AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
400 PM EST SAT DEC 27 2008

.SYNOPSIS.../ISSUED AT 400 PM/

LOW PRESSURE WILL TRACK UP INTO LOWER MICHIGAN TONIGHT...THEN
RAPIDLY INTENSIFY OVER THE STATE SUNDAY MORNING BEFORE TRACKING
FURTHER INTO CANADA. AS THIS OCCURS...A STRONG COLD FRONT WILL BLAST
INTO THE GRAND TRAVERSE BAY REGION AROUND DAYBREAK THEN PLOW
THROUGH THE REMAINDER OF NORTHERN MICHIGAN SUNDAY MORNING. SNOWFALL
IS EXPECTED TO BREAK OUT ACROSS EASTERN UPPER AND MAINLY NORTHWEST
LOWER MICHIGAN...WHILE WINDS INCREASE TO GUSTS IN THE 30 TO 40 MPH
RANGE. NEAR BLIZZARD CONDITIONS ARE POSSIBLE WITH SOME ACCUMULATING
SNOWFALL. TEMPERATURES ON SUNDAY WILL RAPIDLY DROP FROM 40S EARLY IN
THE MORNING INTO THE 20S BY AFTERNOON. THE SNOW AND STRONGEST WINDS
WILL QUICKLY DIMINISH SUNDAY AFTERNOON...ALTHOUGH WINDS WILL STAY ON
THE GUSTY SIDE THROUGH THE DAY.

ADAM

&&

.SHORT TERM.../ISSUED AT 400 PM/...TONIGHT

POTENT SRN STREAM SHORT WAVE NOW TRACKING QUICKLY INTO THE MID
MISSISSIPPI RIVER VALLEY THIS AFTERNOON. COMBINED WITH ASSOCIATED
STRONG UPPER JET DYNAMICS ALSO PUNCHING UP TOWARD THE REGION...
SURGE OF HEAVIEST RAINFALL NOW HEADING TOWARD NRN MICHIGAN FOR
TONIGHTS WEATHER...ALONG WITH A FEW EMBEDDED BOWING TSTM SEGMENTS
TAKING AIM ON SRN LOWER MICHIGAN. SO TONIGHTS WEATHER IS PRETTY
STRAIGHT FORWARD...CATEGORICAL RAIN FOR ALL AND A CHANCE FOR THUNDER
ACROSS A GOOD PORTION OF NRN LOWER MICHIGAN. FIRST OFF IN THE
HEADLINE DEPARTMENT...HAVE ALREADY EXTENDED DENSE FOG ADVISORY
THROUGH THIS EVENING. FOG/VSBYS HAVE BOUNCED AROUND THROUGH THE DAY
AND WILL CONTINUE TO DO SO TONIGHT AS HEAVIER RAIN MOVES THROUGH.
BUT AS TEMPS COOL SLIGHTLY THIS EVENING AND GIVEN ALL THE DENSE FOG
DRIFTING AROUND OFF THE SNOWPACK...SEE NO REASON TO CANCEL IT.

THEN...MAIN FORECAST CHALLENGE COMES LATE OVERNIGHT THROUGH SUNDAY
AS SFC LOW QUICKLY DEEPENS OVERHEAD BEFORE TRACKING INTO CANADA BY
AFTERNOON. AS THIS OCCURS...COLD AIR WILL SLAM BACK THROUGH THE
FORECAST AREA EARLY SUNDAY MORNING KNOCKING TEMPS QUICKLY DOWN FROM
THE 40S/50S INTO THE 20S/30S BY MID TO LATE MORNING AND CHANGING
REMAINING SYNOPTIC PRECIP QUICKLY FROM RAIN TO SNOW. NOT LOOKING TO
BE A BIG SNOW PRODUCER WITH PERHAPS ONLY 1-3 INCHES OF ACCUMULATION
OVER NW LOWER MICHIGAN AT BEST FROM COMBINED SYNOPTIC AND LAKE
ENHANCEMENT. PROBABLY A LITTLE BETTER SNOW ACCUMULATIONS (2-4
INCHES) WILL BE HAD ACROSS EASTERN UPPER MICHIGAN...BUT STILL SHORT
OF ANY WARNING CRITERIA.

BUT BIGGEST PROBLEM WILL RESULT FROM THE WINDS. CORE OF STRONGEST
WINDS ALOFT LOOKING TO SLIDE THROUGH THE S/E PORTION OF THE CWA
EARLY SUNDAY MORNING...AND PERHAPS SLIGHTLY AHEAD OF THE STRONGEST
COLD ADVECTION/SURGE OF MOMENTUM TO THE SFC. REGARDLESS...GIVEN THE
RAPID INTENSIFICATION OF THE SFC LOW/PRESSURE GRADIENT...THERE WILL
BE A 3 TO 6 HOUR PERIOD SUNDAY MORNING WITH WINDS GUSTING UP NEAR 40
MPH ACROSS EASTERN UPPER AND NW LOWER MICHIGAN PRODUCING SUBSTANTIAL
BLOWING SNOW AND REDUCED VSBYS....ESPECIALLY ALONG THE LAKESHORES
BEFORE THINGS SETTLE DOWN BY AFTERNOON. GIVEN THE RELATIVELY LOW
QPF/SNOW AMOUNTS AND ONLY MARGINAL LAKE CONTRIBUTIONS...OUTSIDE OF
THE IMMEDIATE LAKE SHORE AREAS STILL DONT THINK THAT STRICT BLIZZARD
CONDITIONS WILL BE ATTAINED. BUT I THINK ITS TOO CLOSE AND
CONDITIONS WILL BE TOO HAZARDOUS TO HANDLE WITH JUST AN ADVISORY.

