Less humid air moves in tonight and Monday
Northwesterly winds have kicked in this evening, and that has brought in some cooler and less humid air to eastern Iowa for tonight. Skies will be mainly clear tonight as we drop into the low 60s for overnight lows. Winds will be lessening to around 5-10 mph overnight. As we head into Monday, expect plenty of sunshine for the day as high pressure moves in. It will be slightly warmer than Sunday, but the mugginess will stay reasonable as dew points stay in the low and mid-60s.
The warmth and mugginess will start creeping back in as early as Monday night and Tuesday. Temperatures will soar back into the upper 80s for the rest of the week, with some areas hitting 90. The Fourth of July looks hot and sticky, and that may also lead to a few isolated storms in the area. Better chances for storms move in for Thursday as a cold front pushes in to bring us a cooler stretch next weekend.
