Thursday Morning Weather Discussion

Good morning. Let's take an updated look at the storm system that will effect parts of the Northeast this weekend. Model guidance has been fairly consistent with this and I am confident this is an idea of what to expect..

Significant accumulations of 12+ are possible in the dark blue zone especially  closer to the Boston Area. In the outer edge of blue zone it would be less than 12+. The light blue zone is the chance at a few inches. 

There still can be some changes but the models should really have this locked up by tomorrow. I do not expect significant snow to extend into NJ or eastern PA. 

Bitterly cold air still arrives this weekend as well. Check out projected lows on Monday morning..

Yes its due to the polar vortex over our area. Also that big ridge over Alaska is key. 

Still watching for a storm middle of next week..

Based on the pattern which includes a lack of blocking this can end up being an interior heavy snow threat and rain along the coast. We will have to wait and see how this pans out.

The north Atlantic oscillation (NAO) has not behaved this year at all and has stayed in its positive phase most of the winter. This is a reason balt/wash and phili and even parts of NJ have missed out on big storms. I see no evidence that will change over the next 10 days.

Thanks for clicking in.
