Lyon, Osceola, Dickinson and O'Brien counties in Iowa are included in the advisory along with Pipestone, Murray, Cottonwood, Rock, Nobles and Jackson counties in Minnesota.

Hot and very humid air will settle across the region, bringing very uncomfortable conditions. While a south wind averaging 15 to 20 miles per hour will take a bit of an edge off the heat, people are advised to plan for a very humid and hot day.

Heat indices will quickly climb into the 90s by late morning, then top out from 100 to 110 during the afternoon. The highest heat indices will be from northwest Iowa through the Missouri River Valley into central South Dakota, where readings near 110 will be most likely.

The heat index is expected to remain above 90 degrees through about 10 p.m. Thursday.

People spending time outside should take extra precautions, the NWS stated, and should reschedule strenuous activities to early morning or evening. Be aware of the signs and symptoms of heat exhaustion and heat stroke. Wear light-weight and loose-fitting clothing when possible and drink plenty of water.

To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air-conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency. Call 911.

A heat advisory means that a period of hot temperatures is expected. The combination of hot temperatures and high humidity will create a situation in which heat illnesses are possible. Drink fluids, stay in an air-conditioned room, stay out of the sun and check up on relatives and neighbors, particularly those who are vulnerable.
