Chief Meteorologist Justin Stapleton’s Thursday Forecast Discussion
Some hot spots out there today as Corvallis hit 99, Portland (PDX) hit 100 and Roseburg at 97. Folks in Eugene saw 94 but it was smoky with the Buckhead fire billowing smoke into the Southern Valley, keeping out temps a bit cooler.
Because of the heat, the Willamette Valley is under an Excessive Heat Warning through Friday 9pm. Highs tomorrow should be a degree or two cooler but still well warm for most. Expect mid 90s in Eugene, likely upper 90s still in Corvallis and down in the Umpqua Basin. Folks with heat sensitivities and/or anyone that will be outside during the peak heating hours in the afternoon should make sure you can find some shade, take breaks, and plenty of water. That includes everyone headed to the Lane County Fair tomorrow.
The heat will finally break down (slowly) on Saturday with winds switching to in off the ocean. Highs will fall back into the upper 80s and low 90s. However, an upper level low swinging north offshore and the highly unstable air overhead, will trigger some hefty thunderstorms for both Saturday and Sunday in the mountains.
Next week we’ll be back to a more seasonal forecast with highs in the low 80s and morning clouds giving way to afternoon sunshine.
Have a great Friday!
