AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 350 PM EDT FRI MAY 25 2001 UPPER LOW WAS CENTERED OVER NORTHERN INDIANA THIS AFTERNOON...WHILE MAIN SURFACE LOW ASSOCIATED WITH THIS FEATURE WAS LOCATED OVER WISCONSIN...WITH MOST PRONOUNCED SURFACE TROUGHING EXTENDING FROM THIS FEATURE EAST ACROSS SOUTHERN MI. EAST OF THE UPPER LOW...A SHORTWAVE WAS ROTATING NW ACROSS NW LOWER MICHIGAN...ENHANCING SHOWER/THUNDERSTORM COVERAGE THERE...WHILE ANOTHER SHORTWAVE WAS APPROACHING NW OH AND HEADING NORTH. FINALLY...A LONG BAND OF ENHANCED MOISTURE/PRECIP COVERAGE...UNDER BAND OF STRONGEST WINDS AT 850-250 MB...WRAPPED AROUND THE PERIPHERY OF THE UPPER LOW FROM THE SE US ACROSS LAKE HURON. FORECAST CONCERNS CENTER TIMING OF FEATURES ROTATING THROUGH PARENT LOW AND ASSOCIATED POPS THROUGH MEMORIAL DAY. NW SHORTWAVE AND ASSOCIATED THUNDERSTORMS WILL EXIT NORTHEAST COUNTIES DURING THE NEXT FEW HOURS...BUT PER 12Z MODELS CENTER OF UPPER LOW WILL LIFT N...WHILE NW OH SHORTWAVE WILL PUSH NORTH AND INTO EASTERN COUNTIES OF N LOWER MICHIGAN AROUND MIDNIGHT. SHOWERS/THUNDERSTORMS ARE WIDESPREAD WITH THESE UPSTREAM FEATURES... SO NUMEROUS SHOWERS AND SCATTERED THUNDERSTORMS WILL BE IN FORECAST FOR THE WEST AND THE EAST THROUGH THIS EVENING. PER UPSTREAM RADAR TRENDS AND FORECAST TRACKS OF UPSTREAM FEATURES...PRECIP COVERAGE IN CENTRAL COUNTIES FROM HTL THROUGH GLR TO CHEBOYGAN MAY BE SCATTERED THROUGH THE EVENING...AND WILL MAKE FINAL DECISION AT ISSUANCE TIME. MEANWHILE...AS UPPER LOW LIFTS NORTH...12Z MODELS SUGGEST THAT AS UPPER LOW LIFTS NORTH TONIGHT...AREA OF MEAN 850-500 MB RELATIVE HUMIDITY GREATER THAT 70 PERCENT...NOW ASSOCIATED WITH UPSTREAM THUNDERSTORMS...WILL PUSH INTO AT LEAST SW COUNTIES AND WILL KEEP NUMEROUS SHOWERS GOING THERE OVERNIGHT. FINALLY...PLUME OF DEEP MOISTURE STREAMING NW ACROSS LAKE HURON WILL SPREAD INTO EASTERN UPPER MICHIGAN THIS EVENING...FARTHER WEST THAN INDICATED BY 12 MODELS...AS OH SHORTWAVE PUSHES NORTH...SO NUMEROUS SHOWERS AND SCATTERED THUNDERSTORMS ARE IN ORDER THERE THIS EVENING. THEN...AS UPPER LOW CIRCULATION SPREADS OUT OVERNIGHT...AXIS OF DEEP LAYER STRONG WINDS WILL SHIFT N/E OF THE EASTERN UP...AND PRECIP COVERAGE WILL DIMINISH OR DISSIPATE OVERNIGHT. LATEST SURFACE OBSERVATIONS SUGGEST THAT A CLOSED SURFACE LOW MAY BE DEVELOPING OVER SW MI THIS AFTERNOON...IF THIS FEATURE HOLDS TOGETHER AND PUSHES UP INTO SOUTHERN COUNTIES THIS EVENING...LOW LEVEL WIND SHEAR WILL BE ENHANCED...AND EVENING SHIFT WILL NEED TO MONITOR THUNDERSTORMS CLOSE TO LOW FOR LOW LEVEL ROTATION. SATURDAY...EXCEPT FOR LINGERING SHOWERS (AND ISOLATED THUNDERSTORMS) CLOSEST TO UPPER LOW IN THE W/SW...DAY WILL START OFF WITH AREAS OF FOG BUT NOT MUCH PRECIP. THEN...AS NORTHERN/WESTERN WILL BE IN A SIMILAR REGIME AS N IN/W OH/S MI...WITH 500 MB TEMPS FORECAST TO FALL A DEGREE OR TWO FROM THOSE OF THIS MORNING (-24C)...SO SHOWERS AND THUNDERSTORMS WILL BECOME WIDESPREAD...WITH AT LEAST LIKELY POPS IN