PWM event total 14.2" / 0.92" Depth 14" (was 4" prior to the storm)

PWM - 05z obs 14.1"/0.91" Total Maybe another tenth or two left. Notes are usually more neat, but this has been a fun, prolonged storm. Hoping the rest of this stretch delivers more.

Christ on a cracker

Highest vibes in a long, long time in here.

Pretty rare PWM has higher ratios than CON. 9.5"/0.68"

05z PWM Obs 4.8" new / 9.5" total 0.35" SWE (0.68" total) Depth is 12".

Hey, @NovaScotia - real sorry about that. We got a little too excited.

PWM 00z obs 4.7" new/total 0.33" SWE 9" depth

Major climate sites (Logan) measure at 12z, 18z, 00z, and 05z (during standard time +01 for savings). Observers try to report to the NWS within 30 minutes.

What am I looking for on velocity that identifies the CF?

Overheard at the rink this morning: "It's only supposed to snow for 6 hours so I don't know how we're gonna get 3 feet." Nearly bit my tongue all the way off. OVC 2°/-10°

Great idea. Average scroll time of 90 seconds. Weenies enter thread, tug away, , leave.

Hey, buddy. Just like old times. Enjoy.

Never thought I'd see the day where we're calling 2" per hour 'crap'. Shame.

Lol they updated the graphic for socials - all of 21 minutes after the first one.

MPM will dump his coffee on his keyboard when he sees this in a few hours.

I blame them for including the islands on the graphic.

I feel like I do every time I try to read that damn number over PWM.

I said cred, not pro! How'd (A)I do? 1/25–26 Coastal Storm Thread: Deep Cold + Moisture Feed = High-Impact Ceiling (Still Volatile) Big picture: We’re heading into a major arctic outbreak with a cold high pressing across the northern tier, while a frontal zone + subtropical moisture plume sets up to our south. Guidance supports a significant winter storm from the southern tier into the Mid-Atlantic, with increasing signals that SNE is now in the envelope. Over the last ~48h, there’s been a notable north shift in many solutions, tied to greater interaction/phasing between southern-stream energy and northern-stream energy over the Plains → deeper trough → stronger downstream ridging → farther north storm track. WPC notes this shift is broadly reflected across deterministic/ensembles/AI guidance, but also warns the unanimity could be partly a mirage due to unresolved shortwave details. SNE baseline expectation (as of 1/21): • Snow looks increasingly likely late Sunday into Monday, but exact track/gradient still low confidence. • Ensemble spread still supports anything from “a few” to “10+” depending on where the coastal low tracks relative to the benchmark. • With the arctic air mass in place, SLRs could be higher than climo for much of the region where snow verifies. Things to watch: • Track vs benchmark (suppressed / benchmark / inside runner) • Degree of phasing (deformation/banding ceiling vs quick hitter) • Coastal front placement (I-95 jackpot potential vs sharp cutoff)

Delete this and someone with some cred start a new one with a synopsis. Please and thanks.

This is my next project after I finish the Tippy AI-bot.

Models and mets are significantly underestimating this thing.
