Here’s how long the heat will linger in Whatcom County

A heat advisory is in effect as high pressure draws hot air toward Whatcom County, driving temperatures into the 80s and 90s and allowing some wildfire smoke to sweep through the region.

A high temperature of 87 degrees is forecast for Bellingham on Friday, July 30, but the Mount Baker foothills and areas near the Canadian border will be much warmer, according to the National Weather Service in Seattle.

That’s 10 to 15 degrees above normal, according to NOAA data for Bellingham International Airport.

“Very warm temperatures today and Saturday before marine push Sunday brings temperatures back to near normal,” meteorologist Dana Felton said in the online forecast discussion Friday.
