The 0z GFS gets Advisory level snow to most of us north of the turnpike in the LSV. Warning level snow for the mid & upper Susquehanna Valley this run.

For this week, a quick run through the 6Z/0Z models and the GFS, UK and HRRR still have some snow in the LSV. GFS has sig snow in the Northern LSV actually.   Rgem/CMC, Nam 3K and 12K, Euro, FV3 have backed the >1" snow line to the very top of the LSV (Pillowish) or totally out of the LSV.  The Nam's backed way off for the MSV as well.    @Cashtown_Coop, we are "out" on everything except the UK.   The Rgem was close for you at 0Z but now is nothing.

I think it was 27 said this morning about possible sleet fest.

Wow, you are up early.  The Euro dropped its PV into PHO idea.  It is still not a great look for snow here (next week) but you are no longer progged to get record temps.  

Sometimes I'm up at 1am Phx time. All our first deliveries are 7am. I never really thought we'd see temps that cold, although it has happened a couple of times in the past. This morning I had to remote start the Jeep due to frost. So far the low for today is 32.5 degrees.

Just saw the latest NAM's. Basically no appreciable accumulation even in Tamaqua.

Accumulation of what??  Go get some sleepy.....

I'd appreciate your likely 3-5 of snow/sleet/slop all day and every day compared to being lucky to get the ground white down here.

My expectations are low.   .2” would give me 1” season total so that’s my bar.  Sad lol

The new HRRR continues to be one of the snowier models for especially elevation.  This does not include sleet.

That would be quite the upset pulled off by the HRRR. I think in most situations like this, the snowfall amounts tend to be smoothed out over longer distances...for instance, if MDT recorded 1", UNV might record 3.5", IPT 4", etc. 

Hard to imagine Harrisburg getting warning level snow while I get nothing, but that's why we love the weather.
