Today (Wednesday): The truly bitter blast isn't here quite yet. But it is still the cold day of the 20s – and afternoon highs in the upper 20s to mid-30s. Winds crank up afternoon, gusting to near the west-southwest, with wind chills in the teens to low 20s. Partly sunny morning skies turn cloudy late morning into the afternoon, when a few snow showers could put down a quick coating in spots. Confidence: Medium-High
Tonight: Winds should be from the northwest, evening breezy as skies turn mostly clear. The bitter cold and dry air in the evening is like a rock through the 20s and teens. Most spots should be lows in the single digits, maybe all the way down to the bottom of our coldest, and holding up near 10 degrees downtown. Winds diminish overnight, but still just enough of a breeze. Confidence: High

Tomorrow (Thursday): We've got plenty of school delays again, and maybe some cancellations, as well. A relatively light breeze, about 10 mph from the west, is enough to keep winds down in the morning. Low-to-mid 20s is the best we can do afternoon highs, with the lingering breeze keeping in the teens and single digits. Confidence: Medium-High
Tomorrow night: Increasing clouds should prevent us from getting as cold as tonight. But we're still talking very chilly lows ranging from the 20th to the 20th. Confidence: Medium-High
A LOOK AHEAD
Friday skies are mostly cloudy as a bit of energy. If there 's any accumulation, it' s supposed to be more than a dozen. Anything that falls would stick, though, with highs in the mid-20s to low 30s. Partly cloudy Friday night with lows in the mid-teens to low 20s. Confidence: Low-Medium
High pressure dominates Saturday into Saturday night with partly clear skies and light winds. Saturday highs should reach in the mid-30s to low 40s, before Saturday night lows fall back into the 20s. Sunday should continue to be in the 40s to near 50s. Confidence: Medium-High
