NWS-Nashville has teams in the field again today. They are surveying damage, distinguishing straight line wind events from tornadoes, and rating tornadoes on the EF scale. They’ve counted 7 tornadoes in Middle Tennessee from Saturday morning. We think that number will probably be higher. Tornado surveys will probably not conclude until Tuesday. We will bring you that information as it comes in.
NWS-Nashville is out surveying storm damage. Yesterday they rated the Dickson tornado EF-2, entire path length not yet determined. Early this morning they rated the Kingston Springs tornado EF-2, 125 MPH maximum wind, 400 yards wide, 10.5 miles long, 1 injury. Surveys will continue today. We will tweet updated information.
We are all done with rain and severe weather. If you are waking up to any damage, tweet a picture of it with the location using #tspotter. Storm surveys will be conducted again today to determine where we had tornadoes vs. where we had straight line wind damage. We will tweet updates as that information comes in.
We’re writing this at 5 AM, with the leading edge of the storm out of Davidson and Williamson Counties, and along with it, the damaging straight line wind and tornado danger. Heavy rain will continue in S/SE Will Co, but that should remain below flash flood levels. Lightning will continue, too.
Tonight’s second Tornado Watch has been issued.
The first Tornado Watch was issued earlier tonight. It had an expiration of 2 AM.
The tornado threat will extend after 2 AM. So a second Tornado Watch has been issued. This one expires at 5 AM. That does not mean the tornado threat will be over at 5 AM. Do not interpret this as an all clear after 5 AM. It’s possible a third Tornado Watch will be needed. Watches typically only go on for 6 hours.
The Storm Prediction Center, in coordination with NWS-Nashville, has issued a Tornado Watch for Davidson and Williamson Counties.
This Watch will continue until 2 AM.
Important! A second Watch (Severe Thunderstorm or Tornado) may be (probably will be) needed after 2 AM. We will not be clear of the straight line wind or tornado danger until probably 9 AM or so. (SPC doesn’t issue 12 hour long Watches for anything; too much can change.).
This blog describes to you, fellow neighbor, a low probability of a high impact event. Basic precautions are necessary.
Now Until Dark
Windy, 15-25 sustained, with gusts to 40 MPH. A Wind Advisory is in effect today (expiring at midnight).
Starting late tonight, our weekend weather maker will start moving into our area, starting off with some spotty showers.
These showers will hang around all day Friday, but they are pretty spread out. You might get a lot of rain, but your coworker might not. Some of these individual cells also could be strong enough for some thunder and lightning, but we aren’t expecting anything severe quite yet.
We’re staying dry and getting up into the low 50’s today. The sun stays until Friday. Temps heat back up to the low 70’s by the end of the work week.
A cold front is forecast to come through Saturday morning that has the potential to bring some severe storms our way as it pushes through. The SPC has everyone west of the Cumberland Plateau in a severe weather outlook for Friday. Our counties are in a slight risk (2/5 scale) for severe weather. This translates to a 15% chance of severe weather occurring within a 25 mile radius of us. Main threats are damaging winds along the front as it comes through (60+ mph) and isolated tornadoes.
Temps dropped like a rock overnight thanks to yesterday’s front. The high today will be in the mid 40’s, so yes it is chilly. Lows overnight should stay just above freezing, but a few spots may get down below freezing.
