SHORT RANGE FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
348 AM EDT MON SEP 22 2014

VALID 12Z MON SEP 22 2014 - 12Z WED SEP 24 2014


THE WEATHER PATTERN ACROSS THE UNITED STATES WILL BE CALMING DOWN
A BIT DURING THE NEXT FEW DAYS FROM THE VERY ACTIVE REGIME OF
LATE. THE HEAVY RAINFALL OVER THE SOUTHWEST--LARGELY FUELED BY THE
REMNANT MOISTURE FROM LONG-SINCE SPUN-DOWN TROPICAL CYCLONE
ODILE--IS EXPECTED TO SLOWLY SUBSIDE AS A VIGOROUS AUTUMNAL STORM
BEARS DOWN ON THE PACIFIC NORTHWEST. MOST OF THE WIND AND
PRECIPITATION WITH THAT CYCLONE SHOULD REMAIN OFFSHORE DURING THE
NEXT COUPLE OF DAYS, BUT THE UPPER-LEVEL JET STREAM ASSOCIATED
WITH IT WILL SET FUNDAMENTAL CHANGES INTO MOTION ACROSS MUCH OF
THE NATION. FLORIDA AND THE IMMEDIATE SOUTHEASTERN ATLANTIC COAST
WILL BE ON THE WET SIDE AS A WAVE OF LOW PRESSURE RIPPLES ALONG A
STATIONARY FRONT JUST OFFSHORE. THE GREAT LAKES, OHIO RIVER
VALLEY, NORTHEAST, AND MID-ATLANTIC STATES WILL EXPERIENCE A SHARP
COOLDOWN IN THE WAKE OF THE TWO AREAS OF LOW PRESSURE CROSSING THE
CANADIAN MARITIME PROVINCES.
