NWS Wilmington, OH wrote its last area forecast discussion before the first event at Apr 7, 6:35 PM EST, 3 hours 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 735 PM EDT WED APR 7 2010 .SYNOPSIS... A DEEP UPPER TROUGH WILL DIG INTO THE CENTRAL PLAINS THROUGH THE EVENING AND OVERNIGHT...WITH ITS ASSOCIATED SURFACE LOW AND AN COLD FRONT DEEPENING AND HEADING NORTHEAST INTO THE LOWER GREAT LAKES AND OHIO VALLEY BY EARLY THURSDAY....BRINGING WIDESPREAD SHOWERS AND A CHANCE FOR THUNDERSTORMS OVERNIGHT. MUCH COOLER TEMPERATURES ARE EXPECTED FOR THE REST OF THE WORK WEEK. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... DEEP CAPPING INVERSION LIFTING THROUGH THE REMAINDER OF THE AFTERNOON...HOWEVER...WITH SFC DEWPOINTS STIL BELOW 60 WITH THE EXCEPTION OF THE NW FCST AREA...LATE AFTERNOON ACTIVITY SHOULD BE SPARSE. THE COLD FRONT BEGINS TO ACCELERATE LATER TONIGHT...BUT TIMING IS EVERYTHING AS THE BEST LL CONVERGENCE BEGINS TO ENTER WESTERN FORECAST AREA AS WE BEGIN TO LOSE THE POTENTIAL FOR SUBSTANTIAL ENOUGH INSTABILITY. GREATEST ML CAPE ONLY APPROACHES ABOUT 400 J/KG...SO WHILE POTENTIAL FOR SEVERE WINDS IS THERE IN ESPECIALLY WESTERN FCST AREA AS LINE FORMS WITH EMBEDDED THUNDERSTORMS...SHOULD STILL BE MARGINAL. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/... FRONT STILL PRETTY SLOPED IN NATURE...SUPPORTING POTENTIAL FOR A PRETTY BROAD AREA OF POST FRONTAL SHOWERS. HAVE EXTENDED THIS CHANCE A LITTLE LONGER INTO THURSDAY THAN PREVIOUS FORECAST...WITH SOME MORNING THUNDERSTORMS STILL POSSIBLE IN THE EAST AS THE COLD FRONT BISECTING THE FCST AREA NEAR 12Z. WEAK PVA AND UPR TROUGH STILL OVER AREA...WITH ENOUGH LL MOISTURE LINGERING TO KEEP CHANCE SHOWERS EVEN INTO THU EVENING IN THE NORTH. WIND GUSTS AS HIGH AS 30 MPH IN THE POST FRONTAL SHOWERS AS WELL. TEMPERATURES WILL BE NEARLY STEADY IN THE NW FCST AREA WITH HIGHS IN THE LOWER 50S...UPPER 50S TO NEAR 60 IN THE EAST. ENOUGH WEAK WITH THE THERMAL TROUGH NOT CLEARING THE FCST AREA UNTIL LATE DAY FRIDAY...STILL PLENTY OF CLOUDS THU NIGHT. TEMPERATURES HAVE THE POTENTIAL TO DROP IN THE MID 30S THROUGH MUCH OF THE NORTHERN FCST AREA. FRIDAY WILL BEGIN TO SEE SOME CLEARING IN THE SW WITH THE APPROACH OF RIDGE IN THE SOUTHERN PLAINS. WITH DECREASING CLOUDS AND DIMINISHING WINDS FRIDAY NIGHT...THIS IS THE BEST NIGHT WITH A FROST CONCERN. IN COORDINATION WITH OHIO AND KY DEPARTMENT OF AGRICULTURE...CROPS ARE NOT THE CONCERN AS THE OFFICIAL FROST FREEZE SEASON HAS NOT BEGUN...BUT POTENTIAL CONCERN RATHER FOR HORTICULTURE/NURSERY COMMUNITY. STILL WILL HIGHLIGHT IN THE HWO. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... EXPECT DRY AND MAINLY CLEAR CONDITIONS THROUGH THE PERIOD WITH HIGH PRESSURE AT THE SURFACE AND ALOFT TAKING OVER THE EASTERN CONUS. CLOUDS MAY INCREASE LATE SUNDAY AND EARLY MONDAY WHEN A WEAK COLD FRONT IS PROGGED TO WASH OUT OVER OHIO. TEMPERATURES WILL GROW WARMER...WITH HIGHS IN THE 60S ON SATURDAY...RISING INTO THE 70S FOR THE REST OF THE PERIOD. WENT ABOVE GUIDANCE...BUT FORECAST MAY BE TOO COOL IF THE RIDGE BUILDS AS STRONG AS IS INDICATED BY MODELS. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... A COLD FRONT IS CURRENTLY APPROACHING THE REGION...WITH A BAND OF CONVECTION STRETCHING FROM SOUTHERN MICHIGAN THROUGH SOUTHERN ILLINOIS. ASIDE FROM SOME LIGHT SHOWERS AHEAD OF THE FRONT...EXPECTING THE MAIN BAND OF PRECIPITATION TO GET INTO THE TAF SITES BETWEEN 03Z AND 05Z. FRONTAL PASSAGE ITSELF WILL THEN BE A FEW HOURS LATER. WINDS ARE GUSTY AHEAD OF THE FRONT FROM THE SOUTHWEST...AND WILL THEN SWITCH TO THE WEST AS THE FRONT PASSES. THE PRECIPITATION LOOKS LIKE IT WILL PROBABLY BE IN THE FORM OF WIDESPREAD SHOWERS...WITH EMBEDDED HEAVY SHOWERS OR THUNDERSTORMS MIXED IN. THE TAF PACKAGE WILL NOT INCLUDE ANY TS AT THIS TIME OWING TO THE FEELING THAT CONVECTION IN THE LINE WILL BE ON AN OVERALL WEAKENING TREND AS IT GETS TOWARD THE AREA...RESULTING IN EVEN LESSER COVERAGE OF THUNDER. AMENDMENTS MAY BE NEEDED ONCE THIS BECOMES MORE CLEAR IN THE NEXT FEW HOURS. MVFR VISIBILITIES AND CEILINGS WILL BE POSSIBLE...AND THIS IS REFLECTED IN THE TAFS. CANNOT RULE OUT IFR CONDITIONS UNDER THE STRONGER CONVECTION. ALTHOUGH THE FORECAST DOES NOT REFLECT IT AT THIS TIME...THERE IS A CHANCE THAT SOME BRIEF CLEARING FOR A FEW HOURS WORKS IN BEHIND THE PRECIPITATION IN THE MORNING HOURS. THIS WOULD OBVIOUSLY INCREASE FLIGHT CATEGORIES BRIEFLY IF SO. WILL LINGER SHOWERS AND MVFR CEILINGS INTO THE DAY THURSDAY...AS COLD AIR BEGINS PUSHING IN AND CAUSES WESTERLY WINDS TO AGAIN BECOME GUSTY. BY THE END OF THE TAF PERIOD THE THREAT FOR RAIN WILL BE ENDING AND CEILINGS SHOULD BECOME DOMINANTLY VFR. OUTLOOK...NO SIGNIFICANT WEATHER EXPECTED. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE. IN...NONE. && SYNOPSIS...JDR NEAR TERM...JDR SHORT TERM...JDR LONG TERM...CONIGLIO AVIATION...HATZOS
