If you’ve been wondering why you’re so thirsty the past few days or been suffering numerous static shocks, wonder no more. The air is very dry across southern New England. As of 3 PM, the dewpoint at BDL is -10. With a temperature of 22 degrees, this gives them relative humidity of 23%. Now, take that same air, bring it indoors, and heat it up to 70 degrees. Now the relative humidity in your home/business is 3.7%!
An upper-level short wave approaches the area tonight (circled in purple on upper-left panel above). Low pressure will also start developing well offshore (also circled). Occasional, light snow/snow showers will develop after about 7 PM this evening. Only looking for a coating to an inch or so, with lows 9-15. The light snow ends before most of us wake up Saturday. Otherwise, mixed sun & clouds tomorrow. A northwest breeze at 10-15 mph and highs in the 20′s. Saturday night will be partly cloudy to clear, with lows between 7-14. Sunday looks sunny (and still a bit breezy for a while) with highs between 26-31. We should be able to reach or exceed freezing in many parts of the area Monday, however it looks like a little light snow will develop, then change to a light mix later in the day as a warm front nears.
