That's the worst... if it rains in these patterns you want like an inch, to evap cool. The worst is like 0.01-0.05" to wet the ground but not enough to cool the air...the dew rises like 5-7F immediately after.

The heat wave finished off the snow at Stowe for good. This was yesterday (photo from a friend), last pile left. Made it till July 4th in past years but record breaking heat did it in. Shut 'em down. No more snow on Mansfield.

Only had 0.05" last night and like 7 miles north had over an inch. Multiple reports in N/NE VT of over 2" of rain last night. Must've really lit up overnight.

A nice synoptic soaker tonight, almost like a winter storm radar.

The crazy thing is the other PWS around him at Bretton Woods are just like a few hundred feet higher and often look to be like 10F warmer at night. It is nuts how little things matter in radiating. They moved the MVL ASOS two summers ago to a spot that is 30 feet lower in elevation and about the bottom of the airfield (730ft to 700ft)... I think it gained MVL another couple degrees of rad cooling just by re-siting it next to the stream and field bottom that winds through the airport. 30 feet won't really impact the daytime temps, but at night, going 30 feet lower in an already radiating field can get you an extra couple degrees. SLK had another freeze at 31F and the Adirondacks are a good example of the temp ranges at night. You have some spots that can't get lower than 45F at 2,000ft but at 1,500ft SLK can dip below freezing because it literally is the lowest point around. Same with Alex by the river...in NNE its sort of like if you can flood from a stream or river, you probably radiate like mad because you are literally the bottom of the drainage as the cold air settles in at night.

The number of Top 10, Chamber of Commerce type days this spring and early summer is incredible. After April's disaster of cold and snow/mixed events (but nothing large, just a lot of 1-3" stuff, even ZR/IP), May flipped a switch with large diurnal ranges and copious sunshine. June has continued that. The majority of days in June have have minimums under 45F and 5 or 6 days have featured 30s in the morning. Tonight should be another seeing as temps stayed in the 60s (low starting point) and dew points that got into the 30s late this afternoon. The day's shallow cumulous have dried up with the lack of insolation and the temperatures are starting to drop fast. Here's a shot from today's hike...It really has been a great stretch of weather for the last month or two.

Frost threat again tonight. Was at the gym where TWC was on and this started scrolling on the screen about frost tonight. Some spots could get their 3rd frost of June...a few COOPs have had freezes. Crazy month. Including the cities of Star Lake, Saranac Lake, Tupper Lake, Dannemora, Lake Placid, Newport, Island Pond, Johnson, Stowe, St. Johnsbury, Montpelier, Bradford, Randolph, Enosburg Falls, Richford, Underhill, Bristol, and Ripton 354 PM EDT Mon Jun 25 2018 ...Localized Areas Of Frost Possible Tonight... The potential for localized areas of frost will exist tonight across the northern Adirondacks of New York and parts of north central and northeast Vermont. Temperatures will fall into the upper 30s across these areas after midnight tonight and some localized areas will get into the lower to mid 30s just before sunrise on Tuesday...especially those locations in or near sheltered valleys. If you live in these areas and have any vegetation that is sensitive to frost and cold you should to take the necessary steps to protect them tonight through early Tuesday morning.

September vibe out there today. 66/42 at 2pm in the valley with puffy Cu over the peaks. Nothing like breezy NW flow, low dews and sunshine with temps struggling into the upper 60s. Was an amazing hike on the big hill today.

Dropped 11 degrees last hour at the airport...like a heat vacuum in the valley fields when the sun goes down behind the mountains.

And humans.

77F this afternoon with low dews and full sun.... so many of these amazing days this June. And even May was one of the nicest months in NNE that you can get. We may pay the piper at some point after 2 months of Top 10 days. Monthly mean is 73/44 and -2.1, almost a 30-degree diurnal range in the means. But not quite as nice of weather as May with a 31-degree diurnal range in the means. That range is important in that it shows a lot of clear, sunny, dry air mass type weather. The wet and humid months usually only have more like a 25F diurnal swing in the means.

Yeah woke up freezing in the house with all windows open and saw it hit 43F for a low. Beautiful day out there right now. Tons of cool mornings this month so far.

Trying to cool off but still a mild evening. Temps up this way in the mountain valleys range from upper 50s to low 60s. At least it's mild enough to keep the windows and doors open for now.

Saw J.Spin's orographic spot picked up 2.54" yesterday...nice watering there. I had 1.46" in the stratus this morning.

Yeah cold front moving through finally. BTV gusted to 46mph with the FROPA at 10:30pm. 2.28" on the day for BTV, too. I think that's like 60% of normal rain for June falling today.

I'm seeing some PWS between BTV and MPV approaching 3" now. Still raining out, I'm not going to check but I'd assume around 1.5" here given local PWS in the 1.4-1.7" range. Good moisture dump that was well needed. Tropical evening, no windows and doors slamming shut from radiational cooling this evening. 72/72 +RN type obs.

Crazy story Hippy, glad all ended well.

Turning into quite the wet day. After a couple hours of storms dropping an inch it's started pouring again this evening. Tropical rains with this humidity. Fairly widespread 1-2" amounts now from BTV through here and eastward. Even some stations on the west side of Mansfield over 2" now.

Well needed drink of rain today... like 2-3 hours of thunder it seemed. 0.98" of rain at my house. MVL ASOS picked up 1.08". The grass and vegetation needed that.

I love the micro-scale differences the topography allows for in the mountains, especially on these evenings when it's a struggle to get the nocturnal inversion going. Only the lowest spots between higher terrain (along the river) are able to go calm and radiate efficiently.

Big difference tonight if you can go calm or not... feels real good out there tonight. Comfortable air moving into the home after today's sunlight really heated up the interior. The ASOS here has gone calm causing a sharp drop into the mid-60s, while BTV and MPV remain well mixed with temps in the 70s. Even BML and HIE are still mixed. It'll probably be an up and down night with large differences even on the micro-scale with such a weak surface inversion. Places like BTV won't get past the low-70s tonight. That's a summery night.

Now that's good livin'.

Slight risk tomorrow for NW MA, VT, NH, W.ME.

Yeah I hiked and it wasn't too bad but I agree I wouldn't call today COC. Low-80s with low dews is probably the limit. I think we got at least to 87F up here. My vantage point though will be much different than say someone in CT...but an afternoon of 82/45 in July would be pretty damn nice.

Low 80s with low humidity is most certainly chamber weather in June/July/August. Once into mid-80s, even with dews like today, it's more summer-like heat. But a bunch of 82s at the ASOS with low humidity, absolutely. In mid summer, anything with dews in the 40s and 50s is pretty much Chamber weather, lol. If its really enjoyable to be outside to do activities without sweating profusely, that's pretty much the driving force behind the Chamber of Commerce weather moniker.
