Storms Tonight and Heat Tomorrow
Severe weather is on the horizon for the Chicago area as meteorologist Mary Kay Kle reports an intensifying storm threat. Currently affecting parts of Iowa and Southwest Wisconsin, the storm system is expected to reach the western suburbs of Chicago around sunset, intensifying between 8:00 p.m. and 10:00 p.m. The severe weather could last until 1:00 a.m., bringing torrential rainfall, high winds, hail, and potential tornadoes.
Flooding and High Winds Expected
With the soil already saturated from recent rainfall of 2 to 4 inches, flooding is likely. High winds and hail are also predicted, adding to the severe weather threat. A severe thunderstorm watch is in effect until 1:00 a.m., including areas in Lake County and Northwest Indiana.
Tropical Air Fuels Storms
The storms are moving into an environment ripe for development, with tropical air contributing to the intensity. Current dew point readings are as high as 82 degrees in Sterling and 79 in Ottawa. Temperatures across the region are also high, with Jefferson Park at 88 degrees and Lincoln Park at 87 degrees, creating a favorable environment for storm formation.
Timing of the Storms
The line of thunderstorms is expected to start moving into the Chicago area between 8:00 p.m. and 9:00 p.m., bringing heavy rains to Cook County by 10:00 p.m. and forming a squall line by midnight, potentially affecting Northwest Indiana until 1:00 a.m.
Heat Wave to Follow
After a dry start to the day tomorrow, temperatures are expected to soar, with a feels-like temperature between 100 and 106 degrees. Another round of severe thunderstorms is anticipated from sunset to midnight, with the Chicago area being elevated to a level three out of five for severe weather hazards.
Relief in Sight
The severe weather is expected to subside starting Wednesday, bringing cooler lake breezes and quiet weather for the rest of the week and into the next weekend.
