The coastal storm that brought the heavy snow overnight changing to a wintry mix and then to rain in some locations early this morning is pulling away and will streak toward eastern Canada today. Behind the storm much colder air is already moving in bringing a flash freeze to the area. Where temperatures climbed above freezing for several hours this morning have already begun to see the mercury drop back into the 20s very quickly during the mid morning hours, especially north of the city.
Local snow accumulations ranged from just over 4” in Winthrop to 10” in Topsfield. A few other totals were 5.5 inches in Saugus and north Beverly, 6 inches in Lawrence, 6.5 in Gloucester, 9.5 in Wakefield, with generally 8 to 10 inches between the Route 128/95 belt westward to the Route 495 communities. As expected areas right along the immediate coast saw lesser amounts.
Freezing drizzle will be an issue for a time through the remainder of the morning and we could see a few more flakes before the precipitation winds down early this afternoon. Winds will turn northwest and continue to usher in colder air through the remainder of the day. Roadways will become more slippery given the sudden temperature drop as road crews work to clear, salt and sand them.
Temperatures plummet into the teens tonight as skies become partly cloudy and then mostly clear by morning. A hard freeze will result and any snow and ice not removed today will be rock solid hard overnight and Monday morning.
Although high pressure pays a visit Monday the temperatures remain frigid through the day despite sunshine. Brisk winds will make it feel even colder than the actual temperatures as mid Winter conditions prevail and we remain much below normal in the temperature department.
The drier air will not last long as another low pressure system will likely bring us a round of snow again on Tuesday and Tuesday night. Accumulating snow is most likely across eastern Massachusetts but not likely to be as significant as some of the totals mentioned above. It does bear watching however and if it should intensify quickly then we could see higher snow totals. An early estimate is 3 to 6 inches but that is subject to change. The Tuesday evening commute could be a messy one.
