AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 1227 PM EDT FRI JUN 13 2008 .SYNOPSIS... A COLD FRONT WILL APPROACH FROM THE WEST TODAY AND CROSS THE REGION LATE TONIGHT AND EARLY SATURDAY. HIGH PRESSURE WILL THEN BUILD IN FOR THE REST OF THE WEEKEND. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... KILN RADAR AND MOSAIC RADAR THIS MORNING INDICATED SCATTERED SHOWERS AND THUNDERSTORMS FROM THE LOWER OHIO RIVER VALLEY NORTHEAST INTO NORTHWEST OHIO/SOUTHEAST MICHIGAN. THIS ACTIVITY DEVELOPED OVERNIGHT AND EARLY THIS MORNING DUE TO AN ALREADY UNSTABLE AIRMASS AND ALSO DUE TO AN OUTFLOW BOUNDARY EJECTED EASTWARD FROM THE MID MS VLY. CONVECTION WILL TRANSITION FROM ELEVATED TO SURFACE BASED AS DAYTIME HEATING PROGRESSES. MIXED LAYER CAPE VALUES IN THE 1500-2000 J/KG BY MAXIMUM HEATING ARE EXPECTED...WHICH IS IN THE MODERATE RANGE. ALTHOUGH OVERALL BULK SHEAR IS WEAK...AROUND 25 KNOTS...THE MODERATE INSTABILITY AND SUBTLE LOW LEVEL CONVERGENCE BOUNDARIES/OUTFLOW BOUNDARIES SHOULD LEAD TO BETTER THUNDERSTORM COVERAGE AND SLIGHTLY BETTER ORGANIZATION THAN YESTERDAY AFTN. IN ADDITION...MODELS INDICATE SOME WEAK S/WV ENERGY PASSING ACRS INDIANA/LOWER MICHIGAN LATE IN THE DAY...WHICH WILL LIKELY BE CLOSE ENOUGH TO IMPART SOME WEAK UPR LVL FORCING ACRS THE WRN CWFA. A FEW SEVERE STORMS ARE NOT OUT OF THE QUESTION THIS AFTN GIVEN MODERATE INSTABILITY AND DELTA THETA E VALUES AROUND 25 KELVIN. DAMAGING WINDS AND LARGE HAIL WILL BE THE PRIMARY SEVERE WEATHER THREATS. WITH PWAT VALUES RANGING BETWEEN 1.5 AND 1.75...HEAVY RAINFALL AND SUBSEQUENT LOCALIZED FLOODING WILL BE A THREAT AS WELL. CURRENT FORECAST LOOKS GOOD. THE ONLY CHANGES WILL BE TO USE AREAL COVERAGE WORDING INSTEAD OF PROBABILITY. TEMPS SEEM REASONABLE...RANGING FROM THE MID 80S WEST TO AROUND 90 EAST. && .SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY/... A COLD FRONT WILL PUSH INTO THE REGION OVERNIGHT AND MOVE OFF TO THE EAST ON SATURDAY MORNING. SHOULD HAVE A PRETTY GOOD CHANCE OF SHOWERS AND THUNDERSTORMS WITH THIS FRONT AND HAVE CONTINUED TO GO WITH LIKELY POPS. SHEAR IS FORECAST TO INCREASE SOMEWHAT OVERNIGHT BUT INSTABILITY DECREASES QUITE A BIT. OVERALL LOOKS LIKE THE SEVERE THREAT WILL CONTINUE INTO TONIGHT. PRECIPITATION WILL PUSH OFF TO THE EAST WITH THE FRONT DURING THE MORNING. BUT IT IS NOT OUT OF THE QUESTION THAT REDEVELOPMENT ON SATURDAY AFTERNOON COULD OCCUR IN THE FAR EASTERN ZONES. HIGH PRESSURE WILL THEN BUILD IN RESULTING IN DRY CONDITIONS SATURDAY NIGHT AND SUNDAY. GFS MOS LOOKED REASONABLE FOR TONIGHT. THEN TRENDED TOWARDS ETA MOS IN LATER PERIODS. