All 99 of Iowa’s counties are again under a heat advisory as high temperatures across the state today (Tuesday) may approach 99 degrees — and even hotter. Miles Schumacher, a meteorologist at the National Weather Service, says it’ll be a steamy one. “Today may be the hottest day of the week,” Schumacher says. “Looks like we could see several areas of the state get close to record highs, right around 100, maybe just over 100, most other places at least mid-90s, with heat indices of 105 to 110.”

Many schools statewide will let classes out early again today. There were no record highs reported on Monday however Mason City set a record minimum temperature with a low of 74, breaking the record of 73 degrees from August 26th of 1955. Schumacher says a slight cool-off will arrive soon. Relief may be coming to the northeast half of the state on Wednesday and Thursday as highs may only reach the upper 80s and low 90s, though it’ll stay hot in the southwest at least until Monday or so.

Long-range forecasts call for more seasonal weather by the middle of next week, with highs back in the low to mid-80s and overnight lows in the 50s and 60s.
