Kind of an interesting micro-physical connection with the bigger picture…

The soil moisture from Ontario to New England is up thanks to Irene and what not over the past several weeks. I think this moisture is off-setting some of this dry air transport – similarly this may have taken place back in September with that cool snap. It is interesting because the DPs rose in many areas shortly after sunset, and then the temp and DP met in the upper 30s to around 40 in most spots (with a few exceptions here and there).

Here’s the obs from FIT this morning:

061452 CLR 10 56 26 3311G18 258

061352 CLR 10 52 29 3210 260

061252 CLR 10 48 32 VR06 263

061152 CLR 10 43 31 2703 261 001 43 36

061052 CLR 10 37 33 0000 258

060952 CLR 10 40 31 3103 255

Noticing firstly a rather explosive temperature rise… Should be 60-63F there this afternoon, which would mean MOS types are handling nicely – different matter but that is interesting that any transition season MOS output would do well assessing a high temperature; there’s usually a lag in performance there. But, notice the DPs are down into the mid 20s now that we are mixing out the boundary layer. So, that means that the moisture in the boundary layer had to have come from below – ie, the Earth/soil.

It seems pretty intuitively correct to me that if the leading late summer and autumn so far were more arid, then this and the September CAA events would have been drier, and we would have realized more frost and/or freeze conditions more proficiently. It will be interesting tonight because the wind trajectories are even more “calm like”, so there is likely to be more decoupling – a combination of that and an ample soil moisture source from beneath could cause for some pretty good frost types, perhaps even some ground fog-related rhyme in some of the typically colder hollows.

That all said, check out this 24-hour recovery at FIT (and this is obvious true throughout the SNE domain)!

NAM MOS from 06z:

HR 18 21 00 03 06 09 12 15 18 21 00 03 06 09 12 15 18 21 00 06 12

N/X 37 63 46 79 57

Yeah it's possible that soil moisture may keep dews up by a couple of degrees. I mean at least physically it makes some sense, although I'm not sold that it's a significant factor..but it might keep dews up a couple of ticks.

Getting back to the increase of dews near sunset, many times I notice dews spike up a bit as we begin to radiate and lose the mixing of drier dews from aloft. However, this only goes on for a short time because eventually we even out and in fact may drop dews a bit during the overnight as we condense out some of the moisture. I always found this phenomenon pretty cool.

I usually don't either being on a hillside, but we dropped to 31.8°F in Stafford Springs. I wonder what it was down by the river. They are usually at least a couple of degrees colder than I am on mornings like this. There was frost down there a few weeks ago while I was 38°.

Up to 54 now....I guess we'll see what tomorrow brings before this weekends torch. :thumbsdown:

You must radiate well for some reason even being on a hill..maybe there's a larger hill on one or either side of you?

i only got down to 40.1 for the low and the loss..but it's the 2nd highest hill in Tolland

Kind of...I'm on the south slope and there's another 150' above me and 150-200' below me. Of course I'm flanked to the east by the rise of land that leads up to Union, another 600' up, so yeah, perhaps that cool air makes it by my place as it's settles in the valley.

Speaking of the valley, awesome views this morning as the valleys were filled with fog and the hills looked like islands...not sure if you saw that down your way. Knowing where you live, I suspect it was probably a lot cooler down by Rte 74 and even more so in the center of town.

It was..that is where I saw all of the frost..Down in center of town by the green all the way down past Subway...it really radiates in that area. They were down to 30-31

The fog on the CT River was awesome. I saw some in Farmington on the ramp from Route 9 north to 84 looking east past downtown.

I have a nice view down the Willimantic River valley as I come into work...It reminded me of when I was in college up at Lyndon. Not sure if you've even been there, but the school is on top of a hill. Many cold fall mornings in September the valley would be filled with fog and Burke and the range would look like islands. Coming down the mountain into the CT River Valley I could see fog along the CT River.

Note to Kevin, and Ryan,

I think it was both of you who warned me to keep away from the OT forum at the gtg in Worcester. I think the topic at that time had something to do with Vim Toot bashing. Unfortunately I did not heed your warnings, and am now suffering the consequences.

For that reason, I give you, or anyone else that shows up at the next gtg permission to take me out in the alley and beat the crap out of me. I will supply the (3) Louisville Sluggers to do the deed.

:facepalm:

Signed,

~ Cold Miser ~

Keeping things on topic.

The Connecticut valley up this way is notorious for morning fog--summer and particularly in the fall. I live in the hills outside the valley but work deep down in it--so, many mornings I start the day off bright and sunny up at the house only to drive down into the fog. T'was that way this morning.

temp this morning was 40.8, no frost...was chatting with a co-worker who lives in Swansea and she had a good frost...said it took a bit of time to scrape her windshield this morning...

I didn't realize Swansea radiated that well

I guess it makes sense

My family room got down to 60F. Trying to avoid running the heat

53F attm
