Forecast in detail
Temperatures jump around this week but, on balance, are milder than they were the week before. Today, highs should top 50 degrees, before settling back down closer to 40 Tuesday and 45 Wednesday. But as we lean in to 2021, temperatures shoot back up, returning to the 50s on New Year’s Eve and into the 60s on New Year’s Day. As we warm up Thursday and Friday, we’ll also see frequent showers but dry out in time for the weekend.

Today (Monday): We may awaken to a good deal of cloud cover as a cold front slides through, but we should see increasing sunshine by the afternoon. Cold air is slow to follow the cold front, and highs should still top 50 in many areas. Winds are from the southwest and west at about 10 mph. Confidence: Medium-High

Tonight: Skies are mostly clear, and chilly air spills back into the region. Lows range from the upper 20s to low 30s, with winds from the northwest at 5 to 10 mph. Confidence: Medium-High

Tomorrow (Tuesday): A bright and sunny but cold winter’s day. Highs should climb to around 40. Winds from the northwest around 10 to 15 mph make it feel several degrees chillier. Confidence: High

Tomorrow night: The coldest night of the week under clear skies and light winds. Lows range from the upper teens in our colder spots to the mid- to upper 20s downtown. Confidence: High

December 29, 2020
December's full Moon rises on Tuesday, December 29, 2020.

WHEN TO SEE DECEMBER’S FULL MOON
December’s Cold Moon reaches peak illumination on Tuesday, December 29, 2020, at 10:30 P.M. EST.

Start looking for the full Moon just before sunset as it begins to peek above the horizon. To find the exact time that it will appear in your area, consult our Moonrise Calculator.

What makes this full Moon special? It’s most distinctive for its high trajectory across the sky, which results in the full Moon sitting above the horizon for a longer period of time.

WHY IS IT CALLED THE COLD MOON?
The Moon names we use in The Old Farmer’s Almanac come from Native American, Colonial American, or other traditional sources passed down through generations. A variety of Native American societies traditionally used the monthly Moons and nature’s corresponding signs as a calendar to track the seasons.

Today, December’s full Moon is most commonly known as the Cold Moon—a Mohawk name that conveys the frigid conditions of this time of year, when cold weather truly begins to grip us.
