Not much better here with just 0.01". Had noticed models weren't showing much and was hoping they'd be wrong. At least the dryer areas of Iowa were getting the heaviest amounts lately. And far se. Iowa which had been the wettest earlier was missing out more in May and dryer than most of the state.
Multitude of factors. Inception of Niña/E-Hem LF forcing in tandem with descending +QBO, -PMM/+AAM (which modulates ITCZ/HC width), and +DMI/+IOD tendency which will focus convection towards the IO side of the IPWP heading into the heart of summer.
Everything is set up the worst way possible. A miracle is always possible, but those are few and far between these days.
June might have a few cool shots left in the tank (eastern US first half of month then western US second half) but that’ll likely be the exception rather than the rule IMO.
