Weather Headlines

A slightly better chance for some stronger storms Friday afternoon

Unsettled weather continues, with more rain and storm chances

Main threats

The Storm Prediction Center has placed much of the plateau in the MARGINAL RISK for severe storms for Friday. The main threat is an isolated storm with a severe wind gust. We basically have this threat every day with afternoon/evening storms, but the threat is slightly higher tomorrow. The main threat will continue to be heavy downpours of rain that could lead to localized flash flooding.

Baldwin’s Severe Wx Concern

Wx Blog Slides - 2020-05-21T082723.780

I’m still keeping my concern on the lowest end of the scale. Still, any storm that develops in the heat of the afternoons/evenings will always be capable of an isolated severe wind gust and cloud-to-ground lightning. Be aware of this if you plan to be outside a lot this Memorial Day weekend. Enjoy your outdoor plans, but always keep an eye on the sky and a glance or two at the radar. AND…if you hear thunder you are close enough to be struck by lightning, even if the sun is shining where you are.

Baldwin’s 7-Day forecast

Wx Blog Slides - 2020-05-21T082058.827

Daily Forecast

Today: Our best chance for widespread showers and storms this forecast period will be today. The upper-level low is beginning to slowly pull away and that will drop rain chances a bit in the coming days.

Friday: Rain chances drop a bit but that allows heat to build a bit more. That additional heat will add some fuel to the atmosphere and lead to the possibility of a strong storm in the afternoon. Just be aware of that.

Saturday – Memorial Day: Scattered showers and storms, especially in the afternoons.

Tuesday – Wednesday: Rain chances drop off a bit more, but they certainly don’t drop to zero.

A tornado outbreak across the Ohio Valley led to numerous cities being impacted by tornadoes on this day in 1860. Those cities include Louisville, KY, Cincinnati, OH, Chillicothe, OH, and Marietta, OH. Damages ran up to one million dollars. That was a LOT of money in 1860!

SpaceX Demo-2 Crew Arrival

NASA astronauts Robert Behnken, left, and Douglas Hurley speak to members of the media after arriving at the Launch and Landing Facility at NASA’s Kennedy Space Center ahead of SpaceX’s Demo-2 mission, Wednesday, May 20, 2020, in Florida.

NASA’s SpaceX Demo-2 mission is the first launch with astronauts of the SpaceX Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agency’s Commercial Crew Program. The flight test will serve as an end-to-end demonstration of SpaceX’s crew transportation system. Behnken and Hurley are scheduled to launch at 3:33 p.m. CDT on Wednesday, May 27, from Launch Complex 39A at the Kennedy Space Center. A new era of human spaceflight is set to begin as American astronauts once again launch on an American rocket from American soil to low-Earth orbit for the first time since the conclusion of the Space Shuttle Program in 2011.

I have walked on launch pad 39A several times and it is such an incredible experience to stand on that hallowed ground! I was also able to see the launch of DEMO-1 last March and it was one of the coolest launches I have ever seen. Godspeed to these guys as they set off on DEMO-2!

Baldwin’s View-of-the-Day

This is water vapor imagery from yesterday, showing our big upper-level low spinning right on top of us. That’s a pretty cool view, right? Watch those storms fire across the Southeast. Wow!

Answer to Trivia Question

A: (b) It’s a bit of a close call between Texas and Hawaii, but Hawaii wins this one. They picked up over four feet of rain (49.69 inches) in just 24 hours on April 14, 2018! In 1979, Tropical Storm Claudette dropped 42 inches of rain on Alvin, Texas.

Notice that was a tropical storm and not a hurricane. You don’t have to have a hurricane to have phenomenal flooding, and flooding is the number one killer and cause of damage in tropical systems. Funny that we only rate them on wind, right?

You all have a great day!
