...After a cold start across the Deep South, warmer weather will spread
eastward from the Plains as the weekend approaches...

...Cooler and unsettled weather for the western U.S. through Saturday

After Thursday morning lows in the teens for many locations extending from
eastern Texas to the central Gulf Coast, warmer weather is on the way.
High pressure currently situated over the lower Mississippi River valley
will slowly shift east over the next two days, allowing a southwesterly
wind to bring in warmer air from the Plains and Gulf of Mexico. Highs
across the Deep South will still be 10 to 20 degrees below average today,
but are expected to be near to above average for Saturday. For Saturday,
high temperatures in Oklahoma, Texas and Louisiana should warm up into the
60s and 70s, a significant change from the snow and ice experienced
earlier in the week.

After the departure of a winter storm from the Mid-Atlantic coast this
morning, most locations east of the Rockies will be dry through Saturday
morning, except for light snow in the vicinity of the Great Lakes and some
showers over the eastern half of Texas into Louisiana on Friday and

Out west, a change in the upper pattern will allow for the infiltration of
colder, Pacific air along with rain and higher elevation snow developing
through the rest of the week. Rain associated with a cold front will
continue to move inland today, but as colder air flows in behind the cold
front, a rain/snow mix is expected to develop across some of the higher
elevations of California, Oregon and Idaho. By Saturday morning, many
inland locations will be snowing with rain limited to inland valleys and
coastal locations along the West Coast. Some more significant snowfall
accumulations are possible for portions of Nevada into Utah beginning
Friday and lasting into Saturday, with Winter Storm Watches already in
place over parts of northeastern Nevada. Needless to say, temperatures
will be falling below average west of the Rockies by Saturday.
