Stiff southerly breezes will continue throughout the forecast period as a low-pressure system stays on the Canadian prairies.  Mostly cloudy skies limit ozone production, and scattered showers will wash pollution effectively from the air through the weekend.  After Monday, an upper-level ridge will support higher temperatures, mostly sunny skies, and only isolated rain showers.  This combination favors an increase in ozone, but the southerly winds will bring plenty of humidity and perhaps a small amount of Saharan dust toward the end of next week.  Scattered showers, however, may redevelop late next week.
