...MORE SNOW FOR THE WESTERN U.S., AND RAIN AND THUNDERSTORMS
RETURN TO THE GULF COAST AND MUCH OF THE SOUTHEASTERN U.S....

WITH THE SURFACE HIGH PRESSURE AREA NOW MOVING OFF THE EAST COAST,
EXPECT A GRADUAL WARMING TREND ALONG WITH INCREASING MOISTURE
GOING INTO THE MIDDLE OF THE WEEK FOR THE EASTERN U.S.  RETURN
FLOW FROM THE GULF OF MEXICO AHEAD OF THE NEXT STORM SYSTEM OVER
TEXAS IS ADVECTING ENOUGH HUMIDITY NORTHWARD TO GENERATE SHOWERS
AND SCATTERED THUNDERSTORMS EXTENDING FROM TEXAS TO THE DEEP
SOUTH, AND THIS WILL CONTINUE ON MONDAY.

MORE WIDESPREAD SHOWERS AND STORMS ARE LIKELY TO DEVELOP BY
TUESDAY AND GOING INTO WEDNESDAY AS THE WARM FRONT CONTINUES
LIFTING NORTHWARD.  SOME LOCATIONS COULD EASILY GET IN EXCESS OF
AN INCH OF RAINFALL BY TUESDAY MORNING, ESPECIALLY ACROSS PARTS OF
THE LOWER MISSISSIPPI RIVER VALLEY.  SEVERE THUNDERSTORMS WILL BE
POSSIBLE ON TUESDAY FROM ARKANSAS TO THE OHIO VALLEY AHEAD OF THE
DEVELOPING STORM SYSTEM OVER THE CENTRAL PLAINS.  WINDY CONDITIONS
ARE EXPECTED TO DEVELOP OVER WESTERN TEXAS AND EASTERN MEXICO,
WHERE HIGH WIND WATCHES ARE IN EFFECT.

SNOW WILL CONTINUE TO BE IN THE FORECAST FOR THE MOUNTAINS OF THE
WESTERN U.S. FOR THE FIRST HALF OF THE WORK WEEK.  THE CASCADES,
SIERRA, WASATCH, AND CENTRAL/SOUTHERN ROCKIES SHOULD SEE THE
GREATEST SNOWFALL TOTALS, WITH SOME LOCATIONS GETTING IN EXCESS OF
A FOOT OF ADDITIONAL SNOWFALL.  RAIN IS LIKELY FOR THE LOWER
ELEVATIONS OF THE DESERT SOUTHWEST AND THE COASTAL PACIFIC
NORTHWEST.
