***WARM WEATHER PATTERN ACROSS MUCH OF THE COUNTRY THROUGH
MONDAY***

***PRECIPITATION TO BECOME MORE WIDESPREAD BY SUNDAY NIGHT AND
MONDAY***


THE EASTERN THIRD OF THE COUNTRY WILL ENJOY A RELATIVELY QUIET
WEATHER PATTERN THROUGH MONDAY AFTERNOON WITH NOT MUCH IN THE WAY
OF ORGANIZED PRECIPITATION.  A SURFACE HIGH OVER THE WESTERN
ATLANTIC WILL EXTEND WESTWARD FROM THE EAST COAST TO THE DEEP
SOUTH, THUS KEEPING SKY CONDITIONS SUNNY TO PARTLY CLOUDY.  IN THE
TEMPERATURE DEPARTMENT, HIGHS ARE FORECAST BE 10 TO 20 DEGREES
ABOVE AVERAGE ACROSS MUCH OF THE MID-ATLANTIC AND NORTHEAST ON
MONDAY.  THIS WILL ALSO BE THE CASE FOR THE CENTRAL PLAINS AND
MIDWEST STATES, WITH WIDESPREAD TEMPERATURES IN THE 80S EXPECTED.

MOISTURE HAS STARTED TO INCREASE ACROSS MUCH OF THE INTERMOUNTAIN
WEST AND GREAT PLAINS.  A COLD FRONT WILL CONTINUE MOVING
SOUTHWARD THROUGH THE GREAT BASIN THIS EVENING AND SHOULD BECOME
NEARLY STATIONARY TONIGHT INTO SUNDAY.  THIS BOUNDARY WILL SERVE
AS A FOCUS FOR SHOWERS AND THUNDERSTORMS ACROSS THE FOUR CORNERS
REGION AND THE ROCKY MOUNTAINS FOR THE BEGINNING OF THE WEEK, AND
MUCH OF THIS ACTIVITY WILL BE DIURNALLY AND OROGRAPHICALLY
ENHANCED.  ANOTHER FRONT CROSSING THE NORTHERN PLAINS AND UPPER
MIDWEST WILL ALSO RESULT IN A BAND OF SHOWERS AND STORMS AS
MOISTURE GETS DRAWN NORTHWARD INTO THIS SYSTEM.  BY TUESDAY, MORE
SHOWERS AND STORMS ARE EXPECTED TO DEVELOP FROM THE CENTRAL PLAINS
TO THE OHIO VALLEY, AND SOME OF THESE STORMS COULD BECOME SEVERE
AT TIMES.
