Meteorologist Melissa Frey’s Forecast Discussion:
The ridge of high pressure that was keeping us dry and warm all week as moved east. The jet stream is dropping south and that means any storms developing in the Pacific Ocean will be headed right for western Oregon. There’s only one storm on the horizon now, but it will stick with us for a few days.
The edge of this storm is just off shore and has already begun to spread clouds across the state. We’ll eventually start to see light rain, but not until the late afternoon for the Coast and later in the evening for the Valley. Highs Monday will stay in the mid 40s in the Valley and mid 50s for the Umpqua Basin and Coast. The freezing level started out at about 9,000′ but will drop to 6,000′ tonight. It’ll stay above the passes through Tuesday night, but likely drop to about 3,500′ by Wednesday night. This means just plain rain at the passes initially, but gradually it’ll mix with more snow over the next 48 hours.
Light rain will linger through Tuesday with scattered showers through Wednesday. This storm will wrap Wednesday, but from then through the weekend we’ll stay in an “on-shore” pattern, meaning there may be additional small disturbances that keep us mostly cloudy and we may see a few light showers from time to time. Highs will stay in the mid to upper 40s all week.
Have a great day!
