Nam at hour 45. I would like to think if that low were to move slower and the colder air to push in quicker a lot of this would fall as snow. Not counting on that at this point though.
That’s the rgem 18z. The nam isn’t working at the moment on tropical tidbits.

Damn, now how did I not see that? I blame it on the Benadryl.

Better hope NAM was on crack and not a trend setter

How did this go so bad that quickly, worse and worse every run, now 0 inches of snow here and 90% rain.
Once it’s starts going bad this close it doesn’t come back.

Park that low over west central AL and let it keep turning. Lol. Do these ULL’s ever tend to slow or stall?
The big issue is the low is really not closed. NAM has been most inconsistent with this. It's trending toward the goofus and doc

RPM
RPM is meant to go farther out that that. It's really not that crappy, it's decent. It actually goes out 72 hours.

GFS followed suit sorry for the folks in MS/TN still some wintry precip but a sloppy wintry mix of all P-Types
Well the famous James Spann says this about it:
"RPM: Rapid Precision Mesoscale model. A numerical weather prediction system based on the Advanced Research Weather Research and Forecast system (WRF-ARW). RPM generates forecasts out to 24 hours with updates every 3 hours in the United States and every 6 hours outside the United States. Precipitation forecasts are calculated from half-hourly instantaneous precipitation forecasts output by RPM. RPM model output is not available to the pubic; but we have full access and use it extensively in our forecast products."

GFS is slightly farther south than 18Z with the frozen precip.
