Forecast Discussion: FORECAST SUMMARY: Monday, October 20th, 2014 through Monday, October 27th, 2014 PM-2.5: 24-hour Fine Particulate concentrations will be Good most of the week; the best chance for Moderates will be Sunday into Monday. FORECAST DISCUSSION: A clipper storm system will track just north of the state Monday/early Tuesday bringing a chance for scattered precipitation as it moves through. Fine particulate levels will remain Good as winds become northwesterly after the system passes. High pressure builds in for mid-week with Good air quality continuing. Another weak system moves through later Thursday/early Friday. At this point is looks like the boundary will not produce any precipitation, but northerly winds will be reinforced as is passes keeping fine particulate in the Good range. EXTENDED FORECAST: Surface high pressure moves east of the state by Sunday changing winds to more of a southwesterly direction; because of this, fine particulate may reach low Moderate early next week.
