Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 205 PM EDT Mon Sep 22 2014 Valid 00Z Tue Sep 23 2014 - 00Z Thu Sep 25 2014 The heavy rainfall over the southern Rockies--largely fueled by the remnant moisture from long-since spun-down tropical cyclone Odile--is expected to slowly subside as upper level energy moving through the northern Plains lures its moisture piecemeal to the northeast into the central Plains, causing thunderstorms with periods of heavy rain tonight and Tuesday night. A vigorous autumnal storm bears down on the Pacific Northwest late Tuesday into Wednesday, bringing an end to the Pacific Northwest's sunny conditions and breeze conditions on Tuesday in advance of its cold front. Showers and thunderstorms with heavy rainfall will surge inland Tuesday night into Wednesday morning before slowly subsiding thereafter. The highest winds from the system should remain offshore the Pacific Northwest and along the coast of western British Columbia and Vancouver Island. Florida and the immediate southeast coast will be wet as a weak wave of low pressure and its attendant coastal trough focuses thunderstorms with potentially heavy rainfall to the east of a bundle of upper level energy sliding into Georgia and the Carolinas. Elsewhere, the Great Lakes, Ohio River valley, Northeast, and Mid-Atlantic states will be seasonably cool under the aegis of strong high pressure with crisp mornings -- freezing temperatures are expected in New England -- and cool to mild afternoons expected through Wednesday. High sea level pressure records for the month of September could be tied or broken across portions of New England on Wednesday morning. Roth/Cisco Graphics available at
