1:50 Wx Update: A slightly higher storm threat for Wednesday?

WHAT: Strong storms?

WHEN: Wednesday afternoon (noon to 5:00)

The Storm Prediction Center has just issued a marginal risk for severe weather for parts of Kentucky and Tennessee for Wednesday afternoon. This is the lowest of the severe weather threat categories, but it’s an upgrade from the “general thunderstorm” outlook issued earlier today for the same area. The risk is mainly for storms that may produce hail to one inch in diameter.

At this time, that risk does not include the plateau but it is very close by. It’s basically for those areas just west of the plateau and north of I-40. I should mention that this risk may be either upgraded or expanded tomorrow and that is why I mention it now.

This is not a severe weather outbreak situation, by any means, but it is something to keep in the back of your mind.

A warm front will be lifting north tomorrow afternoon across our region. At the same time, stronger upper-level winds will move over. The combination of a surface frontal feature and better upper-level (atmospheric) dynamics could lead to a strong to severe storm around our region.

While warm fronts are not notorious severe weather makers, they have been known to create hail-producing storms, as well as brief tornadoes.

I’ll keep a close eye on things. Right now I’m not too concerned but I don’t want us to totally ignore this. I’ll have another update on this situation later on this evening.

The rest of our afternoon and evening is looking cloudy but mostly dry. I can’t rule out a passing shower but many of us will just be cloudy.

Keep in mind that a better chance for strong storms comes Friday morning. I’m watching that closely too.

Enjoy the rest of your day!
