Overall, minor impacts from the weather are expected this week. Following a foggy start to Sunday, a weak front will bring light rain to areas along/west of the Cascades later Sunday with snow levels remaining above major passes. Dry conditions are expected for the first half of the week, though a warm front could bring some light rain to areas north of Roseburg/North Bend late Tuesday into Wednesday. Another weak front moves inland on Thanksgiving Day, bringing light rain to areas west of the Cascades with high snow levels. Showers taper off for northern areas early Friday, with dry conditions then expected through Saturday. There’s some chance for impactful weather on Sunday with models split on the overall pattern. About 65% of the ensemble suite maintains dry conditions with areas of valley fog, while the other 35% brings precipitation with snow levels possibly as low as 3000 ft. Stay tuned for updates!
A developing continental trough looks to bring northerly flow aloft, bringing cooler air to the area. After mild midweek weather, this pattern change may bring a few showers on Friday or Saturday as it develops. While daytime highs look to stay at seasonal norms, overnight lows could be 5 to 10 degrees below normal by Saturday night/Sunday morning and Sunday night/Monday morning. These temperatures could affect plants and animals or untreated outdoor infrastructure. Additionally, local frost/freeze conditions may create hazardous travel conditions. Please be aware of these possibilities and use extra care when appropriate.
