AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
655 AM EST SAT DEC 3 2011

LATEST UPDATE...AVIATION...

.SYNOPSIS...(444 AM EST SAT DEC 3 2011)
LOW PRESSURE WILL MOVE OUT OF THE SOUTHERN PLAINS TODAY AND MOVE TO
LAKE MICHIGAN BY SUNDAY MORNING.  THIS WILL BRING RAIN TO THE
AREA.  AREAS TO THE NORTH AND WEST OF GRAND RAPIDS WILL SEE THE
STEADIEST RAIN INTO SUNDAY.  BUT ALL AREAS WILL SEE PERIODS OF RAIN
THROUGH THE WEEKEND.  SUNDAY NIGHT SHOULD BE DRY BUT COOLER AS THE
SYSTEM LIFTS AWAY FROM THE AREA.  ANOTHER LOW PRESSURE IS EXPECTED
TO MOVE INTO THE OHIO VALLEY INTO MONDAY.  THIS COULD BRING
ACCUMULATING SNOW TO PARTS OF SOUTHERN LOWER MICHIGAN.

&&

.SHORT TERM...(444 AM EST SAT DEC 3 2011)
(TODAY THROUGH MONDAY)
UPSTREAM PCPN WAS ALREADY MOVING ACROSS LAKE MICHIGAN AS OF 09Z.
THIS EARLIER ARRIVAL LEADS TO A POSSIBLE MIX AT THE ONSET OF PCPN
THIS MORNING.  HOWEVER...THIS SHOULD BE BRIEF AND IMPACTS ARE NOT
ANTICIPATED.  THIS PCPN WAS ON THE LEADING EDGE OF IMPRESSIVE
ISENTROPIC LIFT.  THIS SITS OVER THE NORTHERN HALF OF THE CWA
THROUGH THE MORNING HOURS...THEN LIFTS TO THE NORTH BY LATE IN THE
DAY.  THEREFORE HAVE RAISED POPS TO CATEGORICAL ACROSS THE NORTH FOR
THIS MORNING...INTO THE AFTERNOON.

LOW PRESSURE MOVES FROM MKC TO TVC OVERNIGHT.  THIS WILL BRING A DRY
SLOT THROUGH EARLY IN THE EVENING.  BUT THEN DEEPER MOISTURE RETURNS
WITH THE APPROACH OF A TRAILING COLD FRONT LATE TONIGHT.  THE STEADY
RAINS WILL RETURN AFTER 06Z WITH THE ASSISTANCE OF A LOW LEVEL JET.

THE FRONT CUTS ACROSS THE CWA SUNDAY MORNING SO THE RAIN WILL
PERSIST...ALTHOUGH IT SHOULD LET UP CONSIDERABLY...OR EVEN END INTO
THE AFTERNOON.

ATTENTION THEN TURNS TO A POSSIBLE NORTHERN AND SOUTHERN STREAM
MERGER INTO MONDAY.  THE FRONT STALLS TO OUR SOUTH AND A NORTHERN
STREAM SHORT WAVE ADDS ENERGY TO IT.  THE MODELS ARE MORE AGGRESSIVE
NOW SHOWING A RESPONSE AND DEVELOPING LOW PRESSURE IN THE OHIO
VALLEY.  THE COLDER REGIME WOULD LEAD TO POSSIBLE SNOW ACCUMULATION
FOR SOUTHERN LOWER.  FGEN SOUTH OF I-96 LOOKS IMPRESSIVE BY THE END
OF THE DAY AND THE RIGHT ENTRANCE OF THE UPPER JET COULD BE OVER
THIS SAME AREA.  FOR NOW WILL INCREASE POPS TO LIKELY OVER THE SE
CWA...WITH AT LEAST LIGHT ACCUMS EXPECTED.

&&

.LONG TERM...(444 AM EST SAT DEC 3 2011)
(MONDAY NIGHT THROUGH FRIDAY)
ANOTHER ACCUMULATING SNOW EVENT IS LOOKING MORE LIKELY FOR AREAS
SOUTH AND EAST OF GRR ON MONDAY NIGHT. DEEP/POSITIVE TILT LONGWAVE
TROUGH REMAINS TO OUR WEST AND A WAVE HEADS NORTHEAST ALONG THE
BAROCLINC ZONE ACROSS THE OHIO VALLEY.

