...Major winter storm for California Wednesday and Thursday...
...Cold across the northern tier of the nation with a winter storm
developing later this week and into the weekend...
As a large system approaches California and moves inland, a major winter
storm will develop especially across the Sierra Nevada. Blizzard
conditions will be possible especially over 6500 feet with 2 to 4 feet,
with 6 feet of snow expected in the peaks, of snow expected in this
mountain range. Blizzard warnings have been issued and will be in effect
through Thursday afternoon--with winter storm warnings for areas above
5500 feet being in effect through Friday morning. In addition to the heavy
snow, heavy rain will also impact along the coast of California. Most of
this rainfall will occur through tomorrow evening. A moderate risk of
rainfall has been issued for a small area in southern California
particularly where the burn scars are in the Los Angeles region.
Precipitation will begin to wind down by Thursday night and into Friday
morning as the frontal system progresses farther inland.
Unsettled weather may bring a possible winter storm tracking from the
Midwest to the Northeast Friday through Sunday. In the stormâ€s wake,
bitter cold temperatures will overtake a large part of the central and
eastern U.S. In fact, the northern Plains will have high temperatures
staying below zero on Friday--which is nearly 25 degrees below normal!
Freezing rain, heavy snow, along with heavy rain is expected along its
path through the central and eastern U.S. over the weekend. Heavy snow
will begin by Friday evening in the central Plains and progress eastward
by the weekend. See WPC's winter weather products and discussion for more
information on this system.
