A cooler and new air mass is now settling in. This air mass is stable, bringing dry conditions but breezy afternoon winds. The humidities are higher and this has helped crews, but the firefighting efforts are battling average wind speeds in the teens with gusts even highers. This will be the trend again into Monday, however winds are going to shift from north, northwesterly to westerly by the afternoon.
With that being said, smoke will no longer advect south but east. This will impact air quality in the mountains and the Klamath Basin. The worst readings on Sunday were in Shady Cove, Grants pass and Cave Junction. As of Sunday evening, readings in Cave Junction are exceed 200ppm, bringing them into hazardous levels for all. This means those in the Cave Junction area are advised to stay indoors or wear masks when going outside.
Into Tuesday, winds aloft are going to shift to the Southwest. This will bring moisture up from the South again, and with an incoming disturbance, instability will be on the rise. Thunderstorms will again become an issue into Wednesday and Thursday. For now, the threat remains over the Southern Oregon Cascades and the East Side. However, this will have to be watched very closely.
Temperatures all week are going to remain around seasonal values — MUCH cooler than last week. In fact, the middle of the week may even bring temperatures below normal. The Rogue Valley is forecasted to see temperatures drop into the mid 80′s Thursday afternoon!
