...A WINTER STORM IS LIKELY MONDAY NIGHT AND TUESDAY...

LOW PRESSURE WILL DEVELOP OVER THE GULF OF MEXICO TODAY. ALTHOUGH
THE EXACT TRACK AND STRENGTH OF THIS STORM REMAINS UNCERTAIN, A
POSITION OVER CENTRAL OR EASTERN PENNSYLVANIA IS EXPECTED
BY TUESDAY AFTERNOON. THE EXACT TRACK OF THIS STORM WILL HAVE
MAJOR IMPLICATIONS FOR PRECIPITATION TYPE AND AMOUNTS ACROSS CENTRAL
NEW YORK AND NORTHEAST PENNSYLVANIA ON MONDAY NIGHT AND TUESDAY.

AT THE PRESENT TIME, THE MOST LIKELY SCENARIO CALLS FOR RAIN
TO SPREAD ACROSS THE REGION ON CHRISTMAS AFTERNOON. ON MONDAY NIGHT,
A MIX OF RAIN AND SNOW IS EXPECTED ACROSS UPSTATE NEW YORK,
WITH THE POTENTIAL FOR MODERATE SNOW ACCUMULATIONS OVER THE HIGHER
ELEVATIONS. THE PRECIPITATION SHOULD BE PRIMARILY IN THE FORM OF RAIN
ACROSS NORTHEAST PENNSYLVANIA ON MONDAY NIGHT.

AS THE LOW MOVES INTO NEW ENGLAND ON TUESDAY AFTERNOON, A COLDER
NORTHWEST FLOW WILL DEVELOP, CHANGING ALL OF THE PRECIPITATION OVER
TO SNOW. THE CHANGEOVER TO SNOW WOULD LIKELY OCCUR DURING THE
EARLY MORNING HOURS ACROSS UPSTATE NEW YORK, AND DURING THE AFTERNOON
ACROSS NORTHEAST PENNSYLVANIA. CURRENTLY, THE GREATEST SNOW
ACCUMULATIONS APPEAR MOST LIKELY ON TUESDAY OVER PORTIONS OF THE
FINGER LAKES AND CENTRAL SOUTHERN TIER OF NEW YORK, WITH POTENTIAL
AMOUNTS OF 6 TO 10 INCHES.

TRAVEL MAY BECOME DIFFICULT ON CHRISTMAS NIGHT, AND THE HAZARDOUS
DRIVING CONDITIONS WILL LIKELY WORSEN ON TUESDAY.

THE NATIONAL WEATHER SERVICE WILL CONTINUE TO MONITOR DEVELOPMENTS
CLOSELY.
