 The frontal
boundary will extend from the Great Lakes through the
central Plains and down into the Southwest throughout the day, while the associated trough drops southward into the
central and southern Rockies. Strong winds from the trough will usher a colder air mass into the West, allowing temperatures to drop significantly and support snow development in the Four Corners,
central Plains and the upper Great Lakes. Expect winter weather advisories and winter
storm warnings to remain in effect over areas of the Four Corners as snow accumulations reach up to 8 inches in the higher elevation. The southern end of this system will draw moisture from the Pacific across the Southwest, triggering rain and high-elevation snowfall. On the leading edge of this system, scattered rain and snow showers will be possible from areas of
the central Plains through the upper Great Lakes.Elsewhere, high pressure will dominate the East with calmer weather conditions. Mostly clear skies and early morning temperatures near the freezing mark may support frost development in portions of northern Florida and parts of southern Alabama and Georgia.
Temperatures in the Lower 48 states Wednesday ranged from a morning low of 6 degrees at Land O' Lakes, Wis., to a high of 78 degrees at Daggett-Barstow, Calif.
