Patchy freezing drizzle is possible Monday evening for areas northwest of Boston.
A light glaze of ice accumulation and light snowflakes will create new slick spots on the roads through about midnight for especially southern and central New Hampshire and Downeast Maine. Boston and areas southeast will continue to have light patchy drizzle, but temps don't drop to freezing until after midnight, and by that time, we should dry off a bit.
Dryer air returns for the late overnight forecast, but still, some icy spots could linger as temperatures drop to the 20s and low 30s north and west by daybreak.

Friday night is clear and very cold, then a storm impacts New England on Saturday with heavy snow developing in the afternoon and evening, changing to rain along the south coast at night. Otherwise, snow will end early Sunday, becoming windy and staying cold. Where it is all snow, we may have more than 10 inches, then it is very wintry as seen here in our First Alert to 10-Day Forecast.
