This means that a tropical storm is working northwestward from the Gulf of Mexico, crossing into Arizona, southern Nevada, and California. The sky is overcast - grey all day - but with relatively high temperatures; today was in the high 80s to low 90s(F). This is what Californians call "muggy." We couldn't survive in 90% humidity!
This monsoon pattern will last a few days, then we'll be back to hot (105F) and dry (10%).
I worked up a tropical sweat in the studio, weaving on the painted-chain table runner warp. It was fun to see the painted stripes change as I wove. At the beginning of the warp, the painted chains were the same color as the surrounding narrow stripes of red, but not for long.
Apparently, I didn't line up the two right-hand painted chains very well, and there is an occasional offset between them. Oh, well. More visual interest, right?
