Good evening!
Precip Type
Rain to snow.
Timing
Rain showers are in the area as we speak; they will change to snow overnight, continuing and then leaving early to mid morning.
Uncertainty
Uncertainty is wicked high. This is a Norlun trough, notoriously difficult to predict in nature, and thus snowfall amounts could range for parts of the area (namely northeast MA) anywhere from a significant snowfall to a very minor snowfall.
Potential Impacts
If the Norlun even meets half of its local potential, there would be some impacts: the morning commute would be slick, especially as rain that has already fallen in spots will freeze up during the night after a change to snow. To allow time for clearing of both home driveways and school facilities, schools could potentially have delayed openings. Impacts get more significant with more snow and less meaningful with less snow.
Amounts
These could change drastically, so be on your toes tonight/tomorrow morning.

Hello! I'm Nathan Coram, a 19 year old meteorology student and weather geek, and am going into my junior year at UMass Lowell as a meteorology major. I am the current Vice President of the UML American Meteorological Society Local Student Chapter. Prior to at UML, I attended the Dracut school system for my K-12 years, having graduated from Dracut High in 2018. I first got into weather with the December 2008 ice storm, which knocked out my electricity for 4 days. I had no idea how it could be raining and becoming ice immediately, and how rain can knock out power. (Now I do - warm layer aloft, cold air at surface). But I didn't really get into it until the heat of July 2010 and specifically a few severe weather events during that month, followed by the year 2011, which featured several high profile weather events. Since then I have had a growing interest, and am hoping to make it into the meteorology field, preferably with NOAA/NWS. But for now, I'm blogging here, helping with the UML Weather Center social media, and tweeting about the weather on my own account as well. Thanks for visiting!
