Wx Hazards Across the Nation

Strong to severe storms are likely today across two areas of the country. The first is across much of Oklahoma and the Texas Panhandle. The second is along the coast of the Northeast. North of that threat area will be light wintry precipitation. Elsewhere across the country, only light precip is expected, whether that be liquid or frozen.

Records

A tornado outbreak on this day in 1967 produced 48 tornadoes across the Midwest. Hardest hit was northern Illinois, where 16 of those tornadoes touched down. The town of  Belvidere, along with the Chicago suburb of Oak Lawn, were heavily damaged. Fifty-seven lives were lost that afternoon, mostly in Belvidere and Oak Lawn.

Weather Trivia 

Q: Tornadoes usually form in what part of the storm?

a. the front   b. the middle   c. the rear

(Answer at the bottom of the blog!)

NASA Knowledge

The Lyrid Meteor Shower will be visible tonight! It actually peaks in the morning, but you should see some at any point in the night.

We have two things going for us….there’s no moon to flood the sky with light AND skies will be clear. The only downside is that there aren’t very many of these shooting stars.

“This will actually be a good year for the Lyrids and it is exciting the peak is on Earth Day and in the middle of International Dark Sky Week,” said Bill Cooke, lead of NASA’s Meteoroid Environment Office at NASA’s Marshall Space Flight Center. “While the Lyrids aren’t as prolific as other meteor showers like the Perseids or Geminids, they usually do produce some bright fireballs, and since the Moon will be nearly invisible April 22, rates should be about as good as it gets for this shower.”

Up to 15 meteors per hour are possible.

The meteor shower will stem from the constellation Lyra, thus the name Lyrids.

So, go out and have a look! I’ll send out a reminder, with even more info, later on this evening!

Answer to Trivia Question

A: (c) The rear. Most tornadoes form beneath the mesoscyclone, which is the lowering and rotating base near the rear of the storm.

In the image below, the storm is moving to the right, with the tornado at the rear.
