High pressure near the Arkansas-Mississippi-Louisiana border is supplying a fresh shot of cool air on a light northerly breeze. The temperature dipped to freezing very briefly this morning in Valdosta and Homerville, but enough high clouds prevented the mercury from getting to the magic 32 degree mark everywhere else. Cirrus clouds will filter out the sunshine on occasion this Christmas Eve, but temperatures will barely get to 60 degrees. A fairly vigorous upper air disturbance over the Texas Panhandle will approach us on Christmas morning. It will drag even more cloud cover into the area tonight into Christmas Day, but moisture in the lower part of the atmosphere will be lacking. The only area that stands a chance to see light showers is the Suwannee Valley, where a northeast flow from the Atlantic could drag in just a little bit of lower layer moisture. Once the disturbance bypasses us, skies will clear Christmas night and Wednesday morning. Our confidence in this clearing trend is higher than yesterday, so we now anticipate a light freeze and frost to greet us first thing Wednesday with very light or calm winds. Temperatures will gradually moderate starting Wednesday afternoon and we should reach or exceed 70 degrees by Friday. By the end of the week, we'll be watching a cold front approach the Tennessee and lower Mississippi Valleys. A shower could sneak into parts of Southwest Georgia well ahead of the front on Friday, but the front will be a slow mover. Most likely, we'll have to wait until this upcoming Sunday to see a better chance of rain showers.
This will be my first Christmas with my family in 4 years, so I'm very excited about that! To those of you who read this blog and our loyal viewers, I personally wish you a very Merry Christmas!
