A Canadian high pressure system is building into the Clarksville area today and tomorrow bringing slightly colder temperatures. A storm system currently over the southwestern United States will begin to move eastward into middle Texas tomorrow and into the southeast on Christmas Eve. At the same time a weak system will also move in situ with the system in the southeast through the middle of the country. As the system from the southwest redevelops over the southeast colder air will be brought into the Clarksville area. This cold air coupled with any precipitation will cause this precipitation to fall as snow. Sleet may mix in at the onset during Christmas Eve, but it will eventually change to all snow overnight. Here are the 6am model outputs for the potential Christmas Eve storm.
All three models, the GFS, WRF, and Canadian, bring scattered snow showers to the Clarksville area overnight Christmas Eve. All models also indicated that the precipitation will mostly be in the form of light snow showers throughout the overnight. The storm system that will bring most of the moisture into the Clarksville area will remain further south than what the models indicated yesterday. The location of this storm system by all models is in the Gulf of Mexico, starting to form near Houston, TX and moving east. With a southern track to this storm, less precipitation is expected in the Clarksville area. Most of the snow that will be seen will be with a weak system that is picking up some of the moisture from the southern system that will pass through Christmas Eve night. A large dome of cold air will dig into the southeast on Christmas bringing more cold air into the region for the weekend and the beginning of the upcoming workweek.
Clarksville Weather Examiner currently expects scattered light snow showers to begin over the Clarksville area at about 8pm Christmas Eve and last till about noon time on Christmas. Clarksville Weather Examiner is currently predicting a dusting to 2 inches of snow from this system, mainly on colder surfaces. Driving overnight Christmas Eve into Christmas may become difficult as wintry precipitation falls. Please allow extra driving time during Christmas Eve and Christmas if you have to head out in the snow.
Clarksville Weather Examiner will continue to follow the upcoming potential snow storm as more information is gathered and Friday approaches. Clarksville Weather Examiner can be followed on Facebook on the page Clarksville Weather Examiner or on Twitter at ClarkWxExaminer.
