    Portland Heat Breaks Record With More Heat on the Way

    Temperatures will be on the rise in Portland over the next few days following a warm start to the workweek.

    The heat began to turn up Tuesday afternoon as the mercury climbed to the 91-degree mark, more than 10 degrees above normal for mid-September.

    Temperatures continued to rise on Wednesday, climbing even higher to hit 95 degrees. Wednesday's high temperature broke the city's record high of 94 degrees from 2009.

    Record-challenging heat continued in Portland through Thursday, although temperatures were not 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.

    Portland had not broken any high temperature records previously before Wednesday, and this week was possibly the last chance for the city to do so before autumn arrives later this month.

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

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

    Sunny skies with plenty of sunshine will remain on Saturday for the Rose City but on Sunday temperatures will drop into the upper 70s accompanied by a couple of thunderstorms during the afternoon.

    Sunday evening is forecasted to be cloudy with an occasional shower.
