Not much change in the weather is expected this week with stagnant air continuing which will impact air quality for low lying valleys in southern Oregon, you can find current air quality levels on the weather homepage under ‘weather links.’ Fog will gradually lift and break during the afternoon hours each day which is when temperatures will quickly climb, but there will only be an hour or two each afternoon when temperatures climb out of the 30s in west side valleys then it will drop quickly once the sunsets. This means that west side valleys will continue to be cool and cloudy for the most part and the timing of fog clearing will determine our high temperatures each day. Outside the fog temperatures will be mild and sunny skies will continue.
A trough is going to slide over the ridge Wednesday bringing increased clouds to the area and only a slight chance for showers, but I’m holding off on adding any precipitation anywhere due to the strength of the ridge and the weakness of the system riding over it. High pressure strengthens again by the weekend and I wouldn’t be surprised if we see the Air Stagnation Advisory get extended yet again. Even though were not in fire season, keep fire safety in mind as we are in a Severe drought.
Thanks for logging on and have a great evening!
