Areas of light to moderate snow will translate east from eastern Oklahoma, southern Missouri and Arkansas this morning into and across the Tennessee Valley, eventually reaching the Mid-Atlantic region tonight.
Snowfall accumulations of 4 to 8 inches are expected from near Memphis into the central Appalachians.
Sleet and freezing rain will affect locations just south of the snowfall, with ice accumulations locally in excess of 0.25 inches from far northeastern Alabama into northern Georgia and upstate South Carolina.
Light snowfall accumulations (1 to 3 inches) are anticipated farther north from the Ohio Valley into northern portions of the Mid-Atlantic region.
Below average temperatures from the south-central to southeastern U.S. will moderate into the weekend but remain roughly 5 to 15 degrees below average on Saturday into Sunday.
Across the western U.S., strong high pressure over the Great Basin will begin to weaken during the day today, but Critical fire weather conditions will continue over coastal locations of Southern California through the remainder of this morning with localized gusts to near 60 mph.
While wind gusts are likely to weaken into this afternoon and evening, remnant gusty winds and low relative humidities will continue dangerous conditions into the afternoon and evening.
Elsewhere across the western U.S., a quick moving cold front will sweep across the Northwest and Great Basin today, bringing coastal rain to the Pacific Northwest and mountain snow to the Cascades, northern Great Basin into the northern and central Rockies. ■
