AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
436 AM EDT WED SEP 19 2012

.SYNOPSIS...
ISSUED AT 435 AM EDT WED SEP 19 2012

HIGH PRESSURE WAS OVER THE OHIO VALLEY THIS MORNING. THIS HIGH WILL
LIFT INTO NEW ENGLAND TODAY...AS LOW PRESSURE ADVANCES FROM NEAR
LAKE WINNIPEG INTO LAKE SUPERIOR BY TONIGHT. WINDS WILL SHIFT THE
SOUTHWEST AND BECOME BREEZY...DISRUPTING AND ENDING THE LAKE EFFECT
SHOWERS. HOWEVER...THE NEXT COLD FRONT WILL RETURN SHOWERS TO ALL OF
NORTHERN MICHIGAN TONIGHT. LAKE EFFECT SHOWERS WILL REDEVELOP
TOMORROW...AND THEN LAST THROUGH THE WEEKEND...AS MULTIPLE SHOTS OF
REINFORCING COOL AIR SETTLE OVER THE REGION.

&&

.SHORT TERM...(TODAY THROUGH TONIGHT)
ISSUED AT 435 AM EDT WED SEP 19 2012

MIDNIGHT SURFACE/COMPOSITE ANALYSIS SHOWS 1019MB HIGH CENTERED OVER
SOUTHERN MISSOURI...WITH A SHARP RIDGE AXIS EXTENDING NORTH ACROSS
EASTERN WISCONSIN/WESTERN UPPER/LAKE SUPERIOR.  A NORTH-SOUTH
ORIENTED WARM FRONT WAS STRETCHED OUT FROM LAKE WINNIPEG SOUTH
ACROSS THE EASTERN DAKOTAS.  STRONG MID LEVEL TROUGH AXIS MOVING
ACROSS THE GREAT LAKES/OHIO VALLEY WITH AN IMPRESSIVE COLD POOL (00Z
500MB TEMPERATURE OFF APX SOUNDING -27C)...WITH ANOTHER SHORT WAVE
TROUGH ON ITS HEELS DIGGING SOUTHEAST ACROSS SOUTHERN MANITOBA.
BAND OF MID/HIGH CLOUDS ASSOCIATED WITH THIS FEATURE AND THE WARM
ADVECTION PATTERN AHEAD OF IT ACROSS THE NORTHERN PLAINS/UPPER
MIDWEST.  CLOSER TO HOME...LAKE EFFECT CLOUDS AND SPOTTY SHOWERS
CONTINUE ACROSS EASTERN UPPER/NORTHWEST LOWER...WITH MORE CLEARING
OVER NORTHEAST LOWER.  00Z APX SOUNDING 850MB TEMPERATURES OF 0C
WITH A NON-EXISTENT INVERSION (GRB SOUNDING SIMILAR BUT WITH AN
INVERSION AROUND 700MB)...ABOUT 10-15KTS OF NORTHWESTERLY 1000-850MB
FLOW TO THE EAST OF APPROACHING LOW LEVEL RIDGE AXIS.

AS LEAD TROUGH DEPARTS THIS MORNING AND BRIEFLY REPLACED BY
RIDGING...ATTENTION WILL TURN TO UPSTREAM WAVE AND ASSOCIATED COLD
FRONT WHICH ARE FORECAST TO MOVE INTO MICHIGAN TONIGHT.  THE COLD
FRONT IS EXPECTED TO CROSS THE FORECAST AREA IN THE 06Z-15Z TIME
FRAME...AND IMPACTS WITH THIS SYSTEM WILL BE THE MAIN CONCERN IN THE
SHORT TERM PORTION OF THIS FORECAST CYCLE.

