#NoPoles Posted September 14, 2021 Share Posted September 14, 2021 Last year, we had a freeze the very beginning of September and with the drought, the combo created peak foliage season that lasted around 3 or 4 days at the most. Peak was around Sept 24-26. If went fast and on the earlier side. Omni didn't get their Gondola open in time for peak. This year, no freeze yet, and things are moving so much slower. Colors are definitely on the way, though. Link to comment Share on other sites More sharing options...
backedgeapproaching Posted September 14, 2021 Share Posted September 14, 2021 Definitely noticing some subtle changing down here. Some of those purple-ish hues and a smattering of faint reds. Link to comment Share on other sites More sharing options...
alex Posted September 15, 2021 Share Posted September 15, 2021 Really hard to show changes in iPhone pictures but they're definitely changing. Plus the occasional tree that says - screw you all, I'm going for it. 4 Link to comment Share on other sites More sharing options...
powderfreak Posted September 16, 2021 Share Posted September 16, 2021 Posted in the severe thread as it evolved, but here are some obs for posterity in the NNE thread. After a cloudy morning with a few rounds of showers, not much QPF in the early cells but the one that hit in the 2-3pm hour was wild. Best wind/rain combo of the summer. A few trees down and plenty of branch/leaf debris. Always nice to have a front row seat to the mountain weather, and the velocity data suggested a pulse that moved SW to NE through the area, looked to squeeze just south of the Mansfield Chin (looks like it ran through the Nose to the south where the COOP station is). The Mansfield Summit free-air wind readings on the Nose (~4,000ft) ramped up real fast. Check out that 5 minute increase. 2:10pm it's gusting near 30mph, and then 2:15pm reading is gusting near 80mph. There's the downburst. 5 Link to comment Share on other sites More sharing options...
wxeyeNH Posted September 16, 2021 Author Share Posted September 16, 2021 .23" yesterday with weakening thunderstorms and light rain in the evening. Over the last year it has been a tale of two cities, well regions. Very wet in SNE and very dry in NNE. In my region of CNE the past year would be way, way below average if not for the 11" in July. Below is the % above or below average for the past 365 days. Link to comment Share on other sites More sharing options...

So if I get 45" that is around 9" below. Of that, 11" was in July and lots of that was quick runoff so I have to take some of that away too. I don't know how unusual 20% more or less of yearly precipitation is? Maybe some one with more knowledge of New England precip can chime in? It seems over the past several years I am constantly whining about lack of qpf. Even last winter except the big Dec 12th storm I didn't have a snowfall more than 4 or 5". 2.25" so far this month with another dry week coming up. Okay, rant ova!

To me it’s more about the sensible consequences of weather. If it rains 3” or 6” in a month it’s fairly inconsequential from an every day perspective. Now when vegetation starts wilting and wells are running dry, it’s another story! in terms of standard deviations, I’m not sure how much variability there is year to year, but if I were to guess I’d imagine 80% of normal is not particularly unusual. But that’s completely not data based, I have no idea! Link to comment Share on other sites More sharing options...

That’s all built into summer climo. You’ve (we’ve) always had short duration intense convective rains in the summer since the dawn of time. It counts just as much. No where in the annual precip of New England does it say short duration heavy rains need to be removed… the annual precipitation totals build plenty of that in. I’ve always found that reasoning odd but it’s not just you, it does come up around here in the forums a lot in summer… when folks are like I got X inches of rain this past month but most of it doesn’t really count because it fell quickly and ran off. I know its a reference to not feeling like the vegetation got watered, but the vegetation has been dealing with convective rains for centuries here.

Looks like I'm at 59.67" which is prob a bit above average and there is a little sliver of green near my station which seems about right too. Mitch is over 70". No one is within 10" precip wise. Obviously its been a little wetter overall in the southern part of the state as the map illustrates. Link to comment Share on other sites More sharing options...

Is it snowier or not? I’ll chime in and say I’m confident Whiteface does not average the same as Stowe. They cash in a few times with decent lake effect but Stowe is almost always getting snow as well when they do. Stowe is better with the uplsope and is positioned better for many of the coastal storms. I think an interesting question is what do the core high peaks around Mount Marcy above 4-5000’ average. I think that could be much closer as I think that area does a bit better than the whiteface basin. Link to comment Share on other sites More sharing options...
PhineasC Posted September 19, 2021 Share Posted September 19, 2021 I only have two summers under my belt, but this one certainly felt a lot different to me than last summer. It has seemed to be pretty wet and there were even some spells of what seemed like upslope rain from time to time where it would be raining pretty well at my place and just drizzle down in Gorham. I haven't checked the CoCoRaHS numbers too closely but I'm sure we are running close enough to average. My well has been in great shape too. It has seemed a lot less hot and humid than last summer too. Never really even got near 90 at my spot. Hit upper 80s briefly one time. Link to comment Share on other sites More sharing options...

Is it snowier or not? I'm trying not to be a homer, and I have no real direct observations between the two. My first season pass was to Whiteface/Gore back in high school, moved to the VT side during college and never went back for skiing. It feels snowier in VT, though the 'Dacks are cold and hold snowpack very well. The weird posit is that there is a sweet spot elevation zone in NNE mountains that the true high peaks may be too exposed to capitalize? The Adirondacks and Whites have far more above treeline terrain than the minor amount in the Greens on Mansfield. More wind, turbulence that causing less than ideal crystals too? Higher snowfall in the areas surrounding the big terrain, definitely less mixed. I do think the Northern Greens are better in NW flow upslope (those conditions exist mostly during strong NE tracking storms) and are further east for coastal synoptic events. That's why this area over through Alex and Phin's area is so snowy. The best overlap of orographic snows and synoptic snows. Some years feature differing amounts of SE vs NW flow events, more mesoscale precip versus larger scale synoptic SE-E flow off the ocean. The overlapping zones do the best statistically over the course of the winter season. 2 Link to comment Share on other sites More sharing options...
powderfreak Posted September 19, 2021 Share Posted September 19, 2021 Pretty cool we are getting towards that time of the year… warm lake waters and cold air above them: NEAR TERM /THROUGH MONDAY/... As of 710 AM EDT Sunday...Only minor changes to the forecast based on latest observations. Increased cloud cover locally over Burlington and south into Addison County as a lake band has developed downstream of Lake Champlain this morning. Based on NAM3 sounding profiles, temperatures aloft at ~1500ft are around 10C and latest lake ob shows water temps of 68F. This give a delta around 18 degree supporting the development of this cloud. As daytime heating commences the temperature difference should lessen therefore expect this cloud to dissipate within a couple hours. Link to comment Share on other sites More sharing options...
Patriot21 Posted September 19, 2021 Share Posted September 19, 2021 Was cooler this morning than I expected it was gonna be.

For what it’s worth hermit lake plot has average 200+ inches I think at like 3900’ over the past 3-4 seasons and I don’t think they’ve even had 1 average winter so who knows up at 5000+. Like you said wind could be a huge factor. I think they had 175 or so counting October and November last year in a pretty abysmal winter for that zone. The early and late season snow really tallies up there. April 2020 was huge there I think. Link to comment Share on other sites More sharing options...
wxeyeNH Posted September 19, 2021 Author Share Posted September 19, 2021 Fantastic day today. So far this fall my low has only been 48F. A year ago right now I had several nights of mid 30's which really got the colors going. Peak foliage was occurring in Alex's area on Sept 27th. It was a very quick, vibrant peak. Here is a drone video of Bretton Woods and Alex's Moose Lodge on that day. 2 1 Link to comment Share on other sites More sharing options...
