NASA's Juno mission recently detected "shallow lightning" on the surface of Jupiter. This shallow lightning forms from ammonia clouds, not water clouds like here on Earth. Interestingly enough, it was this week back in 1999 when Western Washington experienced a lightning show for all time. A swirling storm off the coast produced vivid lightning August 3-8, 1999. In total 9,800 lightning strikes were detected with 36 of those occurring within 5 miles of the Space Needle according to Andy Park, a summer intern at the National Weather Service in Seattle.
Luckily no lightning today, just summer showers across the NW Interior later this afternoon. While Puget Sound stays partly sunny, an advancing cold front will turn the sky cloudy from Forks to Bellingham and bring light showers to that area by dinner time tonight. While the majority of this rain remains north of Seattle, can't rule out a few drops of rain spilling south over the area Saturday. But most backyards will stay dry this weekend with typical early August weather.
Monday will end up being the warmest day of next week as temperatures reach 80 degrees across Puget Sound. A strong pull of marine moisture soon thereafter will increase the clouds and cool conditions down slightly by the middle of next week. Summer showers make a comeback on Thursday.
