Chief Meteorologist Justin Stapleton‘s Daily Forecast Discussion:
Nice to have a cooldown today with highs only getting into the mid 70s and low 80s, while the heat was pushed off to the SE end of the state. Tonight, we’ll go into the overnight hours with a little leftover cloud cover and a cooler night than last night with lows tonight in the low end of the 50s.
The ridge that has been baking the Northwest flattens out some allowing for a stronger onshore push for the next few days. Monday will also start cloudy, finish sunny with highs at or around 80-82 degrees. Some slight chances for a stray thunderstorm in the mountains but they’ll be more widespread midweek.
A more organized trough or low pressure center drops in from the Gulf of Alaska on Tuesday and Wednesday. While the majority of the storm will move into Washington, it will be close enough to trigger some showers in Oregon, mainly on Tuesday and Wednesday. To help stir things up, with the low approaching, lots of moisture and unstable air is heading north from Nevada/California. So showers for the valleys will be thunderstorms for the mountains, with the best chance on Tuesday evening. It will be noticeably cooler though, with highs only reaching the upper 70s!
Lots of folks in town for the World Junior Track and Field Championships starting Tuesday and it’ll be cool for the runners but you might need to find some cover in the stands. Things look to heat up again by the end of the week. That will likely be something those walking in the Eugene Marathon need to pay attention to. Right now, we could see mid to upper 80s by early afternoon on Sunday.
Have a great weekend!
