Next snow chance just around the corner

* Slow melting better than no melting: Full Forecast *

Next Chance of Accumulating Snow: Monday-Monday Night
Probability of Accumulating Snow (1" or more): 70%

It seems Mother Nature may be intent on making life difficult for school administrators. Some school systems have decided to hold classes on President's Day to make up for lost time, yet the chance of accumulating snow sometime Monday and/or Monday night hasn't gone away, though the exact timing is uncertain and overall forecast confidence is low.

Low pressure riding the polar jet stream will likely pass just to our south on Monday and could transition into yet another coastal storm. Whether we're looking at a sizeable storm, or little to no snow, depends on how far south or north the potential coastal system develops (the farther south, the better chance for more snow), and whether or not the precipitation "skips over" the D.C. area during the transition.

While not as intense, the overall look and track of the upper-level energy associated with the incoming area of low pressure isn't all that different from that of the last storm, and may be enough to squeeze out some significant snow despite the apparent lack of moisture with this system compared to recent ones. So, we do need to watch how things play out over the next couple days.

Here are our latest accumulation probabilities, which are likely to change as we get closer to this potenital storm:

30%: Less than 1"
30%: 1-3"
25%: 3-6"
15%: 6"+

The Snow Lover's Crystal Ball appears when the potential exists for accumulating snow beyond 24 to 36 hours.
