A Knozone Action Day has been declared for Indianapolis, IN, on Wednesday, Jun 7 and Thursday, Jun 8, 2023.
Today will be a little hazy from wildfires to the north, otherwise expect a pleasant day.
Temperatures all this week will be on the cooler side than we’ve experienced as of late.
There will be a small chance for rain on Wednesday, but a dry forecast for the rest of the period. Partly sunny with haze today and highs around 80. Northeast winds will be at 5 to 10 mph.
Dew points will be in the upper 30s and afternoon minimum relative humidities no lower than 23%. For tomorrow (Tuesday) mostly sunny with highs in the lower 80s.
Light north northwest winds in the morning will increase to 5 to 10 mph.
Dew points will be in the upper 40s and afternoon minimum relative humidities no lower than 30%. Wednesday be partly sunny with a small chance for showers and highs around 80.
East northeast winds will be 5 to 10 mph.
Dew points will be around the lower 40s and afternoon minimum relative humidities no lower than 30%.
Forecast a bit of a borderline situation for Ozone Air Quality between USG (Unhealthy for Sensitive Groups) and Moderate categories.
Thinking is that this slowly sinking backdoor cold front will prevent conditions from getting worse than Moderate, despite the column being somewhat still dry.
Clouds will also be around the area, and temperatures are not as hot as they have been.
So even with this low humidity thinking going Moderate for the area makes the most sense at this time.
Moderate also makes the most sense for PM2.5 as well because of the aforementioned reasons and that there shouldn’t be any large scale plumes from the fires up north that will impact the area.
