A weak offshore flow is now beginning to develop across the region. This is due to a new air mass that is allowing for a thermal heat low to form. The counter clockwise flow around this is bringing that offshore flow, along with smoke and haze to Curry County. This pattern will continue into the weekend and smoke will continue to migrate west near Brookings and Gold Beach into Saturday.
By Saturday morning a northeast wind will bring deteriorating air quality to the Illinois Valley, and improve conditions to the Rogue Valley, the mountains and Klamath Basin. Overall, improving sky conditions will be the case for inland areas, with more smoke traveling west to the Coast. By the afternoon it will spread further inland but not like the thick smoke of this past week. Sunday though will bring an onshore wind, as opposed to the currently present offshore flow. This then will move the smoke back into the Rogue Valley, Cascades and Klamath Basin.
Expect a mix of sun and clouds along the Coastline this weekend, with the offshore flow bringing warmer temperatures to Brookings Saturday afternoon, and cooler temperatures Sunday. Inland, we’ll see sunny skies but hazy conditions. By next week, thunderstorms could possibly move back into the East Side.
