The coolest weather of the week arrives Wednesday

Remaining Ad Time Ad - 00:00

ROCKFORD (WREX) — A cold front brings temperatures down for the middle of the week, but don't look for the weather to stay that way. Hot and humid weather quickly moves in by the weekend.

One-day break:

After hitting 90 degrees Tuesday afternoon, we may end up 10 degrees cooler by Wednesday afternoon. The cold front leaves us in the upper 70s for most spots. Rockford may just get to 80 degrees.

We get a quick dip in temperature Wednesday, providing the coolest weather for the week.

This isn't too far away from average, as our typical weather is in the middle 80s for this time of year. Look for partly cloudy weather with a light northeast breeze to round out conditions. The humidity doesn't drop much if at all. That said, we don't see any increases until later this week, so the muggy air stays out of our hair for the time being.

Hot weather comes back quickly, so soak in the cooler weather while we have it!

Hot summer weather:

Starting Thursday, our mini heat wave sets up in the Stateline. Temperatures by that day rise to the upper 80s, though most spots fall short of 90 degrees.

The 90s are in full effect starting Friday. Saturday copies Friday's weather, then Sunday warms up a couple more degrees. That puts us in the middle 90s, providing some of the hottest weather since early this month. Monday may stay in the low 90s, then we cool off below that value early into next week.

Get ready for the heat, as the heat index may approach 100 degrees by Sunday.

Of course, it's not just the heat. The humidity is on the rise starting Thursday, and gets to muggy levels this weekend. With the humid air factored in, the heat index hits the middle 90s Friday and Saturday, and could be near 100 degrees by Sunday. Plan accordingly for the hot weather coming this weekend! Drink plenty of water leading up to and through this weekend.

Little to no rain:

Despite all of the changes in the temperature, the weather outside of that doesn't change much. There is a slight chance for rain Thursday as the heat moves back in. Friday and Saturday have slight chances for rain. However, like we've seen most of the summer, any rainfall will be very spotty.
