Hottest weather of the year (so far) arrives late this week

Remaining Ad Time Ad - 00:00

ROCKFORD (WREX) – After a slow start, summer heat gets into high gear for the rest of the week. That means our first 90 degree days, high humidity, and pop-up showers and storms thanks to the steamy air.

The rest of the day and night should remain dry, with partly cloudy weather. Tonight’s lows only drop to the upper 60’s. With the muggy air sticking around and calm winds, tonight will feel pretty stuffy.

Thursday could provide our first 90 degree readings of the year. With the high dewpoints near 70 degrees, the heat index will be in the upper 90’s. Since we haven’t had a lot of warm days like this yet, remember to drink plenty of extra water and take it easy in the heat. Find a cool spot to relax in after the hotter weather. Most importantly: do not leave your kids or pets in your car! The vehicle gets way too hot way too quickly, so leave them at home or take them with you.

Since the air will be very warm and steamy, showers and storms are possible. There is a low risk for severe weather with this. There isn’t a guaranteed trigger to get storms going, but one could materialize in the afternoon. Storms may quickly become strong to severe thanks to the ideal conditions. Wind, hail, and heavy downpours would be the main threats.

We have a slightly better chance for scattered showers and storms Thursday night and Friday morning. A line of storms will move in from Wisconsin. These have a slow risk for strong to severe activity.  Strong winds, large hail, and heavy rainfall will be threats. Friday through Sunday will be very similar to Thursday: low 90’s for highs, heat indices near the upper 90’s, and a slight chance for pop-up showers and storms.

Cooler weather comes in next week, with better chances for rain between Tuesday and Wednesday.
