Warmer and more humid on Monday
Higher humidity is gradually returning to our atmosphere tonight, and that will keep our temperatures from dropping as much as last night. In fact, most areas should stay in the 60s. Skies will stay mostly clear through the overnight as high pressure still has a grip on our weather pattern.
Typical July heat and humidity comes roaring back to eastern Iowa on Monday. Under a mix of sun and clouds, our temperatures will climb to near 90 by the afternoon, as dew points close in on 70. This will result in heat indices around 95. With how comfortable it has been lately, it will be quite the adjustment and you will certainly notice the changes.
A weak cold front dives down from the north Monday night, bringing our winds out of the north Tuesday and Wednesday. This will bring our temperatures down a few degrees, as well as the dew points. Still, temperatures should be near to above average. Rain chances will arrive by Thursday night, but they are fairly low.
