Spotty showers returned to Central Indiana on Saturday evening thanks to stationary boundary stalled out across the state. This boundary will be the focus for more rounds of rainfall over the holiday weekend so be sure to keep checking the radar, especially if you’ll be spending plenty of time outside.
TONIGHT: Scattered showers continue across the state this evening. This rainfall activity will become more isolated in the overnight hours. What we continue to watch is this wave coming in from Illinois. The air is relatively dry north of I-74 this evening so it will take a while for the atmosphere to get moist enough to support any type of steady shower. Little to no lightning is expected tonight.
SUNDAY/RACE DAY: Race fans, you know we have a love/hate relationship with the weather for the Indianapolis 500. Indianapolis has seen severe weather, sweltering heat, pouring rain and chilly temperatures. Here’s the good news, no severe weather is expected tomorrow. But it does look like we’ll be watching the radar closely tomorrow as a warm front lifts through the state, which will keep in the threat for rainfall during the day. Does this mean it’s going to rain all day? Likely not, but spotty showers will be possible for most of the day.
It looks like our best chance for rain tomorrow morning is in the southwest part of the state. Many of the weather models keep the metro dry tomorrow morning but we aren’t too far off from the cutoff, so don’t rule some sprinkles or light showers out. After that, rainfall may take a small break and this hopefully leads to a dry start to the race. But it’s all dependent on what forms in Illinois and then travels into our state. So if you are watching the radar tomorrow, keep your eyes to the west. Spotty showers remain possible during the afternoon with widespread showers Sunday evening. This all being said, there will be several dry hours to enjoy! As for temperatures tomorrow, it will be cool again with highs only in the mid 60s. That leaves us 10 degrees below normal for this time of year and 25 degrees colder than last years Indy 500! The last time the Indy 500 had temperatures in the mid 60s was back in 2003 when the high only hit 65°F. That following year, 2004, was the year that Speedway was under a tornado warning and an F2 tornado touched down in the southern part of Indianapolis. http://www.crh.noaa.gov/ind/?n=2004tor_tracks
MEMORIAL DAY: The threat of rain will linger again on Monday. Scattered showers and thunderstorms are expected throughout the day as waves of moisture continue to track along the warm front. Obviously, this is a big day for outdoor activities. Please remember, if you hear thunder, head inside immediately. If you plan on being outside and away from a TV during the day, have the Fox 59 Weather Authority app on your smart phone. Temperatures will jump up on Monday since we’ll be under the warm front by the afternoon hours. This will lead to temperatures in the mid to upper 70s. This finally leads to normal temperatures for 1 day before hot temperatures and higher humidity levels return.
