Main threats

TODAY & TONIGHT: Strong to severe storms will threaten. Damaging, straight-line winds will be the main threat. Prepare for the possibility of some power outages. There is also potential for flash flooding, so be aware of that.

Storms in Kentucky this morning are weakening, as they slowly push southward. Some of these will hold together enough to effect the northern plateau, in particularly for Overton, Fentress, and Scott counties and points north. Some new development is noted on radar, likely from outflow boundaries, across northern Overton and Fentress counties at this hour. The main action for all of us will come later today with new development.

Below is a view from weatherTAP’s RadarLab National at 8:40 a.m., showing a large cluster of rain and weakening storms in Kentucky, with some new development along the northern plateau. Storms are moving to the east.


The Storm Prediction Center had placed us all in the 2% chance for tornadoes. That’s the lowest threat level on the scale. However, in the 8:00 update they removed that threat and it’s now back to being focused on damaging straight-line winds. Please keep in mind that straight-line winds can be as destructive as weak tornadoes, only the damage is in a relatively straight path.

After we get finished with today and tonight’s rain and storms, the rest of the week and weekend are looking good.


The Atlantic and Gulf basins are quiet for now, though some models are suggesting some Gulf development this weekend near the coast. It’s nothing the hurricane center is mentioning just yet, but it’s something to keep in mind.

Squall lines that take on a bow shaped appearance and become a widespread, long-lived wind storm are often called derechos (deh-REY-cho). The word derecho translates to “straight ahead” in Spanish. The winds associated with derechos can exceed 100 mph and do as much damage as a tornado. The only difference is that the damage from a derecho is all in a relatively straight path.

Below is a radar mosaic showing the progression of a derecho as it moved into our area on May 27, 2017. I circled Cumberland County for reference.



On this day in 1985 a horrific hailstorm struck Logan, Kansas. Winds up to 70 mph carried golf ball-sized hailstones. Some hail drifts were three feet deep and required road graders to clear it from the roads. The hail disintegrated crops, stripped trees of their leaves, and shattered windows all across the area.



One year ago today

The high was only 82 degrees, after a morning low of 60. That was a cool morning! No rain fell.


There are still some spots left in the 11-13 year old Big Sparks class that I will be teaching on September 5 at Roane State (Crossville campus). Sign up before the class fills!
