Welcome! I’m an undergraduate Meteorology major at Plymouth State University and in this blog I’ll be talking all about the weather we experience here in Plymouth, New Hampshire. Today I’ll be discussing the nor’easter that we endured last Tuesday, March 13th. This was the third nor’easter to strike the northeast, and it brought blizzard conditions to much of New England, especially the coast. Here in Plymouth we were under a winter storm warning and meteorologists were predicting that we could’ve seen anywhere from ten to fifteen inches of powder. Well, while many New Hampshire counties did experience hefty snowfall amounts, the university did not. PSU took action and heeded the warnings by cancelling all classes for the 13th and calling a snow day. However, the road conditions outside and around campus seemed up to par throughout the entirety of the day. It turns out we only received about five inches of snow.
So, why did this happen? A Meteorology grad student explained to me that it had to do with the weather phenomenon called “down sloping.” A lot of snow fall forecasts don’t take the valleys into account. Because PSU is surrounded by so many mountains, the flakes are huge a couple thousand feet up, but evaporate by the time they reach us. So, we ended up having pretty small snowflakes throughout the entirety of the storm, which resulted in much lower snowfall amounts than predicted. But, it’s good that the university always stays on the safe side by heeding winter storm warnings. Aside from Winter Storm Skylar, it looks as though Plymouth could experience yet another nor’easter next week!
