Humid Tuesday:
Cloud cover will gradually give way to a partly sunny and humid afternoon across the Stateline. Dew point temperatures will be in the upper 60s, giving the air a more noticeably humid feel.
That added moisture could be enough to spark an isolated thunderstorm or two during the peak heating hours of the day. Any storm that does manage to pop-up will be brief and spotty, though could produce gusty winds at times. Overall, today’s severe potential remains low, with the Storm Prediction Center placing our area under a level 1 of 5 Marginal Risk. Chances remain isolated for tonight, with overnight lows falling to 70 degrees.
Wednesday’s Severe:
Looking ahead into Wednesday, the setup becomes more concerning for severe weather. A strengthening surface low lifting into northern Minnesota will drag a strong cold front towards the region, providing a somewhat better focus for storm development by the afternoon and evening hours. This morning, the Storm Prediction Center kept most of the Stateline region under a level 3 of 5 enhanced risk for severe weather.
Tornado potential looks to be greatest north and west of the area, especially across northeast Iowa, southeast Minnesota, and southwest Wisconsin – where storms have a higher chance of being discrete. Closer to home in northern Illinois and southern Wisconsin, the main threats will shift toward damaging winds along with the possibility for a few tornadoes as storms roll in Wednesday evening into Wednesday night. The evolution of today’s weather will be important to watch, as it could significantly influence Wednesday’s severe threat.
