METEOROLOGIST MELISSA FREY’S FORECAST DISCUSSION:
It may be chilly and it may be foggy, but it is not raining and today is the only day we’ll be able to stay that this week.
The ridge of high pressure that has been keeping us dry since Tuesday is now moving east. The jet stream is moving south which means, the tracks for the storm train will be headed right into western Oregon. Thursday will be dry with sun breaks by the afternoon. Highs will stay in the mid 60s. By Thursday night we’ll start to see the clouds out ahead of the next storm moving in.
This storm is a cold front which will bring rain to western Oregon before sunrise Friday. We’ll see scattered showers for most of the day and highs in the low to mid 60s. Saturday we’ll be in between storms, but we’ll continue to see isolated showers with highs down into the mid to upper 50s.
Sunday is looking pretty soggy with highs dropping to about 55 degrees.
As the jet stream moves south, we’ll see cooler air moving in with each day. The freezing level will likely drop to around 4,000 feet by Sunday morning, where it will stay through at least Wednesday. This means the Cascade passes could see their first snow of the season.
Have a great Thursday and enjoy this last dry day,
-Meteorologist Melissa Frey
