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
April troughing is okay. When we have nice breaks like we did last week it makes it feel pretty good. Some rain, some sun and I'm good.
The mountains are going to be picking up some good snow pack.
Gonna hit Rattlesnake Ledge tomorrow. A few weeks ago it was pretty icy near the top with some light snow falling. Probably picked up more snow today though.
Tim, how does the snow line look up your way?
Maybe the second half of April. In the Ag Weather update yesterday they talked about the MJO going into phase 6 or 7 next and that usually means PNW troughing in April according to their maps.
