Very high dew points are found east of the Mississippi right now with lower dew points way out west. This is the drier air that lies behind a cold front which is moving east but very slowly. Tomorrow the front will still to our west so we can look forward to another humid day. Morning fog will give way to hazy sunshine and I expect scattered showers or thunderstorms to break out in the afternoon. The activity will continue into the night as the front moves through our region.
A southerly wind promises to lead to a wide range in temperatures Tuesday with much warmer readings (mid 80s) toward New Hampshire and much cooler temperatures (mid 70s) along the Maine coast. The front will be east of us by Wednesday morning with drier air moving in during the day. There could be some showers around early but they will give way to sunshine as the drier air arrives. Temperatures should have no problem reaching the lower to mid 80s.
Thursday looks to be the pick of the week with mostly sunny skies and comfortable humidity levels. The heat and humidity will return on Friday but won't be here very long. A cold front is expected to move through our region Saturday with cooler and drier air in its wake for Sunday.
