Baldwin’s Wednesday Wx Blog for May 20

Wx Blog Slides - 2020-05-20T080050.285

Weather Headlines

An unsettled/summer-like weather pattern continues to evolve.

Main threats

No widespread hazardous weather is expected. However, as we saw yesterday, any storm that develops can put down some very heavy rainfall. Some parts of the plateau have picked up over four inches of rain in the past 48 hours. The Weather Prediction Center has included the plateau in the marginal risk for flooding for today (not marginal risk for severe storms). As you can see, that risk for flooding is greatest over in the Carolinas, where a very dangerous weather scenario is unfolding this week with flooding.

Like I said, the plateau is in the marginal risk for flooding today.

Baldwin’s Severe Wx Concern

My only concern is with localized flash flooding from slow moving heavy showers/storms. Just be careful if you’re out driving and get caught in one of those downpours.

Tropics

All is quiet. I will suspend this section after today unless something else develops. Beginning June 1st, this section will appear here regularly and will continue to do so through November. Hurricane season runs from June 1 to November 30.

Records

On this day in 1894 a snow storm blanketed central and eastern Kentucky with several inches of snow! Lexington measured half a foot of snow. Other snowfall totals ranged from two to eight inches.

If you want to see a tornado you might consider moving to Codell, Kansas. They were hit in three consecutive years by a tornado on May 20 (1916, 1917, and 1918). I don’t know about you, but I would have had my eyes to the skies on May 20, 1919!

NASA News

I’ve decided to heed the advice of some very smart people and not attend the rocket launch next week. However, I have decided to make next week LAUNCH WEEK! I’ll do something cool each day next week, starting with Sunday. Make sure to tune in and tell all the space nerds in your life to tune in, as well. It should be fun!

Pictured below is the DEMO-1 launch I was so incredibly lucky to attend last March. This was the uncrewed version of next weeks crewed DEMO-2 mission. What a launch this was and what an unforgettable experience!

Baldwin’s View-of-the-Day

Yesterday, at least two dams failed in eastern Michigan. The result has been a disastrous flooding event. Let’s keep those folks close to our hearts today.

Weather News

I hope to get the MASTER science class for kids started up by the end of summer. It just depends on when Roane State is comfortable with that, as well as the State’s guidelines. Stay tuned. I’ll let you all know just as soon as we can get those going again!

Answer to Trivia Question

A: (d) Oklahoma City is in a class by itself when it comes to tornadoes. That city has been hit at least 140 times by tornadoes since records began in the 1890s!

You all have a great day!

  1. When you looked at the heaviest rainfall, did you look at Hurricane Harvey? Living in the Houston area at that time I remembered NOAA reported 6+” of rain per hour during that long day/night with final reports of 60+ inches. It was horrific.

    That event was the impetus for us moving to the Plateau.

    We enjoy your reports very much. They are so much more accurate than the television types.

    Respectfully Terry

    1. Good evening, Terry. First of all, I’m so glad you enjoy the blog! I always appreciate hearing from folks who enjoy what I do. I also want to welcome you to the plateau, though I’m sorry such a historic natural disaster is what caused you to move here. Harvey was, by far, the most prolific rain producing storm in US history. It’s still hard to believe that FEET of rain fell. That’s unimaginable. The confusing part is how much of that fell in 24 hours. Few people doubt that Texas broke 24 hour rainfall records in some locations, but whether or not those locations are “official” measuring locations is where things get confusing. Harvey remains the highest producing rain event in the continental US and I think that record will stand for many, many years to come. I sure hope no one else breaks that record!
