Severe thunderstorms will erupt over central and southeastern Oklahoma and northeastern and central Texas later today.
The same storm bringing a raging snowstorm from Denver to Omaha is the culprit behind the dangerous thunderstorms.
Major cities, including Oklahoma City, Dallas and San Antonio, are at risk for damaging thunderstorms this afternoon and evening.
The threats of the storms include damaging wind gusts, hail, downpours and lightning. A few of the strongest storms could also spawn a tornado.
Motorists who travel along the I-20, I-35 and I-40 corridors should prepare for blinding downpours and potentially threatening storms.
Flash flooding can occur, especially in low-lying and poor drainage areas.
The thunderstorms will spread eastward overnight across Arkansas and Louisiana, putting Little Rock and Shreveport in the path of nasty weather. The northwestern suburbs of Houston could also get hammered.
On Saturday, coastal Texas to Mississippi, Alabama and Tennessee will be alert for thunderstorms, some of which may turn strong or severe.
Track the Threatening Storms:
Darby will continue to deliver locally heavy rain, gusty winds and rough surf to Hawaii into early Monday. But the tropical storm will provide long-term benefits.
Gusty thunderstorms will target the northeastern United States on Monday, but will fail to sweep away the baking heat wave gripping the region.
Dangerous heat will surge northward and send temperatures soaring across the northwestern United States during the final week of July.
Downpours will spread from the lower Mississippi Valley to eastern and central Texas early this week, delivering needed rain but raising the concern for flash flooding.
With the heat of summer comes many unwelcomed pests, including mosquitoes, ants, fruit flies, wasps and stink bugs, into outdoor spaces and homes.
