FORECAST SUMMARY:
Monday, November 23rd, 2020 through Monday, November 30th, 2020
PM-2.5: 24-hour average Fine Particulate concentrations will also be mostly Good with occasional Moderate during cold morning, calm wind inversions.
FORECAST DISCUSSION
A series of fronts passing through the region during the holiday week should keep the atmosphere well mixed resulting in mostly Good Air Quality.
The first front will pass through during Monday and clean out any residual high particulates we saw during the weekend when we experienced strong morning inversions. That will be followed by a short period of high pressure then southerly winds before the next low pressure system early Thursday morning. Air Quality should be generally good with some isolated Low Moderate readings in urban areas.
The Thursday cleanout will be followed by another fast-moving front during Friday. That will lead to cooler weather during the weekend and another dry cold front late Sunday.
EXTENDED FORECAST:
Air Quality should be mostly Good going into next week.
