...Increasingly stormy conditions expected to impact the Pacific Northwest
to the northern Plains for the next couple of days as a deep low pressure
system moves onshore...

...Heavy rain and severe thunderstorm threat expand across the Deep South
for the next couple of days before moving up the East Coast Tuesday
night/Wednesday morning...

...Critical Fire Weather Risk will persist over the northern High Plains...

A potent low pressure system will bring increasingly active weather
swiftly through the western U.S. and then across the Plains during the
next couple of days.  Abundant moisture ahead of this system is already
streaming onshore into the Pacific Northwest and will continue to
penetrate further inland.  Moderate to heavy rain and scattered
thunderstorms  near the coast will be accompanied by strong and gusty
winds today.  Meanwhile, heavy snow will break out along the Cascades
before expanding into the northern Rockies later today together with high
winds.  Heavy snow will be measured in feet over the northern Cascades
before the snow tapers off Tuesday night.  As this system forces its way
through the northern Rockies into the northern High Plains, widespread
high winds are expected to impact through these area and especially the
foothills later today and through Tuesday before gradually tapering of by
Wednesday.  The high winds will be accompanied with periods of mixed rain
and snow as the system reorganizes and expands over the northern Plains. 
Farther south, showers and thunderstorms are expected to develop ahead of
an intensifying cold front later on Tuesday as it sweeps across the upper
Midwest.  The thunderstorms could intensify further as they reach the
western portion of the Great Lakes by Wednesday morning with strong and
gusty winds.

Meanwhile across New England, a rapidly intensifying low pressure system
moving off the coast will manage to rotate some mixed rain/snow especially
across Downeast Maine this morning with gusty northwesterly winds.  This
system will move away by tonight with clearing skies and diminishing winds.

Farther south, the thunderstorm threat will remain suppressed across
southern Florida for the next couple of days as a cold front becomes
nearly stationary.  Moisture from the Gulf of Mexico will begin to surge
north toward the southern tier states and converge with the cold front
slowly moving into the southern Plains.  This will lead to a steady
expansion of showers and thunderstorms from the southern Plains into the
Deep South over the next couple of days.  The rain and storms are expected
to intensify as they reach into the Deep South later Monday into Tuesday
with the possibility of flash flooding and severe weather.  By Tuesday
night, the rain will likely spread into the eastern U.S. with the highest
threat of heavy rain and severe thunderstorms moving across the Southeast.
 A compact low pressure system is forecast to intensify near the Carolina
coast by Wednesday morning with a period of enhanced rainfall and gusty
winds near its track.
