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.

72/64 was the hi/low. Today might feature a longer break between the precipitation, sun is already out and may fix up a more primed environment for storms. Overall nicer Spring days than we had late last week, the upstairs is a bit less stuffy now.
The official H/L yesterday was 78/53 there was 0.15” of rainfall the sun was out 34% of the possible time. The highest wind gust was 23 MPH out of the W. For today the average H/L is 66/45 the record high of 89 was set in 1959 the record low of 28 was set in 1983. The most rainfall of 1.73” fell in 1976 the most snowfall of 0.3” fell in 1954. Last year the H/L was 73/46.
The overnight low here in MBY was 53 there was 0.07” of rainfall. The current temperature is 53 with cloudy skies.
