Not severe, but I got a little thundershower yesterday evening/night (which ofcourse I went outside to video). Instead of rain, it gave graupel/small hail (when that started I moved inside).
The local NWS did put out a 'special weather statement' for that storm (basically thats a level below a severe warning)
Its still really early in the year to see lightning here now.

Another very rare high threat of severe weather for down south...

Yep.. I ofcourse saw & looked through the SPC storm outlooks for today.
At one point this evening I had 4 YouTube livestreams with stormchasers up, & was looking at radar.

  Have a feeling it might get a bit interesting here tonight !! I HATE night time storms !!!! They really freak me out !! 

Just the opposite here. I love a good nighttime thunderstorm.
Nothing like a good night lightning-show. Thunderstorms in general (but especially at night) is my one true love. .lol.

More severe storms predicted in the midwest tomorrow, and the next day, and the day after that...
(but not at the threat level of today)

This is a headlight bulb I think. I tried reverse image search but I didn't find anything else.

It's not much smaller than F14T12,  maybe an inch at most.
Here's a picture of F15, F14 and F10 lengths in T8 and T12.

I see three complete ones, and a fourth one that’s missing the canopy.

I will!

Yeah this is why I'm not as much of a fan of night time tornadoes. The sound of roar and the bright blue flashes clashing with the lightning flashes, and all the bright city lights shutting off... all of that is already scary enough. lol
My job actually just closed because of this incoming severe weather. I've worked there for almost 10 years total, and I've never seen them close due to incoming thunderstorms, at least not that I remember.

 I've been thru a few true tornadoes in my life and night or day , they really freak me out !  When I was around 6 , I remember being whisked from my bed in the middle of the night and hastily carried across the yard to the neighbor's house as they had a basement . After the storm , we went home to find that a very large beech tree took off a small portion of the corner of our house when it fell . That corner was part of my bedroom ! Another couple feet to the right and my bed would've been squished !! 

 Kinda what I was thinking . I've never seen the canopy before !

As much of a severe storm and supercell storm enthusiast that I am, I honestly don't like night time storms either, since I can't see the
danger as well unless lightning reveals it. lol
As of now the big storms haven't even reached Dayton yet, but we are all under a Tornado Watch. lol

Definitely a Holophane Square-Postop, but I've never seen one with a round canopy before.
