Good morning everyone, This e-mail is to raise awareness of scattered snow squalls for this afternoon into early tonight, with much colder air tonight contributing to the development of patchy black ice on untreated surfaces tonight. Details on each below: *Scattered Snow Squalls* *Where: *Possible anywhere in Southern New England, though greatest potential is into interior MA (near and west of I-495), northern RI and northern CT. *When:* Between noon and 6 PM today. *Impacts:* While not everyone will see snow squalls, areas that do will see short-lived heavy snow capable of brief whiteout conditions and gusty winds. A quick coating-inch of snow accumulation is possible in less than an hour's time in snow squalls. These conditions may make for difficult travel which could impact this afternoon's commute. *Uncertainty:* Coverage of snow squalls will be localized, with several areas staying dry. There is less certainty on snow squalls advancing into the coastal plain with temperatures hovering near or just above freezing. Following attachment is a Special Weather Statement sent this morning about our expectations for snow squalls this afternoon into tonight. *Black Ice/Freeze-Up* *Where: *Possible anywhere in Southern New England where snow and/or wet pavement exists. *When:* Developing tonight into the overnight. Threat should end after sunrise Thursday. *Impacts:* Wet or slushy pavement will turn slippery if untreated. Shaded locations, side streets, bridges and overpasses are most vulnerable. *Uncertainty*: Generally low with high confidence on sub-freezing temperatures. Gusty winds and drier air tonight may evaporate damp pavement in spots before freezing. Attached is a look at tonight's low temperatures based on our overnight/early morning forecast. While we are still fine-tuning these low temperatures, any change will likely be minimal. Please let us know if you have any questions or concerns! Thank You!
