PM-2.5: 24-hour Fine Particulate concentrations will be mostly Good with some Low Moderate through the forecast period.
After a pleasant weekend, which actually felt a bit like Spring, we will be returning to cooler weather and maybe even a touch of snow during midweek.
The work week begins with west-northwest winds and Good Air Quality. We will see a brief turn to southwest winds as a small low pressure system passes to our north, Monday night, but see winds shift back to the northwest during Tuesday. Air Quality should remain mostly Good.
The most interesting feature of this week’s weather begins making itself known late Wednesday as a strong low pressure center comes out of Colorado and presses northeastward. We will see surface winds shift to the east in advance of its arrival. This is a deep low and winds will become brisker as it approaches. These brisk winds will briefly turn to the south, Thursday night, as the center of the low enters the Great Lakes region. With the brisk winds, I don’t expect issue with Air Quality.
The low pressure center will pass Friday night, and return the region back to a clean, northwest air flow for Friday and early Saturday. I anticipate light winds during most of the weekend so some areas may see a creep into the Low Moderate range.
Temperatures are projected to be back into the 60’s by early next week and that could spawn some Low Moderate readings.
Air Quality is expected to remain mostly Good to Low Moderate going into the next work week.
