FORECAST IN DETAIL


Today (Wednesday): Steadier early-to-mid morning rain should taper thereafter. But occasional showers or drizzle may linger into early afternoon. The sun remains mostly a no-show, with overcast ruling the skies one more day, except maybe some late-afternoon peeks of sun. Between the clouds and the dampness, highs in the low-to-mid 40s feel rather chilly. Confidence: Medium-High

Tonight: Breezes from the west and northwest try to dry out the air just a bit. Most everyone should see lows in the 30s - ranging from the low-to-mid 30s in the suburbs to the mid-to-upper 30s downtown - under mostly cloudy skies. Confidence: Medium-High

Tomorrow (Thursday): Models have trended north with the next storm system, which initially looked like it would stay to our south. That means we’re now facing a 50-60% chance of snow, sleet and/or rain, mainly midday into evening. With highs only in the upper 30s to low 40s and temperatures lower than that during any heavier precipitation, minor snow and/or sleet accumulations are possible, especially on grass and side roads. It’s also possible the northward trend reverses back to the south, leaving us with little in the way of precipitation. We’ll update later today as new model information comes in. Confidence: Low

Tomorrow night: That chance of snow, sleet and/or rain lingers into the evening before skies clear overnight. Colder air moving in behind the storm drops our lows to the mid-20s to low 30s. Confidence: Low

A LOOK AHEAD

Partly to mostly sunny skies provide a nice change of pace for Friday, but they are courtesy a cold high-pressure system that caps highs in the low-to-mid 40s. Friday night lows find their way back down to the mid-20s to low 30s. Confidence: Medium-High

The weekend starts off nicely on Saturday as flow from the southwest brings a substantial bump in temperatures with highs in the 50s, followed by not-too-cold Saturday night lows in the 30s. Sunday is shaping up as breezy and a bit cooler with highs in the mid-40s to near 50. Both days should feature partly to mostly sunny skies. Confidence: Medium

Inauguration Day still looks cold with highs in the 30s to near 40 and the potential for afternoon flurries. Confidence:Medium
