Here’s the scoop from the Weather Service.
A prolonged period of hot weather will continue through much of the coming week over northwest Oregon and southwest Washington. A strong and very warm upper ridge of high pressure that built over the Pacific Northwest Saturday will continue Sunday. It will weaken slightly Monday and Tuesday, then rebound even stronger by Wednesday and Thursday. This will produce temperatures well above normal with a good chance some records will be shattered later in the week.
Offshore winds Saturday combined with the warm air mass pushed temperatures up into the lower 90’s inland with even some 90’s in select areas of the coast. Seaside registered a high of 93 on Saturday; Cannon Beach with a 92.
Meanwhile, a weak sea breeze will begin cooling off the coast after Sunday, and especially Monday. But inland temperatures will rise back into the 90’s in most areas lasting through the end of the week. Hottest days for the inland valleys appear to be Sunday, Wednesday and Thursday with steamy temperatures lasting through Saturday.
Those sensitive to the heat should give themselves a break during the upcoming week by seeking out air conditioned areas or by heading to the beach.
