Will depend on how much backside stuff develops from the synoptics. Usually models overdo that IMO in the warm season. But it's a potent s/w. I think the bigger totals are more towards the low center.
That's an option. I was hoping for something else. I looked at cocorahs, but that didn't help. I guess metars would work, but trying to fill in the gaps in between.
That slug of rain south of SNE is driving the watch. Looks good to me. Jack west with the steady rain and then the more potent stuff with a local jack near low pressure center.
Regardless another unnecessary widespread soaker.
