December 11 2017

We had some flurries overnight that you may have slept through, but it shows the atmosphere is ready. There next event will be more of a wintry mix, and then followed by truly arctic air Wednesday morning. The jet stream remains very active and the potential storms farther out in time show promise but nothing too organized to show for now.  Let’s take a look.

This be a quiet day with highs for us in the mid 40s.  We are watching this quick moving system just entering the Great Lakes and it will be the source of very frigid air that reaches us Wednesday morning. The question I posed last night was how it will track, and I suspect it may dive a little father south and east. That is why it may have a more of an impact on us that shown on the models.



The morning hours may bring a wintry mix which is still not being shown well on the models. If snow arrives, it will be light. The worst set up would be sleet or freezing rain. That is worth close attention.  The timing to pay attention to will be between 4 AM and 8 AM. This is the early drive time, but also when road temperatures will be coldest. Should the wait until later, then most of the commute will be over and the roads will be warmer. This is going to be one to watch hour by hour early that morning.


The evening will bring in some snow showers. Especially north of Baltimore. No accumulation expected.
