INDIANAPOLIS — Today wasn't close to the sunshine we enjoyed over the weekend, but temperatures remained over 10 degrees above average for mid-December. Indiana is in between a cool front that helped bring the widespread rain last night and a stronger front that eventually brings snow bursts with much colder air on Wednesday. A quiet evening in central Indiana now but we'll be monitoring visibility closely overnight into Tuesday morning with the potential of locally dense fog developing in the relatively saturated, unseasonably moist airmass.
It's too early to say how widespread it will be and whether or not Dense Fog Advisories will be needed. But you should be aware that pockets of near-zero visibility and/or some school districts on delays Tuesday morning is a possibility. Check with Angela Buchman this evening and Lindsey Monroe early in the morning on 13 Sunrise for the latest.
Temperatures Tuesday again peak near 50° (except in southern/southeastern Indiana where clouds may be thicker) before the stronger front sweeps through the state on Wednesday. The cold air advection with the boundary is expected to at minimum trigger scattered to numerous flurries/snow showers and at worst may set-off heavier snow bursts and/or a few squalls. There's a high deal of uncertainty on whether the latter does materialize.
But we'll monitor for updates and some slick travel for the Wednesday evening/Thursday morning commute is fair game. That holds true regardless of how much snow falls due to the rapid drop in temperatures quickly freezing any residual moisture on surfaces. Like last week, windchill temperatures Thursday morning bottom-out in the -10 to near 0 degree range to make it "feel" 60+ degrees colder than the unseasonably warm highs Sunday, today, and what's ahead Tuesday.
This shot of cold will be brief. After Friday morning, when lows drop into the teens, temperatures beginning elevating again and reach the mid-40s this weekend. Please check back for updates.
