Skies are mostly sunny across the Tennessee Valley on this Monday as we continue to enjoy this quiet weather pattern. Afternoon temperatures are topping out in the low to mid 80s, with comfortably low humidity. It's a great day to get outdoors for chores, to eat lunch on the patio, or for any outdoor activities... including the Middle Tennessee District Fair that's ongoing this week in Lawrenceburg.
Skies will stay mostly clear into the evening, with temperatures dropping into the upper 60s and lower 70s as early as just before sunset. Temperatures continue to drop overnight but level off a little bit before daybreak as clouds increase a bit. This may keep our overnight lows closer to the upper 50s and lower 60s. Tuesday looks to have a little more in the way of cloud cover, but still plenty of sunshine, with highs once again topping out in the low to mid 80s.
As we head into the middle and latter half of the week, moisture starts to creep in from the west as we get more of a southerly flow on the back side of high pressure as it breaks down and shifts eastward. This lets a disturbance over the Plains and Lower Mississippi Valley inch a little closer to our immediate area. We will start to see an increase in cloud cover (but still some sun each day), and the chance of a few spotty showers will begin to return to the forecast as well. This will begin as early as Wednesday and then last through the forthcoming weekend and into early next week. We don't see any widespread or heavy rain ahead for our area, but it looks like we will be dodging a few showers at times.
Without any big fronts or storm systems moving through the area, temperatures won't change much for the next several days either. Afternoon highs look to stay in the low to mid 80s each day from now through the weekend, with overnight lows between the upper 50s and lower 60s. There are some signs that another cold front may approach the area during the first half of next week, dropping afternoon temperatures back into the 70s and morning lows into the lower 50s.
Meanwhile, as we enter the last few days of September and get ready to head into October on Friday, we're starting to notice the first signs of that in parts of the area. Minimal leaf changes this week are starting to show up generally near and east of the I-65 area of middle Tennessee into north and northeast Alabama. Don't be surprised if you start to see a few isolated golds, yellows, oranges, and reds, mixing in on the hills in portions of Maury, Marshall, Giles, and Limestone Counties in the days ahead. We will gradually see that continue to overspread the area over the coming weeks, with the fall foliage peek for our area generally being near or just after Halloween.
