Rain Tonight, Clearing Tomorrow

Editor’s Note: Y’all crashed this site a few times yesterday with 50,399 page views. I’m working through various possible low/no-cost solutions to bring stability and quality during these high volume events. So, for now, we’re going to go light on the graphics and bells and whistles to help prevent another crash. read more

Severe Weather Still Possible Tonight . . . & Tomorrow?

Flooding Concerns

Tuesday Afternoon/Evening Severe Weather Possible

One more day of this nonsense, y’all.

Another round of severe storms is possible, thanks to another slice of energy thrown at us from the massive low pressure center spinning way off to our NW. read more

Watching The Supercells

To help ease the “crash” problem (we’ll fix this issue in the future), I’ve pared this page down to essential info only.

  • A Particularly Dangerous Situation” (PDS) Tornado Watch is in effect for southern Middle Tennessee until 9 PM. This includes those counties just S of Williamson. Both Davidson & Williamson Counties are currently excluded from the Watch.
  • There’s a “boundary,” stretched west to east across Middle Tennessee, separating warm/humid/unstable air to the south from cooler/less humid/more stable air to the north. Those along and S of the boundary are included in the Tornado Watch. Those north of it are excluded from the Tornado Watch.
  • At 2:30 PM, the boundary was located about 40 miles south of I-40. The boundary is mostly stationary, or maybe edging very slowly N. Storms feed off the warm/humid/unstable air currently located S of the boundary. This means we are currently on the “good” (North) side of the boundary.
  • Tornadic supercells in central Mississippi at 2:30 PM will move rapidly NE into southern Middle Tennessee around 4 PM. We will be watching those supercells in case (1) the boundary lifts N into Nashville, paving the way for the supercells, and/or (2) the supercells punch N through the boundary and into Williamson, and maybe Davidson, Counties. We’re hopeful these storms, if they continue their current course, will miss us comfortably to the south and southeast. We’re also hopeful we won’t heat up fast enough to develop our own supercells.
  • No Warnings will be posted to this website. Follow @NashSevereWx on Twitter, and multiple other reliable weather sources, for more information.

    Hail, Tornadoes Possible This Afternoon/Evening

    Frequently Asked Questions

    1.  Is it safe for me to drive from “x” to “y”? — Keep in mind we’re only looking at two counties. If your travel takes you elsewhere, I’m not the person to be answering that question. I also am very uncomfortable telling you when you should travel. My goal is to give you the information you need, and leave 100% of the decision to you. read more

    More Details on Monday’s Severe Weather Situation

    Early EveningRain, Non-Severe Thunderstorms Likely 

    The HRRR Model (High-Resolution Rapid Refresh Model) has been been too-soon with the ETAs of this advancing rain system.

    T’Storms Today; Supercells Forecast Monday

    We start with this from our NWS-Nashville:

    TodayRain, Non-Severe Thunderstorms Likely This Afternoon

    Last night, I wrote that the Hi-Res NAM weather model thought it would rain this afternoon. Skeptical, I wrote that I’d wake up and see what the morning runs of the HRRR said, because the HRRR usually does a decent job. Well, here it is: read more

    Round 1 – Sunday Afternoon

    New Info on Severe Weather Potential Sunday, Monday, & Tuesday

    Special Severe Weather Update

    NWS-Nashville’s Afternoon Forecast Discussion led off with this:

    As we wrote this morning — We want to balance the goal of raising awareness/encouraging preparedness with the risk of over-hyping this event. The details of what will happen remain fuzzy. There is significant potential, but answers to questions about ETAs, local impacts, and types of storm modes (tornadoes, hail, high winds, flash flooding) do not exist. This is a situation where the storms which form Sunday will impact what will happen Monday. What we see Monday will impact what happens Tuesday. read more
