Timeline: How severe weather threat will evolve in Chicago area this week

After storms rumbled through the Chicago area Monday and into Tuesday morning, more nasty weather could be in the offing.

According to the Storm Prediction Center, a wide swath of the area will be at an “enhanced” risk of severe weather on Tuesday, with strong tornadoes and large hail possible in various locations.

    The NBC 5 Storm Team forecast indicates that the bulk of the severe weather could arrive Tuesday afternoon and into the evening, but here is a full timeline of what we can expect on Tuesday and into the days ahead.

    Tuesday Afternoon

    Temperatures across the Chicago area feel positively summery, with readings in the low-80s and dew points soaring into the 60s, according to the NBC 5 Storm Team.

    Those conditions will be ripe for the development of thunderstorms, and the first wave of storms could potentially occur in areas south of Interstate 80 on Tuesday afternoon, according to forecast models.

    All manner of severe weather threats are on the table for storms that develop, including isolated tornadoes, large hail, gusty winds and heavy rain, which could lead to flooding concerns in areas that were hard hit by rain on Monday.

    Areas south of Interstate 80 in Illinois and into Indiana are at a “slight risk” of severe weather, the second of five levels of risk used by the SPC.

    Tuesday Evening

    The main event for severe weather could occur between 6-to-11 p.m., with the epicenter potentially being the Chicago area north of Interstate 80.

    That area is at an “enhanced” risk of severe weather Tuesday night and into Wednesday morning, and forecasters are warning of the possibility of “very large” hail of two inches or more in diameter, and the possibility of strong tornadoes, some of which could be EF-2 or higher on the Enhanced Fujita scale.

    Those storms are expected to develop on Tuesday evening and sweep across the area, and in addition to the threat of tornadoes and hail damaging wind gusts and heavy rain could occur.

    Wednesday Morning

    Rain could persist into the early morning hours Wednesday, with scattered showers and embedded thunderstorms continuing until almost daybreak in some locations, according to forecast models.

    Isolated storms may be severe, but another threat will emerge later in the day.

    Wednesday Afternoon

    Most of the Chicago area is at a “marginal” risk of severe weather Wednesday, with gusty winds and heavy rain again the biggest threats.

    Those severe storms would be more isolated in nature, but any rain that falls could add to the risk of localized flooding, according to forecast models.

    Thursday

    More rain is possible on Thursday in the Chicago area, with scattered showers expected in the morning hours before things finally start to dry out later in the day.

    High temperatures should be pleasant on Thursday, with readings in the 70s, according to forecast models

    Friday

    Friday could see yet another round of strong-to-severe thunderstorms late in the day, with highs in the 80s and humid conditions expected, according to forecast models.

    Saturday

    Storms that accompany an approaching cold front will continue to fire into the morning hours Saturday, with temperatures dropping throughout the day after the front passes through.

    By Sunday, conditions will have calmed down, but temperatures will have dropped into the 50s for highs, according to the NBC 5 Storm Team.
