What a difference a day makes. After a spectacular 80º Saturday marked by brilliant sunshine and humidity levels below 20%, Chicagoans face the prospect of a very chilly Sunday as brisk NE winds sweep lake-chilled air into the city. Areas very close to Lake Michigan could experience a temperature drop of more than 30º with temperatures Sunday afternoon struggling to reach the lower 50s. The chill will moderate farther inland with readings reaching more comfortable levels in the lower and middle 70s in areas west of the Fox Valley. A few showers could accompany the cold air’s arrival Sunday morning, but any precipitation is expected to be quite light.
The chill will be short-lived with the mercury climbing well into the 80s with a few areas pushing 90º by Tuesday. In typical late spring fashion, another cold front will arrive by the end of the week with a round of potentially active showers and t-storms, followed by another temperature downturn.
