Cold air mass settles over Chicagoland for St. Patrick’s Day

Sunday is St. Patrick’s Day, but the air will have a winter-like chill.

It may look outside like it did on Saturday, when highs reached the upper 50s on a mild, pleasant day, but it’ll be much colder than that Sunday. A mass of cold, dry air has settled over Chicagoland, which will make 40 degrees a tough goal to reach on St. Patrick’s Day.

There’s also a chance for flurries or snow showers during the early part of the afternoon, as clouds will increase. Temperatures will again be in the high 30s on Monday before warming back up into the low 50s by Tuesday, the first day of spring.

Rain chances won’t likely increase until later in the week, around Thursday and Friday.
