Oh man, what a spot there! Mountains or beach, best choice to have to make.

The 6-week seesaw continues from anomalous cold to hot to cold to hot. Now another cold shot pushing climo a bit. If it ends up 3rd or 4th coldest June 13th since 1880s in BTV, that’s note-worthy. Short Term...Saturday is going to be a chilly day. Just how chilly you ask? Well, not record setting but it could be the 3rd of 4th coolest June 13th on record. A strong upper level trough will situate over the North Country on Saturday with 850 mb temperatures dropping below zero over much of the region during the morning and early afternoon hours. In addition to this colder air, clouds will be entrenched across the region with little sunshine expected throughout the day. Highs will struggle to climb into the mid 50s to near 60 degrees with summits seeing highs in the low to upper 30s. If you do plan to hike, make sure to have a warm layer as many people don`t expect temperatures in the 30s at summit level in June.

Saturday night looking crisp... fairly widespread upper 30s and lower 40s.

FB reminded me that 4 years ago today we were heading up the Toll Road to check on something at the top and were seeing some June snow showers. I do think this was the latest I've seen or documented flakes flying on the mountain.

Man tomorrow stands out like a sore thumb. It’s going to be like one random day of Halloween climo mixed into mid-June.

Actually looks like maybe an outside shot at graupel or flurries for the picnic tables on Saturday. NW flow with very cold sub-freezing 850mb temps pushing in... 00z NAM

I gotta imagine that gets warmer. Seems excessively cold for mid-June. A wild ride the last month... record heat, plenty of hot days, and then also days with 30s in the morning and highs in 50s. Saturday afternoon’s temps will be 10-15 degrees less than this afternoon’s dew point, lol. Saturday Partly sunny. Highs in the upper 50s. Northwest winds around 10 mph.

Looking at the models for this weekend, holy crap is Saturday looking cold. 18z temps on Saturday afternoon on the NAM and GFS are low 50s... that’s uninstall and turn on the heat type of day. It doesn’t even look like rain, just cold.

I just don’t get the obsession every single summer. Summer climo is long dry stretches and when it does rain it’s convective short duration downpours. It’s not going to change.

2.26” at TAN ASOS... that’s a solid drenching.

That’s like half a month’s normal rainfall in an afternoon at TAN.

Damn, TAN is just ripping off 3/4 mile visibility obs in +RN. It takes some heavy rain to stay down under a mile visibility on an ASOS.

Bob's racking up that water. Nice. Much drier air moving in up north here.... dews back into the 50s and very noticeable from the near 70F dews early afternoon.

It's crazy how the western mountains and adjacent valleys do weather. A guy who worked for me two winters ago now lives at the base of Aspen Highlands, he was like 80F the day prior and then it was snowing that next evening. He only had a sloppy 1-2" from his pics at that elevation but they got like a foot like 1,000ft up the hill. Then the sun comes out and it goes to 70F. The dry air has to help, the wet bulb never seems to go above like 50-60F, even if it's in the 80s for surface temperature. If it rains it gets real cold in a hurry, and then up at like 10,000ft it seems like the wet bulbs are always only in the 30s/40s at the hottest climo period in mid-summer. I do think those dry dew points and low wet bulbs are whey the western mountains have that climate where it can be "beautiful or snowing"... sunny and 40s for skiing but the moment it tries to precipitate it's immediate like 28F and snowing. Unlike here in the East where we are sunny and 40s ahead of a system we can be screwed very fast. They have none of the "antecedent air mass" concerns.... it could even be 50s in March on the slopes when the sun comes out but even so if it precipitates it'll never rain, always snow.

Sort of sounds like any model... if you can recognize the times they are wrong, they can be pretty damn good outside of those times.

Yeah we've had some really good timing for summer days. Got some good downpours early this morning to water the vegetation and then break out into sunshine/dews/temps. I think It's about to come to an end though... mountain just disappeared from sight behind a rain curtain, looks like it's pouring as the FROPA comes through.

81/69 right now at the ASOS... certainly feels like summer out there. Wasn't paying attention but seems like we are getting more sun with these dews than expected. Looks like front is through BTV as they just went westerly and dews dropped an immediate 6 degrees.

These northern Vermont dew points right now would make DIT proud. This is by far the highest dews of the season at midday noon.

Picked up just over a third of an inch of rain this morning in a couple good showers. Lots of low clouds now. But wow on the humidity! Dew point up to 69F now at MVL ASOS. That rain jacked up the low level moisture.

Great evening up north. Good to be home. Every time we travel, we get home and are like, yup this is the spot. Taken from a field about a mile walk out the back door. 64/50

Ah f*ck! You are right, the angle of the skew-t slope is greater than the slope of the dew. I had the valley mixing with widening gap trick me into it. I tried to give DIT the benefit of the doubt. I should remember not to do that. Salesman vs science.

With that said, ORH at 1,000ft never had a dew point hit even 60F this afternoon. ORH stayed in the 50s for dews all day long. Must've been a strong dew front between ORH and TOL.

Its negligible but yeah. In the middle of the afternoon with good mixing, especially if comparing a forested hill to a field in a valley. Here's a sounding this afternoon from the CT Valley. The dew point increases about a degree or so with height. But the temperature difference is crazy. Look at that extremely long tail on the temperature plot... that is an insane lapse rate in the lowest 1,000ft. There's a reason DIT talks dews and not temperatures in the hills of NE CT. The temps cool off a lot with any height outside the CT Valley.

Wow. ORH’s dews are in the 50s at 1000ft. It is quite a difference from NE CT at times. We left earlier and it definitely started feeling more humid than the past few days.

I’m not too different... WWBB I think in 2003-04 winter was my first winter on the boards when I was in the UVM dorms.
