Good evening Tennessee Valley and a very happy Sunday! A perfect Sunday afternoon that I hope everyone was able to get out and truly enjoy. It’s not very often that we see a January day with sunny skies and temperatures in the mid-60s. Tonight will be generally quiet and unseasonably warm with lows only dipping down into the low and mid-40s despite clear skies and calm winds. I think the winds out of the south will be our saving grace in that department. Keep in mind an average low is 31 or 32 degrees.
From here we can turn our attention to Monday and Monday night. There is a developing system to the northwest that will gradually move east. It’ll take its time though so most of the day looks again to be pleasant with high temperatures again in the low 60s across much of the Tennessee Valley also featuring mostly sunny skies with increasing clouds through the afternoon. Now with this low that is well north this is also an associated cold front. That cold front is expected to come through the Tennessee Valley Monday night and early Tuesday morning. Ahead of this front is a small opportunity for a few light showers. Generally I expect the majority of us will be dry by the time you head out for work and school Monday morning.
While the cold front will come through Monday night and Tuesday morning, we wont feel much of a change until Wednesday. 850Mb maps had no problem allowing CAA to control the forecast. This will prevent temperatures from getting much higher than the mid-40s on Wednesday, and the GFS was even suggesting that high will occur around 06Z. From there CAA keeps high temperatures in the low 40s for highs and dipping down in the upper 20s for lows through the remainder of the week. The best part about the extended forecast would be the sunny skies expected Wednesday and Thursday.
With an advancing system clouds will increase Friday through next weekend. The only chance of rain comes Saturday, but models are terribly different at this point so that’s all I’ll say on that.
