Hi everyone, We wanted to give you a heads-up about a storm that will be impacting our region Sunday night and continuing into Monday night. This will be a complicated storm with a mix of precipitation types across southern New England. *Main Weather Concerns: * 1) *Possible ice storm* in the higher terrain of western MA (eastern slopes of the Berkshires) and central MA (Worcester County hills). Freezing rain is expected to begin in those areas Sunday evening and continue into Monday evening, with temperatures around 30 degrees. Cannot rule out some freezing rain in northern CT as well. There is uncertainty at this time as to amounts, but current projections are for between 0.25 and 0.50 inches of ice accretion in the slopes of the Berkshires and Worcester hills. There is some potential for greater than 0.50 inches. A Watch may be needed in subsequent forecast issuances. 2) *Mixed bag of snow, sleet, freezing rain, and rain during the morning commute on Monday. * Any snow on the front end in northeast MA is expected to be short-lived and turning over to sleet and rain Sunday night into Monday. The worst conditions are expected to be outside of the I-495 corridor. On Monday, mainly rain is expected in the CT River valley, northern CT, RI, and eastern MA. *Confidence...and what could still change:* We have high confidence that this storm system will occur and produce a wintry mix, but still low to moderate confidence on amounts and distribution of precipitation types. A colder scenario than currently forecast would mean less freezing rain and possibly significantly more sleet and/or snow in northeastern MA. The potential exists for higher freezing rain totals in the high terrain of western and central MA, which, if true, could lead to power outages and downed trees/wires. Stay tuned for the latest information. -- Glenn Field Warning Coordination Meteorologist NWS - Boston/Norton, MA If you have any questions or would like more information, don't hesitate to contact us via this email address, on NWSChat <https://nwschat.weather.gov/>, or at the following: National Weather Service Boston/Norton, MA 46 Commerce Way Norton, MA 02766 508.622.3280 Website <http://www.weather.gov/boston> | Facebook <http://www.facebook.com/NWSBoston> | Twitter <http://www.twitter.com/NWSBoston>
