Forecast Discussion

Date: Wednesday, January 22, 2020

Forecast Valid: Thursday, January 23, 2020

Today's Air Quality Conditions: Particle pollution readings are in the Code Green range statewide today. 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: Tomorrow, cold high pressure will build over the Mid-Atlantic and continue to deliver a cool, dry and clean air mass into the region that should hold air quality levels in the mid to upper Code Green range.

Outlook: Friday, an approaching cold front will bring rain to the region. Combined with weak onshore flow, particle pollution levels should hold predominantly in the upper Code Green range. On Saturday, the front will have crossed the state and a colder, drier, and cleaner air mass will again move into the region from the north and west and air quality levels should lower back into the Code Green range.
