Severe Weather Threat Out on the High Plains This Afternoon...

Above is the latest severe weather outlook for today and tonight from the Storm Prediction Center (SPC) in Norman, OK. Severe storms are forecast within the yellow shaded areas on the image.

As expected yesterday, a cluster of strong to severe thunderstorms developed overnight in the Ohio Valley region, and moved Southeast.  The activity is currently moving into the Carolinas, and may continue to produce hail and/or wind gusts near severe limits as it advances toward the coast this afternoon.

Other thunderstorms may redevelop over portions of the Tennessee Valley region late this afternoon or early this evening, along and ahead of a cool front and along outflow boundaries left over from the overnight thunderstorm activity.  Large hail and damaging winds will be the primary threats from this activity, although an isolated tornado cannot be ruled out.

Further West, a trough of low pressure is developing out on the High Plains along the Colorado / Kansas border region, Southward into the Texas and Oklahoma panhandles.  Isolated to scattered thunderstorms are forecast to develop along the boundary late this afternoon and this evening.

Large hail, damaging wind gusts and a few tornadoes are possible with the activity that forms in this region.  Hail may exceed 2 inches in diameter within the red shaded and black hatched area on the image below:

If you live or have travel plans in the severe weather threat areas for today, please remain alert.  Listen to NOAA Weather Radio, a trusted local media or other source for later statements, watches and possible warnings.  Be sure to identify your best sheltering option ahead of time, that way you can move there quickly should threatening weather approach your area.
