After a stunning day today with a high of 82, an approaching front will change things dramatically tomorrow. A 4WARN Weather Alert has been issued for tomorrow as the recipe is right for severe storms. This is the greatest potential we have had here in a while. The Storm Prediction Center has placed the western part of Middle Tennessee in a “Moderate” risk zone (4 on a 1-5 scale. The other half of the mid state is in an “Enhanced” risk zone (3 on a 1-5 scale) and a “Slight” risk zone (2 on a 1-5 scale).
This is a rare designation for us, I can remember only a few times the SPC has put us in a risk category this high. The greatest threat will be damaging wind and large hail, but there is also a greater threat of tornadoes this time.
Here’s the timing from one of our Futurecast models. As you can see there are two waves. The first in the morning and another in the afternoon. If the first wave in the morning holds together it could weaken the second wave in the afternoon. But if the sun comes out in the afternoon before the second wave moves through the afternoon storms could intensify. This is just an estimate of the timing, we will keep adjusting them as more data comes in.
It’s just a good idea to stay weather aware tomorrow. Have a way to find out if warnings are issued. If you have a weather radio make sure it is on and ready to go. Download our free app and alerts will come straight to your phone. And in the event that we do have tornadoes, have a plan. You will want to go to a basement if you have it, if not go to the lowest level of your home or building and the most central location away from windows. You can use pillows and blankets to help protect you.
Outside of the thunderstorms tomorrow, it will be a warm and windy day.
After tomorrow’s storms move out there is a great weekend ahead. A little rain lingers Friday morning and it will be cooler. Saturday looks great with a high of 70. Sunday expect a few more clouds, there is a chance of rain Sunday night.
A word about 4WARN Live Doppler Radar. We are the only station in Middle Tennessee with a live radar, the other stations use the National Weather Service Radar. So what does that mean to you? Our radar is constantly scanning the lowest level of the storm. The NWS radar is doing several tilts up to scan the entire storm. This takes 5 to 6 minutes. While this is provides useful information it does take time. That’s why can show you where the storm is 5 minutes earlier. 5 minutes could save your life. The red line means real-time radar.
I’ll have the latest on the storms on Channel 4 News at 10pm.
