AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
330 PM EST WED DEC 5 2012

.SYNOPSIS...
ISSUED AT 255 PM EST WED DEC 5 2012

SCATTERED LIGHT RAIN EXPECTED LATE THURSDAY NIGHT AND FRIDAY
ACROSS SOUTHERN LOWER MICHIGAN. RAIN MAY MIX WITH SNOW AT TIMES
ACROSS NORTHERN LOWER MICHIGAN FRIDAY MORNING. ADDITIONAL CHANCES
FOR RAIN OR SNOW COMES LATE THIS WEEKEND WITH ACCUMULATING SNOW
POSSIBLE ACROSS THE ENTIRE REGION LATE SUNDAY THROUGH TUESDAY.

&&

.SHORT TERM...(THIS EVENING THROUGH FRIDAY NIGHT)
ISSUED AT 255 PM EST WED DEC 5 2012

WEAK FRONT TO BRING SCATTERED LIGHT RAIN TO THE AREA THURSDAY
NIGHT AND EARLY FRIDAY...WITH LIGHT RAIN MAYBE MIXING WITH LIGHT
SNOW FRIDAY MORNING ACROSS NORTHERN LOWER MICHIGAN. LIGHT PRECIPITATION
LINGERS THROUGH FRIDAY NIGHT WHICH COULD BE IN THE FORM OR RAIN OR
A RAIN SNOW MIX. NO ACCUMULATION EXPECTED AT THIS TIME...THOUGH
SOME LOCATIONS NORTH OF I-96 COULD SEE A TENTH OR TWO ACCUMULATE
MAINLY ON GRASSY SURFACES LATE FRIDAY NIGHT.

.LONG TERM...(SATURDAY THROUGH WEDNESDAY)
ISSUED AT 255 PM EST WED DEC 5 2012

MAIN FOCUS WAS THE POTENTIAL FOR A WINTRY STORM SYSTEM IMPACTING THE
REGION SUNDAY INTO MONDAY.

A BOUNDARY STALLS OVER THE OHIO VALLEY SATURDAY/SATURDAY NIGHT AS A
NORTHERN STREAM TROUGH BEGINS SHARPEN OVER THE ROCKIES.  A STRONG
UPPER JET ON THE BACK SIDE OF THIS TROUGH WILL CAUSE IT TO DEEPEN
WITH CYCLOGENESIS OCCURRING OVER THE SOUTHERN PLAINS.

THE MODELS HAVE COME INTO SOMEWHAT BETTER AGREEMENT...ALTHOUGH THE
FINE DETAILS COULD MAKE ALL THE DIFFERENCE.  A SURFACE LOW IS
EXPECTED TO RIDE NE ALONG THE STALLED BOUNDARY AND REACH THE
SOUTHERN GREAT LAKES SUNDAY NIGHT.  THE LOW/S TRACK WILL ULTIMATELY
DECIDE WHERE THE RAIN/SNOW LINE WILL CROSS THE GRR CWA.  PRESENT
INDICATES SUGGEST THE BEST CHANCE FOR ACCUMULATING SNOW WILL BE
NORTH OF I-96...WITH A MESSY MIX ALONG AND SOUTH FOR SUNDAY AND
SUNDAY NIGHT.  THEN AS THE LOW PASSES EAST ALL AREAS SHOULD SEE SOME
SNOW INTO MONDAY AS THE COOLER AIR WRAPS IN.  CERTAINLY A SYSTEM
WORTH WATCHING AND TWEAKS WILL NEED TO BE MADE TO THE FORECAST AS
IT APPROACHES.

OTHERWISE...THE EXTENDED PERIOD LOOKS COOLER WITH ANOTHER CHANCE OF
SNOW AGAIN ON TUESDAY.  THIS LOOKS MINOR HOWEVER AS WE QUICKLY
TRANSITION TO A WARM ADVECTION PATTERN THAT COULD BRING SOME LIGHT
SNOW.
