Upper 70s dews over here in Iowa even though the corn is still short and the beans are just popping up.

Yeah, this MCS really put the kibosh on the hot and humid day across Iowa. Even the Ames/Des Moines area, which received no rain, are firmly within the cold pool and stuck in the 70s.

The HRRR can be a good model, but it appears to be terrible with these low-shear, cold-pool-driven MCSs. The model struggles to see them and refuses to keep them going beyond the first couple hours of each run.

The line of storms had a little flare-up just west of CR and it moved in just quick enough to beat the subsidence racing in from the north, so I picked up 0.34" of rain and got some lightning and thunder.

Morning line of storms diving south through Iowa just crapped out as it approached Cedar Rapids. It's a pretty classic scenario in which the western part of the line remains strong and back-builds into the instability while the eastern part gusts out. It just hasn't been our month, getting missed in every direction. We may finish June nearly 2 inches below avg. Rochester, MN just got nearly 5 inches of rain overnight. I've received 3 inches all month.

The dewpoint here is up to 74º, the highest so far this season. It's still unknown how tonight's MCS will pan out. There is currently more action dipping into Iowa than models predicted, which could benefit my area tonight.

0.30" overnight. MO/KS and points south are gobbling up much of the good MCS action.

It's 10-15 degrees cooler (both temp and dew) than models predicted a few days ago.

I like DST.

0.53" of rain today as we, once again, got stuck under the general rain shield on the north side of the MCS. This has been the theme this spring/summer. The slow-moving disturbance today has kept this area in the mid 60s, so it has been pretty cool. Models had been showing the dewpoint rising into the mid to upper 70s on Saturday, but that now looks unlikely. The euro is now showing mid to upper 60s, with temps only in the 70s. For the most part, if we want summer heat and storms this year, we have to go south.

The euro also has mid to upper 70s dews on Saturday. It has been so pleasant for much of this month, that will be quite a slap in the face.

And the very next run has the MCS tracking from Missouri to the Ohio Valley.

1.05" of rain in my yard this evening, our first good rainfall this month. We still haven't had anything very strong this year. DVN issued a warning this evening, but it was not necessary.

My county was severe-warned, but the wind maxed at only 30-35 mph.

I also picked up 0.30" of rain, most of which quickly fell from a decent line of storms this evening. There was a bit of pea size hail and gusty wind.

Yeah. While the weather has been pleasant and excellent for the garden, it's tough to watch our peak storm month waste away.

It is looking generally uneventful here for the first half of June... quite the change from May.

Well, so much for that. The severe potential has been shifted south and west. We've been downgraded.

Tuesday evening looks pretty active over here. We're in the enhanced area now, but Des Moines thinks a further upgrade is possible.

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.

12z Euro - Friday & Saturday highs Friday Saturday

While I've casually followed the Mississippi flooding, I kinda forget about it because the rivers just to the west, around here, are not high at all. I just went down to Iowa City and the Iowa River/Coralville Reservoir are actually rather low. All the recent heavy rain has been from here south, with not much up in northern Iowa where all of our rivers begin.

A hail core passed just south of Cedar Rapids. I received a bit of heavy rain, but no hail.

There have been several nickel-size hail reports so far. Cedar Rapids was just put in a warning for the cell approaching from the sw.

Two runs in a row the euro has shown another upper midwest bomb cyclone at day 8/9.