TODAY...STILL HAVE SOME PERSISTENT SHOWERS COMING IN OFF THE LAKES
EARLY ON...WITH SOME SQUIRRELY THINGS GOING ON WITH LOW LEVEL
WINDS. IN PARTICULAR A SOUTHWEST MOVING BOUNDARY CLEARLY EVIDENT
ON RADAR COMING ACROSS THE TIP OF THE MITT (AND PULLING WINDS
AROUND TO THE NORTHEAST) HAS RESULTED IN A BROKEN LINE OF SHOWERS
FROM GLR WEST ACROSS THE GRAND TRAVERSE BAY REGION.  LOW LEVEL
RIDGING OVER EASTERN WISCONSIN WILL SLIDE EAST PRETTY QUICKLY THIS
MORNING...TO BE REPLACED BY INCREASING SOUTHERLY FLOW LATER THIS
MORNING AS UPSTREAM COLD FRONT PLOWS ACROSS THE UPPER MIDWEST.
DRIER AIR BEHIND THIS RIDGE AXIS/BACKING LOW LEVEL WINDS/INCREASING
SYNOPTIC SCALE SUBSIDENCE BEHIND DEPARTING MID LEVEL TROUGH WILL
DECREASE LAKE CLOUDS THROUGH MID MORNING (THOUGH SOME RESIDUAL SC
EXPECTED OVER PARTS OF NORTHERN LOWER AIDED BY SOME EARLY
HEATING). MEANWHILE...UPSTREAM AC/CI WILL ALREADY BE KNOCKING ON
THE DOOR BY MID MORNING...AND WILL OVERSPREAD NORTHERN MICHIGAN BY
MIDDAY. LOW LEVELS UPSTREAM ARE DRY...WITH JUST A FEW SPRINKLES
OCCURRING OVER NORTHWEST ONTARIO. SO WILL PROBABLY SEE A GOOD BIT
OF VIRGA ON THE RADAR...MAYBE A LITTLE BIT OF RAIN REACHING THE
GROUND ACROSS THE TIP OF THE MITT AND THE EASTERN U.P. TOWARD
MIDDAY. LATER THIS AFTERNOON...AS NEXT SHORT WAVE TROUGH DROPS
INTO THE UPPER MISSISSIPPI VALLEY AND ASSOCIATED COLD FRONT MOVES
INTO WISCONSIN...UPPER DYNAMICS INTERACTING WITH THE LOW LEVEL
BOUNDARY EXPECTED TO DEVELOP A BAND OF RAIN SHOWERS ACROSS
CENTRAL/EASTERN WISCONSIN AND EXTENDING NORTHEAST INTO THE UPPER
PENINSULA BY LATE AFTERNOON. SO BEST CHANCE FOR RAIN TODAY LOOKS
TO BE NORTH OF THE BRIDGE DURING THE AFTERNOON HOURS. TIGHTENING
GRADIENT AND INCREASING MIXED LAYER FLOW EXPECTED TO GET THE WINDS
CRANKING UP THIS AFTERNOON...PARTICULARLY ACROSS NORTHWEST LOWER
AND WESTERN PORTIONS OF MACKINAC COUNTY WHERE WIND GUSTS OVER 30
MPH EXPECTED.

TONIGHT...COUPLE OF OPPORTUNITIES FOR RAIN TONIGHT ACROSS THE
FORECAST AREA.  ABOVE MENTIONED FRONTAL RAIN BAND EXPECTED TO
DEVELOP THIS AFTERNOON ON THE OTHER SIDE OF LAKE MICHIGAN WILL BE
THE INITIAL CHANCE AS IT SPREADS INTO NORTHERN MICHIGAN FROM THE
WEST DURING THE EVENING HOURS.  THE ACTUAL COLD FRONT WILL BE
TRAILING THE RAIN BAND...AND AS IT CROSSES LAKE MICHIGAN THERE MAY
BE ENOUGH INSTABILITY TO ALLOW A BAND OF CONVECTION TO POP ALONG THE
BACK SIDE OF THE INITIAL RAIN BAND (WITH GUSTY WINDS??).  THIS MAY
EVENTUALLY TRANSITION TO A PERIOD OF LAKE INDUCED SHOWERS IN
POST-FRONTAL WESTERLY FLOW OFF LAKE MICHIGAN.  SO A LOT TO
CONSIDER...BUT PERIODS OF RAIN/CHANCE THUNDER EASTERN UPPER AND
NORTHWEST LOWER SHOULD COVER THINGS.

.LONG TERM...(THURSDAY THROUGH TUESDAY)
ISSUED AT 435 AM EDT WED SEP 19 2012

A LONG WAVE TROUGH WILL CONTINUE TO DIG ITS HEELS INTO THE REGION
THROUGH THIS WEEKEND THEN LIKELY FINALLY BEGIN TO LIFT OUT OF THE
REGION EARLY NEXT WEEK. THIS WILL LEAD TO CONTINUED COOL AND
UNSETTLED WEATHER THROUGH THIS WEEKEND AS SHORT WAVES ROTATE THROUGH
THE FLOW. MILDER AND LIKELY DRIER WEATHER IS THEN EXPECTED EARLY
NEXT WEEK AS HEIGHTS FINALLY BEGIN TO REBOUND. THE MAIN LONG TERM
FORECAST CONCERNS REVOLVE AROUND POPS THROUGH THIS WEEKEND.

