...SHARPLY FALLING TEMPERATURES IN THE NORTH-CENTRAL U.S. WITH
10-20 DEGREE DEPARTURES FROM AVERAGE HIGHS BY TUESDAY...

...UNSETTLED CONDITIONS WITH COLDER TEMPERATURES AND SNOW FROM THE
OHIO VALLEY INTO THE NORTHERN MID-ATLANTIC AND NORTHEAST TO START
OFF THE WEEK...

...WARM AND DRY ALONG THE WEST COAST THROUGH MID-WEEK...

A RAPIDLY STRENGTHENING SURFACE LOW OFF OF THE SOUTHEAST U.S.
COASTLINE WILL LIFT NORTHEASTWARD TONIGHT, FAR ENOUGH AWAY FROM
LAND TO LARGELY SPARE NEW ENGLAND FROM A MAJOR SNOW STORM. STILL,
SOUTHEASTERN NEW ENGLAND WILL LIE CLOSE ENOUGH TO THE OUTER EDGES
OF THE STORM SYSTEM AND COULD PICK UP SEVERAL INCHES OF SNOW
DURING THE DAY ON MONDAY, WITH THE HEAVIEST OVER SOUTHEASTERN
MASSACHUSETTS, WHERE 6 OR MORE INCHES COULD FALL THROUGH MONDAY
EVENING.

A SECOND STORM SYSTEM IS CURRENTLY PRODUCING BLIZZARD-LIKE
CONDITIONS THROUGHOUT PORTIONS OF THE LOWER NORTHERN PLAINS AND
MINNESOTA. WHILE SNOW ACCUMULATIONS ARE LIGHT, THE STORM IS
USHERING IN FRIGID TEMPERATURES FROM THE NORTH WITH WINDS GUSTING
TO 40 AND 50 MPH. A DEVELOPING UPPER LEVEL TROUGH OVER THE REGION
WILL GRADUALLY INCREASE IN SIZE AS IT SETTLES OVER THE EASTERN
HALF OF THE NATION BY TUESDAY MORNING. UNSETTLED CONDITIONS ARE
EXPECTED FOR MANY FROM THE OHIO VALLEY TO THE NORTHEAST WITH
SCATTERED SNOW SHOWERS AND THE DEVELOPMENT OF A SECONDARY AREA OF
LOW PRESSURE NEAR THE MID-ATLANTIC COAST EARLY TUESDAY MORNING.
EXCEPT ALONG THE IMMEDIATE COAST, TEMPERATURES WILL BE COLD ENOUGH
TO SUPPORT SNOW WITH MOSTLY LIGHT ACCUMULATIONS, THOUGH SOME
MODERATE ACCUMULATIONS IN EXCESS OF 4-6 INCHES WILL BE POSSIBLE
FOR A FEW LOCATIONS IN THE NORTHERN MID-ATLANTIC REGION.

HIGH PRESSURE WILL REMAIN WEST OF THE ROCKIES THROUGH AT LEAST
WEDNESDAY, WHICH WILL KEEP DRY CONDITIONS IN PLACE. TEMPERATURES
ARE EXPECTED TO BE ROUGHLY 10 TO 20 DEGREES ABOVE AVERAGE WITH
LIMITED CLOUD COVER FROM WASHINGTON TO CALIFORNIA. A COLD FRONT IS
EXPECTED TO NEAR THE WEST COAST LATE TUESDAY INTO WEDNESDAY WHICH
WILL INCREASE CLOUDS ALONG COASTAL LOCATIONS, BUT ANY CHANCE FOR
RAINFALL WILL HOLD OFF TIL LATE IN THE DAY WEDNESDAY AND BE
LIMITED TO THE PACIFIC NORTHWEST COAST.
