That was the best storm here in quite a long time. Incredible multi-tiered gust front, with the lower clouds practically scraping the earth as it marched in very quickly. Had a period of 50-60mph winds and blinding rain. Rain gauge says we got a little under a half inch, but I'm guessing quite a bit of it blew over the rain funnel lol. The growing concern now is the convection in southern IA/northern MO. The LLJ is going to feed those puppies all night, so where the storms eventually align is going to be in for a lot of rain. Still too early to tell where that will set up exactly, but it looks like southeast IA up towards the 80 corridor east of the QC.

Quite a nice synoptic wave moving through for late August. Looks like southern Iowa is starting to recover quite rapidly now as the WAA stuff has lifted out quite quickly. Nice plume of steep mid lapse rates upstream coming in from the Plains should quickly re-destabilize central and southeast IA by later on today. Definitely expect a nice round of convection or two after the current one overhead moves out. Could be quite an active night. DVN has gone with a FFW for the whole CWA, which is prob a good idea. If there's some training of storms like what was seen last night in WI someone in the DVN or LOT CWA may be in for a rough night lol.

Kind of lol worthy that we're going to have a hard time building decent instability for tomorrow's setup over Iowa after all the extreme instability we've seen the past several weeks beneath zero wind shear. We finally get a potent little vort and can't muster jack squat for cape. #****bag2018season

A little snippet from the DVN AFD back on this day in 2011. Can't even fathom something like this being written now with how slow this year has been. Almost doesn't seem possible. . SHORT WAVE COMBINED WITH FRONTALBOUNDARY AND HIGH CAPES SUGGEST POTENTIAL FOR EXPLOSIVE DEVELOPMENTOF THUNDERSTORMS IF CAP BREAKS. IF THIS SCENARIO PANS OUT THEN ADESTRUCTIVE DERECHO WITH WINDS OVER 100 MPH IS CERTAINLY POSSIBLE.CORFIDI VECTORS WOULD TAKE THE THUNDERSTORMS SOUTHEAST ACROSS MUCH OF THE DVN CWA.

Nice, that will make for a real nice fish fry.

Wow, poor lower Michigan has gone over a million days without a tor watch. Brutal.

Very nice shot!

Yep. Started way out in western NE about this time last night. Still going (although not severe anymore) and entering northern Mississippi. https://mesonet.agron.iastate.edu/current/mcview.phtml?prod=usrad&java=script&mode=archive&frames=200&interval=5&year=2018&month=6&day=28&hour=0&minute=30

That complex is plowing right through that extreme surface moisture axis. SPC meso analysis shows PWs over 2" all along that axis, so rainfall rates are likely exceptional with that line.

The coldest windchill by state thread needs to be renamed the zombie thread. The thread that will not die.

This is more long term, but the Euro has been pretty consistent in showing big cape over the corn belt/Midwest later next week. The 6000J/kg max value on WxBell is exceeded in some cases.

Maybe since late May and June has had a mid to late August type pattern when we get to August maybe we'll get an active May-June type of pattern.

This year has a chance at being the first that I haven't even gone on a backyard chase since 2005.

Wow, I can't imagine experiencing something like that. Back then most people didn't have AC either, so sleeping had to be pretty difficult with such warm nighttime temps.

Man, every time I see your user name this always pops in my head lol.

Think I'm gonna start a thread about record heat index temps next January.

Well done. Capturing even a "bird fart" tornado in 2018 is a pretty nice accomplishment.

The couplets looked pretty nice on radar, nice and tight. Problem is though the lowest beam height is over 5500ft out that way.

Very nice! WAA wing storms exploding just west of here. The cell just to the west has a small hail core already. Could get interesting here sooner than I thought.

Congrats! Looks like you guys are getting some pretty nice action this eve. Have what may be the beginnings of a WAA wing from just east of the QC back up towards Maquoketa. Thinking we're gonna get smacked here pretty good by the main line in a few hours.

Some new cells starting to pop north of Grinnell down towards the better instability. Nice ML LR plume nosing into the southern half of Iowa. The southwesterly LLJ should keep things blowing up on the west side of the complex for much of the night. Parts of eastern Iowa could really get dumped on tonight. The LR plume and LLJ should keep the strongest storms right about where SPC has the enhanced placed IMO. Waterloo/CR/Muscatine would be my favored area for the heaviest rains tonight.
