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
Yes... about to be rewarded. But I am certain there will be plenty more cool/wet days between now and the 4th of July. Because that is how it works almost every year up here. This talk of endless heat and sun from now until October is pretty silly.
I had a strong feeling this frontal stuff wasn't gonna work out. It's the exact situation in which models struggle with precipitation amounts... And we struck negative, albeit with no loss of soil moisture in two days, as cold cloudy weather has prevented much if any daytime heating or sfc evaporation.
If we're speaking in strict terms, this was not a shutout. Roughly a tenth of an inch has fallen in the last three days, nearly all of which from earlier this morning, the rest few hundredths of an inch strewn about the various skiffs and bands of stratus water misters occasionally gracing us with their presence for five minutes at a time. Enough to reduce visibility to eight miles, maybe seven.
Models are more gracious with the convergence zone activity. Hope they're right
