FORECAST SUMMARY: Monday, January 12, 2026 through Friday, January 16, 2026
PM-2.5: 24-hour average Fine Particulate concentrations are expected to be mostly Good (AQI Green) to Low Moderate (AQI Yellow) throughout the forecast period.
FORECAST DISCUSSION
AQI values begin the week in the Good category. Monday may prove to be the mildest day of the forecast period. A short wave of low pressure will exit the region followed by a short-duration ridge of high pressure. That will be following be another short wave of low pressure, Tuesday morning, with rain under warmer 40 degree temperatures as we remain under a continental air mass.
January temperatures return Wednesday morning as an arctic front drops down from Canada followed by Canadian high pressure on Thursday. Expect high temperatures in the low 20’s. There does not appear to be a threat of a major snow event during this forecast period although some snow may accompany the arctic front passage on Wednesday. Lake effect snow should be minimized with the wind fetch behind that front being more north-northeast than west-northwest.
In terms of Air Quality, Good Air Quality should persist with some scattered Low Moderates in the early part of the week.
EXTENDED FORECAST:
Air Quality is expected to remain mostly Good entering the upcoming weekend.
