Soggy weather will spread across the Eastern U.S. on Sunday as two weather systems converge. A strong low pressure system moving over the Gulf states will continue pulling warm and moist air in from the Gulf of Mexico. Meanwhile, a cold front will stretch from the Northeast down the Ohio River valley into Mississippi River valley.
These systems in combination will produce widespread showers and thunderstorms from the Northeast through the Gulf states. Heaviest rainfall and strongest thunderstorms are anticipated over the Southeast, developing from the Gulf Coast through the Tennessee Valley.
There is a slight chance that these storms will turn severe with strong winds and large hail. Rainfall totals will range from 1 to 2 inches, with up to 3 inches possible in areas of severe thunderstorm development. Flooding will be a concern for much of the Southeast.
In the West, another area of low pressure is developing over New Mexico and western Texas. This system could produce some severe thunderstorms with strong winds and large hail.
A ridge of high pressure remains the dominant weather feature across the West Coast. This ridge will keep moisture away, allowing for another warm, sunny day. The Southwest deserts will remain under an excessive heat warning as high temperatures may reach into the lower 100s Sunday.
Temperatures in the lower 48 states ranged Saturday from a morning low of 19 degrees at Stanley, Idaho, to a high of 94 degrees at Edinburg, Texas.
