Let’s get to the potential for snow flurries first in the Tennessee Valley. It’s several days away, but it’s looking more and more like someone will see snow flakes later next week. First, rain is in the forecast Tuesday. As cold air wraps around the system, the rain changes to a brief period of light snow or flurries early on Christmas Eve (Wednesday). Little or no accumulation is expected at this time. If anyone sees a dusting it would be in the usual areas like Lookout Mountain and the northern Cumberland Plateau. Mentone and Sewanee to name a couple of spots. **Again, we are several days out, and no problems are expected. Check back for further updates.**
Here is what guidance looks like right now. First the GFS.
Late Tuesday Night Into Early Wednesday Morning
Precipitation (green) holds on across central and east Alabama. The blue line is the freezing line. Everything along and west of that blue line would be in the form of snow. Drier air moves in very fast though. You can see it’s already dry over the Shoals at this time.
Here is a look at the European Model:
Early Wednesday Morning (6am)
This shows cold air across all of the area. We are west of the blue line.The lighter shade of green shows precipitation ending at that time. We are in the 0.05″ to 0.10″. That is mainly in the form of rain, but there is cold air in place. Looking at this, light snow/flurries are possible Wednesday morning.
Friday afternoon, we top out in the middle to upper 40s under a cloudy sky. The rain totals are not only for this weekend, but through the middle of next week. Only expect a tenth of an inch or so tonight into Saturday. Steadier rain is in the forecast next week.
