Chicago residents are bracing for a day of active weather, as the forecast calls for two separate waves of showers and storms throughout Tuesday. This unsettled pattern is accompanied by a notable temperature shift, with readings expected to plummet by as much as 30 degrees.

Tuesday's Storm System Breakdown

Morning Showers and Initial Activity

As of early Tuesday morning, Live Doppler 5 radar indicated that a line of showers and lightning was already moving across counties situated to the north and west of the city. Meteorologist Roman noted that this initial period of scattered rain is anticipated to persist until approximately 12 p.m.

During this first wave, there is a possibility of localized heavy downpours impacting various parts of the Chicago area.

Afternoon Cold Front Triggers Second Wave

The second, potentially more significant, round of rain and storms is scheduled to arrive later in the afternoon and continue into the evening hours. This timing coincides with the passage of a cold front, which is the primary trigger for the incoming weather change.

This frontal passage will cause temperatures to drop sharply, moving from the 70-degree range down into the 40s. The afternoon and evening hours are currently favored for higher coverage of storm activity.

Severe Weather Potential and Hazards

Risk Assessment for Stronger Storms

Meteorologist Roman indicated that one or two of the developing storms later in the day could reach a stronger intensity. Consequently, a significant portion of the greater Chicago area is currently under a "slight" risk designation for severe weather.

Roman detailed the potential hazards associated with any developing storms, whether in the morning or afternoon. "Really, any storms that we do have not only this morning but this afternoon could contain lightning, heavy rain, gusty winds and small, pea-sized hail," he stated.

Factors Influencing Storm Strength

The intensity of the afternoon storms may depend on the morning activity. Roman explained that the regeneration of storms later in the day is contingent upon the showers and storms that pass through earlier. The arrival of the cold front serves as the crucial mechanism to fuel this later development.

Looking Ahead: Midweek Weather Outlook

The period of active weather is set to continue beyond Tuesday. Daily chances for rain and storms remain in the forecast for both Wednesday and Thursday.

Temperatures are expected to remain cool on Wednesday, staying in the 40s. By Thursday, however, a rebound is anticipated, with readings expected to climb back into the 60s.
