9:53 PM: Yes, just in case you’re looking for validation, that was thunder. We’ve had a bit of everything today – rain, hail, wind, rainbows (did you see the photos?) – so probably shouldn’t be a surprise. Checking to see if more’s expected.
10:01 PM: Though it wasn’t in the main forecast, we did find a mention in the 9 pm “forecast discussion” from the National Weather Service – “AND WITH SLIGHT INSTABILITY…CANNOT RULE OUT AN ISOLATED LIGHTNING STRIKE.” (The discussion is published in all caps.) So that MIGHT be all.
10:27 PM: And a weather stat:
Total precip since Oct 1 at Sea-Tac thru 10 pm on Feb 28th 37.72". Normal for entire water year Oct. 1 – Sept 30…37.49". #wawx
