Unusual Warmth for Now; Much Cooler this Weekend
This kind of Fall warmth is not unheard of, but it is a little unusual. If you don’t like the heat, don’t worry. It goes away by the weekend behind a strong cold front. Temperatures soar into upper 80s to near 90 degrees on Wednesday and Thursday afternoons, so it stays hot in the short-term!
A few isolated showers and storms develop on Thursday afternoon and evening (mainly west of I-65), but our best chance of rain comes late Thursday night through Friday morning.
Late-Week Rain: Showers on Thursday will be widely separated, but they could still briefly become heavy. More widespread rain and thunderstorms move in after dark. There is not much risk of severe weather with this system, but an isolated strong/briefly severe storm is not impossible as the front moves into The Shoals Friday morning.
Rainfall will vary greatly from place to place; a few communities around The Shoals could see as much as 1.25” of rain. It tapers off as it moves east because the best “dynamics” will be passing north of us as the front moves through. That tends to cause a weakening trend in precipitation.
Friday Night and The Weekend: What a change for the weekend! Rain ends on Friday evening before Football Friday high school games get kicked off, the wind shifts to the northwest, and it will get cool! Temperatures fall off into the lower 60s by game time; that northwest breeze means it is jacket weather for the first time this season as the mercury keeps dropping through the 50s during the games.
Saturday and Sunday look fantastic and much cooler! Expect a high near 70ºF on Saturday after a chilly start in the 40s. Sunday looks a bit milder with a few more clouds; temperatures rise into the mid-70s in the afternoon.
Looking Toward Next Week: Another front slips through on Monday with some spotty showers; that reinforces the cool air in place. Expect more pleasant Fall weather next week: highs in the 70s to near 80 degrees and lows in the 40s and 50s.
