| Current conditions: An Air Quality Action Day is effect for the day Sunday. Stagnant surface winds, a moderately strong inversion, and snow cover will all act to bring fine particulate matter (PM2.5) concentrations to the code ORANGE range Sunday. Concentrations will be highest during the morning hours, and then fall some during the afternoon with a slight south wind. The day will turn out mostly cloudy with only a rain or snow shower. *** Monday’s forecast: Another weak weather system will bring a rain or snow shower later Monday or Monday evening with enough low level mixing from the south and southwest to where only moderate PM2.5 concentrations are expected. *** Extended forecast: Better air quality in the good range is expected by Tuesday, as a northwesterly flow will increase and be rather brisk in the afternoon. High pressure builds back in by Wednesday, but then a strong cold front brings rain to the area Christmas eve. A blast of very cold air will then follow for Christmas day and Saturday. Air quality should be in the good range Wednesday through Saturday.—McAuliffe |
