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
A secondary MCS hit us around 3am but it seemed to have a lot less wind packed in it, it was more of a lightning and heavy rain producer. There was a couple hail chunks but it was too mixed in the downpours to tell how big.
That line was a tornadic QLCS back in western KY last night.
64 and partly sunny here. There might be more t'storms later but we're past the brunt of the whole thing.
The heat spike and pattern retrogression is still there on the EPS after D10. But crazy how everything keeps getting pushed back.
If you recall *last* week was originally supposed to feature the western death ridge (according to the GFS). Now it looks like the second week of June.
I forgot how useless the GFS is in GOA trough pattern in the spring/early summer. Always the same errors.
The official H/L yesterday at Grand Rapids was 75/50 there was 0.43” of rainfall. The sun was out 23% of the time. The peak wind gust was 40 MPH out of the S. Than came in a heavy rainstorm with some thunder and lightning. For today the average H/L is 74/52 the record high of 93 was set in 2018 and the record low of 30 was set in 1961. The most rainfall was 1.12” in 1982 Last year the H/L was 79/43.
The overnight low here in MBY was 58. I recorded 0.43” of rainfall during yesterdays rainstorm that had some thunder and lightning along with some strong wind gust, the wind brought down some small tree limbs in my area. At the current time it is 58 and cloudy here.
