Assess Your Weather Risk

Thunderstorm Potential for the High Plains into the Upper Midwest on Wednesday
Plentiful moisture overspreading the high terrain of the Central and Western US will provide an environment favorable for the development of thunderstorms during the day. This activity is expected ahead of a cold front extending from Minnesota into the Northern Plains and into the Rockies. While wind shear is weak, most activity is expected to remain below severe limits, a few storms may produce some strong winds or small hail. Activity should weaken as the sun sets, but a few storms may linger into the evening.

Potential for Thunderstorms across the Northern Plains on Friday
Enough moisture will be available to the north of a warm front to allow for the development of strong to severe thunderstorms across portions of the Northern Plains Friday afternoon and evening. Surface heating will increase instability while a strong jet stream provides the upper level support for the development of thunderstorms. Large hail and damaging winds will be the primary hazards with any storm that develops.
