There’s a chance of storms again Tuesday and Wednesday.

Forecast
FLOOD WATCH UNTIL MIDNIGHT
OVERNIGHT: Lingering showers
Lows: 68-75
Winds: Northeast 5 mph
Thunderstorm chances will continue through 9 p.m. with rain chances decreasing by, or shortly after, midnight. It will remain cloudy and humid overnight with low temperatures falling into the upper 60s in the suburbs to middle 70s downtown. Areas of patchy fog may develop, so watch for reduced visibility. Pavement will remain damp, so be mindful of slick surfaces.
TUESDAY: Mostly cloudy, chance of showers and storms
Highs: 82-85
Winds: Northeast 5-10 mph
The active weather pattern rolls on with clouds, high humidity, and rain/storm chances. Afternoon high temperatures will be cooler-than-average with highs in the 80s. Showers and storms will likely develop at some point throughout the day, but there will also be a lot of dry time for your outdoor activities. Humidity levels will remain high, so the stickiness factor will be in play. With the high humidity, any storms that develop could contain heavy rainfall that could lead to isolated flash flooding.
WEDNESDAY: Partly sunny, chance for storms
Highs: 82-85
Winds: Northeast 5-10 mph
The rinse and repeat weather pattern rolls on with high humidity, more clouds than sun, and chances for showers and storms at any point throughout the day. There is a slightly lower chance for rain midweek, so that may bode better for your outdoor plans. With the continued high humidity and chance for slow-moving storms, isolated instances of flash flooding will be possible.
THURSDAY: Chance showers and storms
Highs: Upper 80s
Winds: South 5-10 mph
Temperatures begin to climb again with highs approaching 90 under a mix of sun and clouds. A typical summertime pattern develops with scattered afternoon and evening thunderstorms. Not everyone will see rain, but any storm will be capable of brief heavy downpours and lightning.
FRIDAY: Scattered showers, storms possible
Highs: Near 90
Winds: Southwest 5-10 mph
Warm and more humid conditions continue with afternoon highs around 90. Expect a mix of sun and clouds followed by scattered late-day showers and thunderstorms. Storms should remain fairly typical for July, but locally heavy rain and gusty winds will once again be possible.
