The National Weather Service has issued Heat Advisories and Excessive Heat Warnings for much of Central Illinois from Wednesday afternoon through early Saturday evening as the area is expected to see its longest stretch of 90-degree temperatures of 2017. 

An area of high pressure that has brought cooler than average conditions to Central Illinois this past weekend will continue to sag south of the area on Tuesday. This will allow hot and humid conditions that have been sitting out west to flow back in to Central Illinois. Temperatures will top out in the 90’s through Sunday with heat index values above 100-degrees from Wednesday through Saturday.

The high heat and humidity can make it very difficult for the body to cool itself off. When temperatures are high and relative humidity is above 60%, your body will struggle to cool as the sweat on your body evaporates slower and slower. This can lead to heat related illnesses such as Heat Exhaustion and Heat Stroke. Below are the signs of each… 

Heat Exhaustion

   – Feeling Faint or Dizzy

   – Excessive Sweating

   – Cool, Pale, Clammy Skin

   – Nausea or Vomiting

   – Rapid, Weak Pulse

   – Muscle Cramps

What to do when you, or someone you know, is suffering from Heat Exhaustion: Get to a cooler and air conditioned place and drink plenty of water. Take a cool shower or use cold compresses. 

Heat Stroke

   – Throbbing Headache

   – No Sweating

   – Body Temperature Above 103°/ Red, Hot, Dry Skin

   – Nausea or Vomiting 

   –  Rapid, Strong Pulse

   – May Lose Consciousness 

What to do when you, or someone you know, is suffering from Heat Stroke: Call 9-1-1! Take immediate action to cool the individual down until help arrives. 

On average, heat is the number one cause of weather related fatalities in the United States. When Excessive Heat Watches, Warning or Advisories are issued it is important to take them seriously. Here are some tips to keep you safe during the upcoming heatwave.

   – When working or playing outdoors, stay hydrated and take frequent breaks in the shade. You should try to limit any strenuous outdoor activity.

   – Don’t be afraid to check up on your neighbors, especially those who are elderly, sick and those without air conditioning. 

   – Never leave kids or pets unattended in vehicles. When making that “quick” errand, it may be best to leave the pets at home. When the outside temperature is 90° the inside of your car can climb to a temperature of 109° in just 10 minutes and climb over 120° in just 30 minutes, not including the heat index!

Storm chances will increase on Friday, Saturday, and Sunday but they will offer very little relief from the heat until a cold front moves through Central Illinois Sunday bringing cooler and less humid air to Central Illinois.
