We have seen our share of tornadoes this year in Middle Tennessee and Southern Kentucky. There were 10 tornadoes in February and March.
Nine came on February 24, including the damaging twisters in Clarksville and Hopkinsville, and the tornado that killed a woman in Logan County, Kentucky. On March 19, there was one more in Franklin County near Decherd, Tenn.
But historically, the worst month for tornadoes in our region is actually April, followed by May. So it’s no surprise that News 2 meteorologists and the National Weather Service are preparing for the threat of severe weather on Tuesday.
News 2 Meteorologist Davis Nolan paid a visit to the NWS office in Old Hickory, where Krissy Hurley, the Warning Coordination Meteorologist, took a deep dive into the powerful NEXRAD Doppler radar.
She explained what they look for and how she sends out a tornado warning.
“First, you can see the green and red signature, with the greens meaning winds going towards the radar, and the reds going away from the radar,” said Hurley.
“This is an example of one of the tornadoes in Montgomery County on February 24th. Once we get the movement established on the radar it draws this polygon, where I’m going to hit the tornado warning for a time frame. I’m going to go 45 minutes. Because we had not had confirmation that it was on the ground, I am going to choose Doppler Radar Indicated.”
Even when there’s no tornado, straight line winds can be damaging. That’s the biggest threat for Tuesday, especially in the west and northwest counties of the mid-state.
