HASTINGS/OMAHA, NE – June 18, 2025 – Residents across central, east-central, and south-central Nebraska, as well as eastern Nebraska and western Iowa, are bracing for dangerously hot conditions this weekend as the National Weather Service has issued an Extreme Heat Watch. The watch will be in effect from Friday morning, June 20th, through Sunday evening, June 22nd, with heat index values potentially soaring up to 109 to 110 degrees Fahrenheit.
The heat index, or “feels like” temperature, accounts for both air temperature and humidity, indicating how hot it actually feels to the human body. High humidity significantly reduces the body’s ability to cool itself through sweating, making these elevated heat index values particularly concerning.
According to messages from the National Weather Service offices in Hastings and Omaha/Valley, NE, overnight temperatures during this period are only expected to dip briefly into the upper 70s and low 80s, offering little relief from the daytime heat. This sustained warmth increases the risk of heat-related illnesses.
Affected Areas Include (but are not limited to):
- Nebraska: Valley, Greeley, Nance, Sherman, Howard, Merrick, Polk, Buffalo, Hall, Hamilton, York, Adams, Clay, Fillmore, Webster, Nuckolls, Thayer, Knox, Cedar, Thurston, Antelope, Pierce, Wayne, Boone, Madison, Stanton, Cuming, Burt, Platte, Colfax, Dodge, Washington, Butler, Saunders, Douglas, Sarpy, Seward, Lancaster, Cass, Otoe, Saline, Jefferson, Gage, Johnson, Nemaha, Pawnee, and Richardson counties. Major cities impacted include Kearney, Grand Island, Hastings, York, Lincoln, Omaha, and Fremont.
- Iowa: Monona, Harrison, Shelby, Pottawattamie, Mills, Montgomery, Fremont, and Page counties. This includes cities such as Council Bluffs, Shenandoah, and Red Oak.
Impacts and Precautions:
Heat-related illnesses, which can range from heat cramps and exhaustion to life-threatening heat stroke, increase significantly during periods of extreme heat and high humidity. Symptoms of heat-related illness include heavy sweating, fatigue, dizziness, nausea, headaches, and a rapid pulse. In severe cases, confusion, slurred speech, and loss of consciousness can occur.
The National Weather Service strongly advises the public to take precautionary and preparedness actions:
- Drink plenty of fluids: Stay hydrated by consuming water or electrolyte-rich beverages, even if you don’t feel thirsty.
- Stay in an air-conditioned room: Seek out air-conditioned environments as much as possible, whether at home, a community cooling center, or public buildings.
- Stay out of the sun: Limit outdoor activities, especially during the hottest parts of the day (typically late morning to early evening).
- Check up on relatives and neighbors: Ensure vulnerable individuals, such as the elderly, young children, and those with pre-existing health conditions, have access to cool spaces and are staying hydrated.
- Never leave young children and pets in unattended vehicles: Car interiors can reach lethal temperatures in a matter of minutes, even on days that don’t feel exceptionally hot.
This extreme heat event marks a dramatic entrance for summer in the region, with forecasters warning of dangerous temperature impacts. Residents are urged to monitor forecasts closely and prioritize heat safety measures throughout the weekend.
