Temperatures will dip fast as the sky is clear tonight so expect the low 30s this evening with wind chills in the low 20s. Our high-resolution model hints that low clouds/freezing fog may develop but will be patchy like it was Saturday morning. As we go into Sunday, I'm tracking a trough of low pressure that will come down across northern Indiana. This will allow colder air to build back in with the chance of some flurries. The best chance of light snow will be to our north and east with lake-effect snow farther north.
As the trough deepens overhead, snow showers will be with us on Monday. Still, the best chance of snow is to our north and east but I can't rule out some snow in Indy. Little to no snow accumulation is expected for central Indiana although places like Logansport, Peru and Marion may see up to 1 inch of snow through Monday.
Temperatures will stay in the low 30s these next few days with some of the coldest air since late November moving in Tuesday morning. Lows will dip to the upper teens under a mostly clear sky.
The warming trend will begin Wednesday with highs near 40 degrees and low to mid-40s continuing into next weekend.
Long-range models show rain Friday and rain early Saturday before colder air moves in and possibly brings a wintry mix. The pattern looks like it becomes a bit more active around January 8. We'll watch closely! --Danielle Dozier
