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
The official H/L yesterday at Grand Rapids was 70/54 there was a trace of rainfall. The sun was out 35% of the possible time. For today the average H/L is 74/53 the record high of 93 was set in 2018 and the record low of 35 was set in 1966 the most rainfall of 0.80” fell in 1946. Last year the H/L was 86/52.
The overnight low here in MBY was 53 I had 0.03” of rainfall yesterday and overnight. At the current time it is mostly Cloudy and 55.
Woke up briefly and of course had to check ECMWF and EPS. That trend is what allows the ridge to build more effectively and sooner because it's easier to stretch out the trough. Also brings in more rain on Sunday and Monday. Looks more and more like a thoroughly soaking rain for the entire area and then immediately into warmth. Vegetation heaven.
