Clipper Tonight, Bigger Storm End Of The Week

This week may well be remembered as one of the coldest over the past two years. This week will also be marked by bookend snow potential. A mild weekend has led way to crashing temperatures, snow chances and the lake effect snow machine cranking.

For our area, we are looking at a clipper moving through this evening. This will reinforce cold air, and bring us a chance at a period of snowy weather. This is not by any means, going to be a big event. In fact, this is going to resemble more along the lines of tracking a line of storms in the summer time. For those that see the squall move in, a quick burst of snow will cover the ground and could impair driving. A general coating to 1" can be expected.  Expect this to last less than an hour. The hi res NAM simulated radar has this over the area around 8pm tonight:


The real event for this storm tonight will be for areas in eastern New England (Boston to Portland, ME). They are going to experience what is known as a Norlun trough which will enhance the snowfall and really up totals in that area where 6" plus can be expected. I posted this a couple years ago when we had a Norlun trough move through our area, but here is the refresher for those interested:

After this clipper moves through, our attention will turn towards Friday. Another storm is poised to move in and bring us a chance at some measurable snow fall. Weather models have been all over the place with this one, but the vast majority do show a storm. The next couple of days will be spent monitoring the weather models and trying to narrow down a consensus. We are looking at a Miller B storm, and historically, these are one of the most tricky storms to forecast. They can also lead to some of the most intense storms (a la our thunder snow storms for two winters ago.) For now, know that a chance exists and we will see how this plays out this week. Bundle up, going to be a cold one and hopefully snowy!