SO FOR HEADLINES...PLAN TO HOIST   RELATIVELY SHORT LIVED WINTER
STORM WARNING FOR EASTERN UPPER AND MOST OF NW LOWER MICHIGAN TO
HANDLE THE IMPACT. WARNING WILL RUN THROUGH THE DAY ALTHOUGH
CONDITIONS MAY IMPROVE SUBSTANTIALLY ENOUGH SUNDAY AFTERNOON FOR THE
WARNING TO BE CANCELLED EARLY. FOR THE REST OF THE FORECAST
AREA...WILL SURROUND THE WARNING WITH ONE TIER OF COUNTIES IN A
WINTER WEATHER ADVISORY. REST OF THE COUNTIES IN NRN LOWER MICHIGAN
WILL GO INTO A WIND ADVISORY.

HYDRO ISSUES...LARGEST SLUG OF RAINFALL WILL COME THROUGOURS WITH AN OVERALL 1 TO 2 INCHES OF TOTAL RAINFALL
OCCURRING OVER THE LOWER PENINSULA. SNOW MELT THEN CONTINUES THROUGH
EARLY SUNDAY MORNING BEFORE TEMPS CRASH. STILL AN UNKNOWN JUST WHAT
KIND OF HYDRO RESPONSE WE WILL SEE AND CURRENT PLACEMENT OF FLOOD
WATCH APPEARS FINE GIVEN THE CURRENT AND EXPECTED HEAVIEST TOTAL
RAINFALL AND CONSIDERING OUR MOST FLOOD PRONE AREAS (S/SE COUNTIES).
WITH THAT SAID...EVEN THROUGH TEMPS WILL QUICKLY DROP BELOW FREEZING
ON SUNDAY...BEST HYDRO RESPONSE MAY LAG INTO SUNDAY ESPECIALLY ON
THE RIVERS. IN FACT...LATEST RFC RIVER FORECASTS HAVE STAGES PEAKING
LATE SUNDAY INTO MONDAY (SEE POINT SPECIFIC FLOOD WATCH ISSUED FOR
THE MANISTEE RIVER NEAR SHERMAN). FOR THAT REASON...HAVE EXTENDED
AREAL FLOOD WATCH INTO SUNDAY...AND JUST WAIT AND SEE WHAT HAPPENS.

ADAM

&&

.LONG TERM.../ISSUED AT 400 PM/...SUNDAY NIGHT AND BEYOND

REMAINDER OF THE FORECAST (SUNDAY NIGHT THROUGH NEXT SATURDAY)...
HOPE EVERYONE ENJOYED THE ONE DAY OF SPRINGLIKE CONDITIONS. WHILE IT
LOOKS LIKE THE PATTERN WILL DEAMPLIFY FOR A TIME NEXT WEEK...RIPPLES
IN THE FLOW WILL CONTINUE TO BRING CHANCES FOR MORE SNOW. THE MAIN
FORECAST CONCERNS WILL REVOLVE AROUND POPS THROUGH THE PERIOD.

SUNDAY NIGHT...STRONG SUBSIDENCE ALONG WITH LOTS OF DRY AIR (850-700
MB RH 25 PERCENT OR SO) SHOULD YIELD PARTLY STARRY CONDITIONS. LOWS
IN THE UPPER TEENS AND LOWER 20S WITH DIMINISHING WINDS.

MONDAY...ENERGY NOW JUST OFF THE BRITISH COLUMBIA COAST PER CURRENT
WATER VAPOR SATELLITE LOOP ROCKETS EASTWARD ON THE HEELS OF A 120
KNOT 250 MB JET. ECMWF/UKMET/GFS ARE ALL SUFFICIENTLY COLD FOR ALL
SNOW WHILE NAM THERMAL PROFILES SUPPORT MORE OF A MIX OF RAIN/SNOW.
WILL GO WITH MODEL CONSENSUS WHICH LINES UP WITH SURROUNDING OFFICES
AND HAVE ALL SNOW. THIS CLIPPER SYSTEM PASSES BY TO OUR NORTH BUT
MODELS ARE IN AGREEMENT THAT THERE IS ADEQUATE MOISTURE (900-700 MB
RH ABOUT 90 PERCENT) AND SOME WEAK UPWARD FORCING ACROSS THE
FORECAST AREA. THEREFORE....HAVE RAISED POPS INTO THE 40 TO 50
PERCENT RANGE. SNOWFALL ACCUMULATIONS ARE EXPECTED TO GENERALLY
RANGE FROM AROUND AN INCH NORTH TO LESS THAN A HALF INCH SOUTH.
HIGHS GENERALLY IN THE MILD 30S.

