Disclaimer: These are long-range weather model maps, and subject to change:
This first image below is Christmas Eve. It you have any travel plans this coming weekend through Christmas Eve, it looks like you're in good shape. High pressure will have enough control to keep our area mainly dry on Christmas Eve with temperatures staying pretty cool in the 40s.

The next image here is Christmas Day. A storm is brewing to the west, and the GFS and EURO long-range models are both hinting at this storm developing - however, it should stay west of us through Christmas Day.
(Christmas Day Map)
The image below shows that storm now strengthening with a deep area of low pressure to our north. This could bring bouts of heavy rain, and perhaps snow showers on the back end of the system on the 26th or 27th. The models have been flip-flopping on this system a bit, but generally the 1-3 days after Christmas could be unsettled with rain/snow chances.

The final map is also on the 26th, showing the Critical Thicknesses. This is a little inside baseball, but basically those lines represent where the changeover from rain to snow could occur. Notice the lines dropping down to Kentuckiana, behind those lines is much colder air. This shows that if we have a storm system moving through, it could bring some snow showers on the backside. Of course, we'll keep fine-tuning the forecast over the next several days. Stay tuned!
