...Developing storm to have widespread impacts over the next few days
across large areas to the east of the Mississippi River...

...Much more tranquil weather on tap for the western half of the nation...


A developing storm across the western Gulf coast Tuesday afternoon will be
pushing northeastward tonight into the Lower Mississippi Valley, through
the Ohio Valley and Lower Lakes on Wednesday and into the Northeast by
early Thursday.  This storm will be multi faceted and have significant
impacts across a large portion of the nation from the Gulf coast into the
Northeast.  A well defined area of precipitation Tuesday afternoon over
the Southern Plains will be expanding northeastward with time.  Heavy
rains, isolated flash flooding and severe thunderstorms are possible
across portions of the western to central Gulf coast from Tuesday
afternoon into Tuesday night, spreading into the eastern Gulf coast and
Southeast during Wednesday.  Heavy rains are also possible Wednesday into
early Thursday across the major urban corridor from Richmond, DC,
Baltimore, Philadelphia, NYC into Boston.


On the north and northwest side of this storm, heavy snows are likely from
northwest Texas across much of Oklahoma into northern Arkansas, Southern
Missouri and southern Illinois from Tuesday afternoon into Tuesday
night/early Wednesday.  This heavy snow potential will then push
northeastward across portions of the Mid-West, Lower Lakes, northern
Mid-Atlantic, Western/ Upstate/ Northern NY State and northern New England
from Wednesday into early Thursday.  Across all of these areas, winter
storm warnings, advisories and watches are currently in effect. 
Widespread snowfall accumulations of 4 to 8"+ expected across these areas,
with locations in northern New England having the potential for
accumulations of 8 to 12".  The expected snowfall will have moderate to
major impacts from the Southern Plains into the Mid Mississippi Valley,
Mid West, portions of northern NY State into northern New England with
snow covered roads, reduced visibility resulting in dangerous traveling
conditions.  In addition, the combination of the heavy snow and gusty
winds may result in downed trees and power outages. This snowfall will
bring some relief from the "snow drought" for portions of the Mid-West,
northern Mid-Atlantic, New York State and central to northern New England
where snowfall totals this season are well below average.

Tranquil weather on tap for much of the western U.S. from the High Plains,
across the Rockies and into the West Coast.  Much of this region will be
dry over the next few days, save for some light to locally moderate
snowfall amounts through the Rockies and across the Northern Plains. No
signs of any additional precipitation for water soaked area of California
through the remainder of this week.
