Just rain for Louisville area.
Fairly weak disturbance working northeast will push through the area tonight. As often, we’re near the borderline between rain and snow. As moisture increases this afternoon a few spots of very light snow/sleet/rain will probably develop over southern Indiana.
Larger area of rain/snow will probably move to the I-65 corridor by 7-8 P.M. At onset, some snow and/or sleet may mix in, but will quickly become all rain for most of the night around Louisville. Any snow of a half inch or more should be at least 30 miles north of Louisville. But, total snowfall could easily reach 2″-4″ over central Indiana.
Tonight’s precipitation event is part of a much larger storm system that will bring us heavier rain late Monday and Monday night. As the system moves east, the rain could change to the period of light snow early Tuesday.
Today’s GFS predicts unseasonably warm weather for most of Christmas week. Temperatures could reach the 60’s at least a couple of days, including Christmas Day. No White Christmas this year.
