Summer’s sizzling heat sets in as hit-or-miss storms could fire

Remaining Ad Time Ad - 00:00

ROCKFORD (WREX) — Highs in the 90s have been on break for a little over two weeks, but that is soon to change. Heat and humidity give rise to only isolated shower or thunderstorm chances through the week.

A main course of heat and a side of humidity:

Hopefully Stateline residents are ready to dig into summery heat. The start of meteorological summer in June featured plenty of 90° and higher days, but since the 4th of July weekend, 90s have been noticeably missing from the forecast. The cooler summer weather gives way to gradually increasing heat.

It's a "copy-and-paste" forecast Tuesday.

High temperatures Tuesday inch closer to the 90° mark, as hazy sunshine sticking around. A weak cold front moves through Northern Illinois by Tuesday evening. Not only does this introduce an isolated storm chance, it also ushers in a midweek "cooldown."

Wednesday's high temperatures drop into the lower 80s under partly cloudy skies. Midweek is likely to be the coolest day of the week, with a quick return to upper 80s and lower 90s by the second half of the week.

Thursday leaps to near 90°. Following that, temperatures flirt with 90° each day through the weekend. Friday and Saturday may end up being the hottest days of the week, with high temperatures days approaching the lower 90s.

Temperatures climb above average through much of the week.

Of course, it's not just the heat. The humidity builds in slowly through the week as well. Tuesday through Thursday stay slightly humid, then Friday and beyond get into muggy territory. We'll hold onto the higher humidity through the weekend, before conditions dry out a little next week week. The slight dip in humidity follows a slight cool down, as we fall back to the middle 80s by early next week.

Rain chances remain spotty:

Most days this week remain dry and sunny. Occasionally, we see some slight chances for rain, starting with Tuesday night.

An isolated shower or storm is possible as a cold front slides through Tuesday evening.

The front mentioned in the previous section may spark a few scattered showers and thunderstorms Tuesday evening. Like most of this summer so far, the showers will not be widespread, and many locations end up staying dry. Keep an eye on the sky Tuesday evening and be ready for a quick shower, just in case.

Slight chances for rain are in the forecast for Thursday as well as this weekend. A few more weak fronts are in the neighborhood, and could spark more scattered showers and storms. Overall, the chances are pretty low, so most spots stay dry this week. Same goes for next week, as our dry weather pattern keeps going.
