Down to 30 at Berkeley and 31 in the valleys of Sussex Co, meanwhile it's warmer at the summit of High Point than it is in my backyard in Queens!

41 at my house, 44 at High Point, and a mild 50 at LGA.

* I was jogging earlier tonight and I was running down a hill and it got noticeably colder as I went down the hill, showing how RC is alive and well even within the 5 boroughs.

A low of 28.2

[jjvesnow]

i hit 29.5 here. Its been in the 20's everynight for the last 3 nights.

Every morning this week i had lows below 25 degrees, but to me its fools cold because of no elevation and being in a valley, i rather have milder temps at nite with elevation so when the snowstorms come i get the accumulation instead of the fools cold only when its clear out.

I'm opposite. I'm a big fan of radiational cooling, I'd rather be in a really deep valley and get the coldest overnight temps as opposed to the snow.

Looks like Pequest got the coldest, down to 27 last night.

4am temps:

Cooling off in the South Jersey Pine Barrens region with a 28 Degrees reading at Hamilton in Atlantic County, yet most of Sussex County is already into the upper 20's as well. Are 20 degree readings normal for this time of year of Sussex County, or are we a bit chillier than normal for early November?

Wind has died down here and it looks like my coldest night of the season is possible. Currently 32.7 degrees, 30 degrees is my low this season.

you are foregetting that that fools cold can also help keep snowpack longer in certain situations

29.4 degrees my morning low.

Yes, true RG.

I even get the opposite effect, in marginal cold, my area does not drop below freezing at night. So the ice and snow don't re-freeze.

Interesting event this morning if you're into radiational cooling. VERY shallow inversion layer observed this morning across the western half of Vermont. Coming into the office this morning, I left my apartment in the base of the Winooski Valley (~300 feet) with a temp of 23F. Drove westward up in elevation out of the Winooski Valley into Williston where the elevation is 500 feet, and the temp skyrocketed to 39F! Continued onward to where the office is in South Burlington (~350 feet), and the temp sunk back down to around 33F even though the Champlain Valley is much less prone to radiational cooling because of the lake and the terrain's various channelling influences increasing mixing.

Needless to say, when the sun came up, the inversion layer mixed out RAPIDLY due to its shallowness and at the office we were up to 45F by 9AM.

This map of our CWA shows it pretty well this morning:



You can clearly see the mountain valleys compared to the higher elevations. I put an oval around the Winooski Valley where the light blue colors (20's) are surrounded by the upper 30's in the higher elevations (21F vs. 37F). The warming provided by the lake is noticeable as well (39F).

Weatherbowl - I was definitely in the low 30's at my house this morning, we had some people over last night including some upstate relatives, and we wound up hanging out in the yard for an hour or so around 2am and it was by far the coldest night of the season. I was saying to my relatives that I WISH I had my weather station up and running.

Rad cooling helps preserve snow in winter in the burbs. It's also the way the temp drops on most of the earths land masses. It's the big cities that have taken us away from rad cooling.

Not sure what i was the last 2 mornings but my therm hasn't been lower than 28 and that was when we had snow on the ground. It may have tied it but hasn't been lower since. I had patches of snow until Saturday. Still have piles around though.

13 at Walpack this morning. Ave low this time of year is probably about 32.

I've barely made it into the 20's this season as my lowest temp so far is 29.7. I've only been at or below freezing 3x.

Per my wx station, I've been below freezing 5 times since the end of Oct with the lowest being 26.4F this past weekend. Second lowest was 27.0F Halloween morning. Always seems to be a fairly big spread in our rad cooling temps.
