Monday, May13th, 2019 through Monday, May 20th, 2019
Ozone: 8-Hour average Ozone concentrations will be mostly Good through the forecast period.
PM-2.5: 24-hour average Fine Particulate concentrations will be mostly Good with some Low Moderate through the forecast period.
The cloudy, cool and wet weather observed on Monday will give way to clear skies on Tuesday as high pressure moves into the region. Winds through Tuesday will vary north to west and Air Quality should be Good.
During Wednesday, a weak front will drop down through the state. Winds will be generally southeast until the front passes then turn briefly to the northwest.
During Thursday, we will see the start of a slow warm up as winds become predominantly southwest in advance of a front over the Plaines states. Ozone will not be an issue as temperatures will not get warm enough and cloud cover will happen more often than clear skies. But Fine Particulates could creep into the Low Moderate range.
Southwest winds will persist, along with the possibility of Low Moderates, until a frontal passage late Sunday night. Rain chances increase as the front draws closer during the weekend.
Air Quality will return to Good on Monday on the back side of the front and the return of northwest winds.
Air Quality is expected to remain mostly Good going into the next work week.
