Meteorologist Melissa Frey’s Forecast Discussion:
With high pressure overhead, the sun is in full force and the mercury is climbing. The high temperature Sunday was 92°, this is 8° above average for this time of year and the 15th time this year that we’ve been over 90°.
Monday and Tuesday will both likely be in the low 90s.
By Wednesday things will 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. We’ll know better the location, probability and timing of these thunderstorms once this low pressure moves on-shore mid-week.
Have a great Monday!
