Meteorologist Melissa Frey’s Forecast Discussion:
High pressure overhead means clear skies and warm temps. Highs will likely climb back to the low to mid 90s today across western Oregon (with the exception of the coast.)
By Wednesday we’ll begin to cool down and it’s going to get a bit more interesting. An area of low pressure will begin to move into Northern California from the Pacific. This will bring in enough moisture and dynamics to spark thunderstorms over southern Oregon and across the Cascades beginning Wednesday continuing through Saturday. Highs will drop to the mid 80s for the end of the week with at least some cloud cover in the valley.
There is a slight chance that these could move down the west slopes of the Cascades and into the Willamette Valley. It’s more likely that we’ll just get the residual cloud cover and possible rainfall from the storms. We’ll know better the location, probability and timing of these thunderstorms once this low pressure moves on-shore tomorrow.
Have a great Tuesday!
