Long Range Air Quality Outlook Discussion

Long Range Outlook for the week of May 26

A stalled frontal boundary to the south of Indiana will continue today to bring showers and possibly a few thunderstorms to southern Indiana. This boundary will slowly lift northward through midweek bringing chances for showers and thunderstorms to central Indiana as well by midweek. By early Thursday a dry backdoor cold front will move over the state and push the frontal boundary well south of the state. High pressure will build in for the rest of the work week. Highs will be in the upper 70s to around 80 for the work week.

There’s "Unhealthy for Sensitive Groups" (USG) concerns for the northwest portion of the state for tomorrow. The smoke models show no impact from wildfire smoke over the next couple of days, consistent with recent conditions. A significant source of wildfire smoke right now, as indicated by the models, is in the southern and far northern United States, but neither model shows an impact from these plumes reaching Indiana.
