Region – I just want to be sure that you are up to date on the possibility of some very heavy snow squalls coming in late this afternoon with the arctic front. A brief period of very heavy, blinding snow is possible in some areas (think heavy rain in a summer thunderstorm falling as snow) dropping visibility to near zero, accompanied by strong to damaging wind gusts of up to 60 mph. We may even be treated to thundersnow in a few isolated areas! These squalls mark the leading edge of bitterly cold arctic air moving into our area. Wind chill values could drop as low as -30° overnight, and actual temperature could fall to as low as -10° in the coldest spots, but most will see low temperatures around or just below zero. Daytime high temperatures Thursday will be between +5° to +15° in the “warmer” coastal locations. Fortunately, this will be a short outbreak, as temperatures will rebound into the 20s on Friday.
