AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 438 PM EDT TUE AUG 28 2007 .DISCUSSION...COLD FRONT CURRENTLY EXTENDS FROM WRN UPPER MICHIGAN THRU NRN WISCONSIN INTO SE MINNESOTA AND NE NEBRASKA. LINE OF STRONG/SVR CONVECTION CONTINUES TO FIRE ALONG THIS BOUNDARY... FEEDING OFF A PRONOUNCED RIDGE OF HIGH 850 MB THETA E AIR...CAPES APPROACHING 3500 J/KG AND A FAIRLY VIGOROUS SHORT WAVE RIDING ALONG THE FRONT. LATEST MODEL RUN SEEMS TO HAVE A BETTER HANDLE ON THE CURRENT SITUATION AS COMPARED TO PREVIOUS RUNS. BUILDING CAP (WARMING ALOFT) AND LACK OF FOCUS HAVE BEEN SUCCESSFUL IN PRECLUDING ANY CONVECTIVE DEVELOPMENT ACROSS OUR CWA THIS AFTERNOON. HOWEVER... THE BREAK IN THE ACTION WILL BE SHORT-LIVED AS THE UPSTREAM FRONT... SHORT WAVE AND ENHANCED MOISTURE SHIFT EASTWARD INTO ERN UPR AND NRN LWR MICHIGAN LATER THIS EVENING AND OVERNIGHT. TONIGHT...EARLY EVENING SHOULD BE MOSTLY DRY...WARM AND HUMID AS CAP REMAINS IN TACT. CAP WILL BE WEAKEST ACROSS NRN AND WRN SECTIONS OF THE CWA THIS EVENING CLOSER TO THE APPROACHING FRONT...SHORT WAVE AND THETA E RIDGE AXIS. WILL LEAVE IN A CHANCE OF SHRA/TSRA FOR THESE LOCATIONS DURING THE EVENING...AND THEN SPREAD THE CHANCE OF CONVECTION INTO THE REST OF THE CWA OVERNIGHT AS THE FRONT MOVES INTO NRN LWR MICHIGAN. BETTER ORGANIZED CONVECTION ALONG THE FRONT AND IN CONJUNCTION WITH THE SHORT WAVE WILL FINALLY REACH NRN SECTIONS OF OUR CWA PAST TIME OF PEAK DIURNALLY ENHANCED INSTABILITY. CERTAINLY SB INSTABILITY WILL REMAIN IN PLACE TO MAINTAIN THUNDER IN THE FORECAST. HOWEVER...CHANCE OF SVR IS SLIGHT...AND MAINLY CONFINED TO ERN UPR MICHIGAN WHERE FRONT MAY ARRIVE IN TIME TO BENEFIT FROM THE LAST VESTIGES OF DAYTIME INSTABILITY. LOW TEMPS TONIGHT WILL ONLY COOL INTO THE 60S && REMAINDER OF THE FORECAST...STILL A CHANCE FOR SHOWERS AND THUNDERSTORMS ON WEDNESDAY...OTHERWISE THE WEATHER LOOKS ON THE DRY SIDE FOR A FEW DAYS AS HIGH PRESSURE TAKES OVER. WEAK TROUGH AND ASSOCIATED COLD FRONT IS SHOWN TO MOVE THROUGH THE REGION LABOR DAY THEN STALL OUT TO OUR SOUTH WITH A WARM FRONT IN THE VICINITY ON TUESDAY. THE MAIN FORECAST CONCERNS WILL REVOLVE AROUND POPS WEDNESDAY...MONDAY AND TUESDAY. WEDNESDAY...THE SURFACE COLD FRONT IS EXPECTED TO BE EXITING SOUTHEAST ZONES AROUND DAYBREAK. HOWEVER...SURFACE WAVE ALONG THE FRONT WILL LIKELY HOLD MOISTURE ACROSS THE REGION FOR MUCH OF THE DAY (MEAN 1000-500 MB RH 70 TO 90 