Shouting into the ether here, but am back to again tap down the 90°F dew point talk over Iowa earlier this week. Lots going on here with this plot, but it isn't corn, it is just bad data. Don't overthink it.
daryl herzmannI am too old to tap down the 90/90 talk. Please, get out your slide rule and compute how much water that is, even assuming a very shallow mixed layer above a corn field. Even if 90/90 was right for a corn field, this is way outside of the perf range of the sensor w/ 10 mile viz ob, case closed...

It is uncommon to see strong tornadoes in the morning in Wisconsin. Looking back from 1950 through April 30 of this year, the prime time for strong tornadoes in Wisconsin is between 2 and 7 pm (CST). Yesterday's tornado began at 10:56 am CST, making it just the 10th to start during that hour.
Jonathan ErdmanNWS-Green Bay rated the Appleton-Menasha tornado a preliminary EF3, with maximum estimated winds of 140 mph. Since 1950, per NCEI storm events database, that's only the 4th tornado rated F/EF3+ in either Outagamie or Winnebago Counties. The last one, there, was April 27, 1984.

We've received reports of another lightning fatality in Wisconsin this morning. This would be Wisconsin's 2nd lightning fatality of 2026 and 3rd in the last two years. The victim was trimming trees when a thunderstorm developed nearby. www.wmtv15news.com/2026/07/27/2...
