US Hazards for Friday, June 9, 2017US Hazards

Assess Your Weather Risk

Thunderstorms across the Northern Plains on Friday
Conditions will be favorable for the development of strong to severe thunderstorms across the region today. At the surface, low pressure over eastern Montana will allow for southerly flow over the area, bringing in moist air. This moist air combined with daytime heating will allow instability to build. An upper level trough moving into the Plains will provide lift for the development of strong to severe thunderstorms. Storms should begin to develop during the afternoon with large hail being the primary hazard, but isolated tornadoes cannot be ruled out. As the area of low pressure moves eastward, thunderstorms are expected to develop along the cold front today and tonight. Damaging winds will be the primary hazard, but some large hail cannot be ruled out.
