If you've looked outside today, you've probably noticed that Mother Nature couldn't quite make up her mind. This morning's line of showers and thunderstorms weakened as it moved into Southern Middle Tennessee, and for many of us, it was more bark than bite. A few heavier downpours and gusty winds occurred, but widespread severe weather never materialized.

If you've been following my forecasts over the past couple of days, you've probably noticed that Friday's forecast has been anything but straightforward. In fact, I think "complicated" is probably the best way to describe it.

If you've stepped outside today, you've probably noticed two things. First, it's hot. Second, it's humid.

The weather across Southern Middle Tennessee is about to change in a big way. Today, we're still keeping an eye on a few showers and thunderstorms capable of producing heavy rainfall and gusty winds. By tomorrow, however, the conversation shifts dramatically as hotter temperatures and sticky humidity take over the forecast.

It's going to be a busy week across Southern Middle Tennessee, but perhaps not for the reasons you might expect. Over the next several days, we'll be dealing with a little bit of everything. Showers and thunderstorms will continue through at least Tuesday with localized flooding concerns, while by the middle of the week our attention will gradually shift toward building heat and humidity as summer begins tightening its grip on the region.

If you've stepped outside this week, you've probably noticed that something feels different. The air has been noticeably more comfortable. Mornings have felt refreshing. The sky has been a deeper shade of blue. Even afternoon temperatures in the lower and middle 80s have felt pleasant compared to what we often experience in June.

While dry weather remains in place through Saturday, shower and thunderstorm chances will gradually begin returning later this weekend and into next week. And when they do, many of the storms we'll be tracking won't be the large, organized systems we often see during the spring. Instead, they'll be the classic summertime "popup" thunderstorms that seem to appear out of nowhere, dump heavy rain on one neighborhood, and then vanish just as quickly as they formed. What makes these storms so fascinating is how short their lives often are. In many cases, a summer thunderstorm can develop, mature, and dissipate in less than an hour.

If you've stepped outside today, your first thought was probably pretty simple: "Wow, it's nice out." And you'd be right.

Temperatures are sitting in the low to middle 80s, humidity remains comfortable, and sunshine continues to dominate across Southern Middle Tennessee. On the surface, today's weather looks remarkably similar to what we experienced yesterday. But while conditions may feel nearly identical, the atmosphere is already beginning to set the stage for our next weather pattern. In many ways, this is the calmest part of the forecast.

After spending much of the second half of May talking about thunderstorms, flooding concerns, humidity, and rainfall totals, today's forecast almost feels strange. Not because anything exciting is happening, but because almost nothing is happening at all. Across Southern Middle Tennessee this afternoon, temperatures have climbed into the upper 70s and lower 80s under a mix of sunshine and fair-weather clouds. A refreshing northeast breeze continues to move through the region, and for the first time in quite awhile, radar across much of Tennessee is remarkably quiet.

If you spent part of your morning watching radar, you're probably not alone. A line of thunderstorms pushed through Southern Middle Tennessee during the late morning hours, bringing pockets of heavy rain, gusty winds, and plenty of lightning before sliding south into northern Alabama. While a few isolated storms may still try to redevelop this afternoon, especially west of Interstate 65, the overall trend is becoming increasingly clear.

After what has felt like an endless stretch of clouds, humidity, and scattered thunderstorms, Southern Middle Tennessee is finally beginning to see hints of a pattern change. Now before everyone gets too excited, we still have an active weekend ahead of us. Showers and thunderstorms remain likely at times through Monday, and some locations will pick up additional beneficial rainfall.

If the radar has felt chaotic lately, there’s actually a reason for that.

Southern Middle Tennessee is beginning to transition away from the classic spring severe weather pattern and into a much more summer-like setup. That means thunderstorms are becoming less organized, more localized, and MUCH harder to forecast perfectly from town to town.

After what feels like an eternity of clouds, muggy air, and nearly daily showers and thunderstorms, Southern Middle Tennessee may finally be getting closer to a legitimate pattern change. Now… before anybody gets TOO excited, we still have several more days of scattered rain and storm chances ahead of us through the weekend. But for the first time in awhile, forecast guidance is beginning to show a more meaningful shift in the overall atmospheric pattern across the eastern United States.

If it feels like Southern Middle Tennessee has been stuck in an endless cycle of clouds, humidity, and popup downpours lately… you’re not imagining things. After one of the driest starts to spring we’ve seen in awhile, the weather pattern has COMPLETELY flipped over the last couple of weeks. Instead of fighting drought and dry cold fronts, we’re now dealing with a tropical-feeling atmosphere capable of producing repeated rounds of showers and thunderstorms almost daily.

If you’ve got outdoor plans for Memorial Day weekend across Southern Middle Tennessee, the forecast is honestly a little frustrating… but it’s also not a complete disaster. This does NOT look like a nonstop, all-day rain event from now through Monday. At the same time, it’s definitely one of those weekends where you’ll want to keep the radar nearby, have backup indoor plans available, and expect periods of showers and thunderstorms each day.

Southern Middle Tennessee remains locked into a humid, unsettled late-May weather pattern, but Friday may feature a slightly more organized round of thunderstorms compared to what we’ve dealt with over the past several days. Most of this week’s activity has been dominated by slow-moving, tropical-style showers and thunderstorms producing torrential rainfall, lightning, and occasional gusty winds with very little organization. Friday, however, may briefly allow a few stronger storms to develop as winds increase aloft and another upper-level disturbance moves through the Tennessee Valley.

If you’ve been waiting for rain, Southern Middle Tennessee is finally entering the kind of weather pattern that can deliver it… and honestly, it may stick around through the end of May. After weeks of drought, stubborn ridging, and storm systems repeatedly weakening before arriving here, the atmosphere has undergone a major pattern shift across the eastern half of the country. Instead of one quick cold front moving through and leaving, we’re now entering a prolonged stretch of humid southwest flow, stalled boundaries, and repeated disturbances moving across the Tennessee Valley.

After weeks of talking about drought, dry lawns, and rain constantly missing Southern Middle Tennessee… the atmosphere is finally shifting into a much wetter pattern. And honestly, some locations may end up seeing TOO much rain over the next several days.

This week’s rain also raises a bigger question that a lot of people have been asking lately:

Why has it been so dry this spring?

The answer is actually pretty fascinating… and it goes much deeper than simply “bad luck.”

We’re running a little late on today’s blog, but honestly… the weather pattern hasn’t changed much since this morning. Southern Middle Tennessee is heading into a full-blown summer preview weekend with temperatures climbing well above normal, very little rainfall, and drought concerns continuing to worsen across the region. The good news? It finally looks like the atmosphere may at least attempt to bring better rain chances back into the picture by the middle portion of next week.
