39.1° and deep blues. Drip baby drip.

Upcoming -WPO punge is progged to be the lowest in March since March of 2017:

and thats why I was happy with winter. We actually captitalized on a good period, and were able to hold the cold....and snow. Had that not happend, I'd be rather bummed and less "curvy" w/ my B+ grade.

Oh, right... LOL That also reminds me, that December 2020 massacre.. I think some places lost 18" of pack in a single night. I guess maybe we can draw a distinction in "melt reasons" - if nerdy enough. heh. Like, if it's raining with 50 mph gusts at 55 F... you could decap Greenland with that. Kind of a different sport. This coming up will zephyr winds under sun with temps (maybe approaching 70) and DPs probably nearing 50 - who wins and how much

Absolutely... The old timers knew that... Some of new crews are just figuring that out...

it's gorgeous out honestly, was a mess earlier but everything falling with full sun and soaring temps.

Still unsure what mid month brings.

Clearly we are struggling with this inversion. Probably won't last the whole daylight. At some point, we see the temp surge 5-7 but everyone's at 10 am was struggling to touch 40 on a day that I feel pretty confident, if there were no snow pack, we'd already be in the mid or upper 40s heading for +3 to even 5 F MOS bust. This is sorta related to what Brian and I were just discussing. Unless you have a lot of mixing/turning over of the atmosphere, still boundary layers isn't really how to warm the air over a snow pack. That said, the DPs are rising with the temp. It's just 40/34 at FIT. This is the warm DP ( I have seen ...) combined with above freezing air in months really. It may have happened ... but not with a post solar min intense Equinoxian sun

I do that all year round Will be tough to top January 1996 for land-snow retreat rate.

Um yeah. 40 dews and low 50s temps.

As of March 4, 2026 ASH> 68.25"+/-

Yeah, perfectly stated.. I like the reasoning with the Oct sol comparison, too. I do that every day in my head in spring... 'today is Oct 8 sun' as an aside, part of me grins like ...why do that. I should just know at the scalar point what Mar 4 solar is, but for some reason, the autumn comparison helps. weird. Anyway, no problem slashin' T's there. I think the best part of that 10th and 11th will be watching perhaps the fastest land-snow retreat in history. heh

hoping the sun pops through here soon and clears the ice off the driveway

I feel like the AIs are hitting some theoretical ceiling if the surface was bare and dry. That would make sense given the sun angle equivalent in fall for Oct 5-10 where records are in the mid/upper 80s in the warm spots. But I think it’s safe to toss those readings. Slash 10°F off of those and you start getting closer to the op runs and highs from that 2/21/2018 record heat day.

Solid melt day today for many , highs 48-52 dews 35-40 bright March sun, can hear the gutters already pouring water at 10am

Well, PS: I'm jelly over her band

On the pack? Yeah no

Euro MJO goes into 8 and loops

I was thinking the same yesterday, but the east winds might put the kabosh on that threat to at least some extent.

Bonanza already beginning.

Heh... I haven't railed on about BDs since 2010. I know that. I was late getting my Met head wrapped around the total mechanics of what BD synopsis is/why ... but once that light turned on - Understanding goes a long way to ameliorating once vexations. Those are 25 dollar words to say that if you get why, it's not as frustrating nor annoying. LOL BDs are a decoupling of the synoptics in the vertical. Basically, around 250 mb above the surface ( expressing altitude in pressure) ...so ~4,000 feet(1300 m) give or take, the bulk troposphere no longer cares what's happening below that level. Down here in the basement, the air is moving NE --> SW, and above that level the pattern may only look vaguely like that could even be taking place below. These become disparate circulation modes. This is caused to happen because of topographic layout over the eastern continent. Everywhere E of the eastern cordillera, particularly E of the Berks to White Mountain axis... there is a drop off in elevation down to sea level. Given the normal trajectory of the westerlies ( flowing WSW or W or NW over those elevations, causes a "curl" vector which points back SW underneath as the elevation descends. That vector is overcome much of the time... such that we dont' have a BD flow always. But, at other times, such as when there is +PP ( pressure pattern) over Maine/GOM/Maritime, that imbalance will take advantage of the vector immediately. Rollin' on back SW the air comes, because air always moves from +PP to -PP. That action of doing so, is the uncoupled state. There are reasons by the +PPs set up. They range from S/Ws moving SE out of Quebec toward the lower Maritime, where backside NVA/downward motion piles the air. There's a cold front up there that passes by and piles air precariously close to the vector ... so that can get the air rolling. The other way is just aggregate cold Labradorian current modulated air density, which is intrinsically +PP in a narrow lowest level. If that sniffs the vector, it'll start rolling back SW. Kind of a fuzzy different between that kind and seabreezing. In March through early June really ... both these kinds of BD means are aplenty. So anyway ... in understanding all this, heh. It's built in.

40s dews will do some damage. Especially with sun. I will say that mesos were hitting that foggy/cloudy spot in the CRV in MA/CT for days indicated by a cool spot in the afternoon on the 2m temp progs. I was curious to see what that was going to look like if it was real….well voila.

Snow at Logan, rain for Jerry?
