High pressure is providing light winds with warmer air aloft acting as a lid over cooler/colder air near the surface. This can trap pollutants close the ground, especially the valleys, and result in degraded air quality. An air stagnation advisory is in effect.
High pressure will provide dry weather through at least Tuesday of next week. However, signs are pointing to a pattern change with clouds returning around mid next week along with a chance of rain. Rain will likely arrive at the coast Tuesday night, then could spread inland across much of the remainder of the area Wednesday into Thanksgiving Day. There could also be snow in the mountains. It’s been a while since we’ve seen significant precipitation across SW Oregon and northern California and, as of now, details with respect to when, how much and snow levels are uncertain. So, if you’re traveling for the Thanksgiving holiday, keep checking back for updates and at least make plans for potential incoming inclement weather next week.
