I'd love to have a time machine to transport me back in time to experience that storm. And The Hessian Storm,

Gah it’s so refreshing out.  

Low of 51F this morning and currently 69/51.  

Finally some solid upper 40s to low 50s dews.

[powderfreak]

Breathe it in.

[weatherwiz]

gotta love the differences between the 6z/12z 3km NAM

I actually can't stand the 3km NAM...I think it's a POS model. You would think the increased resolution would make it pretty solid but I think it's trash. IDK...maybe some scores out there will prove me wrong but it's trash.

[Cyclone-68]

I miss hearing about the “sunrise surprise”

[Baroclinic Zone]

Little model disparity on QPF output into Saturday for modeled rains.  Here are the 12z GFS, 12km NAM, and 3km NAM. 

[Baroclinic Zone]

Even with low dews, we torch.  Up to 86F

[alex]

Feels fallish here. 72 after a low of 44.8

Damn its so comfortable here today,no sun at all and low dews.  My house needed it.  No power, no shirt, no shoes, no problem

Ditto!

Euro, Ukie, GGEM are virtuall dry for here.  GFS is on an island.

Droughtstein really digging his heels in now. Most of us are in mod drought now

75/52 

Mostly sunny.  These are the days @PhineasC saw in the brochure.

Yep 73/52 in Randolph. Sweet.

Was sitting on the Statehouse lawn having lunch with a colleague and the breeze felt coolish.  I had put my chair in the shade and thought maybe I should have out it in the sun for a brief minute.

That low temp seems way out of alignment with other stations around it. It was closer to 54 degrees unless you were in a unique cold pocket.

Your going to need a crash course on the microclimates up there..  Alex is king radiator.

That's true. A 10-12 degrees difference last night from the CoCoRaHS sites seems hard to believe, though. That's a large variance. I am not doubting anyone's readings or integrity.

I was at 54 degrees for the low last night at 1,500 ft, so a 10 degree drop from that is impressive.

Whitefield NH, which is a rad pit, was 44F last night.  Guess your on some type of hill which isnt going to radiate much. 1500' isnt created equal in NNE. Alex at 1500' will radiate like crazy being in an elevated valley, you at 1500' maybe not, guess we will se moving forward.

[ORH_wxman]

Yeah the terrain is so steep in the whites there that you can have massive radiational cooling differences over small distances. 

[klw]

For those of you concerned by the cool morning, rest assured that the Euro and GFS are in agreement of no snow the next 10 days.

 

 

While I have not tracked the GFS performance in this regard, Euro was dead on re July snowfall.  It is on a roll!

It'll be interesting to keep comparing stats as we go into fall and winter to see which setups favor which locations for temp drops day to day. My weather station runs pretty close to accurate at least against the CoCoRaHS station up the road.

Not questioning anyone's readings, I am new to the area and couldn't imagine such a large variance over like 15 miles at the same elevation. That just doesn't happen in southern areas.

Yeah it all depends on the relative location to the terrain around you. If you are on a local hill at 1500, it won’t radiate nearly as well as a local depression at 1500. Around there, you have such steep hills and mountains, that the differences get magnified.

You prob radiate decent being generally between two large mountains but not as well as down the road along rt 2 in a relative depression.

Doesn't always take large differences in elevation.  On still clear Fort Kent winter mornings, my commute from the back settlement at 970' led east and then due north so I could see the cedar mill and its cone burner across the river in Clair, NB.  If there was a smoke layer about 50 yards above that burner, I knew it would be 10-15F colder at our riverside office (about 540') than it had been at home.

Then there is the wind to consider.  When we lived in Peacham, the coldest night we had was right after a frontal passage and the wind was up.  It prevented the cold air just sinking below us like it would on calm nights.  We quickly got to about to -28.  On a calm morning, we would often be 7 to 10f warmer than just half mile away where the elevation flattened out about 300' lower than our house.

So many variables.

edit: and so many typos

[wx2fish]

Those local difference really show up on the winter with a good snowpack. I've seen the First Lake coop run 10-15+ lower than johnsnhweather. Hes less than a mile away and about 150' higher.

Looks like his house is for sale too, which is too bad. Quite the weenie spot and a nice house. 

[ma blizzard]

Even in the "tropics" of SNE I've seen some pretty wild temp variance with deep snowpack in place. Growing up, my area was a pit relative to the surrounding terrain. I recall instances where I could be as much 10 degrees colder than other backyard sites just a couple miles away and ~150'-200' ft higher up. Not a common occurrence by any stretch, but when it would go calm imby it would really tank, while a little higher up it wasn't able to decouple.

Any chance you or anyone could provide a link to that Northeast dew map?  I’ve been on that site, but can’t figure out how to get that Northeast view. I used to use USair.net for dews, but it doesn’t work for me any longer. 

[weatherwiz]

I think we may break the record for 90F days in CT. TORCH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
