There’s your micro +1C layer. That’s dangerously close to a thump though.

Is there somewhere on AmericanWX or somewhere online to learn how to read these? I see them all the time and have no idea how to break them down.

Seeing some 35-37 readings near Hubby, Gardner, Westminster.  That's a nice drop.

On the left going up in white you have the pressure levels…sfc-1000mb up to 100mb. Horizontal axis is temp/dew in degC…temp is red…dew green. The temp lines slant up and to the right 45°. There’s a little nose of air a bit above 850mb that is higher than 0C.

This thing has a 31.9 straight rain "just realized my calibration musta been .02 degrees too cold all along?" look about it.

Wouldn't be the first time the NAM sold big QPF from a little critter.  heh we'll see

Very helpful. Thank you

Wunderground keeps upping the snow totals. Now to 5”

[Damage In Tolland]

NE winds blowing good now steady drop continues. Hopefully enough 

[J Paul Gordon]

35F/30 here in Clinton and going down.

 

[Masswx]

Rainer here enjoy north 

[MuddyWx]

latest hrrr looks pretty good imby.. so tough. could see 1", could see 6"

[Modfan2]

40F here in the valley in E CT and dropping. Decent breeze out of NNW

[wxeyeNH]

39.7/27.7F

We were far enough north that we had some bright sun this morning into mid day.  The temperature maxed out at 49F.  Over the past couple of hours the temperature has been falling as well as the dew's.  Especially the past hour.  The point and click in our area is around 1" of snow.  No advisories are up.  The trend is your friend and I could see my area of the Lakes Region getting 2-4", maybe up to 5 or 6" if we can get the precip up here.  It will be interesting to watch.

[HIPPYVALLEY]

Interestingly, temperatures are up a degree or two around here since the light rain started. Even up at the elevations. Latent heat release?

[Damage In Tolland]

ORH down to 34

[metagraphica]

Down to 41 off a high of 43.  Rain.

Already down to 38F; might be good sign for your area and higher elevations to my north

[met_fan]

Perfectly happy to mostly sit this one out here

[HoarfrostHubb]

32F here.  Raw and breezy.

Looks like HRRR was right a few hours back.  Nice drop.

I’m keeping expectations low. Still need 5-6 degrees so gonna be a few hours at least 

[ORH_wxman]

Near midnight and just beyond is when you see the sounding try and go nuts....if we get big omega, then we can prob flip to paste....otherwise lot of sleet and mangled flakes probably....but you can see here what the HRRR is tryong to do (other guidance was similar)....you start blasting the DGZ with deep lift, then you can really latently cool the column efficiently. 

 

And almost every single sounding has that warm layer really thin too. So you know this could be a rate-dependent type of system.

Blueballs snow. Blue spring Sierra cement  No fun pushing through that for 6 hrs, oh wait it was a fukin blast. 

[HoarfrostHubb]

And like I figured…ORH schools are closed.  

[CT Valley Snowman]

40 here.  Ice won't be an issue.  Now I'm hoping to see some sleet.
