NWS Cleveland, OH wrote its last area forecast discussion before the first event at Jul 24, 2:15 PM EST, 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CLEVELAND OH 315 PM EDT TUE JUL 24 2007 .SYNOPSIS... A WEAK RIDGE FROM THE ATLANTIC COAST INTO THE AREA WILL GRADUALLY WEAKEN TODAY. AN UPPER LEVEL LOW PRESSURE OVER THE UPPER OHIO VALLEY WILL DRIFT SLOWLY NORTHWEST TO LOWER MICHIGAN EARLY THURSDAY THEN BEGIN TO MOVE NORTHEAST. A COLD FRONT WILL MOVE THROUGH EARLY ON SATURDAY. && .NEAR TERM /THROUGH WEDNESDAY/... UPPER LOW WEST OF WHEELING THIS MORN AND PROGGED TO DRIFT NNW BY ALL MODELS. SOME LAKE ENHANCED SHOWERS HAVE DIMINISHED. CONVECTION WHICH ACTUALLY DEVELOPED LAST NIGHT NOW FOCUSED MAINLY OVER HIGHER HILLS OF THE CENTRAL APPALACHIANS. NE OH/NW PA HAS HAD MORE SUNSHINE SO FAR TODAY AND WILL REACH THE CONVECTIVE TEMP (WHICH IS ABOUT 75F ON 12Z SOUNDING) QUICKER THAN OTHER AREAS. SPIRAL BAND OF LAKE ENHANCED MOISTURE JUST WEST OF CLE SOUTH TOWARD MFD AND MARION COULD ALSO BUBBLE UP QUICKER THAN OTHER AREAS ASSUMING WE CAN GET ENOUGH WARMING TO GET AT LEAST CLOSE TO THE CONVECTIVE TEMP. IT IS ANYONES BET WHERE ELSE THE INDIVIDUAL SHOWERS/STORMS MAY POP UP WITH THE UPPER LOW ESSENTIALLY DIRFTING OVERHREAD. SINCE SHOWERS/STORMS DEVELOPED LAST NIGHT NEAR AND UNDER THE UPPER LOW I HAVE TO ASSUME THAT IT MAY OCCUR AGAIN TONIGHT SO WILL HAVE TO KEEP AT LEAST A LOW POP CHANCE OF SHOWERS LATER TNGT INTO WED MORN. FLOW IS GENERALLY SOUTHEAST THROUGH A DEEP LAYER OVER THE ENTIRE FCST AREA ON WEDNESDAY SO NOT AS MUCH SPIRAL BAND ISSUES TO DEAL WITH. COULD SEE A MORE ACTIVE LAKE BREEZE FRONT WEDNESDAY AS SE FLOW WILL INTERACT WITH ONSHORE BREEZE OTHERWISE WILL FCST SCT SHOWERS/STORMS. HAIL NOT OUT OF THE QUESTION WITH COLD AIR ALOFT BUT IN GENERAL DO NOT ANTICIPATE SEVERE WEATHER. TEMPS MAY ACTUALLY BE A BIT COOLER TNGT COMPARED TO LAST NIGHT WHEN MOST AREAS WERE CLOUDY. SOME OF THE DIURNAL CUMULUS WILL DECREASE THIS EVENING. GFS MIN TEMP GUIDANCE SEEMS A CETEGORY TOO COOL THOUGH...GENERALLY UPPER 50S FOR MIN TEMPS. GFS MAX TEMP GUIDANCE SEEMS TOO WARM WEDNESDAY AS CLOUDS SHOULD DEVELOP QUICKLY. MODEL SOUNDING PUT CONVECTIVE TEMP STILL IN THE MID 70S TOMORROW. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/... UPPER LOW SHOULD CONTINUE TO DRIFT TO THE NNW. THE NAM/WRF AND GFS DEVELOP AN AREA OF STRONG UPWARD MOTION OVER THE MIDWEST ON THURSDAY AND ROTATE IT INTO NORTHERN OHIO THURSDAY NIGHT. LITTLE CONFIDENCE OF THIS FEATURE AS THERE MAY BE CONVECTIVE FEEDBACK IN THE MODELS. THERE MAY BE A SOMEHWAT BETTER CHANCE FOR CONVECTION THURSDAY WITH A SSW FLOW COMPARED TO A SE FLOW (DOWNSLOPE) BUT WOULD LIKE TO SEE MORE RUN TO RUN CONTINUITY BEFORE GOING WITH SIGNIFICANTLY HIGHER POP FOR THURSDAY/THUR NGT...OTHERWISE MORE OF THE SAME. SOUTHWEST FLOW ON FRIDAY AND SOME OF THE HEAT FROM THE PLAINS STATES WILL TRY TO NOSE EASTWARD BUT CERTAINLY WE WILL NOT SEE THE BRUNDT OF THE HOT AIR...PROBABLY LWR/MID 80S ASSUMING THAT WE GET SOME SUNSHINE. STILL OF COURSE A CHANCE OF SHOWERS/STORMS AND OF COURSE MOST AREAS CAN REALLY USE THE RAIN SO WE WILL KEEP FINGERS CROSSED. CONVECTIVE TEMP ON MODEL SOUNDINGS STILL PROGGED IN THE MID TO UPPER 70S THURSDAY SO DO NOT ANTICIPATE MAX TEMPS TO BE MUCH MORE THAN A CATEGORY ABOVE THAT SO WILL CONTINUE TO FCST MAX TEMPS A LITTLE BELOW GFS GUIDANCE. