Here is a look at rainfall totals from July 2 to July 4, 2026. Much of this rain fell in a 48-hour period within 4 separate rounds of severe storms. Needless to say, considerable flash flooding occurred where the heaviest rain fell. #ILwx #INwx

(🧵2/2) Drier conditions return Monday, but stormy weather is forecast to return late week. Breezy onshore winds will also lead to building waves and an increased risk for rip currents at area beaches today through Monday. #ILwx #INwx

[NWS Chicago @NWSChicago]

(🧵1/2) Scattered showers and storms are expected today, especially during the afternoon and near/south of I-80. With slow storm motions, if any showers/storms stall over areas that had heavy rain the past few days then a localized flooding threat would occur. #ILwx #INwx

[NWS Chicago @NWSChicago]

There is a potential for scattered showers and slow-moving storms late tonight into Sunday morning although confidence in development is low. If storms form, some could produce locally heavy rainfall which may result in instances of renewed or additional flooding. #ILwx #INwx

[NWS Chicago @NWSChicago]

The heaviest rainfall has ended. Numerous roads remain closed or impassable. Highest rainfall amounts are estimated in central/southern Kane, NW DuPage, S DuPage and N Will Counties. Continue to heed local road closures.
Turn around, DON'T DROWN! #ILwx #INwx

[NWS Chicago @NWSChicago]
