NORTHERN MID-ATLANTIC...

THE SOUTHEAST...

SNOW IS EXPECTED FOR PORTIONS OF THE GREAT LAKES, OHIO VALLEY,
CENTRAL AND SOUTHERN APPALACHIANS AND ACROSS PARTS OF THE NORTHERN
MID-ATLANTIC. ENERGY ROTATING AROUND THE UPPER LOW WILL AID IN
PRODUCING PRECIPITATION. NUMEROUS WINTER WEATHER ADVISORIES AND
WINTER STORM WARNINGS ARE IN EFFECT ACROSS THIS REGION.
ACCUMULATIONS OF 1 TO 6 INCHES WILL BE COMMON. THE GREAT LAKES AND
AREAS JUST DOWNWIND WILL LIKELY HAVE 6 TO 12+ INCHES. RAIN WILL
DEVELOP OVER PARTS OF THE SOUTHERN MID-ATLANTIC COAST THROUGH
WEDNESDAY MORNING.

COLD AIR WILL SETTLE OVER MUCH OF THE EASTERN STATES. TEMPERATURES
ARE FORECAST TO BE 10 TO 20 DEGREES BELOW AVERAGE OVER THE
UPPER/MIDDLE MISSISSIPPI VALLEY INTO PARTS OF THE OHIO VALLEY AND
THE SOUTHEAST.

LOW PRESSURE WILL SLIDE SOUTHEASTWARD FROM THE CANADIAN PRAIRIES
INTO THE PLAINS STATES. SNOW IS EXPECTED ACROSS THE HIGH PLAINS
THE UPPER AND MIDDLE MISSISSIPPI VALLEY. SNOW ACCUMULATIONS WILL
GENERALLY BE ON LESS THAN 4 INCHES. ISOLATED AMOUNTS NEAR 6 INCHES
MAY BE POSSIBLE.

THE PACIFIC NORTHWEST WILL BE WET OVER THE NEXT COUPLE OF DAYS AS
A FRONT APPROACHES THE COAST. A STRONG RIDGE WILL BE IN PLACE
ACROSS MUCH OF THE WEST, RESULTING IN VERY HIGH SNOW LEVELS.
MOUNTAIN SNOW WILL LIKELY BE MINIMAL, WITH THE BULK OF THE
PRECIPITATION FALLING AS RAIN ALONG THE WASHINGTON, OREGON AND
NORTHERN CALIFORNIA COASTAL AREAS. NORTHWEST WASHINGTON AND
VANCOUVER ISLAND COULD SEE RAINFALL AMOUNTS TOTALING UP TO 4.5
INCHES BY FRIDAY EVENING.
