Discussion
A strong cool front passed through the region in the overnight hours and has ushered in less humid and more comfortable air for the next few days. This air mass will be anchored by a strong high pressure system that originated in southern Canada and will work its way to the Northeast US. By the early part of the weekend, a much wetter overall weather pattern will set up for the eastern seaboard. An unusually deep upper-level trough is likely to form over the Upper Midwest and this will become a slow-mover. In addition, a strong coastal low pressure system may very well form in the Saturday night time frame potentially causing problems from the Jersey coastline to Long Island. As a result of this unfolding pattern change, the threat for showers and thunderstorms will increase later in the day on Saturday and likely continue through much, if not all, of next week.
