Today will be another very warm and humid summery day for the Northeast with more widely scattered showers and thunderstorms popping up this afternoon and evening. Due to the stronger mid-level ridging, very weak wind fields and less instability with warmer mid-level temperatures, these storms will likely be less intense and fewer and father in between than on Wednesday. But will still be very slow-moving and capable of producing some heavy rainfall and flash flooding in some spots.
However, a shortwave energy embedded in a larger upper-level trough will be amplifying over the Great Lakes Friday and Saturday. This will cause low pressure to deepen and track northeast through the Great Lakes into Southeast Canada on Friday and Saturday. As it does so, it will drag a frontal boundary will be moving be slowly through the region, as ridging from the Western Atlantic gradually breaks down. Large scale ascent and lowering heights will support more numerous showers and thunderstorms over the Interior Northeast again.
