AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 206 PM EDT THU JUL 26 2007 .SYNOPSIS... UPPER LEVEL LOW PRESSURE OVER THE LOWER GREAT LAKES WILL GRADUALLY WEAKEN AND MOVE OFF TO THE EAST. THIS WILL ALLOW A COLD FRONT TO APPROACH FROM THE NORTHWEST ON FRIDAY AFTERNOON AND EVENING. THE FRONT WILL MOVE THROUGH THE AREA LATE FRIDAY NIGHT INTO SATURDAY BRINING A DRIER COOLER AIRMASS FOR THE LATTER HALF OF THE WEEKEND. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... EXTENSIVE CLOUD COVER ACROSS ALL BUT THE FAR SOUTHERN ZONES WAS LIMITING HEATING AND INSTABILITY FOR MOST PLACES. APPEARS THAT THIS WILL CONTINUE TO BE THE CASE. SO WILL LOWER HIGHS FOR THE REST OF THE DAY. THUNDERSTORMS HAVE DEVELOPED IN MORE UNSTABLE AIRMASS IN NORTHERN KENTUCKY AND SHOULD CONTINUE TO MOVE EAST ACROSS THIS AREA. BEST COVERAGE OF PRECIPITATION WILL BE WITH THESE THUNDERSTORMS. ELSEWHERE ISOLATED TO SCATTERED SHOWERS WILL REMAIN POSSIBLE THROUGH THE AFTERNOON. && .SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/... EXPECT ACTIVITY TO DIMINISH TONIGHT WHEN THE UPPER LOW LIFTS FARTHER NORTH AND INSTABILITY DECREASES. AS THE UPPER LOW MOVES EAST INTO NEW YORK STATE ON FRIDAY...STRONGER SURFACE CONVERGENCE WILL COME INTO PLAY AS A FRONT AND AN ASSOCIATED WAVE OF LOW PRESSURE DROP INTO OHIO. THUS...HAVE RAISED POPS TO 60 PERCENT FOR SHOWERS AND THUNDERSTORMS. CHANCE FOR SEVERE WEATHER WILL BE GREATER DUE TO THE AFOREMENTIONED CONVERGENCE...AMPLE DELTA THETA E...AND MORE POTENT WINDS. DRIER CONDITIONS WILL ARRIVE BY LATE SATURDAY AS HIGH PRESSURE FOLLOWS THE FRONT. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... UPR LO TRANSITIONS INTO AN OPEN WAVE AHEAD OF APPCHG COLD FRONT ON FRI.

HAVE INCREASED TO 50 POPS FRI AFTN/NIGHT WITH FRONT IN REGION. 12Z NAM MAINTAINS MUCH STRONGER SFC LO THAT OTHER MODELS...MOVING IT ACRS LWR GRT LKS FRI AFTN INTO ERLY SAT. THIS CONTRIBUTING TO PCPN CHANCES LOWERING MUCH MORE QUICKLY DURING THE DAY SAT. 12Z OP GFS APPEARS TO BE SUFFERING FROM CONVECTIVE FEEDBACK...NOTED BY LARGE PCPN AREA MOVING SLOWLY ACRS FCST AREA FRI NIGHT/SAT MRNG. HAVE INSTEAD TRENDED TOWARDS A BLENDED SOLN THAT WEIGHS HEAVILY TOWARDS ECMWF/00Z GFS ENSEMBLE...WITH FRNTL BNDRY AND ASSOCD SFC WAVES DROPPING ACRS FCST AREA LATE FRI INTO SAT. IF A REASONABLE AMOUNT OF DIURNAL HEATING CAN BE REALIZED FRI AHEAD OF FRNTL BNDRY...BELIEVE POTENTIAL EXISTS FOR SCT SVR CONVECTION DURING AFTN/EVNG HOURS AS BL SHEAR VALUES WILL HOVER AT 20-30 M/S ALONG WITH FAIRLY MODEST FORWARD PROPAGATION SHOULD CONTRIBUTE TO SOME LOCALIZED DMG WINDS. EXTREMELY MOIST AIRMASS AHEAD OF COLD FRONT WITH PWATS APPCHG 2 INCHES WILL ALSO ENSURE LOCALLY HVY RAINFALL THREAT. PCPN CHANCES WILL DWINDLE FROM WEST TO EAST ACRS FCST AREA SAT AFTN/NIGHT AS COLD FRONT SLOWLY SHIFTS EAST OF THE REGION AND IS REPLACED BY WEAK SFC HI PRES. A RETURN TO DRY AND SEASONABLE WX APPEARS TO BE IN ORDER FOR REMAINDER OF LONG TERM PERIOD AS N/NE SFC FLO REESTABLISHES WITH SFC HI LOCKING IN PLACE AS FRONT STALLS ALONG EAST COAST AND ACRS SE CONUS. 12Z OP GFS INTRODUCED NEW IDEA OF YET ANOTHER CUTOFF UPR LO SETTING UP OVER UPR OH VLY BY THE END OF THE WEEKEND IN WAKE OF COLD FRONT...THEN LINGER JUST EAST OF THE FCST AREA FOR THE BETTER PART OF NEXT WEEK IN WEAK FLOW REGIME. HAVE REJECTED THIS SOLN FOR MON-WED TIMEFRAME SINCE 12Z RUN DID HAVE A MYRIAD OF ISSUES (CONV FEEDBACK PROBS FRI FOR EXAMPLE) AND NONE OF THE OTHER EXTENDED MODELS EVEN SUGGESTING SOMETHING CLOSE TO THIS CUTOFF LO SOLN ATTM. WX PATTERN HAS REVERTED TO COOLER/DRIER N/NE FLO IN WAKE OF FROPAS ON NUMEROUS OCCASIONS ALREADY THIS SUMMER (AND PARTICULARLY OVER LAST FEW WEEKS)...SO HAVE HIGHER CONFIDENCE IN TRENDING TOWARDS PERSISTENCE ATTM. WITH OH VLY BTWN TROF CENTERED TO EAST AND RIDGE TO WEST...TEMPS WILL REMAIN NEAR NORMAL THRU THE PERIOD. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... MID CLOUDS WILL PERSIST ACROSS THE REGION THROUGH MUCH OF THE PERIOD. THIS WILL LIMIT INSTABILITY DURING THE REST OF THE AFTERNOON AND EVENING. SO THE CHANCE OF THUNDERSTORMS OCCURRING AT ANY OF THE TERMINALS LOOKS LOW AT THIS TIME. HAVE INCLUDED A PERIOD OF SHOWERS IN THE CINCINNATI AND COLUMBUS TERMINALS. REMAINING MVFR VISIBILITIES SHOULD IMPROVE OVER THE NEXT FEW HOURS BUT THEN WILL LIKELY REDEVELOP OVERNIGHT. VISIBILITY WILL IMPROVE TO VFR AGAIN LATE IN THE TAF PERIOD. THE CHANCE OF SHOWERS AND THUNDERSTORMS IS FORECAST TO BE LOW THROUGH 18Z FRIDAY BUT THEN INCREASE AFTER THE END OF THE TAF PERIOD.
