03/04/2019 Forecast Update
FORECAST SUMMARY:
Monday, March 4th, 2019 through Monday, March 11th, 2019
PM-2.5: 24-hour Fine Particulate concentrations will be generally Good to Low Moderate through the forecast period.
FORECAST DISCUSSION
The first half of the work week will stay Good for Air Quality as a low pressure system in Canada sends a series of short-wave low pressure systems through the region. Each of those short-waves will be followed by reinforcing Arctic air. The last of these short-waves should be through Wednesday night.
High pressure moves into the region for the latter half of the work week. Warmer temperatures and calmer winds will likely cause Moderate conditions to creep in during Thursday and lasting into the weekend. Stronger southerly winds will occur during Saturday as a deep low pressure system approaches the region. That system should pass through Sunday afternoon followed by northwest winds and another shot of cold air. That will put us back into Good Air Quality.
EXTENDED FORECAST:
Air Quality is expected to remain mostly Good going into the next work week.