ORDER...SATURDAY AFTERNOON. IN THE EAST...ANOTHER SHORTWAVE IS FORECAST TO ROTATE THROUGH PARENT LOW FROM SE MI TO NE MI 18Z-0Z...AND THIS FEATURE WILL ENHANCE SHOWERS/THUNDERSTORMS THERE...SO WILL FORECAST LIKELY POPS EVEN IN THE EAST SATURDAY AFTERNOON. SATURDAY NIGHT THROUGH SUNDAY NIGHT...AND PERHAPS INTO MEMORIAL DAY...MODELS AGREE THAT ANOTHER SHOT OF DEEP MOISTURE/DEEP LAYER QG FORCING WILL PUSH INTO THE REGION FROM THE S/SW LATE SATURDAY OR SATURDAY NIGHT. ALSO...MODELS NOW ADVERTISE THAT SURFACE LOW OVER WISCONSIN WILL INTENSIFY AND WILL ROTATE INTO S/CENTRAL MI BY SATURDAY EVENING...ENHANCING LOW LEVEL CONVERGENCE. THEN...THE 12Z AVN/UKMET FORECASTS SUGGEST THAT SURFACE LOW AND DEEP MOISTURE WILL REMAIN OVER THE REGION...JUSTIFYING AT LEAST LIKELY POPS WITH A CHANCE OF THUNDERSTORMS...THROUGH THE PERIOD. .EXTENDED...EXCEPT FOR CANADIAN MODEL...MEDIUM RANGE MODELS GRADUALLY PUSH THE SURFACE/UPPER LOW EAST OF THE REGION MEMORIAL DAY. HOWEVER...ENOUGH CYCLONIC FLOW/MOISTURE WILL PERSIST TO JUSTIFY A CONTINUED MENTION OF SHOWERS (WITH PM THUNDERSTORMS POSSIBLE). IN FACT...6Z AVN SUGGESTS THAT THE DAY WILL START WITH DEEP MOISTURE/WIDESPREAD PRECIP...ESPECIALLY ACROSS NORTHERN LOWER MICHIGAN. TUESDAY FORECAST IS TRICKY. CANADIAN MODEL HOLDS THE SFC/UPPER LOWS OVER THE REGION LONGEST...BUT TREND IS MORE PROGRESSIVE THAN PREVIOUS RUNS. MEANWHILE...ALL MODELS SUGGEST THAT A COLD FRONT WILL PUSH INTO OR PASS THROUGH THE FORECAST AREA AT SOME POINT DURING TUESDAY. 0Z MRF/6Z AVN MOST AGGRESSIVE WITH STRENGTH OF COLD FROPA...ENOUGH SO TO CONVINCE ME TO LOWER TEMPS JUST A BIT TUE-WED FROM PREVIOUS FORECAST...BUT FRONT WILL PUSH THROUGH RAIN FREE AS IT ENCOUNTERS AREA OF DRYING/SUBSIDENCE IN WAKE OF DEPARTING UPPER LOW. 0Z UKMET EVEN SUGGESTS THAT SURFACE BOUNDARY WILL STALL OVER THE SOUTH...WITH AN ENHANCED CHANCE FOR (ESPECIALLY PM) SHOWERS AND THUNDERSTORMS THERE...BUT SURFACE BOUNDARY SHOULD KEEP PUSHING SOUTH GIVEN NW STEERING FLOW. FOR NOW...WILL CONTINUE CURRENT DRY FORECASTS FOR TUESDAY. THEN...MRF AGAIN SUGGESTS THAT RIDGING/WARMING TREND WILL DOMINATE THE WED-FRIDAY TIME PERIOD. EUROPEAN MODEL SUGGESTS A CHANCE FOR SHOWERS/THUNDERSTORMS THURSDAY AS A SHORTWAVE AND ASSOCIATED SURFACE LOW/COLD FRONT APPROACH THE REGION...THE SAME SYSTEM THAT WAS FORECAST TO PUSH THROUGH THE REGION WEDNESDAY IN THE PREVIOUS RUN. LATEST RUN OF THE EUROPEAN IS CLOSER TO MRF...SUGGESTING A DEEPER TOUGH TO THE EAST AND STRONGER RIDGING OVER THE FORECAST AREA...RESULTING IN A SLOWER/FARTHER NORTH TRACK/WEAKENING TREND FOR APPROACHING FOR SHORTWAVES. STILL FEEL THAT EUROPEAN IS PUSHING SHORTWAVE/COLD FRONT TOO FAR SOUTH THURSDAY...SO WILL FAVOR MRF SOLUTION. BY FRIDAY...MRF SUGGESTS THAT SURFACE LOW OVER HUDSON BAY WILL PUSH A COLD FRONT TOWARD SOUTHERN CANADA...AND A SERIES OF WEAK SHORTWAVES WILL BEGIN TO BREAK DOWN THE RIDGE OVER THE REGION...BUT LACK OF MOISTURE/CLEAR FOCUS FOR CONVECTION JUSTIFIES A DRY FORECAST. .APX...NONE.
