More humidity and a few showers and storms in our near future
It’s another cool start in the Tennessee Valley with some patchy fog in spots. This is the last really comfortable morning we get for a while. A hotter, more humid air mass edges into the Tennessee Valley today and Friday, and that means we have a chance of some hit-or-miss, pop-up, brief afternoon showers and thunderstorms.
Today’s chance of rain is tiny: only about 10% at best east of I-65. That chance of rain increases to the 20-30% range in Northeast Alabama Friday; fewer showers (if any) occur around The Shoals. Expect highs in the upper 80s and lower 90s through the rest of the week, and with higher humidity, it feels a lot less like September and a lot more like August to end the month!
Tropical Storm Erika: Tropical Storm Erika strengthens and moves northwest in coming days; that could put the storm near Florida’s East Coast by Monday as a hurricane. See the latest track and statistics on Erika at valleywx.com.
Football (Thursday and) Friday: Humidity increases Thursday, but the weather still looks very nice for high school football. Temperatures hover in the 70s for Thursday night games, and rain stays away for one more night. Friday night games look a little more uncomfortable: warm, muggy, and a few isolated showers and storms. Kick off temps on Friday will range from 80-85ºF; the best chance of a brief shower is east of Interstate 65.
The Weekend: Saturday and Sunday look hotter and more humid with some scattered showers and storms. A few of those storms could be locally heavy, but the rain does not appear to be very widespread either day.
A weak upper air low overhead this weekend helps enhance that chance of scattered storms, but we still do not expect them to be as widespread and heavy as last weekend.
Hotter next week: Summer is not over yet! Wednesday, September 23rd is the official start of Fall (Autumnal Equinox), and there is a lot of hot weather to go. High temperatures soar back into the lower and middle 90s next week, and higher humidity makes it feel hotter than that. There is some uncertainty about how Erika will play into the weather around here late next week; odds are that we stay hot and dry, but we may have to do some adjusting.
