Main Threats

Today: Seeing the sun may come as a shock to you. Please be aware of this coming attraction.

Summary

The sun will shine today. I know it’s hard to believe but it is coming! But first, how about that fog this morning? Our dense fog advisory goes to 9:00 a.m. but it may need to be extended.

We’ll remain dry through at least Sunday. There may be an isolated shower today but I wouldn’t count on it. The chance of that is about 10%.

Our next chance of showers may arrive Monday evening, but I’m not sure enough of that to add it to the five-day outlook above. Rain chances Tuesday look much more promising at this point.

So far this year we’ve received 53.10 inches of rain here at weatherTAP in downtown Crossville. The average yearly rainfall is 56 inches. Yeah, it’s been a wet year!

Below is the rainfall we have received since Friday, according to the NWS Nashville.

Tropics

Things are looking quieter in the tropics. We’ve been monitoring Kirk in the eastern Caribbean but it now looks like he will dissipate. The environment down there is very hostile and he will likely be torn apart. I think we can nail the coffin shut on him after today.

Leslie’s remnants continue to spin out over the open Atlantic, but that is absolutely no concern to the U.S. mainland.

Hurricane Rosa is over in the eastern Pacific and that will be moving into the southwestern U.S. this weekend, bringing some needed rainfall there.

News

The NWS Nashville has confirmed that an EF-1 tornado struck just west of Clarkrange at 11:52 p.m. Tuesday night. The tornado was brief and rather weak but caused damage to a residence on Campground Road. An outbuilding was shifted off its foundation and a barn sustained significant roof damage. Three windows were also blown out of a residential building. The tornado was estimated to have had winds of 90 mph. The tornado was on the ground for half a mile and was 50 yards wide.

There was no warning for the storm and it showed no significant signature on radar. Like I said yesterday, the radar beam is at about 5,000 feet up by the time it reaches the plateau, which can cause the NWS to miss some weaker, short-lived tornadoes.

This storm reminds me, as it should you, that the fall season is our secondary peak in tornado activity. This peak isn’t nearly as pronounced as the one in the spring, but it’s worth noting none the less. I wrote an article that was published in the Fentress Courier and Livingston Enterprise last week about this severe weather season that folks tend to forget about. I hope you enjoy it and maybe even learn something from it.

You all have a great Friday and a nice weekend!

The Fall Severe Weather Season

With the coming of fall, thoughts turn to changing leaves and cool, crisp days. But, for those of us in the weather business our thoughts turn to the fall severe weather season.

Most people are familiar with severe weather in the spring. The change from colder weather to warmer weather is often a collision of air masses that leads to storms. Sometimes, these storms send us running to the hallway or basement.

Many folks tend to forget that we have a secondary severe weather season in the fall. This secondary peak in severe weather activity is not as active as the spring one, but it is worth noting.

This slight, secondary peak in severe weather in the fall is similar in origin to the one in the spring. It results from the seasons changing, with summer losing its stronghold as winter begins to move in.

We have had some notable severe weather outbreaks on the plateau in the fall. On the tenth day of November of 2002 Cumberland County had the most violent tornado in their county’s history. The EF-3 claimed four lives and cut a swath of devastation that stretched for 12 miles. This tornado was part of the worst November tornado outbreak to ever strike Middle Tennessee.

Other notable fall tornadoes for our area include an F-2 In 1957 that tracked for nearly 14 miles along the eastern edge of Fentress County. The storm caused 25 thousand dollars in property damage. Tornadoes in the fall of 1973 and 1977 caused a total of $275,000 worth of damages in Overton County, proving that fall tornadoes can be quite destructive.

So, even though storms are likely far from your mind when you think of our beautiful autumn season, you mustn’t ignore those dark storm clouds, should they start to gather.
