Southerly flow will resume today and bring back a maritime tropical air mass with Saharan dust.  Scattered rain showers and clouds will impede ozone formation.  The heat dome will intensify over the southern Great Plains and the southwestern deserts through next week, but southerly flow will continue to bring abundant Saharan dust at least into the middle of August.  Under mostly sunny skies, ozone also may reach the moderate category near and downwind of major cities.
