AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 417 PM EDT SAT SEP 8 2007 .SYNOPSIS... SHOWERS AND THUNDERSTORMS ARE EXPECTED TONIGHT AND SUNDAY AS LOW PRESSURE MOVES ALONG A FRONTAL BOUNDARY ACROSS THE REGION. THE FRONT WILL DROP SOUTH SUNDAY NIGHT...WITH RAIN ENDING AS WEAK HIGH PRESSURE BUILDS IN. RAIN WILL RETURN MONDAY NIGHT AS FRONT LIFTS BACK TO THE NORTH. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... FRNTL BNDRY CURRENTLY LOCATED FROM NRN OH SW THRU CNTRL INDIANA AND BACK INTO SRN ILLINOIS. WITH FILTERED HEATING AND INCREASING LO LVL CONV...TSTM COVERAGE HAS INCREASED ALONG THE BNDRY AND IN THE WARM SECTOR. TEMPS WERE GENERALLY IN THE 80S ACRS MUCH OF THE FCST AREA. SOUTH OF THE OHIO RIVER WHERE LESS CLOUDS WERE PRESENT...TEMPS WERE HOVERING AROUND 90 DEGREES. SFC WAVE CURRENTLY LOCATED NEAR KSTL WILL BE FOCUS FOR SHRA/TSRA ACTIVITY INTO THE OVERNIGHT AS IT TRACKS NORTHEAST ALONG FRNTL BNDRY. MODEL CONSENSUS FAVORING LITTLE MOVEMENT TO CURRENT PLACEMENT OF BNDRY...WITH SFC LO TRACKING THRU CNTRL INDIANA TO NW OHIO BY 12Z SUN. MLCAPES TO NEAR 1000 J/KG AND LO LVL CONV CONTRIBUTING TO NUMEROUS SHRA/TSRA THIS AFTN. AS EVNG PROGRESSES...FOCUS WILL SHIFT MORE TOWARDS NW FCST AREA INVOF FRNTL BNDRY. 30KT 850 LLJ DVLPG AHEAD OF SFC LO LATE TONIGHT WITH ENHANCED LO LVL CONV DVLPG ALONG BNDRY AND INTO WEST CNTRL OH. PWATS CLIMB TO AROUND 2 INCHES LATE TONIGHT IN THIS AREA...WITH POTENTIAL FOR HVY RAINFALL. MERCER/AUGLAIZE/HARDIN COS WERE MAIN COUNTIES AFFECTED BY HVY RAINS BACK IN LATE AUG...BUT RECENT STRETCH OF DRY WX HAS ALLOWED CONDITIONS TO DRY OUT NICELY IN THOSE AREAS. THEREFORE DESPITE POTENTIAL FOR EXTENDED PERIOD OF SHRA/TSRA PRODUCING HVY RAIN LATE TONIGHT...HAVE HELD OFF ON ISSUING A FLASH FLOOD WATCH ATTM. WILL CONTINUE TO MONITOR PCPN EVOLUTION AND AMOUNTS OVERNIGHT. HAVE PLACED CAT POPS IN WEST CNTRL OH TONIGHT...WITH LKLY POPS ACRS MUCH OF THE REST OF THE FCST AREA. OVER SOUTH CNTRL OH/NE KENTUCKY...HAVE LEFT LO CHANCE POPS IN FOR TONIGHT AS APPEARS THERE WILL BE AN EXTENDED PERIOD OF DRY WX FOR GOOD PART OF THE NIGHT WITH PCPN INCREASING IN COVERAGE LATE AS SFC LO APPCHS FROM THE WEST. TEMPS...LOWS HAVE BEEN NEAR WARMER MET GUID LAST SVRL NIGHTS AND WITH MOIST AIRMASS IN PLACE AGAIN TONIGHT...WILL KEEP TEMPS TOWARDS HIGHER END OF GUID WITH LOWS IN THE U60S/L70S. