...HEAVY SNOW POSSIBLE TODAY FOR PORTIONS OF THE NORTHEAST...

...HEAVY RAIN AND MOUNTAIN SNOW POSSIBLE FOR THE PACIFIC
NORTHWEST...

...ABOVE AVERAGE TEMPERATURES EXPECTED FOR THE NORTHERN PLAINS...

LOW PRESSURE ALONG A FRONTAL BOUNDARY OFF THE EAST COAST WILL MOVE
NORTHEASTWARD, GENERALLY PARALLELING THE COAST TODAY. THIS SYSTEM
WILL BRING RAIN, CHANGING TO SNOW, TO PORTIONS OF THE MID-ATLANTIC
THROUGH THIS MORNING, AND ACROSS THE NORTHEAST INTO THIS
AFTERNOON. PORTIONS OF LONG ISLAND AND SOUTHERN NEW ENGLAND WILL
SEE THE POTENTIAL FOR HEAVY SNOWFALL, WITH ACCUMULATIONS OF 4 TO 8
INCHES POSSIBLE. SNOWFALL FROM THIS SYSTEM WILL POTENTIALLY MAKE
THE MORNING COMMUTE DIFFICULT FOR SOME AREAS, AS ROADS MAY BECOME
SNOW COVERED AND SLIPPERY.

A PACIFIC COLD FRONT WILL APPROACH THE NORTHWEST TODAY, SPREADING
RAIN AND MOUNTAIN SNOW INTO THE REGION. RAIN AND SNOW WILL
CONTINUE INTO TONIGHT, BEFORE WINDING DOWN ON SATURDAY AS THE
FRONT QUICKLY MOVES INLAND. THIS SYSTEM WILL PRODUCE LOCALLY HEAVY
RAINFALL AMOUNTS OF 1 TO 3 INCHES, WITH SNOWFALL AMOUNTS UP TO 9
INCHES IN THE WASHINGTON CASCADES.

THE NORTHERN PLAINS AND UPPER GREAT LAKES WILL SEE A COUPLE ROUNDS
OF POTENTIAL PRECIPITATION OVER THE NEXT COUPLE DAYS. A LOW
PRESSURE SYSTEM WILL MOVE EAST ACROSS THE UPPER MIDWEST TODAY,
BRINGING SNOW SHOWERS TO THE REGION, AND MOVING INTO THE UPPER
GREAT LAKES TONIGHT. BY SATURDAY AFTERNOON, THE FRONTAL SYSTEM
THAT WILL AFFECT THE PACIFIC NORTHWEST TODAY WILL BE CROSSING THE
NORTHERN ROCKIES AND MOVING INTO THE NORTHERN PLAINS. THIS SYSTEM
WILL BRING A SCATTERED MIX OF PRECIPITATION TYPES TO THE NORTHERN
PLAINS ON SATURDAY, WITH PRECIPITATION CHANGING TO MOSTLY SNOW
SATURDAY NIGHT ACROSS THE UPPER MIDWEST. IN SPITE OF THESE
PRECIPITATION PRODUCING SYSTEMS, TEMPERATURES WILL GENERALLY BE
ABOVE AVERAGE TODAY AND SATURDAY ACROSS THE NORTHERN PLAINS.
AFTERNOON HIGH TEMPERATURES IN THIS AREA ARE FORECAST TO BE 10 TO
20 DEGREES ABOVE AVERAGE.

A WAVE OF LOW PRESSURE IS FORECAST TO DEVELOP ALONG A STATIONARY
FRONTAL BOUNDARY OVER THE BAHAMAS ON SATURDAY, WHICH IS THEN
FORECAST TO MOVE NORTHEASTWARD INTO SUNDAY. THIS SYSTEM WILL BRING
SHOWERS TO PORTIONS OF THE SOUTHEAST U.S. COASTLINE SATURDAY AND
SUNDAY.
