The heat is ON!

Clear skies were in place Friday evening, perfect for the return of King Felix down at Safeco Field, and with temperatures reaching the low 80s in Seattle, making for a fantastic night to watch some baseball or have some friends over for dinner out on the patio.

Temperatures soar even more for the first weekend of summer, with some spots hitting 90 degrees on Saturday, especially in the south interior and into the foothills. Sunday will see many places reaching or surpassing 90 degrees, and as such, a HEAT ADVISORY has been issued for Saturday afternoon through Sunday evening. The culprit for these scorching temperatures is what’s known as a thermal trough: an area of low pressure associated with a very warm air mass. The Puget Sound region will really see the effects of this thermal trough starting tomorrow as it skirts the coast, bringing with it a near 10 degree temperature jump in some places. While understandably eager to hit the lake, keep in mind that it is early in the season, and lake temperatures around the region are only around the 50s to 60 degrees, so do be extra careful as you cannon ball into the lake to cool off.

Monday will start to see some relief on the coast as our natural A/C kicks in, with winds shifting from northeasterly to westerly. This should hold temperatures in the interior to the mid-80s, while the coast drops back down into the 70s. Hikers should be aware of a chance for some thunderstorms up in the mountains, especially if you’re south of Mount Rainier. Relief comes Tuesday for everyone as the marine push moves inland, bringing temperatures back to the low 70s.

Enjoy the warm weather, be safe, and have a great weekend!
