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
Sort of funny... I only saw the left side when I glanced at the post earlier and thought 80s for highs can't be that bad. Only when you quoted it did I see the actual high temps. Ouch.
I think their 2" on August 24th 1992 is absoluetly f****** absurd. At least in June there is just enough residual wintertime cold left over at the poles to drop snow levels down to 5k feet should it be displaced south, and enough of a poleward thermal gradient still in tact to spawn strong-ish cutoff lows around the meridian line. Mid-late August is a joke of a time to get a snowstorm, even at their somewhat high elevation. They pretty much combined the strongest weather system possible at that time of year with the coldest air possible... Neither factors being very impressive nonetheless. But enough is enough. The only month I doubt they could pull off a snowstorm at all would be during July, and even then I bet the first week holds some out-there potential in the right setup. July 15-August 15 is off the table though. I think....
