...Moderate to heavy rain and high elevation snow expected to move into
northern California by tonight...

...More stormy conditions expected to impact the Pacific Northwest with
another  round of rain/snow spreading through the northern Rockies/Great
Basin on Tuesday...

...Threat of strong to severe thunderstorms increasing over the
central/southern Plains later on Wednesday...

Very active and unsettled weather will continue to impact the Pacific
Northwest and northern California as more energetic storm systems from the
Pacific are forecast to move onshore.  A rapidly deepening cyclone located
to the west of British Columbia, Canada will help guide a weaker low
pressure system toward northern California.  The moisture rich environment
ahead of this system will bring a wave of moderate to heavy rain and high
elevation snow into northern California by tonight.  Meanwhile, a strong
cold front associated with the rapidly deepening low will reach the
Pacific Northwest coast early on Tuesday.  Moderate to heavy rain,
mountain snow, rough seas and increasingly strong and gusty winds ahead of
the front will overspread much of the Pacific Northwest tonight into
Tuesday.  The rain/mountain snow will penetrate further inland across the
Great Basin/Intermountain West and then quickly into the northern Rockies
during the day on Tuesday.  The rain/mountain snow is expected to linger
into Wednesday even with the departure of the strong front as an elongated
low pressure system is forecast to form up and down the High Plains on
Wednesday.

The aforementioned elongated low pressure system is forecast to
destabilize the atmosphere across the Plains on Wednesday, with an
increasing threat of strong to severe thunderstorms later that day over
the central/southern Plains where a low pressure wave is forecast to
develop.  A swath of enhanced rainfall can also be expected to move
through the northern Plains on Wednesday ahead of the elongated low
pressure system.

Much of the eastern two-thirds of the country will experience above normal
temperatures during the next couple of days, and especially ahead of the
elongated low pressure system.  Very pleasant autumn weather is expected
to prevail across much of the eastern U.S. for the next couple of days.
Meanwhile, below normal temperatures are expected in parts of the western 
U.S. as well as Florida.
