Should be interesting to watch Mt. Washington temperatures
True in the sense that we have an actual station to see the hourly OBS at that level instead of the 12hr balloon launches but I noticed we really max out in the -30s and when the 850s are that cold the 700mb layer is not much colder. I wonder how to explain that? Is it just because its the coldest temp that can come down at the latitude and just starts sinking to lower levels?
Here is the GFS and Euro 700mb temp for Saturday evening
That core of -35C to -40C actually doesn't make East more. Wonder why. Mountains?

Hmm. Interesting. Mid-levels at 700 mb and up are more mixed and unlikely to have huge cold swings. It looks like a polar vortex. Coldest 850 mb centered around western Quebec and the Adirondacks / northern Vermont; only northern Greenland is colder:
Temperatures stop dropping at 450 mb. Tropopause?! Might be a trait of polar masses, warm location in California keeps cooling till 250 mb, it's actually colder at upper levels than the polar air mass
Notice in the first link the 850 mb level is colder than the air immediately above or below; doesn't get colder again until about 650 mb. What cause the air to warm above 850 mb? Here's what northern New Hampshire will look like Sunday morning:
700 mb temperatures in Pennsylvania are cooler than further north in Canada; or New England

Mountains are big or tall enough to affect the flow in the Northeast. The coldest 700 mb temperatures appear to be on the west side of the polar low, from the flow

Interesting. Good stuff!! No idea why it would be warmer above 850 at that time there.. Clouds? Not in front of PC right now. Love the profile stuff! Seeing u say PA isnt warmer above makes me assume they are clearer from the surface High when NH still has upper clouds around from being near the Vortex?
Thank You. A true sole. You have a right to complain about this weekend. but someone that complains about this winter really found their answer deep inside themselves, that even during one of the warmest winters, the area is not for them & they need to move south.
Yeah, although the warmth was heavily concentrated in December, the remainder of this winter hasn't really been cold. Tolerable for me, but I want warmer, I know I belong elsewhere.

Charleston, SC reached 70F or higher on 22 out of 31 days in December. 24 days for Savannah. No winter feeling at all!
The warmth confirmed to me (for the 1000th time) that I want to move south/west.

Hmm. Check the green dewpoint line; looks saturated the whole way up in the NH profile. But 6 hours later, unsaturated above 900 mb or so:
