...MORE QUIET WEATHER IS EXPECTED FOR THE EASTERN U.S. AS
UNSETTLED WEATHER MOVES INTO THE WESTERN U.S...

AFTER A SERIES OF QUICK-MOVING WINTER STORMS, THE EASTERN HALF OF
THE U.S. IS EXPECTED TO ENTER A PERIOD OF QUIETER WEATHER AS A
LARGE HIGH PRESSURE SYSTEM BUILDS IN FROM THE NORTHERN PLAINS AND
INTO THE ENTIRE EASTERN U.S. BY SATURDAY.  ARCTIC AIR WILL
ACCOMPANY THIS HIGH PRESSURE SYSTEM WHERE TEMPERATURES OF 10 TO 30
DEGREES BELOW NORMAL WILL BE WIDESPREAD.  THE ONLY AREAS SEEING
PRECIPITATION WILL BE IN SOUTHERN FLORIDA WHERE SHOWERS AND
THUNDERSTORMS ARE EXPECTED BEHIND A COLD FRONT.  ANOTHER AREA OF
PRECIPITATION WILL BE FROM THE OHIO VALLEY INTO THE CENTRAL
APPALACHIANS WHERE SNOW SHOWERS SHOULD INITIALLY ACCOMPANY A
DISSIPATING COLD FRONT.

MEANWHILE, THE WEST CONTINUES TO ENJOY NEAR TO ABOVE NORMAL
TEMPERATURES.  HOWEVER, AN UPPER-LEVEL SHORTWAVE TROUGH IS
BEGINNING TO DIG SOUTHWARD FROM THE GULF OF ALASKA.  THIS TROUGH
IS EXPECTED TO BRING INCREASING MOISTURE AS WELL AS COLDER AIR
INTO THE PACIFIC NORTHWEST FRIDAY AND INTO SATURDAY. WE CAN EXPECT
RAIN NEAR THE COAST WILL BEGIN TO SPREAD STEADILY TO THE SOUTH AND
EAST INTO THE INTERIOR MOUNTAINS AS SNOW FRIDAY INTO SATURDAY.
OVER THE CENTRAL ROCKIES, UPSLOPE FLOW CONTINUES TO SUPPORT SNOW
IN WESTERN COLORADO INTO NEW MEXICO.  UPPER-LEVEL WINDS ARE
EXPECTED TO PUSH TO MOISTURE SOUTHEASTWARD INTO THE CENTRAL AND
SOUTHERN PLAINS WHERE LIGHT SNOW IS EXPECTED OVER THE PANHANDLES
OF TEXAS AND OKLAHOMA ON FRIDAY.  BY FRIDAY NIGHT INTO SATURDAY
MORNING, WE COULD BE LOOKING AT SLEET AND FREEZING RAIN FORMING IN
CENTRAL TEXAS.  RAIN SHOWERS ARE ALSO EXPECTED TO FORM DOWN INTO
SOUTHERN TEXAS.
