An outflow boundary, leftover from morning severe weather in northern Illinois, may trigger additional storms over east central Illinois by mid afternoon. Damaging winds are the main concern if these storms form.
A thunderstorm complex will work through the northern half of Illinois today with a conditional threat storms extend southward into central parts of the state. If they do, damaging wind gusts 75+ mph are the primary hazard. Additional storms are possible later tonight, though will be lower in coverage and intensity. Stay weather aware today!
Seasonally hot and humid weather continues through midweek with peak heat indices between 100-105° each afternoon. Protect yourself from the heat by staying hydrated and limiting time outdoors.
A slow moving front will shift south into the area by midweek, bringing the chance for isolated to scattered severe storms Wednesday and Thursday.
A Severe Thunderstorm Watch has been issued for areas along and north of I-74 through 2 pm. Severe storms, capable of producing winds over 70 mph, are expected to track across northern Illinois through midday. Monitor weather conditions closely this morning if you are in this area.
