Scattered showers, heavy showers and possible thunderstorms are expected to begin the weekend in the area, while colliding with the return of the Chicago Air and Water Show.
However, the timing between rain and show may work, with heavier rainfall expected to fall in the evening after the show ends, NBC 5 Storm Team said.
Most of Illinois, including the greater Chicago area, and Indiana are under “marginal” risk of severe weather Saturday, with the greatest storm coverage expected in the evening, according to the Storm Prediction Center. A “marginal” risk is the lowest level of threat on the CPS scale, behind slight, enhanced, moderate and high.
Showers could fall in the morning, with more scattered precipitation and possible thunderstorms during the day as well.
The greatest chance of severe weather is Saturday night, with heavy thunderstorms possible in the evening. According to the NWS, occasional damaging winds and lightly heavy hail will be the main threats, which added brief heavy showers that could cause flooding in some places.
If lightning is detected in the sky, NBC 5’s Brant Miller urges those outside to seek safe shelter.
Temperatures are expected to drop Saturday, with highs in the upper 70s and lows in the upper 60s, according to the National Weather Service.
The possibility of rain and thunderstorms continues on Sunday, but the chances are lower than Saturday, forecasters said.
Once the weekend is over, comfortable conditions are set to return soon after. The sun will return on Monday, with highs near 80 degrees.
After that, the region will enter a dry pattern for a few days and a slight rise in temperatures, as highs climb to the 80s.
