So this July feels cool, and there's been persistent troughiness, and yet we're still +1.4. What the he*l would it take (and what would it feel like!) to actually get a cool below normal July! Lol

 

Actually I'll answer my own question, back in 2009 was the last one:

So this July feels cool, and there's been persistent troughiness, and yet we're still +1.4. What the he*l would it take (and what would it feel like!) to actually get a cool below normal July! Lol

 

It seems to take an act of god to get BTV below normal sometimes these days, lol.  You can usually bet that if other stations are around 0 for a departure (normal) then BTV will be like +1 or +2 for whatever reason...or lack of radiating with pesky wind while everyone else drops off.

 

MPV with +0.5

MVL with +0.3

 

Likewise, on the flip side...there's 1V4 which is currently showing a -1.5F departure, but I'm so glad you solved that mystery the last time we had this discussion.  That'll correct upward 1-2F once they change the timing of the highs, and probably be right in there with MVL/MPV.

I think BTV was a relative warm spot that July too.

 

BTV has sort of developed into a relative warm spot with regards to departure from normals in a lot of months these days.  There are reasons they can be warmer...CAD happens east of the Greens, they have a lot of wind so they do not decouple, they can be prone to downslope warming, etc but with like 130 years of climate records you would think that would all be accounted for. 

 

I would be interested to see, of the first-order climate spots, what New England station has the highest average departure over the past 10 years.  I bet BTV would be top 3 if not the straight winner.  That sounds like stats that snowman21 could come up with.

I could speculate 2 reasons for that. One is a developing UHI that has taken place WITHIN the past 30 years. That is not present at other sites in VT, and has already been present for much longer at other climate sites, so its been reflected in the normals.

 

The second is related to global warming. In theory, and observation, it affects the low temperatures first and foremost, with whatever it is, clouds, can't radiate efficiently, etc... So this would show up more at a place that already had trouble radiating, eg: BTV (marginal radiating nights would not radiate while others still would). Water temperatures have warmed as well, and this has been noted at Lake Champlain, where it takes an act of God to get it to freeze:

 

http://www.weather.gov/btv/lakeclose

 

This was the first time in 7 years, and if you look back, the frequency of closing has definitely gone WAY down. So the warmer lake waters would keep BTV warmer.

 

 

But I don't know if these 2 things alone are significant enough to make BTV stand out that much from the rest of the sites.

So it's basically a "normal" July for you guys over there, but does it feel normal? Or does it feel cooler? I would think cooler lol. Now take another 2 degrees off of the monthly mean to get a real below normal, imagine that??

2009 was my last below average July as well, though since then only 2010 was significantly above.  Thru yesterday, this July is running +0.32, and I'm guessing the month will finish within 0.1F of my avg, probably above.  Thought 40s were in store for this morning when it was down to 56 by 9 last night, but the clouds rolled in and 5 AM was 52.  Might've dipped a few degrees in between.

 

All fourof the major CAR/GYX locations are AN, with a distinct north0-south gradient:

CAR +3.0

BGR +2.0

PWM +1.0

CON +0.7

 

PWM hasn't recorded a single HDD this month, not terribly unusual as their avg thru 7/29 is only 13.  Their max for July is 87, min 54, and 33F is a pretty modest range for an entire month, even for July, the month with the smallest variation in daily avg temps.

Only 0.06" yesterday, but temps 62/51 for coolest daily mean this month, and unless the temp pops up to about 80 (I think 70 is more likely), July will come in a tiny bit BN. Fog this morning was about as dense as it gets, at least in daytime - visibilty about from one utility pole to the next. Clearing off now in AUG.

Next up in the sequence of weather events from our location this past winter is December, and perhaps its most notable feature was the quantity of storms – a whopping 16 of them.  To put that in perspective, that averages out to more than a storm every other day, and it ties the mark with December 2007 for the most accumulating snowstorms we’ve ever recorded in one month.  What’s amazing however, was that despite the large number of storms, the month somehow managed to be significantly low with regard to total snowfall.  While the 16 storms from December 2007 produced almost 70” of snow for the month, this past December saw only 26.2”, which was a full standard deviation below the mean of 40”+.  Our area was certainly in the storm track, but the storms just weren’t delivering a lot of snow.  In terms of snowfall events, the largest storm came mid-month on the 14th, but it produced just 10.4” of snow from 0.84” liquid equivalent.  The real big player in terms of storms this past December was the one that started on the 20th.  That one had a healthy 1.75” worth of liquid, but in the snowfall department it put down a meager 0.8” because so much of the precipitation fell as ice and rain.  It was somewhat beneficial in that it generally substantiated and preserved the snow that was on the ground, which was a far better result for the snowpack than in areas farther south that got all rain, but 1.75” is a lot of liquid to waste as “non snow”.  Get that amount of liquid down as snow, and the month really could have come in near average in that department.  With its timing, that storm could have single handedly transformed the skiing to another level during the holiday period if it had been all snow.  By the end of the holiday week there was some decent powder skiing at elevation thanks to the Clipper that hit on the 26th, but conditions could have jumped up another notch if that weird event on the 29th had delivered.  That was the one that initially looked like it might provide a moderate event to Northern Vermont and the resorts there, but it ended up being focused to the south and we just ended up with a little rain.  So, there were actually a couple of misses that really contributed to the month coming in low in the snowfall department.  Anyway, the chronological list of December’s storms is below, with links to each summary:

Love these summaries, J.Spin...do you have them up on your site under one primary link yet?
