Drenching downpours and thunderstorms late tonight; Hot open to Autumn

FRIDAY STORMS QUICKLY DEPART

A gusty line of storms has departed NE at 5:30 PM after bringing blinding rainfall and strong wind gusts.

Guardian radar detected a potential gust to near 50 mph and it verified. I'm posting image below. The Airport reported a gust of 50 mph and it was enough to snap a few tress and down power lines. Numerous power outages include traffic lights for Friday evening commuters making for a slow go.

A WARM SEPTEMBER 16th

Temperatures jumped into the mid 80s along with high levels of humidity before the storms arrived Friday. The high of 87° in Indianapolis is the warmest for a September 16th in 22 years (1994).

The fast moving storms are quickly departing and a large gap of rain-free time is developing in time for area High School Football games. Showers and storms will spread northeast form south Illinois later tonight and into Saturday morning. Rain chances rise again approaching the 12 AM time frame.

GAPS BETWEEN DOWNPOURS SATURDAY

We will get dry time Saturday after the early downpours and scattered t-storms. An approaching cold front will ignite new showers and storms in the afternoon but plan on extended rain-free hours. More dry time develops as the front settles south Saturday night.
