Quick Special Summary

This morning’s storms are making a lot of noise. That is pretty typical for warm fronts. They really make the atmosphere a turbulent place, with lots of rising motion. Warm air is trying to move in but it’s having to ride up and over the cooler morning air in place. Warm air is light and easily glides up and over the cooler surface air. That leads to a lot of turbulence above. That also makes for hail chances and that’s why we’ve seen some warnings around Fentress County this morning. One inch hail is the main threat. The rest of us can expect strong, possibly severe, storms with this morning round of storm activity.

Meteorologist Mark’s 5-Day Wx Concerns

Meteorologist Mark’s Wx Discussion

Today’s set-up, like most this spring, is complicated. This morning’s storms may help stabilize the atmosphere for later storms, but I’m not quite sure about that working out. Some models show some very severe storms later this afternoon but most of them stay across southern Middle TN. I’ll keep an eye on that. Later tonight, a line of strong to severe storms will move through and that will pose another threat. I’ll track the evolution of that through today. With it coming in the very early hours of Sunday that could help us out. The atmosphere is often more stable at that time of day.

I’ll be tracking it all today!

NASA Nerdology 

In 2007, astronaut Sunita Williams became the first person to run a marathon in space after she registered for the Boston Marathon and finished the 26.2 miles in about 4 hours and 24 minutes on the International Space Station treadmill! How cool is that? IF I ever get to go I’m definitely going to do this!

You all have a great day and keep lookin’ up!
