Meteorologist Mark’s Wx Concerns

Any wintry mix that occurs tonight will likely happen while many of us are sleeping. However, just in case anyone may be out and about in the wee hours of the day Thursday I wanted you to be aware that there could be some slick spots when that rain first starts to fall. Temps are expected to quickly rise after midnight and should be above freezing by sunrise, just as many of us are headed to work and school.

Meteorologist Mark’s Wx Discussion

Thankfully, that narrow window of opportunity for tonight’s wintry mix is looking more and more narrow. The wintry mix is also looking very light and will probably not cause any troubles. Never the less, if you must be out late tonight or before sunrise Thursday, be careful.

Another powerful storm system is poised to move in Sunday night. This system could bring heavy rainfall and even some thunderstorms. At this time, severe weather is looking unlikely. We could use the rain, as we are now over two inches below normal on rainfall for the month. Keep in mind that while we’ve had several little snows, that snow has very little moisture content. A snowflake is about 90% air!

 Weather Shots

I saw the most dramatic sundog in the sky yesterday evening that I’ve ever seen. I grabbed the camera, of course! (ha) A sundog results from the sun’s light reflecting off ice crystals high in the atmosphere, typically from Cirrus clouds. The sundog looks like a little rainbow, 22 degrees out from the sun. It’s like a ring around the Moon at night, which also forms a 22-degree arc.

NASA Nerdology 

With a new presidential administration comes an end to the tenure of NASA Administrator Jim Bridenstine. Let’s sincerely hope that the Biden administration does not follow the dismal path of the Obama administration, who had little interest in NASA and their incredible mission.

NASA writes, “The failures of past efforts mean that Bridenstine, born in 1975, is the first NASA administrator not to have been alive when people last walked on the moon. “I think it’s important that I be the last NASA administrator in history that wasn’t alive when we had people living and working on the moon,” he said. “That’s a failure of the United States and of humanity. We need to make sure that we’re leading the world in a return to the moon and on to Mars.””

You all have a great day!
