AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
344 PM EDT FRI AUG 22 2008

.SYNOPSIS...ISSUED 344 PM...WARM AND MUGGY WILL BE SWEPT ASIDE
SATURDAY AS A COLD FRONT MOVES THRU. SHOWERS AND STORMS ARE POSSIBLE
THRU THIS EVENING...AND AGAIN AS THE FRONT ARRIVES SATURDAY. MUCH
COOLER WEATHER IS ON TAP FOR THE END OF THE WEEKEND.

JZ

&&

.SHORT TERM...ISSUED 344 PM...(TONIGHT)...EARLIER AREA OF SHRA/TSRA
IN SW LOWER MI LARGELY FELL APART AS IT TRIED TO LIFT NE THRU
MIDDAY. MOST OF OUR PRECIP HAS INSTEAD ORIGINATED FROM LAKE MI
COASTAL CONVERGENCE. 850MB WINDS ARE IN THE 35-45KT RANGE...IMPLYING
A LOW-END WIND THREAT FOR A FEW HOURS UNTIL DAYTIME HEATING WANES.
OUTSIDE OF THE LAKE MI COAST...AN OCCASIONAL ISOLATED SHRA FORMS...
BUT IS UNABLE TO SUSTAIN ITSELF LONG. THIS PRECIP IS DIURNALLY
FORCED...AND WILL END THIS EVENING.

FOR THE REST OF THE NIGHT...WE SAW A CONSIDERABLE AMOUNT OF STRATUS
FORM LAST NIGHT UPSTREAM IN WI/IOWA/MN...WHERE THE MID LEVELS HAD
DRIED OUT. WITH A SOUPY LOW LEVEL AIRMASS IN PLACE...DON/T SEE ANY
REASON WHY THAT WON/T HAPPEN LATE TONIGHT. SO AFTER A BRIEF PERIOD
OF PARTIAL CLEARING...EXPECT LOW STRATUS TO FORM IN THE NORTH AND
WEST OVERNIGHT.

THE COLD FRONT WILL REACH CENTRAL UPPER MI BY 12Z. WILL CONTINUE TO
BRING A SMALL CHANCE OF SHRA/TSRA BACK TO EASTERN UPPER MI AFTER
09Z. THE MAIN SHOW FOR US WILL DEFINITELY BE AFTER SUNRISE.

MIN TEMPS WILL BE VERY VERY MILD...HELD UP BY MOIST LOW LEVELS AND
STEADY SOUTH TO SW WINDS. READINGS MAINLY MID 60S TO LOWER 70S.

JZ

&&

.LONG TERM...ISSUED 344 PM...(SATURDAY ONWARD)...MAIN CONCERNS WILL
BE THE FRONTAL PASSAGE AND THE SECOND IMPULSE BEHIND THE FRONT ON
SUNDAY. GFS HAS REMAINED CONSISTENT, WHILE THE ECMWF AND THE NAM
HAVE BACKED OFF FROM THE IDEA YESTERDAY FOR LAKE EFFECT RAIN.

SATURDAY...THE FRONT PASSES THROUGH THE STATE DURING THE DAY. THE
FRONT LOOKS FAIRLY STRONG WITH THE THERMAL PACKING, REINFORCED BY
THE 500 MB WAVE. SO TRIED TO SPLIT THE DAY, TO SHOW THE FRONT
PASSING THROUGH INSTEAD OF HAVING ONE FULL DAY OF RAIN.

SATURDAY NIGHT...THE FRONT LEAVES THE REGION. THE SUBSIDENCE BEHIND
THE FRONT LOOKS PRETTY STRONG AS THE SFC HIGH BUILDS INTO THE
WESTERN GREAT LAKES PRETTY QUICKLY. SO WILL GO WITH RAPIDLY LOWERING
CHANCES FOR PRECIPITATION DURING THE EVENING. THE OVERNIGHT WILL BE
DRY.

