HIGH PRESSURE WILL BEGIN TO WORK INTO THE AREA THURSDAY AFTERNOON ALLOWING FOR A RETURN TO DRY CONDITIONS THROUGH FRIDAY. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... A COLD FRONT WAS LOCATED ACROSS NORTHERN MI AND IL THIS AFTERNOON. THE FORECAST AREA WAS IN THE WARM SECTOR AHEAD OF THE FRONT AND CONVECTION HAD BEGUN TO DEVELOP AROUND MIDDAY. MODELS FAIRLY SIMILAR IN HANDLING FRONT. TRENDED TOWARD GFS AND ECMWF FOR FORECAST. THE FRONT IS EXPECTED TO DROP INTO THE NORTHWEST PART OF FORECAST AREA LATER THIS EVENING AND MOVE TO LOCATION EXTENDING FROM CENTRAL OH TO SOUTHWESTERN OH TO SOUTHERN INDIANA BY EARLY THU MORNING. BEST CHANCE FOR SEVERE WEATHER WILL BE THROUGH THE EARLY NIGHTTIME HOURS WITH CONVECTION IN ADVANCE OF THE COLD FRONT. DAMAGING WINDS WOULD BE THE MOST LIKELY TYPE OF SEVERE WEATHER. THE INSTABILITY DECREASES THROUGH THE NIGHT WITH THE LOSS OF HEATING. THE BETTER DYNAMICS REMAIN NORTH AND EAST OF THE AREA WITH THE FRONTAL PASSAGE AND THE CHANCE OF PRECIPITATION WITH THE FRONT DECREASES AFTER MIDNIGHT. POPS IN THE LIKELY CATEGORY THIS EVENING IN MANY AREAS DECREASE TO CHANCE CATEGORY AFTER MIDNIGHT. LITTLE CHANGE IN FORECAST LOWS TONIGHT.

AS HIGH SLIDES EAST...SOUTHERLY FLOW COMBINED WITH A WEAK MIDLEVEL IMPULSE MAY BRING A FEW SHOWERS OR THUNDERSTORMS ON SATURDAY AND SATURDAY NIGHT. TRENDED CLOSER TO THE ECMWF AND GFS ENS MEAN FOR EARLY NEXT WEEK WITH FLAT UPPER RIDGE EXTENDING ACROSS MUCH OF THE SOUTHERN CONUS. GFS SEEMS MUCH TOO AMPLIFIED WITH THE RIDGE...AND THE MEX NUMBERS IN THE MID TO UPPER 90S NEXT WEEK ARE UNREALISTIC. USED A BLEND OF BCECMWF AND MEN GUIDANCE WITH HIGHS IN THE UPPER 80S AND POSSIBLY NEAR 90 IN A FEW SPOTS ACROSS THE SOUTH. BOTH ECMWF AND GFS ENS GUIDANCE SUGGEST A WEAK FRONT PUSHING INTO THE REGION TUES AND WEDS WITH AN ATTENDANT THREAT FOR SCATTERED THUNDERSTORMS. && .AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
