WRF-NMM model. I think the GFS is perfectly capable of handling ULL interactions. The short-term motion is what is causing the changes. Most likely from the beefed up energy in Texas.
Are you trying to say that this setup is impossible or just the GFS is bad at handling ULLs? Also keep in mind the GFS received a new upgrade since that time.
Spring Sandy
You actually don't want this? This is an incredible setup that should not be squandered in these parts. These are not really our caliber ... very rare to have the lows pass this close in the Spring. They usually go to our north or west.
