Really, really lovely cumulonimbus action tonight! I just happened to have my drone in the car and got some solid shots of DT Seattle/Lake Washington/Mercer Island/Bellevue looking north from Skyway. Alas, the focal length of the lens doesn't do the vertical height justice and my WB was off rendering it into semi-gross HDR territory, but still... fun looking weather! It was quite windy- I was flying right at 390 ft and the drone was giving me all sorts of warnings about sustained winds/gusts.
A most incredible snow storm. At times the snowfall rates have been as heavy or slightly heavier than January 2017. Temp 27.5, Dewpoint: 27.1 with gusty east wind and very heavy snow continuing. I'm at 11 1/2" now! UNBELIEVABLE!!!! This pic does no justice at all.
NBM is quite an interesting product! Their weighting algorithm is moderately complex and dynamic, though does has some drawbacks as we saw yesterday. For those who don't know, NBM is an attempt by NOAA to create a super probabilistic forecast model that ingests output from all the models above and outputs forecast guidance for local offices that help them to gauge the relative odds of particular weather outcomes. The 'special sauce' is the post-processing, normalization and weighting that they d
Congratulations Tanis! Glad to have atleast one great meteorologist on this weenie fest website, you have a bright future ahead of you in the PNW meteorology biz.
Back to civilization now after a successful 12 day climb of North America's tallest peak, Denali, home of some of the most extreme weather on the planet, with my 4 great friends Roger, Matt, Scott, and Aaron. For the first half of the climb we were very lucky with the weather and only needed 9 days to get enough good weather days to acclimatize and summit on the evening of the 20th. After we reached the summit we got about 20 minutes of clear sky -28 degree weather with light wind until a cloud moved in on us. Every day since then has been pretty bad climbing conditions but okay for decending, forecast calls for not a single good summit weather day until atleast the 30th so the 20th was our last summit chance for quite a while. Coolest temperature we observed on the trip was -43 and if I had to guess I'd say the highest wind speeds were only in the 80sMPH, typically you'd experience atleast a couple days with 100+MPH winds.
Feeling blessed to have had a successful trip with great weather and no injuries on the team. When I tried to do it back in the late 80s we had HORRIBLE weather for almost the entire 3 week trip and could never summit.
