Cool and warm air will battle across the Northeast this weekend as more Canadian wildfire smoke degrades air quality. Adding to the complex weather pattern, severe thunderstorms could bring damaging wind gusts, flash flooding and a few tornadoes.

Cooler, less humid air pushed southward from eastern Canada into New England, New York and parts of Pennsylvania and New Jersey on Thursday behind a cold front. The front also ushered in thick wildfire smoke, resulting in "dangerous" air quality from Chicago to Washington, D.C.
Very warm, humid air will meet this air and cause it to pause its advance over parts of the Appalachians and the mid-Atlantic on Saturday. Highs will generally be in the 80s F, with parts of Maryland, Delaware and Virginia climbing into the 90s. Some areas from New England to New York City and the Poconos will remain in the 70s.
