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

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


THE MAJORITY OF THE COUNTRY WILL ENJOY A RELATIVELY QUIET WEATHER
PATTERN THROUGH SUNDAY AFTERNOON WITH NOT MUCH IN THE WAY OF
ORGANIZED PRECIPITATION.  THE OVERALL FLOW PATTERN WILL BE MORE
ZONAL COMPARED TO RECENT DAYS, THUS PREVENTING ANY SIGNIFICANT
COLD AIR INTRUSIONS FROM CANADA.  IN THE TEMPERATURE DEPARTMENT,
READINGS ARE EXPECTED TO BE ABOVE AVERAGE THROUGH MONDAY ACROSS
MUCH OF THE CENTRAL AND NORTHERN U.S., AND NEAR NORMAL FOR THE
SOUTHEAST AND DEEP SOUTH REGIONS. ACROSS THE NORTHERN PLAINS AND
UPPER MIDWEST, TEMPERATURES ARE FORECAST TO BE 10 TO 20 DEGREES
ABOVE AVERAGE, WITH WIDESPREAD HIGHS IN THE 80S EXPECTED THIS
WEEKEND.

IN TERMS OF PRECIPITATION, SATURDAY WILL BE THE DRIER OF THE TWO
WEEKEND DAYS AS A LARGE AND SPRAWLING SURFACE HIGH OVER MUCH OF
THE CENTRAL AND EASTERN U.S. WILL HELP TO SUPPRESS RAINFALL.  THE
LOW PRESSURE AREA EAST OF THE MID-ATLANTIC REGION IS NOW FAR
ENOUGH OFFSHORE TO KEEP THE EAST COAST DRY.

BY SUNDAY AFTERNOON, MOISTURE IS EXPECTED TO INCREASE ACROSS MUCH
OF THE INTERMOUNTAIN WEST AND GREAT PLAINS.  A COLD FRONT WILL
CONTINUE MOVING SOUTHWARD TOWARD 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, 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.
