For The Rest Of Today: Skies will be sunny to partly sunny through early this afternoon before clouds increase and lower during the mid and late afternoon hours. High temperatures this afternoon will be near 40 Degrees.
An Ice Storm Is Expected Across Parts Of Western & Central Mass From Tonight Through Monday & Monday Night: Weather Forecast Overview: An area of high pressure will be positioned across southeastern Canada tonight through Monday. The position of this high pressure is such that it will cause cold air to push southward into southern New England while milder air moves in at around 5,000 to 10,000 feet above the ground.
This setup is a favorable one for significant freezing rain and sleet accumulations across the Worcester Hills and across the Berkshires tonight through Monday and Monday night. Isolated to scattered power outages and extremely hazardous travel conditions are expected across these areas.
Elsewhere across Western and Central Mass, while a combination of freezing rain and sleet is expected tonight through Monday and Monday night, the amount of ice accumulation will not be as significant as the Worcester Hills and the Berkshires. With that said, it only takes a small amount of freezing rain and sleet to lead to hazardous travel conditions.
Details: Freezing rain and sleet is expected to overspread Western Mass and northern Connecticut between about 7 and 9 pm this evening and then overspread Central Mass by about 9 to 10 pm this evening. Sleet and freezing rain is then expected to continue throughout the rest of tonight, especially along and north of the Mass Pike.
During Monday, the precipitation type should be mainly freezing rain across Western and Central Mass. This will lead to significant impacts to the Monday morning commute and probably the Monday afternoon commute as well. The freezing rain is expected to be moderate to heavy at times leading to significant ice accumulations, especially in the Worcester Hills and the Berkshires.
Turning to Monday night, while the wedge of colder air will remain in place across parts of Western and Central Mass, a second low pressure system will be developing near the New Jersey coast on Monday night. This storm system is expected to near Buzzards Bay by Tuesday morning and then into Mass Bay and into coastal Maine towards Tuesday afternoon.
This type of storm track will eventually push milder air back into Western and Central Mass as we get into New Year’s Eve.
During Monday night, a mixture of freezing rain and sleet is likely to continue, especially in the Worcester Hills and the Berkshires while a gradual changeover to a cold rain is expected across the lower elevations of Western and Central Mass.
During the day on New Year’s Eve, an east to southeasterly wind flow will lead to all areas having a cold rain throughout the day.
Rain will come to an end by late in the day on New Year’s Eve. Colder air will filter back into the area on New Year’s Eve night leading to temperatures falling into the upper 20s. This could lead to black ice issues during New Year’s Eve night into the morning hours of New Year’s Day.
Finally, for areas that are expected to see the most ice accumulations (Worcester Hills and the Berkshires – the dark pink and light red areas on my forecast map below) should be prepared to lose power for upwards of a couple of days. Make sure flashlights and battery-powered radios and lights are working and be sure to have extra batteries on hand.
