US Hazards for Friday, July 22, 2016

US Hazards

 

Region 1

A surface low will develop in Montana and move east-northeastward with a warm front extending into North Dakota late this afternoon. Warm, moist, and unstable air will overspread the region as the warm front moves northward during the day. Thunderstorms are expected to develop during the late afternoon over western portions of Region 1. Some of these storms could become supercells capable of large hail, damaging winds, and tornadoes with the greatest tornado risk across western North Dakota. Storms should become linear as the evening progresses and push eastward during the late evening and overnight hours. The primary threat will then become damaging winds. 

 

Update 12:59pm: Severe Thunderstorm on the North Dakota/South Dakota border producing large hail and damaging winds.
