AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
324 PM EST TUE DEC 25 2012

.SYNOPSIS...
ISSUED AT 324 PM EST TUE DEC 25 2012

SNOW AND BLOWING SNOW TO BRING HAZARDOUS TRAVEL CONDITIONS WEDNESDAY
AND WEDNESDAY NIGHT ESPECIALLY TO LOCATIONS SOUTH AND EAST OF GRAND
RAPIDS.  OTHERWISE...SCATTERED CHANCES FOR ADDITIONAL LIGHT SNOW
POSSIBLE THROUGH THE REMAINDER OF THE NEXT SEVEN DAYS.

&&

.SHORT TERM...(THIS EVENING THROUGH THURSDAY NIGHT)
ISSUED AT 324 PM EST TUE DEC 25 2012

SNOW AND BREEZY CONDITIONS TO RETURN LATE WEDNESDAY MORNING THROUGH
WEDNESDAY EVENING...ESPECIALLY SOUTH AND EAST OF GRAND RAPIDS. THIS
SNOW AND ANY BLOWING SNOW TO CAUSE SOME TRAVEL HEADACHES ON AREA
ROADWAYS FOR ALL TRAVELERS. GREATEST IMPACT OF THIS STORM STILL
LOOK TO BE LOCATIONS ALONG AND TO THE SOUTH AND EAST OF INTERSTATE
69...INCLUDING US 127.

ACCUMULATIONS UP TO 4 INCHES POSSIBLE THE FURTHER SOUTH AND EAST
AWAY FROM I-69 YOU GO...BUT A GENERAL 2-4 INCH EVENT SOUTH OF I-69
IS SHAPING UP. WEST AND NORTH OF I-69 ACCUMULATIONS TAPER DOWN
FROM 2 INCHES TO NONE. A LINE FROM HOLLAND TO GRAND RAPIDS TO
ALMA AND POINTS NORTH APPEAR RIGHT NOW TO BE THOSE WHO HAVE THE
BEST CHANCE OF NOT RECEIVING ANY ACCUMULATING SNOW FROM THIS EVENT.
EXPECTATION IS THAT IF ACCUMULATION FORECAST WERE TO CHANGE OVER
THE NEXT 24 HOURS...IT WOULD LIKELY GO LOWER WITH HEAVIER AMOUNTS
SHIFTING FURTHER TO THE SOUTHEAST.

REGARDLESS...MAIN TRAVEL CORRIDORS LIKELY TO SEE THE IMPACTS OF
SOME SNOW ALONG WITH BLOWING SNOW SO PUBLIC ADVISORIES HAVE BEEN
POSTED FOR THIS EVENT.

SNOW AND WINDS EXIT QUICKLY OVERNIGHT WEDNESDAY NIGHT WITH ONLY
SOME LINGERING LIGHT SNOW OVER FAR SOUTHEAST LOWER MICHIGAN
THROUGH AROUND NOON THURSDAY.

.LONG TERM...(FRIDAY THROUGH TUESDAY)
ISSUED AT 324 PM EST TUE DEC 25 2012

CONFIDENCE HAS INCREASED THAT WE WILL SEE LIGHT SNOW IN THE FRIDAY
THROUGH SATURDAY TIME FRAME.  WARM ADVECTION AND ISENTROPIC LIFT ON
FRIDAY SHOULD BRING SNOW.  THEN AN INVERTED TROUGH PASSES THROUGH
FRIDAY NIGHT/SATURDAY...ADDING LIFT AND MOISTURE.  HOWEVER THIS SNOW
SHOULD BE LIGHT...IN THE ORDER OF AN INCH OR TWO OVER THE 36 HOUR
PERIOD.  HAVE INCREASED POPS FOR MOST AREAS THROUGH THESE PERIODS.

THE SATURDAY NIGHT THROUGH TUESDAY TIME FRAME LOOKS FAIRLY QUIET.
THERE MAY BE SOME LAKE EFFECT SNOW SHOWERS AROUND...BUT THESE LOOK
MINIMAL AS H8 TEMPS WARM ON SUNDAY.  THE GFS HINTS AT A STRONG SURGE
OF COLD AIR MONDAY NIGHT/TUESDAY WHICH COULD PERK UP THE LES...BUT
THE EURO IS MUCH MORE ZONAL WITH STABLE H8 TEMPS.

&&

ISSUED AT 1246 PM EST TUE DEC 25 2012

PATCHY MVFR CEILINGS AROUND THIS AFTERNOON.

NE WINDS WILL BEGIN TO INCREASE PRIOR TO DAYBREAK WED WITH GUSTS
TO 15 TO 20 KNOTS. AS A STORM SYSTEM APPROACHES ON WED...CEILINGS
WILL BEGIN TO LOWER BY MID MORNING. HOWEVER ANY SNOW SHOULD HOLD
OFF UNTIL AFTER 18Z.

AS AN OUTLOOK...THE SNOW IS EXPECTED TO BECOME STEADIER AFTER 21Z
WED FOR AZO...BTL...LAN AND JXN. IFR CONDITIONS WILL BE LIKELY BY THEN.
