High pressure keeps conditions cool

Remaining Ad Time Ad - 00:00

ROCKFORD (WREX) – Cooler and drier air will stay in place for a couple more days before heat builds in over the weekend.

An area of high pressure overhead will keep conditions quiet and cool through at least Thursday. Temperatures will drop into the middle 50’s again overnight, with winds going calm. Thursday provides another day of sunny weather, with low humidity and highs in the low 80’s.

Over the weekend, conditions will feel muggier as the humidity keeps climbing. Temperatures will stay steady and in the middle 80’s. More cloud cover builds in over the weekend, but rain may not fall just yet. A few spots in northern Illinois are very dry, mainly near the Mississippi River and into western Ogle County. If this trend without rain continues, we could see a shift to drought conditions in these areas.

Since we are not getting the rain, who is? A large heat dome is in the place over the west and southwest, bottling up the high summer heat over that part of the country. Temperatures hit 100 degrees in spots of Texas, Utah, Kansas, and Oklahoma. Around the edges of the heat dome, showers and storms will pop up repeatedly. Since the heat dome is anchored to our west, we’ll see cooler, drier, and quiet weather stick around over us. We’ll slowly see warmer weather work in throughout the week, however.

A few weak disturbances move through the jet stream between Sunday and early. These could spark a few scattered showers and storms, but it’s too early to say if the disturbances are able to be close enough and strong enough to get rain going locally. A slightly higher chance for rain and scattered storms looks to move through next Wednesday. Currently, Rockford is close to 2 1/2″ below average for rainfall for this summer.
