A low pressure system will develop off the Oregon coast Friday that should bring a warming trend to the Inland Northwest this weekend.
High temperatures in the mid-70s and 80s should jump into the 80s and low-90s by Saturday, said Jeremy Wolf, a forecaster with the National Weather Service.
Isolated showers and thunderstorms are expected in the mountains today through Saturday.
As for Sunday, it’s unclear what will happen to that low pressure system as it moves east. However, temperatures should drop into the 80s, and the region will see an increased chance of showers, thunderstorms and lightning Sunday night and Monday, Wolf said.
The low temperatures through the weekend are projected to be in the mid- to upper 50s.
