Kick-Off '25-'26 Winter Storm Obs

[TheMainer]

About 4 inches of at least 15:1 fluff in PQI, wife had early dismissal from school (teacher) back home and said we had close to 3 when she got home, but she's been sitting by the wood stove since then so no updates

Getting into the heavier rates now, have some ground to make up to get to GYX forecast. 5” atm. Really nice wintry scene out there

That’s gorgeous.

CC not showing any signs of collapsing. Thing is cooked.

Looks like 6.5” will be the final here

 

[ineedsnow]

Hrrr doesn’t flip us back until after 11pm now. We’re prob not gonna get much late snows.

Nice event for your area Dave.

Looks like my 4-8" zone for the all snow areas will work out....I just didn't see the huge rates/amounts with that shitty SG.

I guess I wasn't in that zone.

All right that's enough of the gloating. Powderfreak South.

Never ignore the NAM sniffing out a warm layer above the surface. Not sure anything else had sleet up this way. 

[CoastalWx]

3K Nam didn’t  really have a sleet look. Probably half ass flakes that melted a bit and refroze.

[Chrisrotary12]

Peeling paint off the windows now

This was a really weird sleet event. Not common you get sleet with a warm layer around 900mb, lol. But I agree it was probably not-fully melted flakes refreezing quickly into pellets.

32/30 -FZRAPL 3.8" total accumulation with a light glaze on top now

[WxWatcher007]

3.0 to my NW. A hair less here.

I don't know if there's any actual significant correlation between these two variables, but it seems like you need a deep and rapidly intensifying low pressure in order to have a successful backend "flash over". Mbs in the 990s, tilted mid levels, and rapid forward progression just won't cut it.

Kind of a weird SWFE hybrid rather than a true coastal. Big warm nose etc... If you can't stack the lows, the dynamics just aren't as good for the development of a cold conveyor belt

Nrly ageo flow at the surface and then ripping srly from 950-850. With a low south of ACK. In all my career I cannot recall such an event.

[Snowedin]

Just a cold, wind driven rain event here..nothing out of the ordinary for early December in these parts. Beautiful pics from the snowbirds to the far north. The fluffy powder really does brighten things up this time of year.

Reports of 7” in Fitchburg and Lunenburg 

[dryslot]

Some of the heaviest rates on the day about to move over the area as SPC has issued a bulletin for 1/2-1"/hr rates.

You sure its not 17" in Lunenburg?

I said late last week, would this be a sort of hybrid(half coastal, half SWFE), and I believe it was determined at that point that it would be a coastal.  But in the end now…it wasn’t quite a true coastal it seems. Interesting.  The cold was never scoured out here…that’s rare when you have warming like that 950.

Really effing weird. Sfc low almost got elongated too to the northeast. Yet we had 925 taking forever to close off and ripping from 180-170.

SWfE usually have a primary well west and ripping srly flow aloft where the 800-700 layer causes sleet. Tbis is just a weird one.

[CoastalWx]

About 1.3” rain. 

[mreaves]

About 4.5”. I don’t do the ratio stuff but it is pretty fluffy. 22°

Models can't initialize this storm to save their life. The hrrr is completely missing the big band over Northern Vermont. Pretty garbage model performance all around, from the medium to short terms