THIS IS A TRACK SOMEWHAT SIMILAR TO THE LAST EVENT... BUT IT/S AN
OPEN WAVE WITH A BIT LESS MOISTURE. STILL... THE MID LEVEL FGEN
LOOKS QUITE STRONG AGAIN WITH POTENTIAL FOR UPR LVL JET COUPLING.

MODEL QPFS HAVE TRENDED NORTH AND HAVE RAISED POPS TO LIKELY IN THE
SE CWFA. PCPN TYPE DOES NOT APPEAR TO BE MUCH OF A CHALLENGE UNLESS
THE STORM TRACK SHIFTS FARTHER NORTH. WENT WITH ALL SNOW ATTM.

TOWARD THE END OF THE WEEK AND NEXT WEEKEND A PATTERN CHANGE TOWARD
COLDER WEATHER WITH INCREASED LAKE EFFECT POTENTIAL IS PROGGED TO
OCCUR. POLAR VORTEX BECOMES POSITIONED OVER HUDSON BAY WITH A
BROAD/DEEP CYCLONIC FLOW EXTENDING SOUTH INTO THE NRN UNITED
STATES.

THIS FEATURE EVENTUALLY UNLEASHES A COLD CANADIAN AIR MASS WHICH WE
HAVE YET TO EXPERIENCE THIS WINTER. IT WILL PROBABLY COME DOWN IN
OCNL/GRADUAL PIECES VIA A SERIES OF TROUGHS/COLD FRONTS
(THURSDAY-FRIDAY)... EACH OF WHICH COULD BRING BOUTS OF ACCUMULATING
LAKE EFFECT/ENHANCED SNOW. THE COLDEST OF AIR OF AROUND -18C AT H8
IS PROGGED TO ARRIVE FOR NEXT WEEKEND.

&&

.AVIATION...(655 AM EST SAT DEC 3 2011)
RAIN SHOWERS AND HIGHER SFC DEW POINTS SPREADING INTO THE REGION
TODAY SHOULD RESULT IN FAIRLY WIDESPREAD MVFR CATEGORY CONDITIONS...
WITH SOME SPOTTY IFR AS WELL. THE IFR POTENTIAL IS HIGHEST AT MKG
AND GRR AS THESE LOCATIONS HAVE A BETTER CHANCE AT HEAVIER/MORE
FREQUENT RAINFALL BEING CLOSER TO THE SFC FRONT.

THERE IS DECENT POTENTIAL AT WIDESPREAD VFR DEVELOPING LATER THIS
AFTERNOON AND TONIGHT AS SHOWERS TEMPORARILY END AND A DRIER AIR
MASS ARRIVES FROM THE SOUTH. THIS IS WHEN WE WILL ACTUALLY BE
TRULY IN THE WARM SECTOR... WITH BREEZY SFC SOUTH WINDS.

RAIN AND LOWER CIGS/VSBYS ARE EXPECTED TO RETURN FROM THE WEST LATE
TONIGHT AFTER 08Z OR SO AS THE COLD FRONT APPROACHES.

&&

.MARINE...(444 AM EST SAT DEC 3 2011)
SMALL CRAFT ADVISORY WILL BE EXPANDED TO ALL NSH AREAS WITH BRISK
SOUTHERLY WINDS CONTINUING.

&&

.HYDROLOGY...(444 AM EST SAT DEC 3 2011)
RAINFALL OVER THE WEEKEND SHOULD AVERAGE AROUND A HALF INCH.
PERHAPS A BIT MORE NW...AND LESS SE.  THIS WILL KEEP RIVER LEVELS
ABOVE NORMAL.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
LM...SMALL CRAFT ADVISORY SOUTH HAVEN TO MANISTEE THROUGH SUNDAY
     NIGHT.
     SMALL CRAFT ADVISORY ST. JOSEPH TO SOUTH HAVEN TODAY.
