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
That’s not true for me, but we’re all different I guess.
We used to go skiing in UT and I enjoyed snow events there just as much as here. One of our trips actually lined up with a historic spring storm there, went to bed with strong SE winds and drizzle, woke up to 12-18” of snow and strong W/NW winds. I’m still salty I slept through the overnight chaos..the progression of weather conditions basically mirrored a strong miller-B nor’easter out here.
Nov/Dec maintained the weak niña base state, but that regime imploded in January. It was quite remarkable, actually.
By February, the niño-costero signal was stronger than the preceding niña ever was. Then it abruptly collapsed in May/June, and a more substantial EPAC niña signal emerged during summer 2017 (though it was still disconnected from the PMM/IPWP state..the entire system state appeared disheveled and confused in the years following the 2015/16 super niño).
I figured you guys would have some intellectual curiosity on that front, but apparently people would rather cling to preconceived notions because of how the weather behaved in their backyards. Sad.
Lake Washington with Puget Sound in the distance.
Took off to the north then turned east right over downtown Seattle. We usually take off going south from SEA. But we usually fly in the cold season and the wind is typically from the SW in the winter. North wind today and I guess they prefer to take off into the wind.