SUNDAY/SUNDAY NIGHT...SUNDAY MORNING THE A SECOND 500 MB SHORTWAVE
PUSHES INTO THE REGION. THE GFS HAS THE 850-700 MB MOISTURE RH NEAR
70%  WITH THE +3C OR SO 850 MB TEMPERATURE. WITH THE NW FLOW AND THE
QG FORCING, WOULD EXPECT AT THE LEAST, SPRINKLES AND SELF-DESTRUCT
SUNSHINE. AS MENTIONED BEFORE, THE NAM AND ECMWF HAVE BACKED OFF.
SINCE I HAVE LOW POPS WILL KEEP IT IN FOR NOW. ONCE THE WAVE IS
PASSED THE REGION IN THE EVENING, THEN THE SKY CLEARS OVERNIGHT.

MONDAY...STRONG HIGH PRESSURE MOVES INTO THE GREAT LAKES, AND DRIES
THINGS OUT. THIS LOOKS LIKE IT WOULD ALLOW TEMPERATURES TO REBOUND
BACK INTO THE 70S.

EXTENDED (TUESDAY THRU FRIDAY)...WITH THE SLOW MOVEMENT OF FAY,
WILL HAVE TO PUT IN THE CAVEAT THAT THIS FORECAST MAY NOT PAN OUT
DUE TO THE MODELS INABILITY TO HANDLE THE TROPICAL SYSTEMS. WITH
THAT SAID...TUESDAY, THE SFC HIGH WILL CONTINUE TO BLOCK MOISTURE
FROM MOVING UP INTO THE GREAT LAKES. WEDNESDAY, TEMPERATURES GET
BACK TO 80 DEGREES AS THE HIGH MOVES TO THE EAST AND THE RETURN FLOW
BEGINS TO WARM THINGS. THURSDAY, THE COLD FRONT THAT WAS IN THE
ROCKIES ON YESTERDAYS RUN IS NOW IN MINNESOTA. THE REMNANTS OF FAY
ARE MOVING INTO THE TENNESSEE VALLEY. WILL ALLOW FOR THE CHANCE OF
THUNDERSTORMS. FRIDAY, THE FRONT CONTINUES TO SLOWLY MOVE INTO THE
WESTERN GREAT LAKES, AS THE REMNANTS FROM FAY CONTINUE TO MEANDER
IN THE TENNESSEE VALLEY. IF THIS HOLDS TRUE, THIS DAY MAY BE MORE
LIKELY THAT THERE WILL BE RAIN THAN THURSDAY, BUT THAT WILL REMAIN
TO BE SEEN.

LUTZ

&&

.MARINE...ISSUED 344 PM...WINDS OFF THE DECK ARE INCREASING
TODAY...BUT THE LOW LEVELS ARE STABLE OVER THE LAKES. NORTHERN LAKE
MI BUOY AND PT INLAND ARE GUSTING TO AROUND 20KT. BUT LONG FETCH IS
STARTING TO BUILD WAVES...WITH THE NORTHERN BUOY NEARING 4 FT. WILL
ISSUED AN SCA FOR THE FAR NORTH SHORE OF LAKE MI...AND CORRESPONDING
LAKESHORE STATEMENT FOR RIP CURRENTS.

JZ

&&

.AVIATION...ISSUED 117 PM...TSRA HAVE DEVELOPED ALONG THE LAKE MI
LAKE BREEZE BOUNDARY. THESE WILL IMPACT TVC FOR THE NEXT 1-2
HOURS...AND POTENTIALLY PLN AFTER THAT. WOULD ALSO EXPECT POP-UP
SHRA/TSRA NEAR APN THIS AFTERNOON. WITH LOSS OF HEATING AND DRIER
AIR MOVING IN ALOFT...PRECIP WILL DIMINISH THIS EVENING. LOW LEVELS
WILL REMAIN VERY MOIST...LOW CLOUDS (LOW MVFR TO HIGH END IFR)
SHOULD ARRIVE AT TVC/PLN OVERNIGHT. INCOMING COLD FRONT WILL SPAWN
ANOTHER ROUND OF SHRA/TSRA SATURDAY. BEST CHANCE THRU 18Z WILL BE AT
PLN.
