Meteorologist Mark’s Wx Concerns

The Storm Prediction Center has placed our region in the marginal risk for severe storms for Monday. This is for the threat of damaging wind gusts that any storm could produce. Storms could also produce heavy rainfall that could drop visibility quickly, deadly cloud-to-ground lightning, and even small hail.

Almanac for Yesterday


Tropical Storm Claudette has weakened to a tropical depression and is moving through Georgia. That system will move back over ocean waters tomorrow and likely regenerate into a tropical storm once again. It will continue to be called Claudette. It’s not that unusual for systems to redevelop after crossing land, as they race away from the U.S. in Atlantic waters.

Sun & The Moon

Summer Solstice happens tonight! I’ll have a special blog post later on this evening about this.

NASA Nerdology 

Tonight marks the summer solstice. That means the northern hemisphere is tilted toward the sun more than any other day of the year. That also means we get more daylight hours than any other day of the year. Here on the plateau, that means 14 hours, 36 minutes, and eight seconds worth! After today, daylight hours start getting shorter. Tomorrow’s daylight, for instance, drops by one second to 14 hours, 36 minutes, and seven seconds.

Sunday Story


On the morning of June 10th, many folks in the eastern U.S. were treated to a sunrise solar eclipse. What a treat that was!

For our area, we could have seen the sun covered by about 10%, but clouds obscured our view. It always amazes me how something thousands of years in the making can be obscured by a few low clouds passing by. 

Eclipses at sunrise or sunset create stunning pictures of a sun low on the horizon, with what appears to be a “pac-man” looking bite out of it. 

A solar eclipse is what we had on the plateau back in August of 2017. The Moon comes between the Earth and the Sun, causing part of the sun to be blocked by the Moon. In order to get the full effect of the eclipse, you must be where there is 100% totality; not even 99% will do. 

Even though the Moon is 400 times smaller than the sun, the close proximity of it to Earth makes it seem about the same size as the sun in our sky. 

If a total eclipse occurs during the day, it can cause temperatures to drop.Oftentimes, a cool breeze even develops, due to the temperature differences between nearby areas that are not completely shaded, keeping them warmer than areas within the total eclipse. 

The next total eclipse occurs in April 2024 from the southern plains to New England. It will occur during the peak of severe weather season. One can’t help but wonder what effect an eclipse would have on a severe weather situation? Would storms suddenly weaken, or would they suddenly strengthen? Perhaps we’ll find out!

In the past, people feared eclipses because they didn’t understand them. Today, science has made us less afraid of an eclipse, allowing us to enjoy the bizarre treat from nature.
