A storm system will affect Southern New England tonight through early Sunday Evening. The headlines depict the current thinking on storm impacts. There are few key factors that will bear watching with this storm system and they are as follows:
1.) There could be a period of freezing rain in Northwest and North-Central Massachusetts. Just a small amount of freezing rain can result in higher impacts with respect to travel conditions. Also, the recent extreme cold conditions may allow for the rain to freeze on contact even with temperatures slightly above freezing given the extreme cold of the past few days and the fact the precipitation will fall during the evening.
2.) The storm system has been trending a bit stronger in recent runs and this could affect wind and coastal flood potential as well as the extent and locations of the heaviest rainfall. This will bear watching as we approach the storm event.
SKYWARN Self-Activation will monitor the storm system for tonight through Sunday Evening. Another coordination message will be posted by 7 PM this evening.