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... MODELS TRY TO DEFLECT UPPER LOW BACK TO THE SOUTHEAST...TOWARD LAKE ERIE...AS TROUGH AMPLIFIES LATE IN THE WEEK BUT IN ALL LIKELIHOOD THE UPPER LOW WILL EJECT AS IT EVENTUALLY GETS CAUGHT UP IN THE JET AND SHOULD LIFT OUT ON FRIDAY. NEXT SHORT WAVE DROPPING SOUTHEAST ASSOCD WITH COLD FRONT. GFS HINTS AT NEW UPPER LOW AT H5 BY SATURDAY OVER THE LOWER LAKES BUT HAVE VERY LITTLE CONFIDENCE THAT THIS FEATURE WILL REALLY EXIST...LOOKS TO BE INDUCED BY CONVECTIVE FEEDBACK AND PERHAPS IS ALSO A REFLECTION OF OLD UPPER LOW WHICH THE GFS DOES NOT EJECT FAST ENOUGH. ECMWF SIMPLY SHOWS A PROGRESSIVE TROUGH ON SATURDAY WHICH SEEMS LIKE A BETTER SOLUTION. NONETHELESS...THERE HAVE BEEN CONSISTENT SIGNS ON ALL MODELS THAT THE COLD FRONT WILL BE SLOW TO PUSH SOUTH AND WILL BE SHALLOW AT FIRST WHICH IS TYPICAL FOR THIS TIME OF YEAR SO STILL A CHANCE OF SHOWERS/STORMS ON SATURDAY. ANOTHER IN AN AMAZINGINGLY CONSISTENT STRING OF CANADIAN HIGH PRESSURE SYSTEMS PROGGED TO SINK SOUTH ACROSS THE GREAT LAKES STARTING SAT NGT INTO NEXT WEEK. LOTS OF RIDGING ALOFT SO IT MAY NOT BE AS COOL AS RECENT HIGHS BUT I WOULD AT LEAST EXPECT TEMPS TO RETURN TO NEAR NORMAL OR SLIGHTLY BELOW NORMAL FOR A COUPLE OF DAYS BEFORE WARMING BY TUES/WED NEXT WEEK. DEWPOINTS AGAIN SHOULD DRY OUT AND WITH DECENT RADIATING CONDITIONS SHOULD SEE NIGHT TIME TEMPS RELATIVELY COOL/COMFORTABLE. && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... MAINLY VFR CONDITIONS SHOULD PREVAIL THRU 18Z WED. UPPER LOW OVER NE OH SHOULD ACT TO DESTABILIZE AIRMASS SOME BUT LOW LEVELS RELATIVELY DRY SO GETTING A LOT OF CONVECTION TO DEVELOP THIS AFTERNOON OR MIDDAY ON WED WILL BE TOUGH. THINK THAT SHRA AND ISOLATED TSRA WL BE WIDELY SCT ENOUGH SO THAT TAF SITES WILL TEND TO BE MISSED. BEST CHANCE FOR TSRA THIS AFTERNOON WOULD APPEAR TO BE AROUND YNG AND FDY WHERE BETTER BREAKS IN CLOUDS WILL ALLOW FOR BEST HEATING AND INSTABILITY TO DEVELOP. IF ANYTHING APPEARS IMMINENT AT TAF RELEASE TIME WL ADJUST FIRST FEW HOURS WITH A TEMPO GROUP AS NEEDED. PLAN FOR SOME FOG TO DEVELOP TONIGHT FOR THE INLAND LOCATIONS BUT WL LIMIT TO MVFR FOR NOW AS MID CLOUDS EXPECTED TO HANG AROUND THRU THE NIGHT. THREAT FOR SCT SHRA AND TSRA WL CONTINUE THRU SAT AS UPR LOW HANGS NEAR AREA THEN NEXT CDFNT MOVS SE THRU THE AREA SAT. MVFR FOG PROB WL OCCUR IN THE FAVORED AREAS EACH NITE...OTRW SHUD SEE VFR CONDITIONS PREVAIL OUTSIDE OF HEAVIER CONVECTIVE PRECIP AREAS THROUGH THE PERIOD. && .MARINE... ON THE WHOLE...WINDS ON THE LAKE WILL BE LIGHT AND VARIABLE THROUGH THE MIDDLE OF THE WEEK AS THE SURFACE PRESSURE GRADIENT WILL BE NEARLY NON-EXISTENT. TOWARD THE END OF THE WEEK...WILL SEE WINDS TAKE ON A MORE SOUTHERLY COMPONENT AHEAD OF AN APPROACHING COLD FRONT. FROPA FORECAST TO OCCUR SOMETIME SATURDAY...POST-FRONTAL PUSH OF COOL AIR DOESNT LOOK TO BE TOO SIGNIFICANT SO AM EXPECTING ONLY A WIND SHIFT OUT OF THE NORTH AND WINDS BETWEEN 10-20KTS BEHIND THE FRONT. LIGHT GRADIENT SETS UP AGAIN ON SUNDAY WITH WINDS 10KTS OR LESS OUT OF THE NORTHEAST. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...NONE. PA...NONE.
