January 5-6 Thing II: STORM MODE

By hour 12 you can already tell where the hrrr is heading.  If you pull up the rgem for instance it’s night and day apart by hour 12. That doesn’t mean it’s right but if it fails it’s not because it’s out of range. The divergence happens in the first 12 hours.

6z Hrr has 12" snow depth for DC by hr33. Could be a 15"'er. Anyone know why the RAP and HRR are on this page, 12-15" snow depth is pretty significant - although the mesoscale of those models beyond shorter ranges isn't good, I might expect other models to juice up a little in the morning.

To that level I would be very surprised. A little yes. 

Even as a meteorologist, if the HRRR is even close to right for this setup, I will get a custom, "I <3 the HRRR" T-shirt and wear it to work on another set of night shifts. I don't think it'll be right, but this is getting bonkers.

HRRR goes bonkers on frontogenetical forcing in a cold column. I’ve seen it both overdone and underdone and when it busts it’s usually a bad one. The elements are there for heavy snow but we are not seeing a true upper level phase that would produce this type of snowfall. More so a 6-10 inch event with a few pockets of 12 is more likely in this setup. 90% of our snow will fall between 2 am and 10 am, purely WAA with frontogenetical banding. Beyond that it’s more complicated with the pass of the upper low and development of the coastal which will not phase.
