Wednesday – Hot, Mostly Sunny, Strong Storms Late – Wake Up 70, High 90
No rain, but our heat index (“feels like temp”) will be in the mid 90s.
Don’t let the mostly sunny day fool you. Late Wednesday night, a line of thunderstorms, called a MCS (“mesoscale convective system”), will approach. Here’s what the Hi-Res NAM thinks it will look like on radar around 7 PM.
Weather models do not agree on the ETA of these storms. Some models predict the storms will arrive 12 hours later than other models. Also, we may see two rounds of storms.
Do not think that the storms will be “weak” given their night-time ETAs — all forecast models say severe weather ingredients will be in place despite the sun going down.
These storms will be strong, and potentially severe. The Storm Prediction Center has placed us in its “Slight Risk” for severe thunderstorms:
Damaging winds are the main threat. Hail, and maybe an isolated tornado, could be possible.
Be sure to turn on your NOAA Weather Radio or any other device that can alert you if severe weather is in our area. Have an app that will wake you up (see the scrolling banner, above, for an iOS app).
The Weather Prediction Center expects over 1″ of rain.
Our local NWS office forecasts 0.85″ for Nashville and 0.76″ for Franklin.
Thursday – Clearing Out, Partly Sunny – Wake Up 72, High 84
After the rain, drier air will arrive.
