South Mississippi Forecast 6/29/21

The rainy-ish pattern continues as the very humid airmass continues to hang around. And while things aren’;t quite as humid this morning as they were yesterday, it is still more humid than average. Much more.

South Mississippi is sitting about 110-percent of normal. That is a lot better than where we were 24- to 36-hours ago. And more relief is on the way, it just won’t likely make it all the way to South Mississippi.

You can see on the graphic above that the purple (very humid) air is knocked back across northern Mississippi and Alabama eventually. But for the rest of the region, no dice.

And while the humid air is in place, the chance for afternoon storms will continue. And those afternoon storms will be able to drop even more rainfall, too.

For those asking, “What gives?! Why is it so rainy?” The area is stuck in a humid pattern where some pretty juicy air has been funneled up from deeper in the tropics. And historically, this more-humid-than-normal-air would be mixed out with drier air aloft as there was daytime heating or afternoon convection.

But right now, even the air aloft is humid. So there is no help.

One thought on “South Mississippi Forecast 6/29/21

  1. Why say there is relief on the way and then say it won’t make it all the way ‘here’? Why call it relief if it’s not coming?
    ‘Why is it so rainy’, you ask? My response is ‘When has it NOT been so rainy’?
