Temperatures climbed into the upper 90’s on Tuesday afternoon. The next couple of afternoons will also be toasty, but relief is in sight. By the weekend, highs will drop back down into the middle 80’s.
A ridge of high pressure has been building over the Pacific Northwest, which has helped afternoon temperatures reach values nearly ten degrees above average. This ridge remains in control until a cold front moves onshore towards the beginning of the weekend. After the front passes, temperatures will drop nearly ten degrees, and those cooler temperatures last all through the holiday weekend.
A few showers are possible Saturday for the northern Cascades and along the coast, but other locations should stay mainly dry. However, do expect increased cloud cover for Saturday and Sunday. By Labor Day on Monday, mostly sunny skies return and temperatures will still be slightly below average.
