MM’s Hourly Forecast

5-Day Forecast

MM says: Today is a MM Weather Alert Day. Let’s be weather aware and stay safe in any storm that may become severe. Better weather is coming Tuesday and Wednesday!

6-10 Day Temp & Precip Outlook

MM says…Well above normal temps are beginning to show up in the extended outlooks. Those outlooks also favor normal precip. Normal highs and lows this time of year are 81°/62°.

MM’s Weather Worries

MM’s Wx Analysis

A very active frontal boundary (unusually active for June standards) will continue to press southward today. As it does so, it will encourage showers and t-storms to develop. Some storms could be severe and some of the rainfall could be very heavy. This system will slowly push on through the area tonight, giving us nicer weather for Tuesday and Wednesday.

The vorticity (spin of the air) that I talked about last night did increase with the latest data. However, it increased much more to our west than it did here. This is one reason why the tornado threat is higher to our west today.

And StormNet is picking up on that, as well. The tornado threat is greatest across southern Middle TN, decreasing as we move toward the plataeau. Still, a spin-up can’t be ruled out for anyone on the plateau this afternoon and evening.

Radar-Estimated Precip from Yesterday

MM says….There were numerous severe storms in Illinios and Indiana on Sunday. You can see the paths of some of the strongest storms in southern Illinois and southern Indiana based on the rainfall they produced, as shown on the map below. You can even see where upper-level steering winds pushed storms in southern Indiana in slightly different directions (so much splitting of winds aloft, which helps severe storms). I’ve marked those storms with yellow arrows. The more northern storms went northeastward, the one south of it cut more eastward, and the ones farthest south went southeastward. You can literally see the split-flow, diverging flow aloft that steered the severe storms. That diverging flow aloft allows storms to grow and strengthen, creating healthy updrafts that can “breathe” and intensify. Pretty cool, right?

Issued June 21, 2026

Monday will be a Meteorologist Mark Weather Alert Day for the risk for severe storms.

Local matters, especially when it comes to your weather forecast! Bringing you your local weather since 2017!

MM’s Forecast Update for the Plateau

The radar has been very active today to our northwest. The energy for those storms has spared us any storms today. That activity is associated with a storm system that will push our way over the next 24 hours, bringing an increased risk for rain and storms. Some of the activity you see on this evening’s radar (seen below) will push our way overnight. It will weaken as it does so. This should give us some showers in the morning, but we should steer clear of any severe storm threats. I will continue to monitor that closely.

Breaking down the hourly forecast for tomorrow, I highlighted in orange the hours of greatest concern for any severe storms. As you can see, rain chances remain elevated all day. If morning showers and clouds hang around, instability will be more limited in the afternoon, which will reduce our severe storm threat.

I have increased our tornado threat once again. It’s still low, but not zero. Data suggests that there could be enough shear to give us a spin-up with a stronger storm. Damaging straight-line winds and localized flash flooding remain the greatest threat with any stronger storm.

MM’s Analysis…for those who want to know a bit more.

The weather map for Monday afternoon shows an area of low pressure centered over the Ohio Valley with a cold front extended southwestward from that low. As that front runs into our warm and humid air from the Gulf, showers and storms will develop. That front will slowly move across the area. The front eventually stalls out across the Deep South by Tuesday afternoon.

The above map shows you what’s at the surface, but the atmosphere high above us matters just as much as surface features. If we go alllll the way up to 30,000 feet into the atmosphere tomorrow afternoon, we see a disturbance in that flow aloft (circled). Anytime you see lines bend on pressure charts, we generally call that a “disturbance”. These disturbances encourage the air to rise, which encourages storms to form.

Something new with today’s data is the increase, however subtle, in vorticity for Monday. Vorticity is a measure of how air spins as it rises to form storms. In Tennessee, we see just enough vorticity for it to be a bit more concerning that the spinning air ingested by updrafts Monday afternoon could lead to enough spinning for a tornado. We’ll monitor this with tonight and tomorrow morning’s data to see if this increases or decreases.

StormNet is a product that has been improving for severe weather forecasting. It takes several factors into consideration to highlight areas that might have a tornado risk. Tomorrow’s threat for our region shows up quite subtly, but it has trended up in today’s guidance. We’ll see what this looks like in the morning, as well. The blue dot indicates where the plateau is.

As always, I’ll have a full update in the morning. You all take care, have a pleasant evening, and keep it right here with Meteorologist Mark for all the latest on the weather of the Cumberland Plateau!

Bringing you your tailor-made local weather forecast since 2017!

MM’s Hourly Forecast

5-Day Forecast

MM says: Today has continued to trend drier! If you play outside today, make sure you stay hydrated and safe in the heat and humidity. I’ll be tracking storms that may threaten us overnight.

6-10 Day Temp & Precip Outlook

Extended outlooks are starting favor warmer temps and wetter conditions. Normal highs and lows this time of year here on the plateau are 81°/61°. Average precip for this time period would be about 1.25″.

MM’s Weather Worries

MM’s Wx Analysis

A storm system to our northwest will gather strength today and produce severe storms from the central U.S. to the Ohio Valley. High pressure will hold for us again today. Meanwhile, moisture from the south will be moving north. That moisture is leftover showers and storms from the frontal system that impacted us last week. The two systems should work together to give us a good chance for rain on Monday.

Bringing you your tailor-made local weather forecast since 2017!

MM’s Hourly Forecast

5-Day Forecast

MM says: We’ve got a beautiful Saturday, with low humidity and comfortable temps. Get outside for that game of golf, that hike, or even a day at the lake! Stormier weather begins moving in by later Sunday and especially on Monday.

6-10 Day Temp & Precip Outlook

The extended outlooks favor temps that are cooler than average and rainfall that is average. Normal highs and lows this time of year here on the plateau are 81°/61°. Average precip for this time period would be about 1.25″.

MM’s Wx Summary & Analysis

This afternoon’s weather map shows a warm front to our south. That front will lift north tonight and Sunday, bringing a chance for a shower or storm to the plateau Sunday afternoon. That area of low pressure you see in Colorado will move east tonight and help make this front even more intense to our northwest on Sunday, with the potential for some significant severe weather focused on Missouri and Illinois. That front moves closer to our region on Monday, bringing widespread showers and storms. Some of the storms could be severe and some of the rainfall could be heavy. I’ll keep an eye on things!
