This weekend’s cold weather is the appetizer to the main entree of bitter cold ahead for the middle of next week. As the Arctic front arrives, rain may change to snow from west to east through Southern New England on Tuesday. The cold air charging in behind the front may be enough for a flash freeze. The cold air lagged far enough behind the precipitation during Thursday night into Friday that the pavement had a chance to dry. This may not be the case on Tuesday afternoon/evening.
Sunday looks like a fairly quiet day with some clouds and milder temperatures in the afternoon. Expect highs in the low 50s. Monday stays dry and cool, with temperatures in the low-mid 50s again. The front arrives early Tuesday in western CT and then moves east through Southern New England. Expect rain for a few hours before a possible change to snow. That change to snow could happen by midday in western CT, and will likely happen in the afternoon in eastern CT, RI and SE MA. The temperature will stay above freezing while it’s snowing, and the pavement should not be cold enough for the snow to stick very well to that. It may stick better on grass, decks, etc. Precipitation ends by late in the afternoon across Southern New England, and cold air follows very quickly behind the front.
The temperature will dip to below freezing within 2-3 hours of precipitation ending on Tuesday, and that may be enough for a flash-freeze of any water, slush, snow on pavement. Given the timing, untreated roads could get slippery for the evening commute.
An Arctic blast arrives in the midweek. It will fall all the way to the upper teens and low 20s by dawn on Wednesday. Dry weather is likely Wednesday and Thursday with highs only in the low 30s. The temperature will average about 10 degrees colder than normal in the next 7 days. The long-range outlook brings milder weather into the picture between November 17-24.
