A very active pattern!

Wintry mix Wednesday night/Thursday morning?

Meteorologist Mark’s Wx Vlog 

48-Hour WX

Seven-Day Forecast

Daily Forecast Summary

Today: Mostly cloudy. Flurries develop overnight, w/ no accumulation expected at this time.

Tuesday: Partly to mostly cloudy. A chance for a sprinkle or flurry.

Wednesday: Increasing clouds. A light wintry mix possible overnight.

Thursday: Possible morning wintry mix, followed by rain showers as temps warm.

Friday: Chance of morning showers. Otherwise, partly to mostly cloudy.

Saturday: Partly cloudy.

Sunday: Showers likely.

Meteorologist Mark’s Wx Concerns

Overnight lows Wednesday will fall below freezing, just as a new storm system is moving in from the south. There is a chance, albeit small, that the rain will arrive before temps are able to climb above freezing. If that should happen, there could be a glaze of ice around the area late Wednesday night and possibly into Thursday morning. Confidence is low on this occurring but stay tuned for any updates. This would likely not be a snow situation, as warm air aloft would likely lead to this being a light freezing rain event. Any ice that does occur would be light and short-lived, as warm air will win out by the mid morning hours of Wednesday, at the latest.

Meteorologist Mark’s Wx Discussion

I’ve created four different seven-day outlooks this morning (ha). The struggle is real when it comes to winter weather forecasting for the plateau! First of all, we have another disturbance coming through tonight. That could lead to another round of snow flurries. At this time, I don’t even see us getting a dusting from this one. I’ll keep an eye on it though. If it can tap into a bit more moisture I’ll make a special blog post this evening to update you.

The greater concern, and it is of low confidence, is the small chance for a light wintry mix Wednesday night into Thursday morning. This is one of those situations where little to nothing is likely to happen, but since it’s an ice potential, we all know it only takes a spit of ice to make for a travel problem. I’ll keep a close eye on this. The most we would get would be a glaze of ice from the rain beginning as a wintry mix. Again, I’ll keep an eye on this and let you know if anything changes.

As precip ends Thursday night, we could see another round of wintry weather but my confidence is so low on that happening that I didn’t mention it in the forecast above. After that, the forecast begins to focus on a rain-maker coming Sunday.

This is a very active pattern and that means there is the potential for quickly changing forecasts. Be sure and stay tuned!

On This Day in Wx History

1994- A record cold air mass pushes into the mid state. The high temperature reaches just 10 degrees at Nashville. The plateau is especially hard-hit, as Crossville checks in with a low of -8.


Yesterday’s National Temperature Extremes

High: 91° at Camarillo, Beverly Hills, and Pala California 

Low: ° (data unavailable today)

Today’s National Wx Hazards

Snow flakes are flying from the Ohio Valley to New England today. More snow can be found from the Four Corners region to the northern plains.

Tomorrow’s National Wx Hazards

Snow flakes will fly from New England to the northern plains. Another area of snow will be found right on the Four Corners region of the Southwest.

 Weather Shots

I awoke to another dusting of snow this morning! I’m getting used to this (ha). And, like a typical Tennessee snow, it’s already melting and about gone by mid-morning.

NASA Nerdology

On Saturday, we conducted a hot fire test of the core stage for the @NASA_SLS rocket that will launch @NASAArtemis missions to the Moon. Find out more about the test: NASA expects this rocket to be ready to slingshot us around the Moon by the end of this year!

A lot of folks say this all feels like Deja Vu. We’ve already been to the Moon, so why go back? Truth is…that was a long time ago and technology has improved by leaps and bounds. We want to go back safer and faster this time. Plus, we need to perfect going to the Moon, so that we can go to Mars more safely and efficiently. Let’s just hope the Biden administration is as generous to NASA as the Trump administration was……….

You all have a great day!
