING. BEST CONVERGENCE AND INSTABILITY FOCUSED ALONG THE COLD FRONT AND A SCATTERED LINE OF SHOWERS AND THUNDERSTORMS HAD DEVELOPED ALONG THE FRONT EARLY THIS AFTERNOON. WILL CONTINUE TO SEE DEVELOPMENT THIS AFTERNOON INTO EVENING. EXCEPT AT KLUK AND KCVG...WILL MENTION VCTS AND/OR TSTMS FOR A PERIOD FROM ABOUT 19Z TO 23Z AT KDAY AND 02Z AT EASTERN TAF SITES.
