Thursday: Starts with a shield of high clouds overhead & thins during the day…Mostly sunny during the afternoon...Temperatures escalate into the mid-80's locally, and into the 90's from the Columbia Basin to the banana belt of SE WA... High 85°
Overnight: It'll be a sultry evening with a rusty-hued sunset, then partly cloudy skies overnight
Friday: A weak disturbance may deliver a sprinkle during the morning, otherwise it'll be mostly cloudy & muggy… During the late afternoon & evening, thunder & lightning fire up over the mountains with some of that nasty weather passing through overnight…Low/High 56°/80°
FYI: Construction has begun on "Yellowstone," one of the fastest computers ever built and the largest dedicated to atmospheric science! Yellowstone will be capable of performing 1.5 quadrillion calculations per second. That's as many calculations as there are grains of sand on every beach in the world in less than one hour!
Some like it HOT! Dave
