When I said it was cold out there earlier…Pope said we didn’t know what we were talking about. 

Yeah full on Spring today.

No free ranging today.

What a way to run a weekend.

Lmao…it’s horrid out, 37 degrees with mist.  Pope drunk.

Sounds like a good job for CoastalWx!

Odd that the HRRR just picked that one area repeatedly.  Why didn't it do it for other mtn peaks that were even higher then Brace Mtn in the area?  The 3 km NAM does this systematically all the time for all higher peaks, but HRRR singnaling out one mtn for multiple runs?  Not sure I have seen that before.

So did that peak get blasted with 20”?

12z gfs /gefs continues to show pretty big changes next weekend (18th-20th) and beyond.

I’d bet top of WaWa had 10+….best was slightly south of you too. 

I bet Watatic had 10+ too. That's a fun trek in the fall

Well if we go by your 360 hour maps last night's Euro doors us into the 40s on April 27th.

Yeah it could suck, too.  At least at times it probably will, but hopefully we sprinkle in some 60's and 70's

[rimetree]

Most of tomorrow looks shot now too with that low backing in.

Yeah Ashburnham had 9” so top of Watatic likely broke double digits.

Just rain thankfully.

 

girl I went to school with lives in southern NH and she just posted quit a a bit of snow on her instagram story. Little surprised some areas are seeing close to half a foot 

Nothing but rain up here on the other side too. One of the few times I am actually happy to be missing out. Those that got it, can keep it this time of year.

This was a pretty classic dynamic spring blue beauty.   The sounding was very isothermal below the growth level ...right around +.1C   ha... seriously though, a little bit of aggy action suspending through that was going to drill the surface to the freezing point.  We were 32.4 here with 3.5" ...settling immediately to 2 by midday and now grass blades are poking through.

Yeah kind of a positive spring bust of yore…interestingly, guidance was generally more aggressive earlier in the overnight period but that part kind of failed. But then we got that blob of monster omega around 5am and things went gangbusters for roughly 2-3 hours and that’s when 90% of the accumulation happened.

It's more than just that look though. 

Two aspects leap out to me that suggests this is when spring really begins for us:

the first being that the troughs stop amplifying as they are moving toward 80W around D5/6     That behavior is significant. 

the 2nd aspect is that while that is happening, the 540 dm thickness retreats to above 55N also beyond that time range.  

Altogether, right around that 120 to 144 hours, the local hemisphere fundamentally changes the mode toward a better seasonal correlation.  This ridge above is "extra" on top... Even without it, we'd probably be 40s by night and 70 chances by day.    BD season notwithstanding but that's more local. 

The only problem I'm seeing is the WPO ( west pacific oscillation).   It's been excessively negative...  This has transmitted an unwanted wave signature downstream through the PNA domain ...ultimately driving tendencies for troughs to dig and cold here in the east continent...  It's not abundantly clear if that's really changing.  The recent ensemble means do suggest it's trying to reposition toward the Date Line ... which sends a -EPO on a west limb surge... That drops the Great Basin heights and up the eastern heights go... the operational runs seem to be responding to that forcing lately - that's what we're seeing.  So the sensitivity seems to be related in getting all that to actually happen...

And by the way ...I had a pretty good girder buzzer thunder rumble in the 2-3 hour period.  It woke me up and I looked out the window at very low visibility.   Short and sweet though.

It’s the 92nd anniversary of a major paster up here. CON had over 18” and the COOP here in Franklin had 35”. I went back and looked at the form earlier today and noticed the observer put “blue snow” in the comments.

If observing were like this now I'd be fired

That’s quite the ratio for mid April and a min temp of 32F….34” on 1.25 of liquid that one day. Wonder if they left the core boiling over the fire too long, lol

Haven't talked to her but I bet the mother in law at 1,360 in Ashburnham got close to 10 or so

Yeah I’m inclined to toss the liquid. Lakeport had 2.96” w.e. I believe and Plymouth had 26.5” snow. I wonder if it was a Dec 2020 type event given how quickly it fell. 

[dendrite]

35° with a sleet shower. High was 36.6° at midnight. A true winter day.

Blue snow is a result of the high liquid water content.  You typically only see that when you dig into the snow and there is more then a foot on the ground.

Yup. Have had plenty of those over the years. I just always think of Tip when I see it in print.

This weather has got to end right? I have people calling me for firewood.
