SHORT RANGE FORECAST DISCUSSION
NWS HYDROMETEOROLOGICAL PREDICTION CENTER CAMP SPRINGS MD
422 AM EDT WED AUG 27 2008
VALID 12Z WED AUG 27 2008 - 00Z FRI AUG 29 2008
THE REMNANTS OF FAY HAVE MOVED INTO THE MID-ATLANTIC REGION AND
WILL SLOWLY PUSH NORTH-NORTHEASTWARD...YIELDING MODERATE TO HEAVY
PRECIPITATION ALONG THE WAY. THE THREAT OF FLOODING WILL STILL BE
AN ISSUE...ESPECIALLY ALONG THE EASTWARD SPINE OF THE APPALACHIANS
WHERE OROGRAPHIC ENHANCEMENT MAY OCCUR. MID-LEVEL ENERGY
ASSOCIATED WITH FAY WILL LINGER THROUGHOUT THIS FORECAST PERIOD
BEFORE EVENTUALLY GETTING ABSORBED INTO THE LONGWAVE TROUGH.
MEANWHILE... A WEAK FRONT THAT IS CURRENTLY OVER THE CANADIAN
PRAIRIE AND UPPER MISSISSIPPI VALLEY WILL SERVE AS AN EFFICIENT
LIFTING MECHANISM...ENABLING CONVECTION TO GET BETTER ORGANIZED.
BY THURSDAY...A SECOND SURGE OF ENERGY WILL MOVE INTO THE NORTHERN
PLAINS...RE-ENERGIZING THE AFOREMENTIONED COLD FRONT. HEADING
WEST...A PACIFIC CYCLONE THAT IS OFF THE COAST OF BRITISH COLUMBIA
WILL MOVE INLAND WEDNESDAY AND BY THURSDAY MORNING A SECOND SYSTEM
WILL BE WITHIN STRIKING DISTANCE OF BRITISH COLUMBIA. THE NET
RESULT OF THESE TWO STORMS WILL BE REASONABLE AMOUNTS OF
PRECIPITATION FOR BRITISH COLUMBIA...AND SUBSTANTIALLY LESS
ACTIVITY FOR THE PACIFIC NORTHWEST...ALTHOUGH PORTIONS OF
WASHINGTON STATE AND MONTANA CAN ANTICIPATE SCATTERED SHOWERS.
