SHORT RANGE FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
431 AM EDT TUE SEP 23 2014

VALID 12Z TUE SEP 23 2014 - 12Z THU SEP 25 2014


THE BIG WEATHER FEATURE AFFECTING THE UNITED STATES DURING THE
NEXT FEW DAYS WILL BE THE SPRAWLING CYCLONE BEARING DOWN ON THE
PACIFIC NORTHWEST COAST. THIS GIANT STORM IS EXPECTED TO LASH THE
COASTLINE WITH STRONG WINDS AND WAVES, WITH HEAVY RAINS SPREADING
INLAND TO THE CREST OF THE CASCADES. THE ATTENDANT COLD FRONT
SHOULD SLICE INTO MUCH OF COASTAL CALIFORNIA, WITH SIGNIFICANT
SHOWERS REACHING ALL THE WAY TO THE SAN FRANCISCO BAY AREA. THE
CENTRAL STATES WILL SLOWLY DRY OUT, THOUGH WEAK DISTURBANCES
SHOULD KEEP THE THREAT OF AT LEAST SCATTERED SHOWERS THROUGH
THURSDAY. A LARGE, COOL CANADIAN HIGH WILL SETTLE THROUGH MUCH OF
THE EAST, SAVE THE COASTAL SOUTHEAST AND MID ATLANTIC WHERE A WAVE
OF LOW PRESSURE JUST OFFSHORE SPREADS A SHIELD OF SHOWERS OVER
MUCH OF THE COASTAL PLAIN.
