dendrite

ineedsnow posted a 60” one in PA weeks ago. But I only save fantasy maps that crush me.

I’ve seen remarks in some of the obs. MWN seems to have retained theirs. I just picked a random date range here but you can see some of the icing and cloud comments in there. https://mesonet.agron.iastate.edu/cgi-bin/request/asos.py?network=NH_ASOS&station=MWN&data=metar&year1=1984&month1=1&day1=1&year2=1984&month2=1&day2=28&tz=Etc%2FUTC&format=onlycomma&latlon=no&elev=no&missing=M&trace=T&direct=no&report_type=3&report_type=4 Found me some aurbo obs too MWN,1982-02-02 02:00,KMWN 020200Z 32065G89KT 90SM CLR M13/M16 A//// RMK TOPS LWR SCT 50/AURORA N SLPNO T11271155 MWN,1982-02-02 03:00,KMWN 020300Z 32064KT 45SM CLR M13/M16 A//// RMK SLPNO T11281156 MWN,1982-02-02 05:00,KMWN 020500Z 32052G62KT 90SM CLR M11/M29 A//// RMK AURORA N SLPNO T11101288 MWN,1982-02-02 08:00,KMWN 020800Z 30033KT 90SM CLR M10/M31 A//// RMK AURBO W-N-E SLPNO T10991305

Ha. He does from time to time.

6z nam is north of the euro now

We get clowns like that a few times per winter

Looks like CT is stealing my snow again

I guess I’m just having trouble understanding how you’re getting that strong of sfc lapse rates and differential heating aloft on the mountain side snow surface. Do you get whirls like that during warm season?

Dust devils rely on hot surface temps…snow sfc temps are relatively cool because of the albedo. Since they’re often on mtns…I’m going to guess they start as a local swirl/vortice that strengthens as it slides down in elevation as it stretches vertically and tightens and speeds up like a figure skater.

SREFs? ARPEGE?

60 at 4pm and then 9.5” by 7am.

The old form for Norfolk from May 1977. Fun times.

Let’s do a few big events with 40s and 50s in between.

Go big or go home

3 months of 45° and rain incoming soon

The person on the bottom right was the first thing I noticed. A shovel with like a 5+ foot handle where it looks like the shovel portion should be below the surface. But yeah, people in similar positions and the signs. And who uses those flat shovels anymore and shovels into blue buckets that you won’t be able to move?

What a weenie drought monitor that would be. Look how happy he is viewing that.

I think he knows. I read his twitter post comments later. It happens.

Some of it was luck.

That top pic is clearly AI lol

They fly up 20ft and it’s 20F warmer

Speaking of twitter…I was thinking how it’s been a tough winter for Fish to troll ACATT, but it’s nice to see him still trying
