Record Heat Settles Into Seattle

While temperatures will remain on the warm side in Seattle on Tuesday, even hotter weather is on the way.

The heat will turn up on Wednesday with high temperatures climbing above 90, nearly 20 degrees above the city's average high for mid-September.

By Wednesday evening, temperatures will fall into the upper 80s, just in time for the first pitch of the Seattle Mariners game when they play at home against the Houston Astros.

Record-challenging heat will continue through Thursday, although temperatures are not expected to be quite as hot.

A northward bulge in the jet stream is responsible for these unseasonably hot temperatures, allowing warmer air to settle in over the region and limiting the cooling factors that the Pacific Ocean plays on areas near the coast.

The last time Seattle cracked the 90-degree mark was back on June 30, 2013, when the city climbed to 93 degrees.

Seattle is forecast to reach 92 degrees on Wednesday, which is five degrees higher than their record high of 87 set in 2009.

The possibility also exists for the city to break their record high on Thursday, currently forecast to reach 88, with a daily record of 85 set in 1975.

Temperatures will ease a bit by Friday with highs retreating into the lower 80s.

Although this will feel more comfortable, these temperatures will still equate to 10 degrees above normal for Seattle.
