Warm through tomorrow, then rain and big weather changes arrive.
It's a very warm afternoon across the Tennessee Valley, with temperatures for almost all of us well up into the low to middle 70s. Clouds eroded earlier in the day, and this has allowed for a good bit of sunshine, maybe even a little more than we originally expected for today. We have one more warm day ahead of us before all this changes...
Southerly winds and increasing cloud cover late during the overnight will help to keep temperatures from dropping out of the mid 50s or so as we head toward daybreak on Wednesday. Then, the southwesterly winds really crank up during the day, sustained at 10-20 mph with gusts to 25-30 mph possible, and this with some added sunshine will once again boost afternoon temperatures into the low to mid 70s areawide. Clouds will be on the increase ahead of the next front as early as the evening hours, however.
Showers work into the area during the late night hours of Wednesday night and through the morning to midday hours of Thursday as the cold front moves in. Gusty northwest winds will bring in much cooler air once again, with highs on Thursday only reaching the mid 50s. Skies clear during the evening, and as winds begin to lighten overnight, we look to drop into the upper 20s and lower 30s by daybreak on Friday. Some locations may be as chilly as the mid 20s in the outlying rural areas. By afternoon, despite wall to wall sunshine, temperatures in the afternoon only peak in the lower 50s. By the weekend, temperatures moderate a bit as high pressure shifts eastward and winds once again become more southerly. Still, after Wednesday, it appears we do not see a return to "warm" weather through the next seven days.
