Summary
Eastern Iowa faces dangerous heat through at least Wednesday evening, with heat index readings of 100 to 110 degrees across the entire TV9 viewing area.
Low- to mid-90s temperatures, upper-70s overnight lows and strong southwesterly winds are expected to keep the hot, humid air mass in place, while most storms along a western cold front fade before reaching the region.
Dry weather is forecast through Wednesday, though isolated showers or storms could brush northern areas later tonight and slight storm chances return from Wednesday night into the weekend.
Later this week, highs near 90 and lower dew points may ease short-term heat danger, but forecasters still warn long outdoor exposure could remain risky through the holiday weekend.