PERCENT IN THE MORNING AND 50 TO 70 PERCENT IN THE AFTERNOON). INSTABILITY LOOKS LIMITED DUE TO ABUNDANT CLOUD COVER AND WEAKENING LOW LEVEL WIND FIELDS BEHIND THE FRONT SO SEVERE POTENTIAL APPEARS TO BE NEGLIGIBLE. SO WILL HAVE SLIGHT CHANCE POPS IN THE MORNING ACROSS EASTERN UPPER AND CHANCE POPS ACROSS ALL NORTHERN LOWER ZONES IN THE AFTERNOON (FOR SHOWERS AND SLIGHT CHANCE OF THUNDERSTORMS). HIGHS WILL BE A BIT TRICKY WITH THE TIMING OF CONVECTION BUT WILL GO WITH A RANGE OF THE LOWER 70S NORTH TO THE LOWER 80S SOUTH. WEDNESDAY NIGHT INTO THURSDAY NIGHT...SURFACE HIGH PRESSURE BUILDS INTO THE REGION LEADING TO SOMEWHAT COOLER (MAINLY AT NIGHT) AND LESS HUMID CONDITIONS. MODEL SOUNDINGS/CROSS SECTIONS INDICATE THAT IT WILL BE FAIRLY DRY THROUGH THE COLUMN (MEAN 1000-500 MB RH 30 TO 50 PERCENT) LEADING TO MOSTLY CLEAR CONDITIONS. LOWS WEDNESDAY NIGHT IN THE MIDDLE 40S TO LOWER 50S. 850 MB TEMPERATURES ARE AROUND 10 C THU LEADING TO HIGHS MAINLY IN THE MIDDLE 70S. LOWS THURSDAY NIGHT A BIT CHILLY WITH LOWS IN THE UPPER 30S AND 40S. FRIDAY THROUGH SUNDAY...HEIGHTS ARE SLOWLY ON THE RISE WITH SURFACE HIGH REMAINING IN CONTROL LEADING TO CLEAR TO PARTLY CLOUDY AND INCREASINGLY MILD CONDITIONS. 850 MB TEMPERATURES INCREASE BY A DEGREE OR TWO EACH DAY SO HIGHS WILL MODIFY FROM THE LOWER AND MIDDLE 70S ON THURSDAY INTO THE MIDDLE 70S TO THE LOWER 80S SATURDAY INTO THE UPPER 70S TO MIDDLE 80S SUNDAY. SUNDAY NIGHT INTO TUESDAY...LOW PRESSURE WILL MOVE ACROSS CENTRAL CANADA SUNDAY NIGHT AND DRAG A MOISTURE STARVED COLD FRONT ACROSS THE REGION ON MONDAY. THIS WILL LEAD TO LOW CHANCE POPS ACROSS EASTERN UPPER AND SLIGHT CHANCE POPS ACROSS NORTHERN LOWER MONDAY. THE GFS THEN STALLS THE COLD FRONT ACROSS THE REGION AND LIFTS IT NORTHWARD AS A WARM FRONT ON TUESDAY. THIS SCENARIO IS POSSIBLE BUT WILL NOT INSERT POPS AT THIS TIME SINCE ITS SO FAR OUT. HIGHS FOR BOTH MONDAY AND TUESDAY IN THE MIDDLE 70S TO AROUND 80. SULLIVAN && .AVIATION...UPSTREAM COLD FRONT WILL MAKE SLOW PROGRESS EASTWARD INTO NRN MICHIGAN THIS AFTERNOON AND TONIGHT. WARM/MOIST AIR WILL CONTINUE TO RIDE NORTHWARD ALONG AND AHEAD OF THE BOUNDARY...SETTING OFF WAVES OF SHOWERS AND THUNDERSTORMS THRU WEDNESDAY MORNING. VFR VSBYS/CIGS WILL BE THE RULE THRU THE FORECAST PERIOD...BUT SPOTS OF MVFR/IFR ARE EXPECTED IN AND AROUND HEAVIER SHOWERS/THUNDERSTORMS. && .APX WATCHES/WARNINGS/ADVISORIES...NONE. &&
