Temperature highs across Nebraska will be anywhere from 93 degrees Fahrenheit to 105 degrees Fahrenheit. The index, which includes humidity, could exceed 110 degrees in some areas.

The National Weather Service has suggested precautionary actions. 

NWS said to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors.

DON'T FORGET BABY - With these hot temperatures, don't forget that young children and pets should never be left unattended in vehicles under any circumstances. It is never safe to leave a child, disabled person, or pet in a locked vehicle no matter the time of year. Reports have shown that a car is, on average, over 40 degrees hotter than it is outside; and in just ten minutes the vehicle can heat up by 20 degrees. 

Additionally, it is suggested that people take extra precautions if they work or spend time outside. When possible reschedule strenuous activities to early morning or evening.

It is necessary to know the signs and symptoms of heat exhaustion and heat stroke and wear lightweight, loose-fitting clothing when possible. 

NWS said that to reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent 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 so call 911.
