The focus of the severe weather is expected to occur in the areas labeled “slight”, “enhanced” and particularly “moderate”, and it spans from east-central Texas north into southern Nebraska.

In particular, the area that has the greatest chance of experiencing damaging winds, hail, and tornadoes spans from south-central Oklahoma through central Kansas into southern Nebraska.

Cities in this region include Edmond, Lawton, Norman and Oklahoma City in Oklahoma; Wichita and Salina, Kansas; and Hastings, Nebraska. According to the Storm Prediction Center, this region (denoted by the purple hatched shading, left) has a 45 percent chance of experiencing significant severe weather (i.e. damaging winds, large hail and tornadoes) within 25 miles of a particular point.

However, strong to severe thunderstorms are not limited to Oklahoma, Kansas and Nebraska. In fact, a 30 percent chance of significant severe weather is possible for east-central Texas — including Wichita Falls, Denton, Dallas-Fort Worth, Arlington, and Plano. Further north, areas expecting an enhanced risk for severe weather includes Tulsa, Oklahoma; Kansas City, Kansas; and Lincoln, Nebraska.

The Storm Prediction Center’s outlooks are valid from 7 a.m. Tuesday through 7 a.m. Wednesday.

A few morning showers and storms are expected to develop throughout central Nebraska and northeastern Kansas, and a large cluster of thunderstorms are forecast to move through central Missouri.

Elsewhere, clear to party cloudy skies throughout the Great Plains Tuesday morning will allow the atmosphere near the ground to quickly warm and destabilize through the afternoon. Severe storms will likely fire up after 4 p.m. and continue through late Tuesday into the early morning hours on Wednesday.
