A cold front is increasing the risk of strong to severe thunderstorms and heavy rain from the Midwest through the Great Lakes into the Northeast.
Storms are expected this afternoon and evening across Iowa, Wisconsin, and Michigan. On Tuesday, the storm system will expand east into Illinois, Indiana, Ohio, and upstate New York, impacting areas such as Chicago, Fort Wayne, Cleveland, and Buffalo. These storms may produce large hail, strong winds, and a few tornadoes.
Flash flooding is possible Tuesday from Chicago to New England, with rainfall totals of 2–3 inches and locally higher amounts. Be alert for standing water and reduced visibility.
In West Texas and western Oklahoma, isolated storms may develop Tuesday with a risk of small hail and damaging winds.
Fire weather conditions will be elevated across Wyoming, Colorado, and parts of the High Plains due to dry air and gusty winds between 15–25+ mph.
Out West, a system moving through the Pacific Northwest will bring snow to the northern Rockies and Sierra Nevada. Higher elevations above 8,000 feet could see 6–12 inches of snow.
By Tuesday, northern New England, especially Maine, may experience freezing rain. Even light ice accumulation can create hazardous travel conditions.
Drive safely and use caution in changing weather conditions, especially in areas with storms, heavy rain, or icy roads.