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/... SFC WAVE WILL MAKE SLOW PROGRESS EAST ACRS FCST AREA ON SUN AS FRNTL BNDRY SLOWLY SAGS SOUTH. BEST FORCING REMAINS FOCUSED ACRS NRN FCST AREA INVOF SFC LO...AND THIS SHOULD RESULT IN MOST WIDESPREAD PCPN RESIDING ALONG AND NORTH OF INTERSTATE 70 IN THE MRNG. SHOULD SEE PCPN THOUGH JUST ABOUT EVERYWHERE ACRS FCST AREA AS LO LVL CONV AXIS SWINGS ACRS REGION AHEAD OF APPCHG FRNTL BNDRY. SVR TSTMS ARE NOT EXPECTED AS ABUNDANCE OF CLOUDS AND LACK OF ANY SIGNIFICANT INSTABILITY WILL BE LIMITING FACTORS. WHILE GREATEST AMOUNTS OF RAINFALL SHOULD REMAIN FOCUSED CLOSER TO SFC LO ACRS NRN FCST AREA...DOES APPEAR THAT SRN OH/NRN KY WILL SEE THE CHANCE FOR SOME MUCH NEEDED RAINFALL. NOT A DROUGHT BUSTER BY ANY MEANS...BUT ANY RAIN WILL HELP ATTM AS KCVG CURRENTLY SITTING AT MORE THAN 12 INCHES BELOW NORM FOR THE YEAR ON PCPN. SFC LO WILL SHIFT EAST OF THE FCST AREA DURING THE AFTN HOURS...WITH PCPN COVERAGE DIMINISHING FROM WEST TO EAST DURING THE LATE AFTN AND EVNG. SOME LINGERING -SHRA ARE POSSIBLE ACRS FAR SRN/ERN SECTIONS OF FCST AREA DURING THE EVNG AS THE FRONT DROPS SOUTH OF THE OHIO RIVER. EXPECT SC TO LINGER BEHIND THE FRONT FOR MUCH OF THE NIGHT WITH ONLY SLOW CLEARING FROM THE NORTH AS WEAK SFC HI BUILDS IN. INFLUENCE OF THE HIGH WILL HOLD FOR MON WITH PTLY CLDY SKIES AS FRNTL BNDRY DROPS SOUTH INTO THE TN VLY. DIGGING UPR TROF OVER NRN PLAINS WILL BEGIN TO PROGRESS EAST MON NIGHT AS S/WV ENERGY DIVES INTO THE MID MISSISSIPPI VLY. FAVORED 12Z GFS/ECMWF SOLNS...BOTH WHICH ARE MORE PROGRESSIVE WITH TROF MON NIGHT INTO TUES. SW UPR FLO AHEAD OF THE TROF WILL ALLOW MOISTURE OVER THE MID MISSISSIPPI/TN VLYS TO BEGIN FUNNELING BACK NORTHEAST INTO THE REGION MON NIGHT AS SFC WAVE SPINS UP ALONG BNDRY. HAVE THEREFORE BROUGHT CHANCE POPS BACK INTO FCST AREA LATE MON NIGHT INTO TUES MRNG...WITH GREATEST COVERAGE TO PCPN EXPECTED OVER SRN 1/2 FCST AREA AS AFOREMENTIONED SFC WAVE PASSES THRU KENTUCKY. WITH EXCEPTION OF A FEW TSTMS...BULK OF PCPN SHOULD BE IN THE FORM OF SHRA DUE TO LACK OF INSTABILITY. TEMPS...LEANED TOWARDS WARM END OF GUID FOR SUN AND MON WITH TEMPS IN THE U70S AND L80S. LOWS WILL SLIDE BACK INTO THE U50S AND L60S. && .LONG TERM /TUESDAY THROUGH SATURDAY/... HAVE USED A BLEND OF THE LATEST 12Z GFS OPERATIONAL MODEL AND THE 00Z GFS ENSEMBLE MEAN FOR THE EXTENDED FORECAST. THE UPPER LEVEL FLOW PATTERN THROUGH THE WEEK WILL FEATURE A W TO NW FLOW ALOFT. A TANDEM OF S/WVS IN THE FLOW ALOFT WILL ARRIVE ON TUESDAY. THE STRONGER S/WV IS FCST TO MOVE THROUGH THE OHIO VALLEY REGION...PERTURBING A SFC WAVE OF LOW PRESSURE ACRS KENTUCKY. THE WEAKER S/WV WILL PASS ACRS THE SRN GREAT LAKES. ALL IN ALL...SKIES WILL BE MOSTLY CLOUDY WITH A CHANCE OF SHOWERS FOR MOST OF THE REGION...EXCEPT ALONG AND SOUTH OF THE OHIO RIVER WHERE BETTER INSTABILITY MAY RESULT IN A THUNDERSTORM. FRONTAL WAVE WILL PASS QUICKLY TO THE ENE TUESDAY NIGHT. THIS WILL ALLOW SFC HIGH PRESSURE TO BUILD INTO