BOSTON — It’s a cold morning across the region with temperatures in the single digits and even a couple degrees below zero across the north. West of Route 128 this morning there is a wind chill advisory until 10 a.m. You can expect it to feel well below zero through mid-morning. Actual temperatures remain in the 12 to 17 degree range.
The cold continues overnight with similar temperatures and a slight breeze. At cold levels like this, only a 5 or 10 mile per hour breeze can bring temperatures below zero quickly. I expect lows to fall below zero in a few spots and end up around 6 or 7 at Logan Airport.
Friday is still cold with highs only 10 to 15. Across the southern part of Cape Cod and the islands, highs will reach the upper teens to near 20.
On Saturday, the winds will flip direction and come more from the south. This will bring milder air to the area for a few hours. Highs will reach the upper 20s to mid 30s, and it will feel like spring after this cold shot. Don’t get used to the milder conditions because they aren’t going to last long. A front will cross the area during the afternoon and bring a bit of snow. While this won’t be a big system, roads could become slippery as the snow accumulates a coating to 1 inch.
The snow ends early Saturday evening before it becomes colder again on Sunday. A quick burst of snow may occur Monday morning. As this system exits the region even colder air will move in for next week.
Thursday: Partly sunny and cold. Highs of 12 to 17 (near 20 in Nantucket).
Thursday Night: A few clouds, but otherwise clear. Lows -5 to 8 (10 to 15 on the Cape and islands).
Friday: Mostly sunny. Very cold. Highs of 9 to 15.
Friday Night: Becoming cloudy. Lows in the single digits.
Saturday: Snow showers with highs likely in the lower-to-middle 30s. Some ran could mix in Nantucket.
Saturday Night: Snow showers end. Cold with a low of 8 to 15.
Sunday: Mostly sunny with highs 18 to 25.
Monday: Early snow showers, then partly sunny with a high of 28 to 34. Colder much of next week.
