Officially a top-5 latest first snow in Denver as of today.
We are a lock to move into the top-3, though we may finally (and probably marginally) snap this skid later this week.

2/2 (Really hope this comes through & not distorted)
I expected it to have a corkscrew motion but not quite - tho the timelapse was at the end of the event.
I’m assuming there was a local rotor that had enough moisture to get some condensation. Curious if anyone else has seen anything like this?

Was just hit by a terrain-induced convective shower in San Francisco’s Twin Peaks neighborhood, the first I’ve experienced in my time living here. The marine layer typically limits surface convection along the San Francisco Peninsula, but it’s nonexistent today, making these showers possible. #CAwx

I first wrote and cron’d the script that makes these @NWSSPC upper air maps in November 1998. It’s been running and making the twice-daily UA maps for the past 27 years at this URL: www.spc.noaa.gov/obswx/maps/. That’s over 138,000 maps online and it’s still going!

The Beaufort Sea, north of Alaska and northwest of Canada, has been slow to freeze over this autumn, with the rate of increase of sea ice extent way below normal since early October. Sea ice is slowly growing and expanding in the Chukchi and Bering Seas. #akwx #Arctic #SeaIce

Bumper crop of vultures at Hughes in Gburg. It’s still unclear if they’re using the windows for their reflection or hunting something up there. ¯\_(ツ)_/¯

St. Pierre, in “oceanic France” just south of Newfoundland, dropped to 946 hPa as this cyclone passed by at 5pm their time (2000 UTC).
They do not seem to be part of the “funky” Newfoundland time zone.