THE REGION...WHICH WILL RESULT IN CLEARING SKIES. FOR THE PERIOD WEDNESDAY THROUGH WEDNESDAY NIGHT...SFC HIGH PRESSURE WILL MOVE EAST...AND WILL BE OFF THE NEW ENGLAND COAST BY THURSDAY MORNING. THEREAFTER...A COLD FRONT WILL PASS THROUGH THE REGION SOMETIME LATE THURSDAY INTO THURSDAY NIGHT. THE FRONT WILL LIKELY PASS THROUGH THE REGION DRY AS ASSOCIATED UPPER LEVEL DYNAMICS REMAIN WELL TO THE NORTH. FOR THE REMAINDER OF THE EXTENDED...FRIDAY THROUGH SATURDAY...OPERATIONAL GFS CONTINUES TO DEVELOP A CLOSED LOW ACRS THE PLAINS...SLOWLY PUSHING THIS SYSTEM INTO OUR REGION FOR THE WEEKEND. THE OPERATIONAL GFS HAS THE PROPENSITY OF OVERDEVELOPING CLOSED LOWS. THUS...WILL NOT BUY INTO THIS SOLUTION YET. WILL LEAN TOWARD THE GFS ENSEMBLE MEAN WHICH BRINGS A MEAN UPPER LVL TROUGH THROUGH THE GREAT LAKES. WILL INTRODUCE A SMALL CHANCE OF SHOWERS ATTM DUE TO THE UPPER LVL TROUGH. AS FOR TEMPERATURES...HIGHS WILL BE BELOW NORMAL EARLY ON...RISING TO AT OR SLIGHTLY ABOVE LATE IN THE WEEK...THEN WILL DROP BACK TO BELOW NORMAL READINGS FOR THE WEEKEND. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... A WARM FRONTAL BOUNDARY WILL REMAIN NEARLY STATIONARY ACROSS NORTH CENTRAL OHIO AND INDIANA THROUGH THE OVERNIGHT HOURS. A SURFACE WAVE SHOULD DEVELOP NEAR MO THIS EVENING...THEN RIDE UP ALONG THE FRONT TO BE POSITIONED NEAR THE CENTRAL IN/OH BORDER BY AROUND 15Z SUNDAY. THE WARM FRONTAL BOUNDARY...WELL NORTH OF OUR TAF SITES...WILL BE THE PRIMARY FOCUS FOR CONVECTIVE ACTIVITY THROUGH TONIGHT. EXPECT SOME SCATTERED CONVECTION IN THE WARM SECTOR DURING PEAK HEATING TODAY AND INTO THIS EVENING. THIS CONVECTION COULD IMPACT THE TAF SITES THROUGH THIS EVENING. AFTER THIS EXPECT THE WARM SECTOR CONVECTION TO DIMINISH GIVEN THE LACK OF GENERAL FORCING. AS THE SURFACE WAVE APPROACHES THE AREA LATE TONIGHT AND EARLY SUNDAY...EXPECT THE CHANCES FOR PRECIPITATION TO INCREASE. INSTABILITY SHOULD BE AT A MINIMUM...SO EXPECT A CHANCE OF SHOWERS WITH EMBEDDED THUNDERSTORMS. EXPECT MAINLY VFR CONDITIONS THROUGH THIS EVENING EXCEPT IN STORM CORES. AFTER 06Z...EXPECT MVFR CONDITIONS TO AFFECT THE TAF SITES FROM WEST TO EAST IN ASSOCIATION WITH THE APPROACHING SURFACE WAVE. EXPECT MVFR CONDITIONS TO PERSIST DURING MOST OF THE 12Z-18Z PERIOD AS THIS SURFACE WAVE MOVES SLOWLY ACROSS THE AREA. OUTLOOK...CHANCE OF THUNDERSTORMS TUESDAY. && .CLIMATE... KCVG MADE IT TO 90 DEG YET AGAIN TODAY...MARKING THE 46TH DAY THIS YEAR THAT TEMPS HAVE MADE IT TO 90 DEG OR WARMER AT KCVG. THIS TIES THE 46 DAYS OF 90 DEG OR BETTER AT KCVG IN 1983 AND 1988. THE LAST YEAR THAT WITNESSED MORE 90 DEG DAYS WAS 1959...WHEN THE TEMPERATURE REACHED 90 DEG 47 TIMES.
