January 24-26: Miracle or Mirage OBS Thread!

[WxWatcher007]

As @Bob Chill used to call it. Cold powder...hope you can all hang onto SN+ as long as possible. 

[clueless]

Change over here off is Evergreen Mill in Leesburg. Sigh. But what a beautiful scene. 

[heavy_wx]

I measured just over 4" of snow here in North Bethesda with moderate snow falling currently. The aggregates are mostly compact indicating less than optimal snow growth at temperatures > -10C and possibly some riming. I did see a few dendrites mixed in so there is still some growth occurring at temperatures < -12C.

That is nasty stuff. Can’t imagine how many power outages there’ll be and a cold week ahead at that. Not ideal.

yep that is why my job moved me up here because of a much lower chance of losing power.

[Ji]

Changed back to all sn, still accumulating. 4.5”

How did it flip to sleet there? Data center lol

You’re one of my key upstream weather obs in this setup lol. Brunswick, too.

Must have been temporary warm pocket upstairs. But my hours (minutes?) are numbered

I also hope we stay sleet and then dryslot before zr

You could be right, it was dark and hard to tell. Just saw those things bounce off my hand

14 and heavy snow. Almost 6” on the ground

6 inches where?

Appreciate the report!

[RickinBaltimore]

Snowing heavy and about 3-3.5" here. Peaceful though and quite relaxing.

[ifindppl]

Still snowing heavily in Olney.  Can hear snowplows off in the distance from my back door.  No sleet, no pingers.

[Ji]

How accurate are these? Versus people obs?

[EastCoast NPZ]

Just starting pinging here.  Smh.

[hsq]

4.25” in Huntingtown.  I’m in circled area, still no sleet mixed in… yet. Also, a few wind gusts in past hour have been a ton of fun!  17F

I figured the sun was out by you

[WeatherShak]

People seemed so focused on the snow that this is getting ignored. Hopefully the models are wrong, but that could be very bad.

Yup. I don’t have 10 gallons of kerosene, two generators and a cord of wood for 6 inches of snow.

Allan (Raleighwx on Twitter) said a lot of central NC stayed sleet most of the night. Maybe a glimpse at our future?

I hope it's that after the flip and not freezing rain!  My p&c holds off freezing rain until this evening

Mod snow, about 4" and 14 degrees

(Germantown)

[SnowtoRain]

Wind is starting to really pick up In Easton, moderate snow, 3 to 4", 14.9

There is likely some partial melting of the aggregates, ahead of the more visible reduction in correlation coefficient, causing the ice particles at the surface to become more compact. A mix of fully melted liquid drops and partially melted ice particles is typically needed to produce the observed reductions in correlation coefficient within the melting layer.

Mainly sleet now…bummer would have like to seen the SN+ in the daylight

That's probably next.

100% sleet now.

[stormtracker]

I need this in my life 

[nw baltimore wx]

Swept off the covered porches and shoveled some, and it's so cold out there.  Just beautiful. Someone wake up maestro so he'll stop complaining.

Sleet? And a phone charger?

[EHoffman]

Snow quality has really declined here, tho it's still ripping.  Lots of rimed flakes, some dendrites mixed in too though.

Dang! Really? Still snow here two miles from you. Taking the foxhound for an ATV neighborhood ride soon.

Might be sleet.  And yeah, I almost never let my phone get that low
