Expect the holiday weekend to start off rainy and cold but turn sunny and very warm by Memorial Day itself.
“Monday will be mostly clear, in the upper 80s. Expect it to be very muggy,” said Eric Laufenberg, a meteorologist based at the National Weather Service in Lincoln. The warm front pushing east from the Rockies will follow these rainy days, and that spells humidity and heat index number that mean it will feel like temperatures in the 90s, he said.
The cool, gray days, thunderstorms and lingering showers are expected to give way to more summery weather. The forecast for today calls for showers and thunderstorms and a high temperature near 76.
Sunday is expected to be partly sunny, breezy and warm with a high near 88. Monday’s weather is supposed to be sunny and similarly hot.
“Just remember it’s time to bring the sunscreen out” as the seasons change, said Laufenberg.
That’s especially important for people heading to the pools. Seasonal public swimming pools in Bloomington and Normal officially open this weekend.
In water, you have even more risk from the sun’s rays because of the water’s reflectivity, he said.
