Meteorologist Melissa Frey’s Forecast Discussion:
A warm front is making its way through western Oregon Sunday. This will give us overcast skies, rain showers and much warmer temperatures. Showers will continue off and on for all of western Oregon through the evening. The snow level is above the passes and highs in the valley will return to the mid 50s. The winds will also pick up Sunday afternoon with gusts between 30 and 40 mph.
This storm will also include a cold front which will bring in winter weather with it. Temperatures will start to fall Sunday night and the passes will likely see snow starting Monday midday, with 6-12″ by Tuesday morning. The freezing level will drop from 6,500′ Monday morning to 3,500′ Monday afternoon and 2,000′ Monday night. The lower foothills and Coast Range will likely see some snow Monday evening through the night, but it’s still questionable for the valley. With storms like this it’s all about timing, and whether or not there will still be any moisture available once the cold air gets to the valley. The freezing level will likely get close to sea level early Tuesday morning, but this is also the same time that the showers will taper off. So a quick dusting is the most we could see, but even that is a slight chance.
After Tuesday it’s back to dry weather and we stay that way through the end of the week, but it will be very cold! Lows will be in the teens and 20s for the valley with highs only in the low 30s.
Have a great rest of your weekend,
