VALID 12Z TUE AUG 25 2009 - 00Z THU AUG 27 2009
 
DRIER MORE SETTLED CONDITIONS ARE EXPECTED ACROSS MUCH OF THE
LOWER 48 OVER THE SHORT-TERM.  THE MAIN EXPECTION WILL BE ALONG
THE COLD FRONT THAT CURRENTLY EXTENDS FROM THE UPPER MISSISSIPPI
VALLEY SOUTHWESTWARD BACK INTO THE CENTRAL PLAINS.  SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO FIRE ALONG THIS BOUNDARY AS IT MOVES
SOUTH AND EAST WITH TIME.  THESE STORMS SHOULD BE MAINLY SCATTERED
IN NATURE WITH PERHAPS SOME MORE ORGANIZED ACTIVITY DEVELOPING
LATER TODAY OVER THE CENTRAL PLAINS AND MID MISSISSIPPI VALLEY IN
RESPONSE TO A STRING OF UPPER LEVEL DISTURBANCES MOVING OUT OF THE
WESTERN U.S.  FURTHER TO THE EAST...SCATTERED SHOWERES AND
THUNDERSTORMS ARE EXPECTED AS WELL ALONG THE SOUTHERN MID ATLANTIC
AND SOUTHEAST COASTS AS A WEAK FRONTAL BOUNDARY REMAINS IN PLACE. 
AND FINALLY...SOME SCATTERED LIGHT RAINS ARE POSSIBLE ACROSS PARTS
OF WESTERN WASHINGTON AND OREGON BEHIND A FRONTAL BOUNDARY MOVING
THROUGH THE NORTHWESTERN U.S.  ELSEWHERE AGAIN...HIGH PRESSIRE AND
DRY CONDITIONS ARE EXPECTED TO PREVAIL OVER THE NEXT COUPLE OF
DAYS.
