A sign that the end of summer is upon the horizon, is always that first night where overnight lows dip into the 40s across the Hudson Valley. That seems possible, if not likely, tonight around the region. After looking at multiple sources of data, with a NE flow, low dew points, clear skies, and calm winds expected overnight… several parts of the area could dip into the upper 40s, and possibly even some mid 40s across the northern half of the valley.
The record low Monday morning in Poughkeepsie is 43°, set in 1963. The overnight low there should bottom out around 49° or 50°… but some aggressive data like the image shown from the GFS model, suggests mid 40s can’t be ruled out. Any way you slice it, a crisp… cool, fall preview is in store overnight.
Monday looks quite nice… after a chilly start. Expect mostly sunny skies, and afternoon highs in the mid 70s. As our cool, dry air mass continues to hold over the Hudson Valley to start the work week.
