We are dealing with lots of rain today as temperatures drop. The heaviest rain falls in South Central KY today and tomorrow, so minor flooding is possible there in flood prone areas. After midnight, sleet could mix in with rain. Freezing rain is a possiblility overnight, so icy roads (especially bridges and overpasses) could be a problem tomorrow morning and afternoon.
The NWS Louisville just updated the Winter Storm WATCH/WARNING map to include Louisville in the WARNING starting tonight at 10PM.
Ice accumulation is a concern for tomorrow, and the ice may cause more problems than the snow accumulation. The roads will be difficult to salt with so much rain moving through ahead of time. Travel toward Evansville, Paducah or Southern IL is not advisable tomorrow.
Here are the latest snow accumulation models: NAM, EURO, GFS, RPM
This is the current WAVE 3 Snow Totals map.
