Weather Summary:

We are tracking a weak disturbance in the StormTrack 5 Weather Center. This disturbance is showing signs of washing out, but could still bring a 20 percent chance of a stray shower or sprinkle today. The showers chances are better just west of the Tri-Cities.

The clouds have been hanging tough and will stick around tonight as well. We will be cold for most of the area tonight.

Friday will be a partly cloudy day with temperatures near where we would expect for late December.

StormTrack 5 meteorologists are tracking a system developing along the Gulf coast. That low will track mainly south of our region and then east of the southern Appalachians. Rain chances will increase Friday night to 50 percent and 70 percent on Saturday. You should be on the alert for possible snow showers in the higher elevations on Friday night with near freezing temperatures.

Most areas will see only rain with this system as the freezing temperatures will be higher in the atmosphere.

Sunday and most of Monday will be partly cloudy. We could see a few late day or nighttime showers arrive on Monday. This is a strong storm system that will head for our area from the Rockies and southern Plains. We will see rain on Tuesday with a 40 percent chance.

Wednesday is Christmas Eve and we will see some colder temperatures arrive with moisture in place. We will have a rain and snow mix or possibly snow showers. This may create a big travel concern for the northeast and New England states. As for our area, the models have struggled the the timing on the cold air arrival and push.

We are tracking this system for the holiday and will keep you updated as we head for Christmas week. You should consider the possibility of slippery travel and an be on the alert for mid-next week if you are traveling north and northeast for Christmas.
