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
After enduring the 2013-2019 stretch I really don't like to hear that. Especially given the extra decade of warming since then. No subfreezing highs here during that time period and a bunch of missed snow opportunities. Granted there were some ideal setups that we ended up rolling duds on every single time, which is super unfortunate and admittedly rare, but a stretch even half as boring would still test my love of this climate.
(However it did make Feb 2019 all the more special!)
Interestingly, most of the 3+ year niñas followed strong/super niños.
This one is backwards in that respect. The only match to this progression is 1954/55 -1956/57.
Super niño followed 1957/58, but uniquely, did not recoil back into La Niña afterwards.
In fact, the next 13 years only saw 1 weak La Niña, with 6 El Niños in the same span.
Back in 2016 or 2017 I remember pounding the drum for a heavy La Niña cycle in the early 2020s. The intradecadal IPWP oscillations tied to the solar cycle & QBO made it relatively easy to time.
Same forcings that brought it about are flipping now. Approaching solar maximum, IPWP is set to extend eastward after this El Niño for another 5-10 years.
