Its been an active week of severe weather and the chance for severe storms continues into the weekend. Already today, severe thunderstorms produced wind damage in Oklahoma. Wind gusts were clocked above 70 mph, knocking down trees, power lines, and creating some structure damage.
The severe weather risk continues this afternoon and evening in the Southern Plains with an enhanced risk posted from the Storm Prediction Center. It includes areas from Dallas into the Arklatex.
All modes of severe weather are possible tonight: isolated tornadoes, hail larger than an inch in diameter, and wind gusts greater than 58 mph. The focus area is around the Red River of the South.
Heavy rain is a concern as well. Nearly 3″ of rain fell near Tulsa, producing areas of flooding on roadways and standing water in ditches. Several Flash Flood Alerts continue throughout the region. Another 1″ to 3″ is possible in the heaviest thunderstorms tonight that could produce additional flooding.
The system will continue to move slowly eastward. This will be the focal point for severe storms tonight, especially in areas ahead of the low and along the associated fronts.
The severe weather outlook for Saturday begins to shift eastward into the Tennessee and Mississippi Valleys. As the low pressure center and fronts slide into the Deep South, more severe storms are likely to fire in Mississippi, Alabama, and Tennessee.

On Sunday, upper level support will start to shift to the north, away from the surface features. This will help to reduce severe weather chances. A marginal risk continues across the Southeast.
