The transition of winter to summer happens quickly in the Arctic, with the loss of snowpack and sea ice leading the way. I've got an update on where things stand this year in that annual cycle with a new post on the Alaska and Arctic Climate newsletter. @Climatologist49

Snow cover continues to decrease over Alaska and vicinity. As of May 23, low elevations now mostly clear of snow except northwest Arctic and Brooks Range northward. Meltout is not as far advanced north of about 67N as this date last year in both Alaska and northwest Canada, but more snow-free ground in western Alaska.

The Crooked Fire west of Central looks like it is under control according to a late Saturday evening report from the Alaska Interagency Coordination Center. @anisian @BakerRL75

Fairbanks Airport up to 65F for the first time this year as of 6pm AKDT Saturday. This is 9 days later than average date of the "first 65" over the past 50 years. #akwx #weather #Spring2025 @anisian @Climatologist49

Here we go. The Crooked Fire at 15 acres west of Central, Alaska. Cause is undetermined. #AKWildfire #Spring2025 #akwx #wildfire

Snow melt is progressing across Alaska and vicinity at low elevations. The Interactive Multisensor Snow and Ice Mapping System (IMS) from the National Ice Center and NSIDC for May 10 shows snow-free ground now appearing in the Yukon Flats and up the Koyukuk River valley. North Slope and most of Northwest Arctic Borough snow melt has barely started, if at all. #akwx #Spring2025 #Snow @Climatologist49

NWS Fairbanks reported "green-up" on Chena Ridge near Fairbanks on Saturday. This is six days later than last year but very close to the 50-year median. There is no long term trend in green-up date over that time. #akwx #Spring2025 @Climatologist49 @mivox @anisian @debmcqueen
