The shaded map is definitely more pessimistic than the obs. Lots of 1.0s (mostly sleet) that are ignored in Interior E MA. 

Yeah....my parents had a couple inches in Hooksett and the maps have almost nada around there. I forget how the analyses are calculated...is it mostly remote sensing with satellite SWE data that is combined with actual depth observations? The sleet and ice is pretty dense so it should have a pretty high SWE. A lot of obs around NE MA are 0.25-0.30" so 3-4:1 puts you around that 1" of glacier mark.

Yep, took my dog out and it was like ice.

Our driveway and onto our road is a jagged glacier of death right now.   For some reason anything that melts from the edge of our property spills out onto the road and freezes every year.  It is odd since it is essentially level at that end     I almost fall on my ass every time I walk the dog

I think it's a combo actually (coop, survey, airborne, and modeled).

I like those maps overall. They are usually pretty decent. But I've noticed in that high LE ice pack they will underestimate and then in arctic sand it can overestimate sometimes...not sure what in the algorithm causes it. Arctic sand I can understand since it's prob measuring decent LE but it's low ratio garbage...but not sure why it can't "see" the sleet pack well.

They do sometimes get a little kooky late in the year too when you have the classic spring snow pack where woods and shaded areas might have 2 feet of snow with 5-6 inches of water in it but the typical bare patches in south facing torch slopes.

I think the remote sensing is based on LE, so the higher the water content the more pack it will think is there.

Me? The 2 choir boys smothered me under their robes this morning. They melted. I’ve been expecting an awful January. It is what it is on this o holy of days . I’m not thinking any snow in SNE until after Jan 20

Who said that?

A fair amount of banter yesterday in response to the post above.

 

I'm suddenly thinking a visit to Pit2 might be in the cards.
