Meteorologist Mark’s Wx Thoughts (New!)

Additional data today should offer more clues as to what we can expect Thursday. Right now, I wouldn’t be surprised to see a wintry mix for all this precip event, even for the precip that falls during the day (wet snowflakes & sleet mixed in the rain). However, surface temps should stay above freezing, preventing any problems. By evening, colder air will arrive but the moisture will be quickly departing. It just depends on how much moisture lingers as to how much, if any, snow we get (typical set-up for our area). Models are consistently painting more snow south of I-40 but that could certainly change.

Another round of light snow could arrive Sunday night and/or Monday. We’re just too far out to say much about that. This will be from a low that tracks across the Southeast, drawing in some Gulf moisture. It’s worth keeping a close eye on.

Wx Threats for the Next 7 Days

Light snow may produce some light accumulations of snowfall across the plateau Thursday night. At this time, the greater chance for that snowfall may be found south of I-40. I’ll keep a close eye on this and keep you posted!

Another chance for light snow may come Monday, but it is far too early to say much about that just yet. Stay tuned.

Meteorologist Mark’s Snow Scale

Confidence remains low, due to the uncertainty in how much precipitation will be left over when the colder air arrives. At this point, areas south of I-40 look to have the better chance for any accumulating snowfall.

On This Day in Wx History

1960- A winter storm brings heavy snowfall to much of Middle Tennessee. Crossville measures 8″ of snow, while Tullahoma reports 7.9″, and Nashville, 7.3″.

Today’s National Wx Hazards

Areas of mixtry wintry precip, including areas of freezing rain, will impact the northern plains today. Accumulating snowfall can be expected in the colder air of the Front Range of the Rockies. Even more snowfall can be found in the mountains of the Pacific Northwest.

Tomorrow’s National Wx Hazards

Accumulating snowfall may fall in the mountains of West Virginia, as well as across parts of the northern plains/Upper Midwest. Even more snow is expected across Idaho and western Montana.

 Weather Shots

It’s not every day that you see a tornado in California, but that’s just what happened yesterday, as you can see for yourself! This great photo was taken by Derrick Baker in Tehama County, California.

NASA Nerdology 

During this week in 1959, a Soviet spacecraft, Luna 1, made its closest approach with the Moon at 3,976 miles away. Luna 1 was the first human-made object to escape Earth’s gravity.

You all have a great day!
