It only needs to shift a bit southeast for New England to look a lot better. You’d get something like a 2007-2008 pattern or maybe 2016-2017.

Yeah nobody uses sigma so it sounds weird but if the met community started embracing it, then it would eventually sound normal. Problem is the percentage anomalies are just way too popular to abandon even though they aren’t super useful. They don’t tell us much without peaking at the baseline and variance (which standard deviation has covered).

Get the AK ridge more poleward and it fixes a lot of issues. Esp up here.

This is the time of year we all get fired up or depressed over seasonal model outputs. It will all be forgotten in 6 weeks.

Yeah it would be more useful if the community embraced standard devs. Like “this looks like roughly a 1 sigma above normal snowfall winter for BOS to BTV”....one sigma for BOS is prob like 150% of normal while in Stowe it might be 115%.

Only if you go by percentage. Standard deviation takes care of this problem.

The H5 anomaly is pretty hideous.

That is a crazy trough out west next week. Really low snow levels with that thing for October standards.

On a regional scale, this stuff doesn't matter that much. The temporal and spacial variability is going to mostly drown out a climate signal when we're talking monthly departures. You might adjust a forecast to hedge slightly warmer than if there was no underlying climate signal, but it will be dwarfed by the hemispheric pattern. That's why we were able to break the February 1934 monthly cold records at many sites in New England back in 2015 despite 8 decades of warming. Maybe instead of predicting a -3 month based on a 1970s analog, you forecast a -2 month or something like that.

You can see how cold the late 1970s through early 1990s were in autumn on the first freeze/frost data at ORH. Like the 1980s might be the coldest period for autumn on their timeline. That matches some of the discussions we’ve had on here....both anecdotally and other data.

Yes it is. For the airport alone, need to start the year at 1948. Though I'm not sure how different the numbers would be for frost/freeze. The older site radiated much better which probably produced several freezes when the airport wouldn't have gotten them. The older site actually had a slight cold bias vs airport on low temps. The high temp differences were more noticeable though.

We got plenty of hydrology lessons examining the movement of the cups and the runoff onto the carpet.

It drops off very quickly south of Foster RI....the CAD zone really goes from like somewhere between 128/495 in E MA and then into N of RI west of 295 and then down to about Foster and near you. Once you get into like Plainfield or just south of them over to west greenwich RI, it vaporizes. The gradient is prob really noticeable just south of you....SE CT as we all know just cannot hold any cold air at the sfc.

I’m usually happy to just grab first measurable in November in the interior. Anything more is pure gravy. Even the first half of December can often be kind of annoying waiting for legit advisory or warning snow threats....but it’s not uncommon even in the good winters that aren’t purely backloaded. 2008-2009 and 1993-1994 come mind. 2010-2011 too.

Top of the presidentials might be frosted white tomorrow morning. Some snow up there today at the very top.

Lol....I think Ray would be happier in an 8" storm that he jacks than an 18" storm where he doesn't.

108 consecutive days in 1970-1971 is the official record at ORH....but 2000-2001 may have challenged or defeated that number. I believe 12/20/00 to early April gets us really close. It all depends on when the official number would have gone to a trace. Too bad we didn't have snow depth records there anymore. May have fallen just short since up at the airport it is not as sheltered and starts to melt out quicker in spring with the sun angle. For total days with at least 1" of depth (not consecutive), ORH's record is 113 also in 1970-1971....the xmACIS site lists 1907-1908 and 1906-1907 as way higher but there is something wrong with the data on thiose years. Didn't pass the smell test as soon as I saw 1906-1907 having 155 days....they didn't even have that much snow that year. Ditto 1907-1908. Sure enough, when I checked the dailies, they looked way off. 1907-1908 actually had 39 days when I counted and then 1906-1907 had an early 7" snow pack unchanged for over a week in November with several days in the 60s plus some rain. It's like they forgot to change the 7 to zero after a day or two. Once I saw that, i stopped scanning.

75 days officially in 1904. They came close in 2015 but it wouldn't have been official since they don't keep snow depth anymore. But nearby Hingham to the south had 71 days in 2015. edit: I assume you mean consecutive days?

He needs a few '88-'89s in a row and throw in another couple 2/1/21 screwjies for his BY and he'll be chomping at the bit for a 3-6" event like Ginxy scans the models at 3am for windex events.

'94 did have a thaw in late February too before another reload. Yeah the coast got the best anomalies. Interior got hammered too, but not the anomaly that the coastal areas got. But the interior did very well in storms like 1/3-4 and 1/12....and then later on they did well in March.

Brady is obviously a pretty special circumstance...played for 20 years in NE and is the best of all time.

As Bill Parcells used to always tell his star players, "the fans don't root for you, they root for the laundry"

I think there were actually 3 cutters, but they became less ridiculous with each one. The first cutter was the worst I've ever seen.

Yeah that look would be cold here and probably pretty active. Almost looks like a ‘93-94 but shifted a little east with the PV anomaly.
