Drying Out. Next Rain Event Late Wednesday (but really, Thursday).

Last night’s storm reports weren’t from storms but from the Wind Advisory. “Non thunderstorm-winds,” they call it.

Rain reached 2″+ in spots yesterday. Creeks and streams rose quickly and fell not as quickly. A few rivers reached pre-flood “action stage.” For more on that, this.

Insufficient storm-making instability prevented last night’s “storms” from tapping off-the-charts storm shear. More than a few storms rotated but fell short of producing a local tornado.

Now We Dry Out

Sun today, low to mid 60°s.

Next Rain Event Thursday

May begin Wednesday night. But mostly a Thursday thing.

A few strong thunderstorms with gusty winds and heavy downpours may occur Wednesday night -Thursday. (NWS-Nashville)

Models show unfavorable winds aloft. This “limit[s] confidence in any more than a marginal severe [thunderstorm] threat developing across any part of the lower MS Valley, TN Valley, and Southeast on Day 5/Thursday.” That’s from the Storm Prediction Center. Several days away, expect changes, but nevertheless that’s a good sign right now.

Still, another soaking rain. 1.5″ to 2″ total:

20.91″ has fallen in 2019. 11.93″ more than normal.

Are Snow Chances Over?

I see no model support for a surprise late winter/early spring snow.

Although, there is a slight “it may get cold enough” signal in the Euro ensemble data toward the end of March. This means very little. Merely a hope glimmer for sled enthusiasts.

But consider Nashville records:

  • Latest measurable snowfall: 1.5″, April 25, 1910
  • Latest snowfall, 4″ or more: 4.5″, March 24, 1940
