[8 PM, 1/23/17] Storm Update

Good evening!

Here is the latest on the storm. Apologies for the brevity, I have been studying for physics and math midterm exams taking place tomorrow.

Precipitation Types and Timing

Mix of snow, sleet, rain, and freezing rain; most of the snow and sleet stuff falls as sleet. Freezing rain is going to stay well inland; while other areas go from snow/sleet to a period of heavy rain. The heaviest precipitation is overnight tonight into tomorrow’s morning commute, tapering late morning; there will be rain at times throughout Tuesday into Tuesday night.


Snow and sleet: I have gone up a bit here. Most of this is sleet.slide4

Freezing rain: A bit of a wild card factor; this has a chance at going up or down.





Wintry precipitation will cause travel problems such as slick roads and sidewalks. In areas with freezing rain, scattered power outages are also possible.

A flood watch is also in effect for eastern MA, for possible flooding of urban areas. Do not drive your vehicle where water covers the road; heavy rain will impact tomorrow’s commute.

Strong winds – northeast 20-40 mph with gusts of 45-65 mph – may cause difficulties as well, including perhaps some tree damage and isolated power outages. Wind advisories are in effect (with high wind warnings for Cape Ann as well as coastal southeast MA).


Precipitation type across north-central and western MA is still a question, and slight temperature differences at various atmospheric levels – mainly the low levels – could make a major difference in precip type and associated impacts.

Also for precip type, the HRRR depicts mixed sleet and rain well into the rush hour north and west of Route 95/128 in Massachusetts. If a similar scenario verifies, the sleet would be an added mess to already heavy rain. Nonetheless, school delays in northeast MA are still highly unlikely, but this is the wild card factor for northeast MA.

School Impacts

School impacts appear likely well inland, in the 3-6″ snow/sleet area as well as the freezing rain area. Impacts appear unlikely for central MA, and very unlikely for northeast MA, with Boston and points south having practically zero chance of anything. Everyone please do your homework, though, even if it seems likely.

All in all, use caution and stay safe!

Hello! I'm Nathan Coram, a 20 year old meteorology student and weather geek, and am in 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 on Dracut Weather (also on Twitter and Facebook), helping with the UML Weather Center social media, and tweeting about the weather on my own account as well. Thanks for visiting!
