Today is a comparatively cool end to a month of seemingly unending warmth. Tonight’s festivities are nice and dry but heavier coats need to come out as chillier air is finally making its big move into the area. At least it’s more seasonable for a change which will certainly feel cold to us after being spoiled all December. Sunshine is also more dominant for a welcome change through the holiday weekend.
New Year’s Eve (Thursday): Drier air gradually filters in on fairly gusty northwest winds (up to 20-25 mph or so). Clouds begin to show breaks in the morning and there should be quite a bit of sun by afternoon. Most areas still reach the low-to-mid 50s but it takes a little more work as cold air pours in from the Midwest. Confidence: Medium-High
Tonight: The mad dash to all those expensive tables to dinner should be uneventful as winds lighten up and dry air dominates. Temperatures slip through the 40s in the evening but for those determined to see in the New Year it is likely to be slipping into the 30s in all but downtown. Lows range through the 30s. Confidence: High
New Year’s Day (Friday): 2016 gets off to a fine start with highs mainly in the mid-to-upper 40s with plenty of sunshine. Breezes are light helping to keep the chill factor down. Not a bad day to be out and about unless you are a football fan hunkered down on the couch! Confidence: High
Tomorrow night: The starts shine brightly in a notably colder environment. Still it is no worse than seasonable levels with lows in the mid-20 suburbs to lower 30s downtown. Confidence: High
Saturday has bright sunshine going for it; in fact we are at our closest point to the sun in our orbit! Not that it does us much good as highs only reach the low-to-mid 40s. High pressure settles in for the night and the clear skies allow temps to slip down to the low 20s outside the beltway but still near freezing downtown. Confidence: High
Sunshine remains a great new friend in the New Year as Sunday sees barely a cloud in the sky and mainly calm winds. Highs reach the mid-to-upper 40s. Another seasonably cold night brings lows in the mid-20s to lower 30s across the area. Confidence: High
Monday starts out calmly but things go downhill in a hurry with strengthening north winds getting strong by afternoon. Highs in the low-to-mid 40s are still likely by noon but fall rapidly as Arctic air moves in for a very brief visit. Confidence: Medium
