A significant weather system is affecting the United States this weekend, bringing severe weather threats across multiple regions. A tornado watch has been issued until 10 a.m. Saturday for much of central Alabama, including counties such as Autauga, Bibb, Calhoun, Cherokee, Chilton, and others. The National Weather Service warns of a line of thunderstorms capable of gusty winds and brief tornadoes, with localized flooding also a concern. Meanwhile, a broader storm system is impacting the eastern two-thirds of the country, with forecasts predicting thunderstorms, snow, and strong winds from Wednesday through Sunday. Starting Wednesday night, thunderstorms may occur in the Southern Plains, with snow in the Rockies and Mountain West. The system will intensify on Thursday, spreading rain as far north as the Great Lakes and bringing thunderstorms from eastern Texas into the Mississippi Valley. By Friday, snow could extend into the Plains and Rockies, while thunderstorms increase in the South, reaching as far north as upstate New York and New England. Saturday's forecast indicates snow in parts of the Great Lakes and heavy rain in the East, with strong winds across the Midwest and South. Wind gusts over 40 mph are expected, potentially causing downed trees and power outages, especially in areas experiencing snowfall, which could also reduce visibility. The cold air associated with the storm will briefly impact the Midwest, South, and East but is not expected to be extremely cold. The severe weather threat remains relatively low for tornadoes, with the main concern being gusty winds and possible brief tornadoes, particularly in Alabama and the Deep South. Heavy rain may cause flash flooding, especially in the Tennessee Valley. The forecast emphasizes caution due to the potential for damaging winds and localized flooding. Overall, the weekend will feature a mix of weather conditions, including snow, rain, wind, and the risk of severe thunderstorms, with impacts varying by region. Authorities advise staying updated on weather alerts and taking precautions against adverse weather conditions.
