Yesterday afternoon saw a minor short lived spike in PM10 levels associated with thunderstorm winds but it was less than the routine morning spike driven by local industrial and commercial activities. But, the 24 hour average remained in the Good category. That pattern is expected to continue each day through through Sunday along with slight chances of precipitation (less storm activity Friday).
