Literal Rochelle 2.0, lol. Unless I'm missing something, the UDH on the HRRR isn't really that alarming. It was showing phat red/purple streaks in Iowa on 7/14 for example, or even for yesterday's Boscobel tornado although it placed that simulated sup too far NE at least on the run I saw. However, I've noticed you can't really key in on that particular product until the day of, especially with these mesoscale-driven summer events.
Then further out, 3KM NAM's scenario for Tuesday does not exactly jive well with SPC's Day 3 outlook.
