3-11-2018: Tuesday 3-13 Storm Update

Good evening!

Some info on the upcoming storm.

Timing
Snow starts during the overnight hours Monday night/early Tuesday morning. Heavy snow will take place from just before sunrise all the way before the mid-evening hours before gradually winding down by the late-evening. Residual snow showers will be possible all the way through Wednesday morning, though.

Hazards
Heavy snow and strong winds.

Uncertainty
Some guidance is indicating the potential for this to be a blockbuster snowstorm with higher amounts than currently forecast. This is a very notable possibility that must be monitored closely. On the flip side, a smaller amount of guidance is indicating a potential for snow amounts lower than is currently forecast. This also must be watched.

Impact
Heavy snowfall will create extremely dangerous travel conditions. Wind gusts around 40 mph are possible, which would lead to blizzard conditions if it verifies to that level with blowing and drifting of snow. Some minor wind damage is possible. However, property/tree damage and power outages will likely be only a very tiny fraction of what we saw with the last storm, because whereas the last storm featured an extremely wet snow, this storm will feature a drastically lighter snow that will be easier to move than even your average winter storm. With a much drier snowfall, power lines and tree limbs will not be weighed down, so wind damage would be the main concern. Some limbs that were weakened by the last storm could fall in some strong gusts, but other than that, I don’t see widespread damage and power outages being a thing with this storm.

Snowfall Forecast
I have Dracut now in 12-15″+. Note that these numbers could drastically change to levels that are higher or lower than they are now, so stay tuned for more info.

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!
