STORMS FROM THE GREAT LAKES TO THE MID-ATLANTIC

Severe Weather Discussion

Severe weather will be relatively limited today, with the primary threat focused across the northern Plains and northern Rockies. Thunderstorms developing from South Dakota into portions of Montana and Wyoming will be capable of producing large hail, damaging wind gusts, frequent lightning, and an isolated tornado during the afternoon and evening hours.

Outside of this area, many thunderstorms will remain below severe limits, although locally gusty winds and brief heavy downpours will accompany the stronger cells.

Looking ahead, a stronger storm system dropping southeast from the Pacific Northwest will increase the severe weather threat across the Great Lakes on Sunday and Monday. As the associated cold front moves eastward, thunderstorms are expected to organize into lines and clusters capable of producing widespread damaging winds, large hail, and locally heavy rainfall. A few tornadoes will also be possible with the strongest storms.

By Tuesday, the severe weather threat is expected to shift into the Mid-Atlantic states as the front continues east. Thunderstorms in this region may produce damaging wind gusts, hail, torrential rainfall, and an isolated tornado before the front pushes offshore.

Overall, today's severe weather will be concentrated across the northern Plains and northern Rockies, while a more widespread threat develops across the Great Lakes early next week before advancing into the Mid-Atlantic.
