Merry Christmas from the Weather Center. Rain chances will be going down during Christmas morning and some peeks of the Sun in the afternoon are possible with high temperatures of 65 to 70 around East Tennessee . Yet another rain system will move into our area by Monday night with some Colder Weather arriving by the end of the week, high temperatures in the upper 30s on Friday. We still do not have any major winter weather in sight for the next 10 days. The national high temperature on Christmas Eve was 90 in McAllen Texas and the low was 18 below zero at Stanley Idaho.
