Region 1
An upper level trough will aid in the development of a surface low over the High Plains on Thursday. This low, as well as a cold front and dryline extending southward and a warm front extending into the Upper Mississippi Valley, will provide a focus for thunderstorm development beginning during the early evening hours. There is some uncertainty in regard to overall coverage. However, any storms that develop will have the potential for large hail and damaging winds. Isolated tornadoes cannot be ruled out early in the event from western and central Nebraska southward into the overnight hours. Activity should weaken during the overnight and early morning hours.

Region 1 Thursday, March 23, 2017Region 1

Region 2
A slow moving cold front pushing southward through the Florida Panhandle will provide a focus for thunderstorm development across the region. Thunderstorm activity is currently limited to the eastern coast and offshore, but will gradually increase into the afternoon and evening before dissipating. Due to increased instability along and south of the front, there will be a potential for a few strong to severe thunderstorms. Gusty winds and hail will be the primary hazards with any thunderstorms that develop.

Strong To Severe Thunderstorms Possible Saturday from Central Gulf Coast to Tennessee Valley
The area of low pressure responsible for the threat of severe thunderstorms across the Plains Thursday and Friday will weaken as it moves across Missouri on Saturday.

Storms are likely to weaken by mid afternoon, but damaging winds are likely in association with the squall line before significant weakening occurs.
