I’ve added the afternoon map updates from the BTV NWS below for Winter Storm Harper.  There was a Winter Weather Advisory out near the Saint Lawrence Valley, but that been filled in with a Winter Storm Warning now, so that’s the level of advisory across the whole area.  The point forecast here suggests total accumulation in the 12-20” range, which seems to jive fine with the latest projected accumulations map.

Event totals: 8.1” Snow/0.78” L.E.

 

It looks like snowfall generally was running in the 1”/hr. range overnight.  Although the flakes were all quite small (1-3 mm) and grainy at observations time, we’ve actually got some larger ones up to 15 mm falling now.  The snow density overall was a bit above the 10% H2O I was getting last night, and waking through the snow during observations it certainly had some upside down feel, so I think there were some larger flakes in the stack at some point overnight as well.

 

Details from the 6:00 A.M. Waterbury observations:

New Snow: 6.6 inches

New Liquid: 0.63 inches

Snow/Water Ratio: 10.5

Snow Density: 9.5% H2O

Temperature: 10.9 F

Sky:  Snow (1 to 3 mm flakes)

Snow at the stake: 26.0 inches

How much at the stake? Must be over 30"

Yes, we’re actually right at 30” now – that’s the top of my main stake, so I had to insert the taller one now since it could easily go over.  This snow has been around 10% H2O as well, so it’s not settling a ton.

Measured 4" at midnight, then all hell broke loose with the winds over night, seemed like 30-50 mph gusts all night and into early AM. Drifts and a few bare spots in yard. Hard to really tell how much..everything seems blown off the top into the woods, it was definitely coming down pretty good overnight with the winds.rps20190120_115404.thumb.jpg.3fa789f0ab9b0b3684b20c6f23dc0ccd.jpg

I’m not in a great wind spot to begin with but I haven’t noticed any wind to speak of. 

Yeah, had some strong SE winds last night which are always bad here.  I honestly didn't think they were going to be that strong.Should have almost been a high wind warning for the western slopes down here.

Picking up a couple inches of some nice dendrites  on the back end now.

Up to 27" here, with today's 10-11".  Pack is solid except for today's pow, though even that has been 10:1 (at low singles) due to tiny flakes.  The stake goes up to 61" before I'd have to think of an extension - tops here has been 49" in 2009.
