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.
