Day by day

Friday: Severe storms will be most concentrated in Nebraska, extending northeastward from a surface low expected to be near North Platte by evening. The NWS/NOAA Storm Prediction Center is warning that a couple of strong tornadoes are possible, and very large hail can be expected as well. Southward along a dry line into Kansas, storms will be more scattered, even isolated, but they could be very intense wherever they pop up.

Further south into Texas, a “cap” of very warm air one to two miles high will likely keep a lid on most severe weather until after dark, when a strong upper impulse moves across. Models agree that an arcing line of intense overnight storms with large hail and high winds will develop in southwest Texas, perhaps holding together long enough to reach the Dallas-Fort Worth and Austin areas by late morning.
