This weekend is going to end up very similar to last weekend, dry to start, then very wet to end.
High pressure keeps us dry into Saturday. We’ll start off chilly this evening under clear skies, but as winds shift into the southwest, temperatures will level off toward midnight, and could rise a bit overnight. Friday is about as good a day as we can expect for mid-December with sunshine and above normal temperatures. Clouds start to filter in Friday night and during the day on Saturday as low pressure begins to develop across the Southeast. As that low moves northward, we’ll have plenty of clouds on Sunday, with rain moving in by late afternoon or evening. The rain will likely be heavy Sunday night into Monday morning, with some gusty south winds bringing unseasonably mild air back in, with temperatures making a run at 60 in some spots. Monday is where the models start to diverge. Some of them bring the storm well to our west (central or western NY), some a little closer (western MA). Overall, this doesn’t make too much of a difference at this point, but the eastern track would likely mean the rain ends earlier, and the cold front swings through earlier, bringing an end to the mild air. Beyond that, the models rapidly diverge, which has significant impacts on the forecast around here for Tuesday and into midweek, but this forecast only goes through Monday, so we’ll worry about next week in our Weekly Outlook Sunday night.
