FORECAST SUMMARY: Monday, December 12, 2022, through Monday, December 19, 2022
PM-2.5: 24-hour average Fine Particulate will range from Good to Moderate through the forecast period.
FORECAST DISCUSSION:
Weather conditions will be relatively quiet early this week with surface high pressure positioned well north of the region. This does not last, however, as a more active pattern develops by mid-week. Before then, lighter easterly winds should keep fine particulate at bay. Pollution readings ranging from upper Good to low Moderate through Tuesday are expected. Winds turn a bit more southeasterly and moisture increases bringing in chances for precipitation Wednesday. Temperature ranges across the state bring with it ranges of precipitation types; anticipate mostly rain across the south and snow further north. Wind speeds increase as the storm system develops which should keep fine particulate from increasing much past upper Good.
EXTENDED FORECAST:
Extended models show cold conditions for the week prior to Christmas and there also looks to be a few possibilities for snow showers. Pollution levels into next week should stay consistent in the upper Good to low Moderate range.
