Chicago City is bracing for a dynamic shift in weather as Chicagoans enjoy a mostly sunny Sunday with highs in the upper 30s, a touch below the seasonal average. According to CBS News Chicago, high pressure is expected to maintain the dry and calm conditions, making for a quiet day.
However, the peace is to be short-lived, as a spring storm, currently crossing the country, promises to swiftly bring more volatile weather conditions. A severe storm threat to the south is anticipated, and as moisture from the Gulf converges with this system, it is forecasted to significantly increase rain probabilities in Chicago starting Tuesday evening. CBS News Chicago warns of potential localized flooding and thunder on the milder side of the system.
The forecast from the National Weather Service describes the upcoming shift, with Monday seeing a slight chance of showers and a high near 44 degrees. Conditions only to deteriorate further into Monday night, with a 30 percent chance of rain after midnight as the clouds gather strength.
As the storm's center prepares to pass over on Wednesday, temperatures are expected to take a nosedive. The National Weather Service indicates that on the back edge of the storm, cold air will wrap into the system, initiating a mix of strong cold winds and a transition from rain to snow. This temperature plummet signifies the storm's potency and the stark contrast to the preceding calm.
The rest of the week's forecast in Chicago continues this unsettled trend, with rain and even possible thunderstorms on Wednesday and a substantial 100% chance of precipitation that day. The tumultuous weather is to then peak into a chance of snow before midnight as temperatures dip into the high 20s.
After the storm has moved on, Chicago will see a return to sunnier skies by Thursday, with a high that climbs back up into the low 40s.
