...There remains a Slight Risk of Excessive Rainfall over parts of
Southern California and a Marginal Risk for flash flooding for
northern California on Friday...

...Accumulating ice and heavy snow possible for the Upper Midwest
to the Northeast tomorrow...

...Record warmth hangs around for the southern Plains to the
Tennessee Valley...

Bands of heavy rainfall continue to move across California ahead
of another developing area of low pressure in the Pacific. Expect
this to continue though the afternoon and into tomorrow as energy
from the upper trough sweeps through the area. Hazards of flash
flooding, strong winds and severe weather chances, and heavy snow
in the high terrain of central and northern California are likely.
There is light at the end of the tunnel as the surface cold front
looks to clear the area late Friday and bring much appreciated
improving weather conditions on Saturday and Sunday. Please listen
to emergency officials, stay tuned to local warnings, and have a
safe holiday.

The northern tier of the country will see snow and ice chances
this afternoon into the overnight period, especially over
Michigan, where a quarter of an inch of ice is possible from
forming freezing rain. Impacts from freezing rain will increase
over western Pennsylvania and the northern Mid-Atlantic tomorrow.
This includes major urban areas like Washington D.C., Baltimore,
and Philadelphia. For areas farther north from New Jersey to
Massachusetts, 4-8 inches of snowfall is forecast on Friday with
more or less amounts locally. Road conditions will be treacherous
for those traveling back from the holiday. See the WPC key message
on the Post-Christmas Winter Storm.

Meanwhile, areas south of a stationary boundary located across the
Ohio Valley will be feeling rather warm for the upcoming weekend.
Friday-Sunday, high temperatures in the upper 70s to the low 80s
will be possible from Texas to the Carolinas and as far north as
the Tennessee Valley. Many cities could break or near record warm
high temperatures each day, some records going as far back as the
1880s. Low temperatures will also be warm in the upper 50s to low
60s. This December soupy airmass will bring chances for fog each
day along the Gulf Coast, some which may be locally dense and
bring low visibility.

Other weather in the country worth monitoring will be the Mountain
West as the West Coast trough and surface cold front move through
this weekend. High elevation snow and gusty winds are likely in
the higher elevations. Rain showers are likely in the valleys on
Saturday for the area. For the end of the forecast period on
Sunday, another shot of Arctic air will begin to funnel down into
the U.S. behind a cold front surging southward from Canada.

Merry Christmas !
