An upcoming change in the weather pattern that AccuWeather meteorologists have been forecasting for the past several weeks is about to unfold. As the pattern change takes shape, a storm could provide opportunities for some rain in the coming days and weeks in portions of the parched Midwest and Northeast.
A large southward dip in the jet stream has been funneling cool air and smoke from Canada into the mid-Atlantic and Great Lakes regions this week. The same pattern has kept Gulf of Mexico and Atlantic moisture well away, with the exception of parts of New England where rain from the Atlantic has been a frequent visitor.
