...PACIFIC COLD FRONT TO BRING RAIN AND SNOW TO THE WEST COAST FOR
THE BEGINNING OF THE WORK WEEK...

...PERIODS OF WINTRY WEATHER FROM NORTHWEST TEXAS INTO THE MIDWEST
STATES THROUGH TUESDAY...

WEATHER IN THE CENTRAL AND WESTERN U.S. IS GRADUALLY BECOMING MORE
ACTIVE WITH TWO MAIN SYSTEMS.  THE FIRST IS A COLD FRONT MOVING
INTO CALIFORNIA AND OREGON...WHICH WILL BRING PERIODS OF LIGHT TO
MODERATE PRECIPITATION.  THIS WILL GIVE THE SIERRA MOUNTAINS SOME
MUCH NEEDED SNOW.  THE SECOND IS A DEVELOPING LOW AND ASSOCIATED
FRONTAL BOUNDARY OVER THE CENTRAL ROCKIES AND SOUTHERN PLAINS. 
THIS FEATURE WILL GRADUALLY MOVE TO THE EAST AND AFFECT MUCH OF
THE MISSISSIPPI RIVER VALLEY WITH RAIN OVER THE DEEP SOUTH AND
SNOW OVER THE MIDWEST AND EVENTUALLY INTO THE OHIO VALLEY. 
INSTABILITY APPEARS LIMITED...SO THUNDERSTORMS SHOULD BE CONFINED
TO AREAS NEAR THE GULF COAST.

ELSEWHERE OVER THE EASTERN U.S. AND NORTHERN PLAINS...RELATIVELY
QUIET WEATHER CAN BE EXPECTED FOR MONDAY AS TEMPERATURES BEGIN
MODERATING FROM A RECENT COLD SPELL...BEFORE A ROUND OF LIGHT RAIN
AND SNOW BY TUESDAY EVENING FOR THE EAST COAST STATES.
