Forecast Discussion: We will have to deal with a few more days of warm and stagnant conditions before a fairly significant cool down and breezy winds take place over the weekend. By Sunday, high temperatures may not even hit 80 degrees! The storm system that is being watched is currently over 2,000 miles away near Alaska and is projected by models to quickly slide down the West Coast over the next 72 hours or so. The associated cold front should bring stronger southwesterly winds (gusting over 20 mph at times) to the area by Saturday, but even Friday afternoon could see an increase in wind speeds as the storm draws nearer. No dust issues, however, are anticipated at this time. Unfortunately, moisture at the surface would be very limited making rain chances at this point minimal, but periods of clouds can still be expected beginning late Thursday, which would help lower ozone a bit. Otherwise, there should be no major changes to current air quality trends through Friday. Check back tomorrow for the latest. Until then, have a good day! -J.Malloy
