Meteorologist Mark’s 5-Day Wx Concerns

It’s not often that I highlight a threat this many days out, but this seems worth mentioning. The Storm Prediction Center has highlighted all of Middle TN in a threat for Wednesday. There are strong indications that this could be a significant severe weather threat for the South, I’m just not sure exactly how much of that will affect our region. I’ll keep you posted. This will give you a chance to monitor how the risk changes from now until then.

This is the outlook from the Storm Prediction Center for Wednesday. Notice the risk comes right up to the plateau. Definitely something for me to keep an eye on. This could also mean it gets here during the night, after affecting areas to our west during the day. Keep that in mind.

Meteorologist Mark’s Wx Discussion

The rain and storms for Monday look to be rather benign for our region, though some of that rainfall could certainly be heavy. We’re behind on rainfall these days, so I don’t think flooding will be an issue.

The main concern in this forecast period is Wednesday. If you have plans on Wednesday, keep in mind that we may be facing the threat of severe storms. You really need to keep this in mind if you plan on being in Nashville that day. The threat may hold off until dark, but it’s far too early to tell those specific details just yet. It’s just something to monitor for now and to make you aware of.

If you don’t already have a weather radio, you need to get one. They sure can come in handy, especially for overnight event. We see these things save lives every year. I highly recommend this one and I advise you get one today at https://amzn.to/3qH6y6T. I’ll even help ya get it set up! My goal is to make this plateau the most storm-ready place in the country! Let’s stay safe in the spring storms to come.

On This Day in Wx History

1993- The Storm of the Century (aka Blizzard of ’93) brings heavy snow to the Cumberland Plateau. Jamestown receives the highest storm total snowfall ever measured in Middle Tennessee, with a whopping 26″ of snow. Crossville sets a station record with a storm total of 20.5″ of snow, while Allardt sets its own one-day snowfall record with 14.1″.

Yesterday’s National Temperature Extremes

High: 100° at Rio Grande Village, Texas 

Low: -19° at Daniel, Wyoming

Today’s National Wx Hazards

Strong to severe storms will affect areas from the Texas and Oklahoma Panhandles and western Texas today. Long-track tornadoes are possible there. Flooding rainfall will threaten parts of Kansas and Nebraska, while the heavy rain turns to heavy snow in the colder air of the Rockies and Front Range. A wildfire danger will exist from eastern New Mexico to extreme western Texas.

Tomorrow’s National Wx Hazards

The severe threat shrinks as it moves east, affecting mainly the Mississippi/Arkansas Mississippi Delta region. Farther north, the precip turns to an ice threat across southern Minnesota, eastern Iowa, and northern Illinois. Heavy snow will fall across the Front Range of the Rockies and also across the mountains of northern California. More snow is expected across New England. Finally, a wildfire danger will once again be present across portions of western Texas.

 Weather Shots

On this day in 1993, the most powerful non-tropical storm ever recorded in the Gulf of Mexico roared ashore and unleashed a blizzard of historic proportions on the eastern United State. This is satellite imagery from that day.
