Wednesday 7:00pm - EF-1 Tornado Recap

By Chief Meteorologist Kevin Lighty

Hello everyone and thanks for checking out the KSPR weather blog.

Well last night turned out to be an interesting night for all of us who live in and near Springfield.

A confirmed EF-1 tornado touched down right through the middle of Springfield last night around 10:50pm.

Below you can see the path of which the tornado took. Around the Republic Road & Scenic Avenue area. More damage near National Ave. and Sunshine St. and more at Fremont and Catalpa.

The tornado was not on the ground the whole time but instead sort of bobbed up and down along the path causing damage.

Damage was significant in those areas hit where roofs were torn off and trees uprooted and stoplight arms swung in different directions.

Below is a look at the velocity mode of doppler radar which shows the obvious couplet where the red and green are right next to one another. This is where circulation was present.

Thanks to Jim Sellars and STORMLAB for the images.

First scan at 10:41 just before the circulation got going.

Time of the tornado 10:45pm

By 10:55pm... It's gone!

What made this situation different was how the circulation was right near the surface and not 10,000-20,000 feet up like rotation in many storms can be found.

The way it works is circulation is found aloft and then sometimes makes it to the surface as a tornado.

In this case it was the opposite the circulation basically started from near the surface and worked its way up.

Also when looking at radar. The beem that shoots out goes up and curves because of the curvature of the Earth. It typically sees that rotation at the usual 10,000ft or so.

So this just goes to show that when a Tornado Watch is issued and storms are present you need to also be aware of what is going on even if a warning has not been issued.

 

Well as far as weather goes over the next few days temps will be quite nice both tomorow and Friday with highs in the upper 50's.

The HI-Res futurecast is picking up on our next chance of precip which will come on Friday as another system heads right through the Ozarks. No severe weather is expected.

Also wanted to share a nice picture from the Laclede County Office of Emergency Management who in their battle room they have KSPR 24/7 On Demand Live Weather Stream up
