Severe Weather Possible in the Plains Tonight Through This Weekend
A round of severe thunderstorms will move through the Plains tonight with additional severe storms this weekend. A Severe Thunderstorm Watch is already in effect for the Texas Panhandle. The severe weather risk tonight extends from Iowa to the Mexican border.
The risk for tornadoes is low, with a minimal chance for large hail greater than 1″ in diameter. Strong wind gusts above 58 mph are possible with isolated severe cells.
The dry line will be the main focus for severe weather tonight. Warm and humid air has been building ahead of the dry line, pushed into the area by a southerly flow from the Gulf of Mexico. Much drier air will slowly surge eastward from the Four Corners, helping severe storms develop.
Thunderstorms will fire tonight from Nebraska to Texas and slowly move eastward. As instability decreases in the overnight, storms will likely diminish.
On Saturday, the severe weather potential shifts slightly to the east with a risk from the Western Great Lakes to the Rio Grande. Severe storms will likely develop in the afternoon ahead of a cold front advancing slowly to the east.
The front will likely weaken on Sunday and upper level support is expected to diminish. There is a marginal severe weather threat from the Ohio Valley into the Southern Plains.
