CHIEF METEOROLOGIST JUSTIN STAPLETON’S FORECAST DISCUSSION:
A weak “kink” in the jet stream is moving across the state late Thursday afternoon and evening. It’s sending some clouds in but most of the rain (or would be rain) is evaporating before hitting the ground. Once it moves through, skies should clear overnight leaving lows in the upper 30s to mid 40s.
The high pressure ridge regains control tomorrow, moving north and east, keeping the entire NW on a sunny and warm track for the weekend. Also, the warm air drawn in from California (the thermal trough) will move quickly across Western Oregon. That will mean another round of early summer-like weather for us through most of the weekend. Highs will climb to the mid and upper 70s to near 80 by Friday and low 80s by the weekend. Spots in the Umpqua may again climb into the mid 80s this weekend!
A cut-off low meanders into California by next week and is looking more and more like it’ll play into our weather by next Monday and Tuesday. What that will mean is probably some bands breaking off the low, bringing some thicker clouds and some triggers for isolated thunderstorms early in the week. We’ll watch where they’ll set up but its looking like more and more we’ll be dealing with some boomers next week.
Have a great Friday!
