It appears we’ll get in 200 laps, but the “window of opportunity” for dry weather over the Indianapolis Motor Speedway gradually closes down after 3pm. The ragged, eastern fringe of an area of showers in western Indiana approaches the Indy metro by 4pm, and sprinkles/shower chances increase the rest of the day. If you’re at the track or have evening grilling plans expect some rain to move across the I-70 corridor.
Rain this evening should be generally light, and similar to Saturday evening. However, deeper atmospheric moisture and a warm front will trigger heavier storms on Memorial Day. Though I don’t anticipate severe weather, there will definitely be less dry time to get outside Monday. High heat and humidity build in after the passage of a warm front Monday night… setting the stage for a prolonged period of above normal temperatures. Highs Tuesday jump into the 80s with hazy sun, and near 90 a few days during the middle of the week. The next “best” chance of rain after Monday is next weekend as a frontal system stalls around the region. Have a great evening and holiday tomorrow – Sean Ash
