Bundle up on your way out!

For those of us getting off work at 4:00, be ready to bundle up! The current air temperature is now only 18 degrees. A north wind at 7 mph makes it feel more like 6 degrees.

Snow flurries will taper off as go through the evening. As skies clear tonight the temperature will drop to around 10 degrees.

Hopefully skies will clear in time for the 6:00 rising of the Full moon. For those of you who like to get some good moon pictures, tonight should be a good night for it. Just don’t freeze to death. ha

You all stay safe and warm!

Going out for lunch? Check that temp first!

If you must go out for lunch just keep in mind that our air temperature is now 21 degrees at 11:30, with a north wind at 11 mph. This creates a feel-like temp of 10 degrees. That temp will hold steady or slightly fall the rest of the day.

Our record low for tonight is 18 degrees. That will be shattered, as will numerous other records across the country tonight. Many of those records have stood for over 100 years.

Are we sure it’s not January 12th, instead of November 12th? ha

With temps this cold tonight, make sure your neighbors (esp the elderly and at-risk) are ready for this cold. It never hurts to just drop in and say hello and make sure their heat is up to speed.

And don’t forget those outside furbabies! They get hypothermia, too. If you can’t bring them inside, get them some straw, warm blankets, etc.

Snow flurries should continue through the afternoon for many of us, with clearing skies coming tonight.

Some cool looking satellite imagery

Folks to our northwest picked up more snow than we did. Whenever there is snow on the ground, visible satellite imagery can “see” it. While snow and clouds are both white, the snow doesn’t move and the clouds do. That allows you to notice the difference between the two.

In the satellite imagery below, notice how cool-looking the rivers and streams are against the snow. They really shine out!

Notice the lake-effect snow falling southeast of the Great Lakes. Northwest winds are really cranking up that lake-effect machine today.

You can also see how northwest winds cause the air to rise on the western slopes of the plateau. That rising motion forces clouds to form and/or linger over us for much longer than they do anywhere else. As that air than moves over the plateau, it has to sink back into the valley of East Tennessee. That shows up a little bit in this imagery over the Knoxville area, where there appears to be a line running up the valley that may have more sunshine.

That sinking air really shows up well in western North Carolina. Like on the plateau, the winds rise up the western side, move over the mountains, then sink back down on the other side. Rising motion leads to clouds, sinking motion leads to clearer skies.

Notice the snow across northern Missouri, Iowa, western Kentucky, Illinois and Indiana. Meanwhile, clouds hang on for dear life around here and will likely do so through most of the afternoon. Clouds love our plateau! (ha)

I should point out how the north winds at the surface are blowing through Alabama, while the winds aloft are clearly blowing those clouds on southwest winds. As we get later into the season, we’ll have to watch such scenarios very closely for our area. That would be a classic scenario for a winter storm for us, with cold air at the surface moving out of the north, while moist air moves out of the southwest overhead.

The tricky part is getting those two to align. Then, you have to figure out if the cold air is “deep” enough for snow or shallow enough for freezing rain. It’s enough give ya a headache! ha

I hope you’ve learned some meteorology and that you are just as anxious as I am to see what this winter holds! One thing is for sure, you can get ANYTHING around here in the winter. We can get bad storms, big floods, winter storms, freezing cold…you name it! That’s what makes winter in this part of the country so interesting and what makes it my favorite season of the year!

Plus, there’s Christmas. I mean, come on, does it get better?
