Strong to Severe Thunderstorms Possible Thursday for the Missouri Valley
An upper level disturbance in the Intermountain West will track into the Plains on Thursday. The associated surface low will track into the Tennessee Valley throughout the day. During the early afternoon and early evening, southerly winds will bring moisture into Missouri and eastern Oklahoma. This warm moist air combined with instability and moderate to strong wind shear will result in the formation of scattered showers and thunderstorms ahead of the cold front during the afternoon and evening. Some of these storms will become strong to severe with the potential for large hail, damaging winds, and tornadoes.

A Look Ahead
An area of low pressure will continue to track southeastward along a stationary boundary set up across the Central Plains. Some moderate to heavy snowfall may develop from the Central Plains southeastward into the Tennessee Valley. Model guidance has gotten into better agreement that several inches of snowfall will be possible, especially across the Midwest and the higher elevations of Tennessee and the Appalachians where colder air will be in place.
