There is a strong tornado on ground just sw of Iowa City.  KGAN has their chaser live right next to it, live on air.  This is awesome.

Hopefully we can get something to go nearby in the next hour or two.  If not then it will be a long wait.

As quickly as that Iowa City cell formed and became tornadic you just might be in business.

May be cycling. Last grab on velocity didn’t look as good. 

It definitely lifted. There have been a lot of close calls this week.

And man that 0-3km helicity is 300 to 400 over much of northern IL, Chi town and nw IN should anything form or move into that area.

HRRR seems to be on a downward trend with the early evening development in the area though.  That was my reasoning earlier for central/southern LOT cwa potentially being favored a bit... it was assuming vigorous (re)development along the warm front from around now through the next few hours but that is looking iffy.

Storms beginning to fire around Macomb and in ne MO radar hole area.  Wondering if northern MO will be put under a tornado watch for storms approaching from KC or for development farther east.

so I went just down the road with a good view...as soon as it started going up...nice anvil moving in from the SW...I turned all phones and internet off to go "blind" thinking it would blowup. it got closer and closer..but there was a problem...no lightning or even thunder.....no mammatus clouds in the anvil...

 

I got a few sprinkles on the wind shield form the dying anvil...juts got home and checked the radar...looked decent in Fulton county but POOF confirmed with that cell..but storms to my NW

..

such is the luck of the draw at times.  I think overnight might be more interesting but probably MCS action.

SPC added an ENH/30% wind area on the new outlook.  Not clear to me how widespread of a wind threat will evolve so I'm gonna hold my tongue from further comment lol.

..Lower Missouri Valley into Upper Midwest...
   Across northeastern Missouri into the vicinity of a warm frontal
   zone across parts of eastern Iowa and northern Illinois, it appears
   that an area of enhanced forcing (associated with a convectively
   generated or enhanced mid-level cyclonic vorticity center now
   developing northeast of the Kansas City area) may still support an
   upscale growing convective system later this evening into the
   overnight hours.  This may be accompanied by another swath of strong
   to severe wind gusts.
