...Colder than normal across much of the nation with wintry weather
expected for some places...
The warm weather a couple of days ago is now just a memory as much colder
weather has settled in across much of the central and eastern U.S. An
upper level ridge of high pressure will build in over the West which will
allow a deep trough to remain in place over the central and eastern
states. Arctic air will continue to spill southward across the Plains and
eastward to the Mid-Atlantic coast, resulting in January-like
temperatures. Many locations will observe temperatures that are easily 10
to 25 degrees below seasonal averages, with perhaps a few record lows in
jeopardy. It's a different story for the southwestern U.S., where the
ridge building in will result in dry conditions with mild to warm
temperatures.
Now that the snow has departed the northeast U.S., attention now turns to
a developing surface low over the northern Gulf of Mexico along the
frontal boundary. Widespread rainfall is expected to develop across the
southern Plains and the Deep South, with the greatest amounts expected
across coastal areas of southeast Texas and southern Louisiana. Some
strong thunderstorms will also be possible across this region. Farther to
the north on the northern edge of the precipitation, a band of light snow
is likely from northern Arkansas to the southern Appalachians.