THURSDAY INTO THURSDAY NIGHT...SHORT WAVE ENERGY DIGS SOUTHEAST
THROUGH THE LONG WAVE TROUGH AND LOOKS LIKE IT WILL GRAZE THE
NORTHERN THIRD OF THE FORECAST AREA. THIS FEATURE IN COMBINATION
WITH DECENT OVER LAKE INSTABILITY LIKELY BRINGS MORE LAKE EFFECT
RAIN SHOWERS THURSDAY INTO THURSDAY NIGHT (MEAN SURFACE-850 MB FLOW
JUST SOUTH OF WEST). HIGHS IN THE UPPER 50S TO MIDDLE 60S. LOWS IN
THE MIDDLE 40S TO LOWER 50S.

FRIDAY THROUGH SUNDAY...THE LONG WAVE TROUGH AMPLIFIES AND DIGS INTO
THE NORTHERN GREAT LAKES...INCREASING OVER LAKE INSTABILITY ONCE
AGAIN. MEANWHILE...AT LEAST A COUPLE OF FAIRLY STRONG SHORT WAVES
MOVE THROUGH THE FLOW FRIDAY INTO THE WEEKEND SO WILL HAVE
CATEGORICAL POPS FRIDAY THEN HIGH CHANCE OR LIKELY POPS OVER THE
WEEKEND. HIGHS FRIDAY RANGING FROM THE MIDDLE 50S TO MIDDLE 60S THEN
ONLY THE MIDDLE TO UPPER 50S SATURDAY AND SUNDAY. LOWS IN THE UPPER
30S AND 40S.

MONDAY AND TUESDAY...EXTENDED MODELS ARE IN FAIR AGREEMENT THAT
HEIGHTS BEGIN TO REBOUND WITH DECREASING OVER LAKE INSTABILITY.
THEREFORE...WE MAY ACTUALLY GO A COUPLE OF DAYS WITHOUT ANY
PRECIPITATION. MILDER WITH HIGHS MAINLY IN THE 60S AND LOWS IN THE
40S.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z WEDNESDAY NIGHT)
ISSUED AT 204 AM EDT WED SEP 19 2012

WINDS BACKING TO THE SOUTHWEST OVERNIGHT WITH VFR LAKE CLOUDS STILL
LINGERING CLOSE TO THE LAKE MICHIGAN SHORELINE.  TIGHTENING PRESSURE
GRADIENT ON WEDNESDAY AS UPPER TROF DIGS INTO THE UPPER MIDWEST.
WARM SOUTHWEST WINDS WILL GUST TO 20+ KTS DURING THE AFTERNOON WITH
INCREASING MID LEVEL CLOUDINESS.  SHOWERS WILL OVERSPREAD THE AREA
FROM WEST-EAST WEDNESDAY NIGHT WITH LOWERING CIGS TOWARD MVFR.

&&

.MARINE...
ISSUED AT 435 AM EDT WED SEP 19 2012

HIGH PRESSURE RIDGE SLIDES QUICKLY ACROSS THE UPPER GREAT LAKES THIS
MORNING...FOLLOWED BY INCREASING SOUTHERLY WINDS THIS MORNING.
WINDS WILL RAMP UP QUICKLY ON LAKE MICHIGAN...LIKELY REACHING GALE
FORCE GUSTS BY MID/LATE AFTERNOON.  DESPITE LOW LEVEL WARM
ADVECTION...MAGNITUDE OF WARM AIR ISN'T ENOUGH TO LIMIT OVER WATER
INSTABILITY GIVEN CLIMATOLOGICAL LAKE WARMTH.  SO GALE WARNINGS WILL
BE RAISED WITHIN ALL LAKE MICHIGAN NEARSHORE ZONES FROM ROUGHLY NOON
THROUGH MIDNIGHT.  STRONG WINDS WILL THEN MIGRATE OVER THE LAKE
HURON NEARSHORE WATERS TONIGHT...OFFSHORE WINDS MAY BE A BIT
MARGINAL FOR THE NORTHERN LOWER NEARSHORE ZONES (INCLUDING THE
STRAITS)...BUT ISN'T GOING TO TAKE MUCH TO PULL DOWN GALE FORCE
GUSTS WITH 40KT WINDS FORECAST JUST OFF THE DECK.  SO WILL STRETCH
GALE WARNING INTO ALL LAKE HURON NEARSHORE ZONES FOR TONIGHT.  SMALL
CRAFT ADVISORIES WILL BE HOISTED FOR WHITEFISH BAY/ST. MARY'S
RIVER...THOUGH WON'T RULE OUT THESE AREAS ALSO SEEING GALE FORCE
WIND GUSTS BY LATE AFTERNOON.
