...Flooding rains possible through early Saturday morning for portions of
coastal southern California...
...Significant winter storm possible over the holiday weekend from the
Rockies to portions of the northern plains and Upper Midwest...
...Above average temperatures expected for much of the central and eastern
U.S...
Much of the U.S. will be impacted this holiday weekend by a robust winter
storm system that will track across the Rockies and through the Plains
states into the Upper Midwest and Great Lakes region. Widespread rain,
heavy at times, has been observed overnight across portions of southern
California as the front moved inland. Rain and the threat for flash
flooding will linger into the morning hours. Widespread snow will spread
into the Great Basin, Intermountain West, and the Rockies today and into
the northern High Plains by late afternoon/evening. Heavy snow will be
possible, especially at the higher elevations of the West. Rain is
expected to fall at the lower elevations in the Southwest and Four Corners
regions. Most counties west of the continental Divide and across eastern
Montana have winter weather advisories and winter storm warnings in
effect. Most of the Dakotas have blizzard warnings in effect.
Once the system exits the Rockies and moves out over the Plains, the
surface low will quickly deepen. Strong winds, possibly in excess of 60
mph, will cause snow to blow and drift, making travel hazardous -
especially across the northern-tier states. Please refer to products
issued by local NWS Forecast Offices for details specific to your area.
Thunderstorms will be possible along and ahead of the front moving through
the central Plains on Sunday and Monday. Some thunderstorms could be
severe - please refer to products issued by the Storm Prediction Center
for further details on the severe weather threat.
Areas of snow and mixed precipitation is possible from the Great Lakes to
the Northeast, with rain and a few thunderstorms from the
lower/mid-Mississippi valley to the Mid-Atlantic today. Once the weakening
system passes through temperatures will warm up across the central and
eastern states. Afternoon high temperatures are forecast to be 5 to 15
degrees above average on today. By Sunday, as warmer air is pulled north
across the plains ahead of the rapidly deepening cyclone, high
temperatures may reach 15 or more degrees above average for many areas of
the plains, Ohio and Tennessee valleys, and the Southeast.
