Excessive Heat Lasting Today, Peaking Friday Could Be Followed by Severe Storm Saturday

FREMONT – Extreme weather will continue through the end of this week, as excessive and dangerous heat gives way to the potential for severe storms.

Thursday and Friday, the greatest risk is from heat. An Excessive Heat Warning remains in effect through Saturday at 7PM for the entire eastern Nebraska/western Iowa region. Ambient heat will combine with high humidity to create dangerously high heat index values over 110°, especially between the hours of 1PM and 9PM. Outdoor activity is not recommended during that period, especially for children and the elderly or physically compromised.

There is a real risk for heat related illnesses during the Excessive Heat Warning, and anyone who will have extended exposure to the weather should take precautions against becoming ill. It’s also important to recognize the symptoms of heat-related illnesses and watch out for other people in your group.

Heat stroke symptoms include:

  • Throbbing headache.
  • Dizziness and light-headedness.
  • Lack of sweating despite the heat.
  • Red, hot, and dry skin.
  • Muscle weakness or cramps.
  • Nausea and vomiting.
  • Rapid heartbeat, which may be either strong or weak.
  • Rapid, shallow breathing.
  • Behavioral changes such as confusion, disorientation, or staggering
  • Seizures
  • Loss of consciousness

Heat Stroke (also known as sunstroke) usually comes after heat exhaustion. There are two types of heat exhaustion:

  • Water depletion: signs include excessive thirst, weakness, headache, and loss of consciousness.
  • Salt depletion: signs include nausea and vomiting, muscle cramps, and dizziness.

If you, or someone nearby, has symptoms of heat exhaustion, immediately get out of the heat and rest in an air-conditioned room. If you can’t get inside, try to find the nearest cool and shady place. Then:

  • Drink plenty of fluids, especially sports drinks to replace lost salt (avoid caffeine and alcohol).
  • Remove any tight or unnecessary clothing.
  • Take a cool shower, bath, or sponge bath.
  • Apply other cooling measures such as fans or ice towels.

Saturday Storms

 

Saturday afternoon into early Sunday, as a cooling front moves in to the area, eastern Nebraska and western Iowa will face a slightly elevated risk of storms capable of producing severe weather and heavy rainfall. If you have outdoor activities scheduled in the region, officials stress the need to remain aware of the forecast, current weather conditions and any severe weather warnings – especially from 1PM Saturday through 7AM Sunday.

Fortunately, the weather is expected to calm into temperatures near the mid-80’s with no severe weather forecast for next week.
