Good morning!

It’s a nice, cool morning across northwest Oregon & southwest Washington. Enjoy the few hours of cool conditions, because we have a significant warming trend in the forecast. High pressure will begin to expand northward out of the Southwest today. Temperatures will soar into the mid to upper 80s across the interior valleys. Warm weather will be accompanied by a breezy north northeast wind. As a result, our air will be very dry. When you combine dry air with warm temps, gusty wind and dry vegetation, our fire danger shoots up. Due to this, the National Weather Service has upgraded the Fire Weather Watch to a Red Flag Warning for areas stretching from the east slopes of the Coast Range to the Willamette Valley. The warning area will expand westward to the coast and eastward to the Cascades this weekend.

Conditions will turn much hotter on Saturday as offshore wind continues and high pressure builds overhead. Temperatures will spike into the upper 90s and low triple digits inland, and the 70s and 80s along the coast (maybe 90 in a few spots). Overnight lows will be much warmer as well in the metro area. Temps may only drop into the upper 60s by Sunday morning. It looks like we will be right around the century mark Sunday afternoon too. There’s a chance that some clouds drift in by the afternoon, so some spots may only top out in the upper 90s.

The heat wave continues into early next week, although highs should dip back into the upper 80s and low 90s for the interior valleys. Then we return to the low to mid 80s around midweek thanks to more of an onshore flow from the Pacific.

All in all, it’s going to get hot and very dry. Stay safe out there & have a great Friday!
