Looking at the DSM NWS forecast discussion it would seem they are being quite conservative about central Iowa. They are thinking 3 inches or so maybe 4, but most models I’ve seen are showing 4-7 inches here, with the 18z NAM closer to 8 inches and the GFS at over 6. The argument is that it’ll be columns and not dendrites, but I have a feeling they might change their minds and include us in a Watch tomorrow.
