South

The Southwestern upper-level low will finally be coaxed eastward over the weekend. Heavy inch-plus rains over Texas on Saturday will shift into the lower Mississippi Valley, Tennessee Valley, Florida and finally Georgia and the Carolinas on Sunday. Colder air will hold on the east side of the Appalachians. A very wet low-pressure system will develop along the Texas Gulf Coast later Saturday and head first for northern Alabama and eastern Tennessee Sunday and then for the Mid-Atlantic Monday. Sunday night into Monday morning, the heavy rain will move from the Deep South through the Carolinas. While most of the South gets to dry out Monday, rain and snow showers will linger in the Tennessee Valley and the southern Appalachians. Colder air will pour into the Southeast Monday and Tuesday in the wake of the storm. A weaker system will bring light rain to Texas Wednesday and the Southeast Thursday.

 

Northeast

An upper-level disturbance and cold front moving through the Great Lakes will bring some snow to parts of Upstate New York and both northern and western Pennsylvania tonight and Saturday. Temperatures across the Northeast this weekend will be 5 to 15 degrees below average. The weekend is the calm before the storm. A Midwest storm and a Southeast storm will attempt to converge on the Northeast on Monday. To start the workweek, snow and sleet will quickly change to chilly heavy rain over the eastern Mid-Atlantic, southeast New York and coastal southern New England. A heavy mix of snow, sleet and freezing rain will hit western Virginia, south-central Pennsylvania, the Poconos, the Hudson Valley and the remainder of southern New England. Heavy snow will hit West Virginia, western Pennsylvania and the remainder of Upstate New York. The deepening windy low-pressure system will move from the Mid-Atlantic to southern Quebec Tuesday with heavy snow for western New York, a wintry mix across northern New England and lingering snow showers for the mountains of Pennsylvania and West Virginia. Cold air and continued interior snow will linger through Thursday.

 

Midwest

A few snow showers will linger around the Great Lakes on Saturday, but on the whole the Plains and Midwest will be very quiet the first half of the weekend. Temperatures will be 5 to 16 degrees above average in the Plains (50s to near 60 Nebraska and Kansas) and up to 10 degrees below average in Michigan and Ohio (teens, 20s and 30s). Then a big change arrives. On Sunday, a new low-pressure area and cold front will sweep into the region with snow for northern Michigan and much of Wisconsin plus showers for the lower Missouri Valley. On Monday, this storm will begin to team up with a storm from out of the South. Winds will be on the increase. Snow could be heavy in eastern Lower Michigan and eastern Ohio. Lighter snow will fall across much of the remainder of the region minus the central Plains. Lake snows will linger Tuesday and Wednesday with below average temperatures from the Mississippi valley eastward.

 

West

The Pacific Northwest will see a return to showers and mountain snow in the coming week although the amounts will probably be on the light side. Meanwhile, the Northwest dry weather will continue through the weekend. A new storm will come into southwest Oregon and the northern half of California on Sunday. The heaviest rain will fall over northern California. On Monday, showers and mountain snow showers will push northward into Washington and eastward toward the northern and central Rockies. The Southwest should be largely spared except maybe for a few sprinkles in Southern California. Meanwhile, the current Southwest upper low will finally shift eastward and out of the region by Sunday. A few showers, mountain snow showers and thunderstorms will linger over the Four Corners' states on Saturday and over Colorado and New Mexico on Sunday. Temperatures will tend toward above average readings in the Northwest and slightly below average readings in the Southwest right through midweek.
