NWS Wilmington, OH wrote its last area forecast discussion before the first event at Sep 12, 9:49 AM EST, 2 hours 36 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 1049 AM EDT THU SEP 12 2013 .SYNOPSIS... A COLD FRONT WILL BRING THE LIKELIHOOD FOR SHOWERS AND THUNDERSTORMS TODAY. AFTER THE FRONT MOVES SOUTH TONIGHT...HIGH PRESSURE AND A COOL...DRY AIRMASS WILL FOLLOW FOR FRIDAY AND SATURDAY. A WEAK COLD FRONT WITH LIMITED MOISTURE WILL CROSS THE AREA ON SUNDAY. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... PRIMARY LINE OF CONVECTION IS MOVING THROUGH THE REGION ATTM. EXPECT THIS TO GRADUALLY WORK THROUGH THE SRN HALF OF THE REGION DURING THE LATE MRNG AND AFTN HOURS. WHETHER YOU WANT TO CALL IT A SECONDARY FRONT/A POST FRONTAL TROF OR THE PRIMARY FRONT...SOME OF THE MESO-SCALE MODELS ARE SUGGESTING THAT SOME SCT SHRA MIGHT FORM ON IT AS IT MOVES THROUGH THIS AFTN. SO FOR NOW HAVE A 20 POP DEVELOPING ACROSS THE N AND THEN WORKING S AS THIS FEATURE DROPS DOWN. THERE IS STILL A LOW CHANCE THAT SOME THUNDERSTORMS MAY REACH SEVERE LIMITS IN THE MODERATE INSTABILITY AND MARGINAL SHEAR ALONG AND S OF THE OHIO RIVER. TEMPERATURES WILL BE VARIABLE AS THEY WARM AHEAD OF THE CURRENT LINE...THEN COOL AS THE CONVECTION DROPS IN...BEFORE REBOUNDING AGAIN POST PCPN. && .SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY/... SHOWERS AND THUNDERSTORMS ALONG THE FRONT WILL BE EXITING SOUTH EARLY THIS EVENING. ANOTHER ROUND OF LIGHT SHOWERS MAY OCCUR BEHIND THE FRONT LATE TONIGHT AS A SHORT WAVE CONTAINING SCANT MOISTURE TRAVELS ALONG A NORTHWESTERLY UPPER FLOW. LOWS IN THE 50S WILL BE MUCH COOLER THAN LOWS OF THE LAST FEW NIGHTS. FOR FRIDAY THROUGH SATURDAY...HIGH PRESSURE WORKING IN FROM THE NORTHWEST WILL PROVIDE A PERIOD OF DRY WEATHER. MOSTLY SUNNY SKIES ARE EXPECTED DURING THE DAY WITH CLEAR SKIES AT NIGHT. HIGHS WILL ONLY BE IN THE 60S ON FRIDAY IN A REGIME OF COLD ADVECTION. AFTER CHILLY OVERNIGHT LOWS IN THE 40S FRIDAY NIGHT...READINGS SHOULD REACH AROUND 70 BY LATE SATURDAY AFTERNOON. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... THE AIR MASS WITH HIGH PRESSURE WILL BE QUITE DRY...LEADING TO SOME QUESTIONS IN THE FORECAST REGARDING A COLD FRONT MOVING INTO THE AREA LATE SUNDAY INTO MONDAY. THE 12Z GEM AND GFS MODELS BOTH INDICATED THAT ONLY AN INCREASE IN MID TO HIGH LEVEL RH WOULD OCCUR...WITH LIMITED LOW-LEVEL MOISTURE AND NO QPF RESPONSE. 00Z AND 12Z ECMWF RUNS BOTH INDICATE A LITTLE MORE MOISTURE...WITH AN AIR MASS CAPABLE OF SUPPORTING ISOLATED SHOWERS AND STORMS. ALTHOUGH THE TREND SEEMED TO BE IN A DRIER DIRECTION OVERALL...AND IT WOULD NOT BE SURPRISING IF FUTURE FORECASTS END UP DRY...SLIGHT CHANCE POPS WERE MAINTAINED FOR THIS PERIOD. THE FRONT WILL MOVE SOUTHEAST...MAKING PROGRESS INTO THE CAROLINAS BY MONDAY NIGHT. ITS WESTWARD EXTENT APPEARS LIKELY TO STALL ON A NW-TO-SE TRAJECTORY FROM THE NORTHERN PLAINS INTO THE LOWER OHIO VALLEY. WITH BUILDING RIDGING OVER THE MID-SECTION OF THE COUNTRY AND SURFACE HIGH PRESSURE AGAIN OVER THE GREAT LAKES AND UPPER OHIO VALLEY...EVENTUALLY THE HIGHER THETA-E AIR WILL SHIFT EASTWARD. THIS WILL LEAD TO A GRADUAL RISE IN TEMPS THROUGH THE WEEK...WITH WEDNESDAY APPEARING CAPABLE TEMPS IN THE 80S (MAYBE EVEN MID TO UPPER 80S IN THE SW CWA). PRECIPITATION CHANCES WILL ALSO BEGIN TO INCREASE ON (AND ESPECIALLY AFTER) WEDNESDAY...BUT TOO NEAR THE END OF THE FORECAST PERIOD TO TRY AND DRAW ANY SPECIFICS. && .AVIATION /15Z THURSDAY THROUGH MONDAY/... MID LEVEL TROF WILL DIG SE ACRS THE GREAT LAKES WITH INITIAL SFC COLD FRONT SWEEPING SE THRU THE TAF SITES THIS MORNING. FOG HAS DEVELOPED IN THE MOIST AIRMASS IN ADVANCE OF THE COLD FRONT. THESE VSBY RESTRICTIONS WILL IMPROVE AS CLOUDS INCREASE EARLY. COLD FRONT WITH WIDESPREAD SHOWERS AND THUNDERSTORMS ALONG AND AHEAD OF IT WILL CROSS THE TAF SITES DURG THE MORNING. HAVE PREVAILING PRECIPITATION DURG THE 3 OR 4 HOUR WINDOW WHEN THE BEST THREAT FOR THUNDERSTORMS LOOKS TO OCCUR. GENERALLY EXPECT CIGS TO REMAIN IN THE VFR CATEGORY WITH MVFR VSBYS. NORTHWEST WINDS WILL USHER MUCH COLDER AIR BEHIND THE FRONT AND COLD POOL STRATOCU CLOUDS WILL BE OBSERVED IN THE VFR CATEGORY. A FEW SHOWERS WILL BE POSSIBLE THIS EVENING ACRS CENTRAL OHIO. HAVE LIMITED MENTION TO VCSH AT KCMH/KLCK. OTHERWISE...EXPECT IMPROVING CONDITIONS WITH CLOUDS DIMINISHING AS HIGH PRESSURE BUILDS INTO THE GREAT LAKES.
