Summary/Highlights:

The first full week in April will be very warm for many across the central United States. After what was a gorgeous weekend of temperatures in the 70s here in Chicagoland, the trend will continue, though noticeably wetter and more humid. Monday will feature warm temperatures and mainly dry conditions, though a chance exists for an early thunderstorm or two. Tuesday should be more of the same, with a chance for a few showers during the early morning hours and again late in the evening, By Wednesday, the air will start to become more humid as even warmer temperatures push into the area. I would not be surprised if most of Chicagoland sees 80 degree temperatures for the first time in 2021 on Wednesday, though it depends on a few factors. A cold front will pass through the area during Wednesday afternoon and evening, which will provide a chance for thunderstorms. It is unlikely that any of these thunderstorms will become severe, as that threat should remain well to our southwest. Thursday and Friday will both feature cooler temperatures, cloudy skies, and chances for occasional showers throughout the day. By the time we approach Saturday, we may be able to see some sun, however there is another possibility for some rain. Late in the weekend, expect temperatures to start climbing again along with much drier conditions.
