The highest AQ index in Oklahoma (as of 17:00 CST) is currently the Miami area. Particle Pollution (PM2.5) is measuring at 72 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Particle Pollution (PM2.5) will be in the McAlester area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Bitter cold temperatures are expected to persist throughout the week as Oklahoma sits under an area of high pressure. Recent widespread snow cover will lead to temperature inversions through Thursday, trapping particulates close to the surface. This will lead to higher particulate levels during the first half of the week, gradually clearing out as the temperature inversions become lest prominent.
