ROCKFORD (WREX) — Dew points continue to climb through Wednesday as a slow-moving front pushes through the Stateline. The combination of heat and humidity is likely to result in a few showers and thunder.
Morning showers and late-day thunder:
Let's get one thing clear: Wednesday is not going to be a washout. If you have plans for being outdoors, plenty of dry time is likely. The morning hours feature a rain chance mostly north of I-88. This chance, albeit small, could lead to heavy rain in a few pockets.
Early morning storms over central Ogle County dropped 1/2" of rain or more in a short time. The footprint of rainfall early Wednesday is incredibly small, and that trend is going to continue.
A slow-moving front pushes through the far northern tier of counties later Wednesday, pushing precipitation chances along and south of I-88. Even in this area of the Stateline, rain chances are going to be pretty isolated and primarily confined to the 3 to 9 PM period.
Wednesday does feature a touch more cloud cover and humidity. Stepping out the door early on, that difference can already be felt as dew points are in the middle to upper 60s. Dew points climb to near 70° before cooling off as the cold front slides through Rockford. The slow-moving frontal boundary could keep areas south of I-88 into the lower 70s most of the day.
Shower chances persist:
Thursday is going to be a mostly dry day, however a lingering shower or storm is possible as the frontal boundary runs out of "juice" nearby. This threat again remains confined to areas along and south of I-88 for the most part, with a mix of clouds and sunshine for the majority of the day.
Most model guidance keeps rain chances very scattered, so don't expect any widespread relief from browning grass. This trend is something that is likely to persist into the start of August, as the Climate Prediction Center suggests.
