I don’t know what the GRAF is but damn 

I’ve seen it used on WFMZ, but have no idea how accurate it is.

FV3 has a squall rolling thru in the early Saturday hours, maybe a quick coating in spots extreme se pa:

Last time I saw it used was 2020 storm and it did well. Obviously we’re not getting 20” unless this is a jan25 2000 bust

This has been one of the more interesting storms I’ve tracked. The high end ensemble members kind of make me depressed because it just shows what a full phase could have done

The Global High-Resolution Atmospheric Forecasting (GRAF) model is a propriety, physics based, numerical weather prediction system developed by The Weather Company (an IBM Business) in collaboration with the National Center for Atmospheric Research (NCAR).

12k NAM came way north for the late weekend system. Appears warmish at the start.
