Weather Synopsis for Wednesday night through Sunday
Cold temperatures and windy conditions continue to dominate the weather headlines for the area. You may find temperatures in the teens and even single digits in most mountain locations. A deep trough over the area continues to draw cold air into the region from Canada. This will keep freezing levels well below trailhead locations. Moderate to strong easterly winds associated with this trough may impact the area even at lower elevations. Winds should begin to decrease during the day on Thursday. When temperatures are this cold, you could encounter wind chill values well below zero.
We expect some snow showers to continue in areas east of the Cascade crest Wednesday night into Thursday morning as a low-pressure system shifts to our south. You are most likely to find showers where cold east winds push moisture up onto the east and northeast slopes of the range especially in areas like Mt Hood, Blewett Pass, and Mission Ridge. These upslope snow events are difficult to predict and you're likely to encounter quite a bit of variability even over short distances. Areas on and west of the Cascade crest should experience general dry weather during this time frame.
Look for cold and dry conditions over most locations by mid-day Thursday. This pattern should hang with us into the start of the weekend.
