If it felt to you more like Dallas than Seattle on Wednesday, you’re not crazy. The heat was on par with the Texas city’s — 93 degrees at its peak in the late afternoon. That broke the previous record of 87 degrees for Sept. 11, set in 2009, according to the National Weather Service. It also tied June 30 for the hottest day this summer in Seattle.

It was hotter Wednesday at Seattle-Tacoma International Airport, where Seattle’s readings are taken, than in Las Vegas, which had a high in the 80s. At times, it was hotter here than in Phoenix, which hovered in the low 90s.

The heat was caused by a high-pressure front drawing warm air off the mountains, National Weather Service meteorologist Johnny Burg said.

The air is expected to be a little less stifling for the rest of the week as that front moves out.

Some areas of fog Thursday morning are expected to gradually clear, and the high will be a little more tame, around 84, in the afternoon, the Weather Service reports.

No rain is in the forecast, though, at least not until Sunday, when there’s a chance of showers that continues through next week.
