PM-2.5: 24-hour Fine Particulate concentrations will be generally Good to Low Moderate through the forecast period.
The forecast week promises to be active with several weather events impacting the state. Monday will be the best chance to see Moderate levels of fine particulates with the warmer temperatures and melting snow. A cold front will pass through the state, late Monday afternoon, and push temperatures back below the freezing level. The accompanying wind shift will also help clean the air and place us back into the Good category.
High pressure will give us a little sun on Tuesday before a series of upper air disturbances will present the threat of freezing rain Tuesday night through Wednesday. Wind patterns should be such that Good Air Quality will remain.
The next major system is anticipated to be Thursday night setting up a chilly beginning of the weekend but mostly Good Air Quality. A slight warmup late in the weekend is the next best shot at any Low Moderate conditions but that should be fairly low risk.
Air Quality is expected to remain mostly Good to Low Moderate going into the next work week.
