In Delta and, more broadly, across the state of Iowa: This morning will start with mostly sunny skies and just a few clouds drifting through. Temperatures will be very hot, ranging from the low 70s to the mid-100s by midday. Expect the heat to intensify as the day progresses, with afternoon temperatures reaching up to 104 degrees Fahrenheit. Winds will be moderate from the southwest at around 10 mph, with gusts up to 18 mph, providing some relief but not enough to significantly cool the air. No precipitation is expected today, so it will remain dry throughout. It’s important to stay hydrated and take precautions against the heat, especially during the hottest part of the day. Keep an eye on the weather if you plan outdoor activities, as conditions can become quite intense.
