StormTracker 9 Forecast: Rain and snow will affect Thanksgiving travel

Our StormTracker 9 meteorologists are tracking sunshine and dry conditions through first half of weekend, then showers and mountain snow heading into next week.

Posted: Nov 22, 2019 10:23 AM

EUGENE, Ore. -- It was a sunny, cold start on Friday with high pressure locked in place.

This will remain in place through Saturday due to what is called an Omega Block. An Omega Block is when the jet stream resembles the Greek letter Omega. The region under the Omega Block experiences dry, sunny weather, while those to the east and west will see more rain showers and clouds. Oregon is currently under the block, hence the dry, sunny conditions we are experiencing.

Fast Forecast:

Friday: Morning frost & patchy fog. Sunny. Highs in low 50s
Saturday: Morning frost & patchy fog. Partly sunny. Highs in low 50s
Sunday: Iso. showers. Snow level 6,500 ft, dropping to 3,500 ft overnight. Highs in low 50s
Monday: Showers. Snow level 3,000 ft, dropping to 2,500 ft overnight. Highs in mid 40s
Tuesday: Showers. Snow level 2,000 ft, raising to 2,500 ft during afternoon. Highs in low 40s
Wednesday: Partly sunny w/ iso. showers. Snow level 2,000 ft. Highs in low 40s
Thanksgiving: Mostly sunny w/ slight chance. Highs in low 40s

After the fog lifts on Friday morning, expect highs to climb into the low 50s with sunshine. Friday night will be another cold night with temperatures dropping to near freezing. With that said, expect more widespread frost and areas of fog heading into Saturday morning.

The pattern turns wetter and cooler starting on Sunday, as a series of fronts and low-pressure systems traverse across the region. The first front will likely bring light showers on Sunday from north to south. Snow level will likely be around 6,500 feet during the day and 3,500 feet overnight.

Behind the front, colder air will begin to funnel into the Pacific Northwest, along with another rain event on Monday. As the rain arrives, cold air will allow snow levels to drop below the Cascade passes. This is something you should be prepared for next week ahead of the Thanksgiving holiday. Monday’s snow level is expected to be around 3,000 feet.

Beyond Monday, there is a large uncertainty in the models. Models take Tuesday’s system somewhere between Vancouver Island and San Francisco. With that said, no single model solution should be trusted at this time. But given the cold air pushing south, this system will need to be watched for the potential for low-elevation snow on the north side of the storm.

The current forecast is trending colder, which will drop snow levels to around 2,000 feet on Tuesday and between 1,000 to 1,500 feet on Wednesday. Snow is not expected to fall to the valley floor at this time.
