12/21 – Brittany’s “Arctic Air Ahead!” Wednesday Night Forecast
We’re on tap for a chilly and cloudy night with temperatures bottoming out in the low 50’s. This’ll be the warmest night we see for the rest of the work week because we’ll have a cold front make it’s way overhead tomorrow night which will cause temperatures to plummet.
Thursday night through Tuesday, this is the main time frame for impacts across our region. We have been advertising this Arctic airmass for what feels like almost a week now and it is almost here. With that we have already issued numerous Watches and Advisories this morning to signal the change from talking and checking your supplies and preparedness plans to finishing them up and about ready to enact. Impacts: 1 – Temperatures – Temps will drop 20-30 degrees in a matter of hours to below freezing by Friday morning. 2 – Winds – Courtesy of a tighter pressure gradient, winds are going to gust anywhere from 35-45 mph. This will affect holiday travel. 3 – Wind Chill – When we couple below freezing temperatures with strong winds, we get a brutal wind chill. Temperatures will feel like single digits.
