Continued Thunderstorms for New England on Friday
Showers and thunderstorms will continue across New England through midday ahead of a cold front. Damaging winds and an isolated tornado will be the primary hazards with these storms. The threat will end as the cold front moves offshore this afternoon.

Thunderstorm Risk for Friday

Thunderstorms Friday across Montana
As moisture moves northward across the region, instability will build through the afternoon, allowing for the development of scattered thunderstorms as a cold front moves eastward. Damaging winds and large hail will be the primary hazards with these storms. 

Major Cities in Region: Great Falls, MT, Glasgow, MT

Thunderstorm Risk for Friday

Potential for Thunderstorms for North Dakota and Minnesota on Saturday
Thunderstorms may develop across portions of North Dakota and Minnesota Saturday afternoon and evening as instability increases. With strong instability and wind shear in place, thunderstorms will likely develop. Damaging winds and hail will be the primary hazards with these storms, but isolated tornadoes cannot be ruled out.

SPC Convective Outlook for Saturday

Risk for Thunderstorms Sunday from the Eastern Dakotas into the Upper Great Lakes
Thunderstorms may develop from the Eastern Dakotas into the Upper Great Lakes on Sunday. There is some uncertainty due to thunderstorms expected to move through the region Saturday night and Sunday morning. If this activity moves out of the area early enough, strong to severe thunderstorms may develop along a cold front Sunday afternoon and evening. Damaging winds and hail will be the primary hazards with any storms that do develop.

SPC Convective Outlook for Sunday

Tropical Update
Hurricane Beryl (green oval) is currently 1140 miles east-southeast of the Lesser Antilles and moving westward at 14 mph. Sustained winds are at 75 mph. Some strengthening is expected over the next 24-36 hours. Beryl is expected to increase in forwarding speed through the weekend and weaken to a tropical storm early Sunday.

Showers and thunderstorms are increasing in association with an area of low pressure a few hundred miles southeast of the North Carolina coast (red oval). Environmental conditions are expected to be conducive for additional development, and a tropical depression is likely to develop over the next couple of days while the system moves northwestward. It will likely stall near the coast of North Carolina over the weekend.

A Look Ahead
The area of low pressure off the coast of North Carolina will move closer to the coast on Monday and move northward along the East Coast through the week. Current model guidance indicates that the heaviest rain may remain offshore. Light showers may develop across the Ohio Valley and Southeast on Monday and Tuesday as a result of daytime heating. On Wednesday, thunderstorms will extend from the Northeast into the Appalachians ahead of a cold front. Thunderstorms may develop across the Northern Plains and Upper Midwest as a cold front moves through the region on Thursday.
