3/21/2018 – Morning Update #1

Good morning!
 
No changes have been made to the forecast from last night on the map.
 
Timing
Snow starts mid afternoon today, with snow peaking during the late evening and early overnight hours, before gradually winding down during the rest of the overnight hours. Snow is done by – or during the early portion of – the morning commute tomorrow.
 
Uncertainty
The exact storm path, as well as whether an upper level layer of dry air erodes, will dictate how much snow we get, and there will be a fairly sharp northern cutoff. There is unusually high uncertainty with this storm for a day forecast
 
Totals
Same deal as last night. Dracut is in a 3-6″+ zone. We aren’t too far south of the 0-3″ zone, and not too far north of the 6-10″ zone, so what happens is dependent mostly on what happens with the upper level dry air and the precise storm path. Either of those zones could shift and make their way here.

Beyond
Tomorrow approaches 40, Friday and Saturday break into the low 40s, before Sunday marks a return to chilly conditions in the 30s.

Have a great day!

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!
