Afternoon update on Tuesday night’s storms

Confidence in strong storms affecting the Cumberland Plateau Tuesday night continues to be high. Straight-line winds will be the main threat, along with some possible hail that could reach severe limits (>1″ in diameter). The tornado threat looks very low, but not zero.

Wind advisories have been issued for the western half of Middle TN for Tuesday. Those may be extended eastward to include the plateau as we get into Tuesday. Gusty south winds will be very likely tomorrow.

Below is the updated NWS map of the severe threats. Notice the plateau is right on the eastern edge of the threat. The greatest threat is west of Nashville, where storms will occur before dark and when daytime heating will really help fuel the storms.  Highs in Nashville are expected to be 80 degrees on Tuesday.

Below are the hazards expected. Again, the tornado threat is low, but the threat for damaging straight-line winds is high enough to cause concern. Winds could gust to 60 mph in stronger storms.

And here is the current thinking for the timing of storms. Hopefully, we can get these storms out of here by midnight. As always, I’ll be awake and online until the threat has completely cleared the plateau. As soon as the threat passes, I’ll pass that info along on Facebook (https://www.facebook.com/thunderchaser) and on https://meteorologistmark.com/.

You all have a great evening! Get some sleep tonight. We may be late getting to bed tomorrow night.

And there’s already hints of a rain/snow mix Friday night. More on that later……