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... CHANGE IN THE UPPER AIR PATTERN WILL COMPLETED BY A SHORT WAVE DROPPING SOUTHEAST THROUGH THE REGION ON MONDAY. THIS WILL ESTABLISH A TROUGH IN THE NORTHEAST RESULTING IN COOLER TEMPERATURES ACROSS THE OHIO VALLEY FOR MUCH OF THE WEEK. THE SHORT WAVE ON MONDAY WILL PUSH A FRONT THROUGH THE FORECAST AREA BRINGING A CHANCE OF SHOWERS AND THUNDERSTORMS. SEVERAL SHORT WAVES WILL BE DROPPING INTO THE MEAN UPPER TROUGH THROUGH THE REST OF THE PERIOD. AND ANY ONE OF THESE COULD GENERATE SOME SHOWERS. BUT AT THIS TIME THE PROBABILITY IS TOO LOW TO INCLUDE IN THE FORECAST. TEMPERATURES WILL BE NEAR NORMAL SUNDAY NIGHT AND THEN DROP BELOW NORMAL FOR THE REST OF THE WEEK. && .AVIATION /16Z FRIDAY THROUGH TUESDAY/... A COLD FRONT ACROSS THE UPPER AND MID MISSISSIPPI RIVER VALLEY THIS AFTERNOON WILL PUSH ACROSS THE TAF SITES BETWEEN 06Z AND 12Z. IN THE MEANTIME...A VERY MOIST...UNSTABLE AIRMASS WILL INTERACT WITH WEAK LOW LEVEL CONVERGENCE BOUNDARIES AND OUTFLOW BOUNDARIES FROM OTHER THUNDERSTORMS TO PRODUCE SCATTERED TO NUMEROUS THUNDERSTORMS ACROSS THE TAF SITES THROUGH AT LEAST 02Z. AS A RESULT...WILL USE TEMPO THUNDER GROUPS AT ALL TAF SITES...MAINLY IN THE 20 TO 24 Z TIME FRAME. FOR TONIGHT...AS THE COLD FRONT TRAVERSES THE REGION...IT WILL COUPLE WITH SOME UPPER DIVERGENCE FROM THE JET STREAM ALOFT AND ASSOCD MID LEVEL WEATHER DISTURBANCE TO CONTINUE THE THREAT FOR SHOWERS/THUNDERSTORMS. AGAIN HAVE EMPLOYED TEMPO THUNDER GROUPS AT ALL TAF SITES BETWEEN THE 04Z AND 12Z TIME FRAME. THERE WILL ALSO LIKELY BE A PERIOD OF PREDOMINANT RAIN SHOWERS AND HAVE THUS INCLUDED THIS. AVIATORS CAN EXPECTED MVFR CIGS AND MVFR/IFR VSBYS WITH THUNDERSTORMS. A SURFACE RIDGE OF HIGH PRESSURE WILL BUILD IN THE WAKE OF THE FRONTAL PASSAGE ACROSS THE OHIO VALLEY REGION BETWEEN 12Z AND 18Z SATURDAY. SOME MODELS INDICATE THAT SOME ISOLATED POP OF SHOWERS MAY DEVELOP IN THE AFTN ALONG A WEAK LOW LVL CONVERGENCE BOUNDARY. THIS IS TOO SMALL TO BE CONCERNED WITH AT THIS TIME AND SO HAVE NOT MENTIONED IT IN THE TAFS. ANY MVFR VSBYS IN MIST EARLIER ON WILL CLEAR OUT...LEAVING VFR CONDITIONS BY MID MORNING SATURDAY. OUTLOOK...SHOWERS AND THUNDERSTORMS POSSIBLE ON MONDAY. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE. IN...NONE. && SYNOPSIS...HICKMAN NEAR TERM...HICKMAN SHORT TERM... LONG TERM...
