Storm Coordination Message #1 – Late Monday Night 11/19/18-Tuesday 11/20/18 Winter Storm Potential

Hello to all…

..Another round of accumulating snowfall is expected for northwest and north-central Southern New England overnight into Tuesday. As we approach Wednesday and into Thanksgiving, bitterly cold temperatures will grip the region with strong winds and the possibility of snow squalls in localized areas Wednesday Afternoon and Evening..
..A Winter Weather Advisory from 10 PM Monday Night through 5 PM Tuesday Evening for Franklin, Western Hampshire, Western Hampden, Northern Worcester and Northern Middlesex Counties of Massachusetts for 2-4″ of snow with isolated higher amounts of up to 6″ in higher elevation locations. Some sleet and freezing rain may mix in with the snow during the day Tuesday..
..Areas outside of the Winter Weather Advisory area north of the Mass Pike may see a coating to 2″ of snow accumulation with mostly rain occurring in these locations and pretty much all rain south of the Mass Pike..
..SKYWARN Self-Activation with Amateur Radio Net call-ups will monitor snowfall reports and changeover in precipitation type for Tuesday. SKYWARN Self-Activation will monitor the strong winds and localized snow squalls for Wednesday Afternoon and Evening..

Another round of accumulating snowfall is expected in northwest and north-central Massachusetts as another storm system will have just enough cold air in place to allow for this to occur. The headlines depict the latest thinking for snowfall late Monday Night into Tuesday.

As we look ahead to the busiest travel day of the year on Wednesday and into Thanksgiving, travelers will need to be on the lookout for localized snow squalls that may impact travel in isolated locations as well as strong wind gusts up to 40 MPH. In addition, bitterly cold conditions more like mid-winter will affect the region Wednesday Night into Thursday so dressing in multiple layers will be essential for any outdoor activities. Future coordination messages will detail weather conditions for Wednesday into Thanksgiving.

SKYWARN Self-Activation with Amateur Radio Net call-ups will monitor snowfall reports and changeover in precipitation type for Tuesday. SKYWARN Self-Activation will monitor the strong winds and localized snow squalls for Wednesday Afternoon and Evening. This will likely be the only coordination message for Tuesday’s storm system unless a significant upgrade occurs and time allows for an update. Another coordination message focusing on the weather for Wednesday into Thanksgiving will be posted Tuesday Evening.
