It may not be quite as hot as Wednesday, but the National Weather Service is forecasting more 100-degree heat in the Northwest.

Forecasters say some marine air may start to cool off the region Friday, but above-normal temperatures are expected into early next week.

An excessive heat warning is in effect Thursday in the Puget Sound area and parts of southwest Washington and the north interior of western Oregon.

And a heat advisory is in effect for parts of Eastern Washington including Yakima and the Tri-Cities and the eastern Columbia River Gorge.

All-time records highs were set Wednesday with 103 degrees in Seattle, 104 in Olympia and 96 in Bellingham. Portland topped out at 106 degrees, 1 degree shy of its all-time record.
