Little change is expected in our forecast through the week which means valley fog will persist and will dense in many locations with gradual lifting and breaking through the day. A weak low pressure is going to slide north along the ridge late Tuesday and dip south and east of our region Wednesday then rotate offshore through the week as it becomes cut-off from the jetstream. This will bring a chance for some drizzle at the coast Wednesday and increasing clouds across the region, while valleys could see a break in the stagnant air with clearer skies and air, but this break will be brief. High pressure builds back in for the second half of the week but with the cut-off low offshore will bring just a few more high clouds across the area through the week, but still mostly sunny skies.
The Chetco Effect will return to the Brookings area and cities along the Chetco River on Thursday and a bit weaker but still present Friday. The cut-off low will start to move inland early next week and this could bring our next chance for showers to the region; but being a week away and since cut-off lows are not handled well by weather models I’m holing off on adding widespread showers to the region.
Thanks for logging on and have a great evening!
