The winter storm that prompted widespread blizzard warnings across the
northern and central Plains will continue to gradually wind down today. 
Nevertheless, the huge circulation in connection with this anomalous low
pressure system will take some time to spin down.  The main swath of snow
that is still impacting portions of the northern Plains to the central
High Plains this morning is forecast to taper off to light snow by
tonight.  An area of mixed rain and snow will accompany the weakening low
pressure center through Missouri today.  By Thursday into Friday morning,
the mixed rain/snow will move into the Midwest and then linger or even
expand a bit over the Midwest when another piece of energy from the north
is forecast to interact with the low pressure system.

Meanwhile on the eastern periphery of the huge system where mild Atlantic
air attempts to overrun the cool ground inland from the Atlantic coast, a
round of rain is forecast to move up the East Coast as a low pressure
system begins to develop today into tonight.  Some embedded thunderstorms
are possible over the Mid-Atlantic this morning.  By Thursday morning, the
low center should be passing just off the southern New England coast where
an area of enhanced rainfall is forecast across New Jersey to Long Island.
 As the low moves off the coast later on Thursday, residual energy from
the weakening storm over the Midwest will keep a chance of showers across
much off the Northeast into Friday morning, with light wintry mix possible
over Maine.

Across Florida, a round of rain is forecast to pass southern Florida as an
upper-level disturbance moves across the region.

Meanwhile, moisture well ahead of a couple of large Pacific cyclones is
forecast to keep weather unsettled along the West Coast for the next
couple of days. These systems will produce rain and highest elevation snow
over the Pacific Northwest and California while much of the reminder of
the western U.S. will remain dry under the protection of a stable high
pressure system.
