HRRR has me at almost no rain whatsoever up to right now and so far I'm at 2.04".

Unless I'm looking at the model incorrectly, it's wayyy off for my specific location.

HA! As soon as I posted this I got the flash flood warning on my phone

There's your west wind barb. It's a closed circulation albeit still weak. Maybe the Icon as a global model isn't off its rocker persistently showing a closed low (will have to note that it does run a little high for intensity) and the HRRR/RAP/GRAF models aren't so bad after all.

Located in Metairie, Louisiana.

NW GOM is not very far away. Might be good to take the plane out for a spin. And the NHC folks are rather bored. This the best thing they have had to look at in weeks.

What is kind of puzzling to me in the NHC Tropical Weather Outlook is the statement that the area of low pressure was producing "widespread disorganized showers and thunderstorms". Is it because the low-level circulation and mid-level circulation are not "stacked" or aligned (as Kory alluded to on page 3) The banding looks pretty "organized" (in my opinion).
