Forecast Discussion

Forecast Valid: Sunday, June 13, 2021

Today's Air Quality Conditions: Ozone and particle pollution readings are in the Code Green range statewide thus far this afternoon. For a display of the most recent air quality conditions throughout the remainder of this afternoon, please visit the US EPA's AIRNOW web site.

General Forecast Discussion: Partial clearing is expected tomorrow as an area of low pressure builds offshore, with winds becoming northeasterly. Isolated showers and thunderstorms will be possible, but should be lesser in coverage than previous days. Typically lower weekend emissions should also help to keep ozone and particle pollution readings in the Code Green range statewide.

Outlook: Drier weather is expected to start the coming week, with partly cloudy skies and temperatures warming into the lower 90s during the daytime over the Piedmont and points east. A frontal boundary is expected to move through the state on Tuesday with a brief round of scattered showers and thunderstorms, with partly cloudy skies otherwise expected. Ozone readings building into the Code Yellow range will be a possibility over the Ridge Tops as well as the Piedmont, with lower readings in the Code Green range elsewhere. Particle pollution readings are expected to build into the upper Code Green range statewide Monday into Tuesday, with localized Code Yellow readings possible over the Piedmont Tuesday.
