Northwest Iowa also sees a few showers and rumbles near Sioux Center, Spencer, and Algona, where sticky air makes it feel closer to 105 despite a light south breeze.
Overnight, the focus shifts north and east. Nocturnal storms organize across northwest into north-central Iowa, while most of central Iowa likely stays dry. A stray pre-dawn shower or rumble canāt be ruled out, mainly along and north of I-80. Itās a warm, muggy night, with lows only slipping into the low to mid 70s.
Monday brings one last dose of heat and humidity, with highs near 90 and that familiar sticky feel. By Monday night into Tuesday, drier air finally arrives, trimming back the dew points and letting the sunshine work for us instead of against us. Highs settle into the 80s, and the air turns noticeably more comfortable.
Through mid to late week, temperatures hold in the 80s as humidity gradually eases further. By Friday through the weekend, readings hover near seasonal norms, and the air feels pleasant. Outdoor plans get a friendlier forecast, with more comfortable afternoons and cooler mornings to match.
