The NAM has been pretty consistent with this over Omaha for 2 days. I think it is on to something like a frontogenesis band setting up on top of or around Omaha. It will be interesting to see if it’s right. Other models have started joining in.
It looks like all of the models are coming into an agreement with the bullseye being Omaha Nebraska. Even the GFS, which had been the outlier, is in agreement. It will be fun to follow.
