That makes the last 3 snow events last week where they had the highest around...interesting to say the least

The observer there seems on the ball most of the time... the event before they definitely were in a good spot though.

I imagine your depth is probably spot on with their depth.

Is that theu guy that's been the long time co-op guy for like 20yrs?

yeah that coop has been there for a while... one of the most reliable in the state.

If he's clearing every 6 hours (like he's supposed to) then the slightly higher totals would make sense. He's also in a good spot at 750 feet east of you a bit.

Well I'm feeling good with the Euro giving me 1 inch plus QPF all or mostly snow, the GFS .5+ as snow...not caring about the NAM so much now unless it trends in my direction then I ride it. Just have a hard time seeing this not verify a little colder than models show given a 20 inch snow pack, below zero temps tonight and a very cold night tomorrow before the clouds move in. I'd think the first .3 of qpf is higher ratio snow given the cold air. The ratio would worsen during the storm but we might get 4-5 inches quickly with strong waa.

Really hard to not be optimistic up here. Suspect we all verify a little colder than expected....climo in New England, mid January, deep snowpack and fresh strong antiecedent cold. Correction vector is colder. Erection vector pointing up.

Now to me that isn't necc accurate. Granted it is how much has fallen..but it's not the same as what's on the ground even right after the snow stops..so that explains to me the diff. I think what is on the ground(hard surface) is more accurate than clearing every 6 hrs as far as saying what is on the ground

But that's not how you're supposed to measure. If he's recording snow depth and total snow than what's the difference?

I guess my point is if he stuck a ruler (yardstick) in the new snow..would it have said he got 29 new inches of snow? I don't think it would have...Not saying it's not right to do it that way..but it makes sense to some degree I guess as to why totals are higher than those that aren't measuring on a snow board

No, of course not.

Saturday AM you could have put a thermometer 6" above the ground and got a temperature 5 degrees colder than at 2 meters.

There are observing standards for a reason... so everyone follows them and we can compare apples and apples.

If you don't like the standard than just measure both depth and off the board (which is what the coops do as well!).

Well then which number are they reporting as their snow amount from said storm?

GYX PM update paints a wintery picture.

FOR NOW...THE BEST FORECAST GUESS IS THAT FOR THE

36 HOURS FROM TUESDAY NIGHT THROUGH WEDNESDAY NIGHT...THERE WILL

BE A WIDESPREAD AREA OF 4 TO 8 INCHES OF SNOW AND SLEET WITH

GENERALLY LESS THAN 3 INCHES RIGHT ALONG THE IMMEDIATE COAST. ICE

ACCUMULATIONS OF ONE QUARTER TO ONE HALF INCH ARE MOST LIKELY

ALONG THE COASTAL PLAIN AWAY FROM THE IMMEDIATE COAST. THIS

INCLUDES AREAS FROM CONCORD TO FRYEBURG TO LEWISTON AND AUGUSTA.

HAVE OPTED NOT TO GO WITH A WINTER STORM WATCH WITH THIS FORECAST

ISSUANCE DUE TO UNCERTAINTY IN PRECIPITATION TYPE AND AMOUNTS.

ALSO...DESPITE THE WIDE VARIETY OF NASTY PRECIPITATION TYPES

EXPECTED...IT IS UNCLEAR THAT ACCUMULATIONS OF ANY ONE TYPE WILL

REACH INDIVIDUAL WINTER STORM WARNING CRITERIA.

The one thing to take away from the AFD is that is sucks to be on the immediate coast. lol

22.1/8

Off the board... which is how you measure "new" snow. But they also record depth every day so if you wanted to you can just see the difference.

SFVC3 had the following obs

Tuesday 12z - 7" Depth / 0" New

Wednesday 12z - 18" Depth / 12" New

Thursday 12z - 32" Depth / 17" New

So they had 29" storm total.

The change in depth was ~25"

BOX's enthusiasm for Tuesday's event is as uplifiting at Tom Brady's pathetic pass just now.

FAIRLY HIGH CONFIDENCE THAT WINTER WX ADVISORIES

WILL EVENTUALLY BE NEEDED FOR A LARGE PORTION OF THE INTERIOR FOR

COMBO OF SNOW/ICE...BUT DONT THINK SNOWFALL WILL EXCEED 6".

PRECIP MAY EVENTUALLY CHANGE TO RAIN EVEN IN NW ZONES TUE

NIGHT...BUT STEADIEST PRECIP SHOULD LIFT TO THE NORTH LATE TUE

NIGHT AS THE LOW MOVES TO THE NORTH.

20.0/7
