UPDATED TO REMOVE MORNING PORTION AND LOWER MAX TEMPS IN CENTRAL HIGHLANDS. && .SHORT TERM (TODAY THRU FRIDAY)... QUESTION TDA IS HOW FAR MORN OUTFLOW BOUNDARIES PROGRESS TO THE SSE WHICH WL DETERMINE FOCUS FOR MIDDAY NEW CONVECTION. CERTAINTLY LOOKS AS IF A PART OF NWRN CWA WL BE N OF THE BNDRY AND MAY BE SPARED FM HVY RA AND SVR THREAT ASSUMING ONGOING STRONGER ACTIVITY OVR NRN IN AND LWR MI CONTS TO WKN AS IT MOVS INTO NWRN PART OF OUR CWA. WL HV TO WATCH TO ZONE ISSUE TIME TO DECIDE IF FLOOD WATCH MAY NEED ADJUSTING TO ELIMINATE ANY OF THESE COS...BUT PROB WL LV AS IS FOR CONSISTENCY PURPOSES. OTRW...WITH PW/S CLOSE TO TWO INCHES AND GND MSTR HI IN MANY COS THINK FLOOD WATCH IS GUD IDEA FOR MUCH OF AREA. CDFNT MOVS SE OF CWA THIS EVE SO FAR NW SHUD BE DRY SO POPS THERE NEED TO BE ADJUSTED DOWN ALG WITH PUTTING SOME TIMING IN FOR RMNG PRECIP ENDING NW TO SE TNGT. HI PRES AND DRIER AIR BLD IN FRI FOR DRY WX AND NOTICEABLY LESS HUMID CONDS. && .LONG TERM (FRIDAY NIGHT THROUGH WEDNESDAY)... HIGH PRESSURE BUILDS SOUTHEAST ACROSS THE AREA FRIDAY NIGHT AND PUSHES MOISTURE SOUTHEAST OF THE AREA. THE HIGH DOMINATES THE WEATHER THROUGH SUNDAY BUT A RETURN BACK TO TEMPERATURES IN THE MIDDLE AND UPPER 80S IS EXPECTED AS RETURN SOUTHERLY FLOW DEVELOPS ON SUNDAY. WEAK COLD FRONT SHIFTS SOUTHEAST OVER THE AREA SUNDAY NIGHT. MOISTURE WITH THE FRONT WILL BE LIMITED. HOWEVER...WILL KEEP MENTION OF CHANCE OF SHOWERS AND THUNDERSTORMS SUNDAY NIGHT WITH THE FRONT. ANOTHER DIRTY HIGH PRESSURE SYSTEM WILL BUILD SOUTHEAST ACROSS THE AREA MONDAY NIGHT AND TUESDAY. THE HIGH WILL BRING WITH IT SOME MOISTURE TO WORK WITH AND DAY TIME INSTABILITY COULD CAUSE A CHANCE FOR LATE MORNING AND AFTERNOON SHOWERS AND THUNDERSTORMS TO DEVELOP. THEN MUCH DRIER AIR WILL WORK INTO THE AREA WEDNESDAY WITH THE HIGH PRESSURE SYSTEM AS IT MOVES SOUTH OVER THE REGION. SO WILL BRING AN END TO THE SHOWER AND THUNDERSTORM THREAT. STAYED FAIRLY CLOSE TO MEX GUIDANCE TEMPERATURES THROUGH THE PERIOD. && .AVIATION(06Z-06Z)... LEADING CONVECTION OVER FAR NRN INDIANA/SRN MI CONTINUES TO WEAKEN AS THE ASSOCIATED COLD POOL OUTRUNS THE CONVECTION AND IT MOVES INTO DRIER AIR OVER OHIO. THE FRONT OVER CENTRAL LOWER MI WL MOVE TO JUST N OF TOL BY 12Z...THEN SLOW DOWN AS THE WAVE OVER MISSOURI MOVES ALONG THE FRONT. THE FRONT WILL BE THE MAIN FOCUS FOR CONVECTION ON THURSDAY. BY 18Z...THE FRONT SHOULD BE THRU TOL/CLE/ERI. THIS MAY LIMIT THE STRENGTH OF CONVECTION FOR THESE SITES. HOWEVER...STRONGER CONVECTION IS VERY POSSIBLE FOR THE SOUTHERN SITES BY AFTERNOON. DID NOT WANT TO PIN DOWN DETAILS ON THE CONVECTION...BUT THE GENERAL THINKING IS THAT THERE WILL BE NUMEROUS/WIDESPREAD STORMS THROUGHOUT THE AFTERNOON ESPECIALLY FOR THE SOUTHERN 1/2 OF THE FORECAST AREA WHERE THE BEST INSTABILITY WILL BE. SOME OF THE STORMS MAY BE STRONG BY AFTERNOON WITH A SFC DELTA THETA-E OF -35C AND DCAPE OF 1500 J/KG. THIS WILL MAKE SEVERE WIND GUSTS OF 50 KT OR GREATER THAN MAIN CONCERN WITH ANY SEVERE STORM. OTHER THAN THE STORMS....MAY SEE A FEW SITES TEMPORARILY DROP TO MVFR VSBYS BY 10Z. HOWEVER...SLIGHTLY STRONGER WIND AND BETTER MIXING MAY SHOULD PRECLUDE VSBYS DROPPING TO IFR. && .CLE WATCHES/WARNINGS/ADVISORIES... .OH...FLASH FLOOD WATCH 10 AM THU THRU 4 AM FRI. .PA...FLASH FLOOD WATCH 10 AM THU THRU 4 AM FRI. && SHORT TERM...ADAMS LONG TERM...LOMBARDY AVIATION...MRD
