Storms that erupt from the lower Great Lakes Sunday to the Interstate 95 corridor of the northeastern United States on Monday can pack a punch for travelers and outdoor activities.
In most cases, the best bet for outdoor plans and projects will be the first part of the weekend.
A vigorous storm system that will trigger locally heavy, gusty thunderstorms over the Upper Midwest into Saturday night will spin across the Northeast by the first part of next week.
People should keep an eye out for changing weather conditions as they travel on the highway, attend ballgames or spend a day fishing on the lake. The downpours and gusty winds can occur with little notice.
"During Sunday afternoon and evening, thunderstorms from western and central New York to western and northern Pennsylvania, Ohio, Indiana, southeastern Michigan and southern Ontario will produce torrential downpours, localized damaging wind gusts and perhaps hail," according to AccuWeather Senior Meteorologist Brian Wimer.
A batch of drenching rain and thunder will develop over eastern New York state and push across New England to close out the weekend.
Meanwhile, areas from Portland, Maine, and Boston to New York City, Philadelphia, Baltimore and Washington, D.C., can expect most of the weekend to be dry. Some rain may fall late Sunday afternoon and evening.
"During Monday, areas from southeastern New York state to Virginia will be in the zone where torrential downpours can strike and the stronger storms could produce localized damaging wind gusts and perhaps hail," Wimer said.
Areas from the eastern Great Lakes to the Appalachians are likely to be hit by multiple showers and/or thunderstorms on Monday.
In a few extreme cases, thunderstorm winds can be strong enough to break tree limbs and cause sporadic power outages during Sunday and Monday.
Since many streams are running high in the area, there will be the risk of localized flash flooding. The rain can come down hard enough and fast enough to overwhelm storm drains and result in incidents of urban flooding.

Airline passengers should be prepared for delays, especially during the afternoon and early-evening hours, when the storms will be at their strongest level.
While the storm system will make steady progress across the Midwest, it is likely to stall in the Northeast during much of next week.
As a result, each day from Tuesday to Thursday will bring multiple rounds of showers and thunderstorms.
