1/3 Snow Squall Potential

can you show snow totals just because?

The run ends as the precip moves in, so totals won’t show anything. Extrapolate the HRRR at your own risk but I do like that it shows the possibility of more than just a quick burst

I'm hesitant to buy the HRRR area of a stratiform shield.    And I'm tossing anything that isn't a hi-res model, as this is a set up with a couple of bands of showers turning to snow squalls along the cold front, driven by dynamics and surface convergence, and enhanced by some steep low-level lapse rates.    The NAM Nest simulation certainly looks plausible:

I was parsing through DESI earlier and looking at the 1D plots and noticed a small SBCAPE signature over my hood so I took a spatial look. There will be some sneaky good snow shower/squall activity with this one. I wouldn’t be surprised if areas north of I-70 grabbed a quick 0.5-1” with this type of setup. I think further south will be tougher for good accums, but flakes will likely fly anyways to give that winter feel in the air. Hopefully people enjoyed the milder temps recently. The bottom drops out soon and it won’t be coming back anytime the next 10-14 days, maybe longer.

Not to be a negative nancy but aren't temps going to be an issue? I don't see stickage middle of the day with temps in the mid to upper 30's.

 

Temps likely run a bit warm, but I’d be paying more attention to timing due to the friday PM commute

@nj2va@IronTy anyone headed up to deep creek the next few days? Tonight into Saturday looks pretty primed for 6-10” with the clipper energy 

We were up there for Christmas so unfortunately I won't be there this week.  I'll be up there in a couple weeks to do a construction inspection so hopefully they'll still have some snow to snowshoe around the property.
