dendrite Posted December 22, 2011 Share Posted December 22, 2011 What are you running for temps? We have cooled pretty quick here already down to 32F Even though it's BKN/OVC here winds are light enough that we've seen some radiational cooling. I'm not sure how much of my current 37.6F is "real" right now. The Gunstock station at 1350ft is still sitting at 40.5F/34.0F with W winds gusting to 15mph. The entire Mt Wash auto road is 32F or lower now so hopefully that bodes well for here after midnight. Link to comment Share on other sites More sharing options...

We are still under clear skies here so we are radiating well, Now down to 31F, Not going to waste any qpf on rain it seems wetbulb is at 27F Link to comment Share on other sites More sharing options...

It doesn't tkae much for downdrafts with the onset of the precip to mix out that cold sfc layer. I think we'll be OK, but at least down here it may be a putrid 33-35F snow to start.As I'm about to hit send the wind has picked back up here to 8-10mph and the temp has jumped from 37.6F to 38.3F. Maybe a radiationally cooled lower 30m will help, but I've too often seen it get mixed out. Link to comment Share on other sites More sharing options...
mattlacroix4 Posted December 22, 2011 Share Posted December 22, 2011 34 here, clear, and dropping pretty quick. I want to avoid that 33 F snow as much as possible. Link to comment Share on other sites More sharing options...

powderfreak Posted December 22, 2011 Share Posted December 22, 2011 What are you running for temps? We have cooled pretty quick here already down to 32F We are now down to 33/30 at MVL so it looks like we'll be ok once precip starts. I notice MPV at 1,200ft a bit further south though is still 38/30F. Link to comment Share on other sites More sharing options...
OceanStWx Posted December 22, 2011 Share Posted December 22, 2011 For those who are interested, the evening sounding is on the way up here at GYX. We're sitting at 40 degrees at the office, and remain above freezing to about 900 mb. Lots of room for wet bulb cooling though. Link to comment Share on other sites More sharing options...

OceanStWx Posted December 22, 2011 Share Posted December 22, 2011 What level is the WBZ down to? Sadly we can't calculate that on the fly, but it does look to be fairly low just eyeballing the sounding. Link to comment Share on other sites More sharing options...

mahk_webstah Posted December 23, 2011 Share Posted December 23, 2011 dropped to 38 after getting up to 42 an hour and a half ago. See a few stars so guess we can radiate some. Link to comment Share on other sites More sharing options...

dendrite Posted December 23, 2011 Author Share Posted December 23, 2011 It's been bouncing around 37-38F for the past half hour. I'm more interested in how the 1kft+ stations are cooling. Lost River @1822' is 35/29, Enfield @ 1169' is 37/34, and Gunstock @ 1350' is 40/35. Link to comment Share on other sites More sharing options...

OceanStWx Posted December 23, 2011 Share Posted December 23, 2011 Interesting that here, despite being 38, we have puddles freezing up on the sidewalks. Seems as if the last few days of actual polar air have primed the ground surfaces to be cold. So we have sub-freezing air at the surface with 2m temps well above. Could mean a little freezing rain at onset for some places. Link to comment Share on other sites More sharing options...

Could mean a little freezing rain at onset for some places. I was noticing the same thing. The ground has finally been primed. On Tuesday there were some stubborn patches of pavement and brick in the Old Port that were still glazed late in the day, long after the air temp had climbed to near 40.

The balloon went up a little after 23z so maybe that would account for the lag in CAA? Link to comment Share on other sites More sharing options...

J.Spin Posted December 23, 2011 Share Posted December 23, 2011 I’ve got a few more temperature observations from this evening. We headed in to Stowe for a bit, and on the way in earlier this evening the temperature readings through Waterbury, Colbyville, and Waterbury Center were in the 33-34 F range on the car thermometer. On the way back though about a half hour ago it was 32 F for the whole route, and here at the house we’ve got a reading of 30.7 F. Link to comment Share on other sites More sharing options...
wxeyeNH Posted December 23, 2011 Share Posted December 23, 2011 37.3F/33.5F up here on the hill. Just got back from Plymouth NH. Temps are 30F-32F down below but warmer up here 500 feet above the surrounding areas Link to comment Share on other sites More sharing options...
