July 21, 11 PM Weather Forecast Update Active forecast: Smoke, bad air, heat wave with dangerous heat indices & some storms with severe weather risk.....then a brief, but nice cool-down (before it heats up again & we see severe weather). All now to August 7. Posted: Jul 21, 2021 9:24 PM Updated: Jul 21, 2021 11:23 PM Posted By: Chad Evans Wildfire smoke was the thickest yet for Summer 2021 for our area. Thick layer of smoke at several thousand feet up blotted out the sun. This smoke is from fires in the NW & W U.S. to Canada. Meanwhile, smoke from the N. Minnesota & Ontario & Manitoba fires arrived at lower levels & mixed down to the surface, dropping visibility.
