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.

The 'special sauce' is the post-processing, normalization and weighting that they d
The front has moved through the area and temps today will be about 15 degrees cooler than yesterday with highs near normal in the upper 60's. We turn colder than normal for the weekend with high temps struggling to escape the mid 50's for higher spots and upper 50's in lower locales. It will be cloudy with some showers possible most likely on Sunday into Sunday night. We warm back up again by the middle of next week before we cool back down for the week of the 12th with a stretch of below normal readings.
Chester County records for today: High 95 degrees at Phoenixville (2018) / Low 28 Devault 1W (1957) / Rain 3.00" Devault 1W (1985)
Oh no! I feel so ashamed. I can't believe the guy who would be voted "most likely to have a white robe in their closet" on TWF knew about a news story I didn't.
