The weather pattern will do a flip-flop this weekend with the Central and Western U.S. topping the headlines while the East gets a much needed break.
WeatherBug Meteorologist Addison Green has the latest in his exclusive WeatherBug National Outlook.
The first major winter storm of the season for the Plains and Rockies will bring heavy snow and high winds. Three to 5 inches will blanket western Colorado while a general 1 to 4 inches will fall across the central and northern Rockies into the Dakotas. The snow will be coupled with northeast winds that will gust up to 30 mph, creating more blizzard conditions along and north of Interstate 94.
The warm side of the same low pressure will bring severe thunderstorms to the Central Plains. While most of the day will be dry and quiet, a cold front will sweep into the Plains in the early evening following sunset. Storms with large hail and gusty winds will quickly develop from southern Minnesota into northwestern Oklahoma. Places like Lincoln, Neb., Topeka and Dodge City, Kan., and Gage, Okla., are most at risk for late-day menacing storms.
High pressure will govern the weather from the Mississippi Valley to the East Coast. Warm southwest winds will nudge temperatures 15 degrees above normal through the Mid-Mississippi Valley with widespread 70s. The Deep South and Gulf Coast will also enjoy these pleasant readings with 60s in the Mid-Atlantic and much cooler 30s, 40s and 50s for the Great Lakes to Northeast.
The West will be the coldest spot with 20s, 30s and 40s from Montana to northern Arizona and into the Northwest. Even places like San Diego and Los Angeles will be 10 degrees below average in the 60s.
A strong cold front will slice through the Mississippi Valley bringing rain, gusty thunderstorms and falling temperatures. A fresh storm will bring rain to the Northwest Coast while the East remains locked in a tranquil weather pattern.
Lines of showers with embedded thunderstorms will swoop across the Plains into the western Great Lakes and Mid-Mississippi Valley ahead of a potent cold front. The strongest storms will form during the prime afternoon heating in the Mid-South. Gusty, damaging winds will be the main threat in places like Little Rock, Ark., Shreveport, La., and Tyler, Texas, although a few tornadoes aren`t out of the question.
A few more snow showers will plaster the Central Rockies while a fresh storm delivers late-day rain to the Northwest Coast.
Otherwise, the western cold weather will sweep into the Plains in the wake of the cold front while the East continues to warm up under increasing southwest winds. Places in the Plains that will be in the 70s today will need to break out the jackets with cooler 30s and 40s for Sunday. These chilly readings will be widespread across the Mountain West to conclude the weekend.
The Deep South to Northeast will enjoy 60s with a few 70s sneaking in along the Interstate 95 corridor south of Washington, D.C. The Southwest will also see highs in the 60s with balmy 80s along the Rio Grande Valley.
