This is lucky tho ... Spring enthusiasts will be sticking their head in the sand come Tuesday until further notice. 

I'd almost prefer not going thru these unworldly early warm-ups, particularly when we have a high confidence recession of temperatures and seasonality forecast to tsunamis in and then worst of all ... stagnate.  That 'appeal' of the blended look is a residence that has a lease far longer than the preceding warm up.  So it's really kind of a net loss for the Springers.  hm. 

Anyway, shrubs have burst out in leaf and flower.  Now the major's buds just since Friday have swollen like a teenager that just found dad's porn stash..  This might be forth year in a row that did this here in the N-central interior of eastern Mass. We enticed the flora into the celebration just to then throw a later, cold antithetic pattern at the landscape.  I have family in the orchard world and they're saying it's been a bad few years with later frost/freezes stressing production. Wonder if this is the same or if it's more like a 48/40 hell instead.  

Best to just enjoy today and tomorrow.

Hope this is correct for CT

 

It should be better for spring enthusiasts in CT than east of oh ... say 91 (N-S)...  

You can really see that on the NAM from 12z.  It has Logan Airport at 35 F at 6 PM on Tuesday afternoon!  In FULL sun...  with a gentle flag wobbling easterly sting... Meanwhile at that same time, ALB is 55 or so... 

I think it is possible the NAM is excessive with the cold anyway, but still...even correcting for that, the idea of high pressure centers that are retreating NE is a bad omen for eastern NE. Once you get to CT though a NE wind is actually a land direction, and thoough the air is not "warm" by any measure of reason, it won't be the same back east where it's like exposed to the freezer door.  I could see a backyard thermometer or two being 61 out toward western CT while it's 40 for eastern Mass coastal towns.  

OT...but man... if this doesn't fit into the same old 15 year long saga where the NE U.S. has a permanent cold sink compared to Global Warming everywhere, as repeatedly and persistently reported by NASA's 'state of the planet' address that comes out annually every January. It seems we here in eastern North America et al (actually) are kind of protected by circumstance of that anomaly.  

But, it probably wouldn't register sensibly ...as in, to the skin; after all we're talking about decimal increases per annum.

We have one of the weirdest temperature jumps going on that I've ever seen on the mountain.

Its like all the snowpack is funneling the cold air down the drainages on the mountain and its pooling at the base of the mountain.

I've got 53F on our sensor at 1,500ft while MVL down in town with no snow anywhere remotely close to it is 71F. 

We keep bouncing from like low 60s back to the low 50s when another push of cold comes down the mountain.  You can see it too, there's like a 10 foot thick layer of ground fog over the snowpack in these cold pockets (probably because the dews are in the low 50s too) that rushes downhill...most pronounced in the gullies and drainages.

Its bizarre...and even skiing you can feel the warm to hot pockets mixed with cold pockets depending on where its mixed out and where the calm air over the snowpack has allowed for a refrigerator type effect.  The effect is so pronounced that people's ski goggles are fogging up as you change from these different air masses.  Its like one spot its in the 40s and then 50 yards down the trail its in the mid-60s and you fog up.  

I think so much snow melted in the humid thunderstorms last night that we have exposed another very cold layer of snowpack that's been solidly entrenched on the mountain probably since Christmas and its now getting exposed to the warm humid air.  That's the only thing I can think of.

That's interesting. You think winds more SW to WSW perhaps are becoming more perpendicular and thus sort of going up and over the mtn vs straight up the valley floor? Winds near summer are probably 230-240?

Yeah we are definitely CAD now or something.  

We have warm sectored aloft but have actually gotten colder at the base of the mountain today.

It was 56F at 4am when I got here and now it's 52F on our control station in the base area...it's even giving a wet bulb temp lowest in the base area vs the other elevations.

I questioned it so much (maybe sensor was wrong?) that I just went to my car and drove around a little and it's legit.  My car says 51F at 1,500ft.

Its low 70s at MVL at 750ft!

This is the largest temp difference I've ever seen between MVL and the base of the ski resort.

Winds are SW at the summit and going over top us...it's dead calm at the base while it's 40mph at the summit.  

I wonder if the snow (still 10-12" at the stake at 1,550ft) is causing some CAD feedback or something?  When it was raining last night it was warmer...now it's dried out with some partial sun and it's gotten colder somehow (while the summit has warmed 10F).

Interesting meteorology.

PF,  I bet if you could color dye the air it would look similar to the fog coming over the hills like in the bay area around  San Fransisco.  The warm SW air is coming over the ridge and slowly draining down the lee side.  The air is running over the snow pack and keeping the base like a freezer.   I bet its just the lowest couple of hundred feet.  Would be fun if you had  a balloon or drone with a temperature probe to see what is going on just over head.   Something similar is happening here right now.  I'm 78ish  but if I drive 1/2 mile down my hill into a protected gully area there is still snowcover and you can feel how cold it is.  The ridge to my south is protecting the gully so it is not mixing out even this afternoon.  Micro climates are amazing as you well know in your area!

Spring weirdness.  At 4 PM it was 85 at PWM, 47 at FVE.  Your experience on skis reminds me of the northern Maine woods during the first really mild (60s there) days.  If there was a breeze - usually the case - one could stand still and feel alternating mild and cool puffs, as air from open hardwood areas alternated with that from under the evergreens.  (The other phenomenon would be the sequential slumping of the snow, with the first "whump" underfoot with accompanying dropdown, then the sound continuing [whump, whump, whump] off into the distance as more area settled.)

Pretty surprised to see just a band of light rain approaching on radar.  Based upon the sky, I was expecting something pretty potent. Sky got super black and ominous.

I'll take that back, it was pretty potent.  Wind was unexpectedly epic for about 5-6 minutes.  From the WSW down the length of Paugus Bay, which built up waves about as big as you'll ever see on this part of the lake.

Measured a gust to 42mph.  Lights flickered and a few branch pops were heard in the pines.  Very nice.

pretty decent Dcape values in place and sweet inverted v look on soundings!

Newfound Lake was about 1/3 ice covered mid afternoon.  Front/trough came through around 6pm with 40mph gusts.  Too windy to take the drone up but from my vantage point much of the lake opened up all within an hour or so.  I still see some ice in the bays but wow what wind can do with black ice!
