Arctic Blast Then Wintry Start To The Weekend

Arctic Blast Then Wintry Start To The Weekend

Tuesday December 13 – The infamous Polar Vortex will be skirting northern New England, sending the first true blast of arctic air our way Thursday and Friday. Highs both days like to stay in the 20s for most of us. Then another storm system will arrive on a western track. That means a warm up for us, but it should start off with snow and ice first. Saturday morning will bring snow (from midnight to around dawn) changing to freezing rain, then thawing to rain during the day. The back side of the storm could have the cold air catch up and change it back to wet snow or a mix during the Ravens game in Baltimore. T

he purpose of this post is to compare two main models for contrast of the storm tracks.  Not specifics yet, as I just want to watch how the models are trending. I don’t want to show the snow potential maps this early, but the twist here is that the GFS Model is the more aggressive one this time. It has a colder track and is producing potential snow about double that of the Canadian for central Maryland and southern PA. I will start to show the snow maps tomorrow and get into more details then. Here are the two sliders showing the timeline this weekend.
