Warmer but cloudy weekend should remain dry
While we don’t expect to be able to measure any rain or snow this weekend, we certainly have some concerns. Let’s start with the air quality alert for both Saturday and Sunday that has been issued. This is something that is fairly rare for Indianapolis to see during the winter. Basically a strong inversion, layer of warm air on top of cooler air at surface, will trap particulates at the surface. This could make it tough or uncomfortable to breathe for the oldest and youngest amongst us. Also those who deal with allergies or asthma may also find it difficult to breath at times. Officially we are under an orange level alert, the third tier of five, with conditions being unhealthy for sensitive groups.
The air quality alert goes through the weekend with the inversion expected to persist through this time. Cloud cover will be likely throughout the weekend. Highs will still be going up as we see a warmer air mass move in. Highs will be close to 50 degrees on Sunday and even on Monday.
While no measurable rain is expected, light mist or drizzle could occur. Thankfully temperatures should not fall below 32 degrees for the remainder of the weekend meaning we don’t have to worry about slick roads.
Timing of the next rain has been pushed back just a little bit and now looks like it will arrive after 5 pm on Monday. It will continue through the overnight hours and mostly wrap up on Tuesday morning before 8 am. Light snow may fall after the rain ends.
