I was just looking at the rgem soundings under the death band and it has really steep lapse rates from sfc to 925mb...it’s just not credible. That should literally be isothermal under that type of precip.
If 925 was a torch then it would be more believable....and as an aside, the rgem is a little warmer at 925 than other guidance but not enough to explain all the rain. It is still getting below 0C in that level.
