Forecast Discussion: Updated Tuesday, October 21, 2014 10:15 a.m. Quiet weather is in store for the area over the next several days as high pressure builds into the area. A Pacific Northwest trough will move through the area late on Sunday/Monday and bring breezy to perhaps windy conditions. We’ll have to keep an eye on this developing storm system to see if the winds will be strong enough to increase the PM10 AQI levels towards health watch or high pollution advisory criteria.
