...MORE SNOW FOR THE WESTERN U.S. AND GREAT LAKES, AND RAIN
RETURNS TO THE GULF COAST REGION...

NOW THAT THE STRONG COLD FRONT HAS CLEARED THE EAST COAST, EXPECT
A RETURN TO TEMPERATURES THAT ARE MORE TYPICAL OF FEBRUARY,
COMPARED TO THE PAST FEW DAYS THAT WERE A PREVIEW OF SPRING.  A
SURFACE HIGH PRESSURE AREA WILL SETTLE IN BEHIND THE FRONT ACROSS
THE EASTERN U.S., AND IT WILL BE ACCOMPANIED BY SUNNY TO PARTLY
CLOUDY SKIES ALONG WITH TEMPERATURES MAINLY IN THE 40S AND 50S ON
SUNDAY AFTERNOON.  THE EXCEPTION TO THIS WILL BE THE GREAT LAKES
REGION, WHERE A WEAK IMPULSE CROSSING OVERHEAD WILL BE ENOUGH TO
GENERATE PERIODS OF SNOW SHOWERS FROM NORTHERN MINNESOTA TO
UPSTATE NEW YORK.

BY MONDAY MORNING, RETURN FLOW FROM THE GULF OF MEXICO AHEAD OF
THE NEXT STORM SYSTEM OVER TEXAS WILL BEGIN ADVECTING INCREASED
MOISTURE NORTHBOUND ACROSS MUCH OF THE SOUTHERN PLAINS AND THE
DEEP SOUTH.  NUMEROUS SHOWERS AND STORMS ARE LIKELY TO DEVELOP
DURING THE FIRST HALF OF THE WORK WEEK AS THE WARM FRONT LIFTS
NORTHWARD, WITH SOME LOCATIONS GETTING IN EXCESS OF AN INCH OF
RAINFALL BY TUESDAY MORNING, ESPECIALLY FROM SOUTHERN ARKANSAS TO
NORTHERN ALABAMA.

ACROSS THE NORTHWESTERN QUADRANT OF THE NATION, A DEVELOPING LOW
PRESSURE SYSTEM AND ACCOMPANYING UPPER LEVEL DISTURBANCE WILL
BRING MORE WIDESPREAD COVERAGE OF COASTAL RAIN AND MOUNTAIN/INLAND
SNOW SHOWERS FOR SUNDAY.  MORE OF THE INTERMOUNTAIN WEST WILL
LIKELY BE AFFECTED GOING INTO MONDAY AS THE FRONTAL BOUNDARY MOVES
FARTHER INLAND.  HEAVY SNOW IS LIKELY FOR THE HIGHER MOUNTAIN
RANGES.
