Synopsis and Discussion

Sunny skies and light winds have allowed for low code YELLOW, ozone levels, Thursday. Particle pollution is lower and upper code GREEN. High pressure centered over NC, Thursday, will slide east to take up a position off of the coast. Skies will remain clear/mostly sunny, Friday and Saturday as winds turn to a warm SW direction, and increase in strength. Under these conditions, ozone values will increase to potentially the mid code YELLOW range. The stronger winds will help to temper ozone from climbing any higher. Particle pollution looks to increase to the YELLOW category, Friday and Saturday, as well. Mostly cloudy skies are expected, Sunday, which will limit ozone to low code YELLOW while particle pollution hovers in the low code YELLOW range too (GENTRY).
