Good evening everyone, here is a look at the next five days across Northern Illinois. After our two frigid days, we should break into the lower 30’s Thursday and possibly the lower 40’s Friday. Skies will remain clear with passing clouds from time to time. No real apparent chance for precipitation across the region from the I-74 corridor up to the Wisconsin line. It isn’t until late Saturday that we will begin to introduce the next chance for a rain/snow mix across northwest Illinois. On Sunday the more organized system till begin to move in bringing showers and maybe even a thunderstorm or two toward central Illinois [Tri-State Area].
Temperatures will be the real story as we head into the middle of January. Highs from Friday through Sunday will range from near 40 degrees across the northern sections of the area to the upper 40’s toward central Illinois. Humidity will begin to increase once again through the weekend so I would not rule out some foggy conditions developing, especially late Saturday into Sunday. Temperatures will start off warm Monday, but plummet throughout the morning into the afternoon as a cold front charges through bringing a final shot at precipitation.
As far as specific precipitation times, those are still in limbo. The general thought is that a rain/snow mix will develop as a warm front lifts north late Saturday. This activity will impact mainly northwest and far northern lllinois. Once this initial precip moves out, scattered showers will prevail through much of the day Sunday before the cold front approaches the Mississippi River on Sunday evening. Showers and some thunderstorms will develop further south and west across the Plains and rapidly spread northeast toward the Middle Mississippi Valley into the Great Lakes. There is a low chance of severe thunderstorms well off the southwest of Northern Illinois. At most maybe a few rumbles of thunder across the southwestern portions of Northern Illinois from the Quad Cities down the I-74 corridor. The biggest threat will be from heavy rain fall and some gusty winds. This weather will continue overnight before the cold front passes Monday morning from west to east. Temperatures will fall from the 40’s through the 30’s and eventually settle in the 20’s late Monday.
At the current time the severe weather threat is low as well as the wintry weather side of things. We’ll have more updates to come!
