I like how temps are already in the mid 30s. The worst type of marginal situations are when the surface temp is like 40F or higher and you have to wait for the surface temps to cool off at least several degrees. In this case though, many are starting with surface temps already not much above freezing.

Correct me if i'm wrong isn't the HRRR initialized of 0z and 12z data so each hour off those runs becomes less reliable? Either way, yeah it's fickle but can catch some last minute trends. Good luck down there.

HRRR uses the WRF Rapid Refresh as its parent model, which in turn has its own constantly updating analysis system (it's not just blindly initialized off a forecast time from a synoptic hour parent model, in other words). It also ingests data from aircraft, satellite, profilers, and radar winds every hour to keep a refreshed upper-air picture.

Yep, my temp just went up from 39 to 41 after the precip lightened up :arrowhead: Not getting my hopes up til I see snow falling. Alittle sleet mixing in here at the moment to. Good luck. The 13z HRRR looks great. Puts me in the heaviest snow band. Probably well overdone Id imagine.

It's a yo yo. I've been watching HUF and they were at 37º, bounced up to 39º and now back down to 37º with mod rain. Still 38º here, but 37º at LAF. Going to be an agonizing wait.

FWIW i had mentioned 12"+ amounts with next to nothing a county or two over yesterday, i still think it's possible.