MONDAY NIGHT...COOLER AIR WILL INCREASE OVER LAKE INSTABILITY BUT
THIS WILL BE BALANCED OUT BY MORE DRY AIR (850-700 MB 25 PERCENT OR
SO). FOR NOW WILL CONTINUE WITH THE 30 POP BUT LATER SHIFTS MAY BE
ABLE TO PULL THIS. LOWS IN THE UPPER TEENS AND LOWER 20S AGAIN.

TUESDAY...A STRONGER CLIPPER SYSTEM COMES OFF THE PACIFIC AND TRACKS
FARTHER SOUTH. MODELS ARE IN AGREEMENT THAT THE BEST QPF IS ACROSS
NORTHERN MICHIGAN (A QUARTER TO A THIRD OF AN INCH) SO HAVE RAISED
POPS TO 40 TO 50. COULD SEE A GENERAL 2 TO 4 INCH SNOWFALL WITH THIS
ONE. A BIT COOLER WITH HIGHS IN THE UPPER 20S AND LOWER 30S.

WEDNESDAY THROUGH SATURDAY...LOOKS LIKE ANOTHER SHOT OF ARCTIC AIR
(-17 TO -20 C) TO END 2008. AIRMASS LOOKS ON THE DRIER SIDE THOUGH
SO JUST A CHANCE OF SNOW SHOWERS AT THIS POINT FOR WED/THU. YET A
STRONGER SYSTEM MAY AFFECT THE REGION AS EARLY AS THURSDAY NIGHT
WHICH COULD LINGER RIGHT INTO FRIDAY NIGHT. WAY TO FAR OUT TO
PROJECT SNOWFALL AMOUNTS BUT THIS WILL BE INTERESTING TO FOLLOW
THROUGH THE WEEK. HIGHS CLOSE TO SEASONABLE LEVELS (MAINLY 20S).

SULLIVAN

&&

.MARINE.../ISSUED AT 400 PM/

POTENT LOW PRESSURE SYSTEM EXPECTED TO SPIN UP OVER NRN MICHIGAN ON
SUNDAY AND WILL BRING A PERIOD OF VERY STRONG WINDS TO THE REGION...
AS COLDER AIR SLAMS BACK INTO THE STATE. SOLID GALE FORCE GUSTS WILL
BE REALIZED ACROSS ALL NEARSHORE AREAS SUNDAY. CORE OF STRONGEST
WINDS WILL SLIDE THROUGH THE SAGINAW BAY AREA INTO LAKE HURON
BRINGING THE POTENTIAL FOR STORM FORCE GUSTS FOR THE STURGEON POINT
TO ALABASTER NEARSHORE ZONE...OUT INTO THE OPEN LAKE.

ADAM

.AVIATION.../ISSUED AT 1230 PM/...VALID FOR 18Z TAFS

WARM MOIST AIR CONTINUES TO SURGE OVR THE GREAT LAKES...IN ADVANCE
OF A STRONG UPPER MIDWEST STORM SYSTEM MOVING EAST. THE WARM AIR HAS
RESULTED IN IFR/LIFR CONDS IN FOG/RAIN AND STRATUS DECK THRU MUCH OF
THE MORNING. BRIEF PERIODS OF MVFR CONDS HAVE BEEN NOTED OVR NRN
MI...HOWEVER WITH DEEP SNOW PACK STILL IN PLACE AND SFC TEMPS AND
DEW PTS LINGERING IN THE UPPER 40S AND LOWER 50S...WILL CONT
IFR/LIFR CONDS OVR KPLN/KTVC/KAPN TAF SITES THIS AFTERNOON AND MUCH
OF THE OVERNIGHT PERIOD. WILL BEGIN TO IMPROVE CONDS TO MVFR SUNDAY
MORNING ACROSS KTVC/KPLN...AND KAPN IN THE AFTERNOON AS A COLD FRONT
PASSES OVER THE REGION BRINGING A RETURN TO COOLER AND DRIER
CONDITIONS. HOWEVER WINDS BEHIND THE EASTWARD MOVING SYSTEM...WILL
BE STRONG AND ANY SNOWFALL WILL GENERATE WIDESPREAD BLOWING SNOW
ACROSS KPLN/KTVC SUNDAY MORNING AND KAPN SUNDAY AFTN. WILL CONT LLWS
IN TAF SITES THRU THE EVENING. MODEL SOUNDINGS SHOWING SOUTHWEST
WINDS TO 45 KTS AT 2000FT WITH MORE STABLE SFC WINDS FROM THE S/SE
AT 10 KTS.
