The normal high temperature inSeattle for the Fourth of July is 74 degrees, and Pinpoint Chief Meteorologist Morgan Palmer says we're certain to be warmer. However he points out that high cloud cover is likely to be increasing in the afternoon, filtering more of the warming effects of the sun. While the atmosphere is otherwise set to produce a pretty hot day with highs in the mid to upper 80s in Seattle, this high cloud cover is likely to knock a few degrees off the afternoon high temperature.
While we have been cooler with occasional light rain recently, Western Washington is still very dry, with much of the region from Seattle southward officially in "moderate drought" status.
With lower humidity, afternoon breezes and high temperatures in the 80s on Wednesday afternoon and evening, any accidental fire that make their way into dry brush will be able to spread quickly.
Palmer says the hottest Fourth of July on record in Seattle was in 2015, when the mercury hit 92 degrees. The coldest Fourth was way back in 1903 at 58 degrees.
