Heat Dome Returns With First Day Of Summer

Sunday, June 19th 2016, 12:21 pm

Summer officially begins on Monday, but if you’ve spent any time outside in the past 10 days, it feels like it has already started. Today will be another hot day with highs in the low 90s. 

There is some good news: drier air has moved in, and that will keep heat index values below 100 degrees. After today, the heat index will increase back above 100 for the coming afternoons. 
We do have a slight chance for an isolated shower this afternoon. Chances for scattered showers are better to the west along Interstate 35 and to the southwest near Oklahoma City. 

Yesterday, Tulsa picked up about .1” of rain. Higher amounts around Skiatook, but McAlester caught almost an inch and half. 

An area of high pressure overhead will shift eastward and settle on top of us for the next several days. This area of high pressure which is also known as a heat dome will keep rain chances away for the most part. Temperatures will warm up with south winds every day and mostly sunny skies. 

Unfortunately, dew points will rise and humidity will get higher - so afternoon will become miserable by mid-week. It is important to stay cool and use heat safety. 

 Tomorrow summer officially begins as the sun moves to its highest most point over the Tropic of Cancer. It will be the longest day of the year, but at least it won’t be hottest! 

At 5:34 p.m., be sure to say hello to summer. After that, have a glass of ice cold tea or lemonade because we have a hot start to summer! 

 EMSA's tips for staying healthy in the heat:

  • PRE-HYDRATION is key in preventing heat-related illness.  Drink plenty of water or electrolyte replacement drinks several hours prior to and during long exposure to the summer heat.
  • Wear light-colored, loose-fitting clothing and a wide brimmed hat if working outdoors and take plenty of shade breaks.
  • No alcohol or caffeine. 
  • If you do not have air conditioning, find a cooling station or public space (such as libraries or malls) during the day.
  • Also, don’t limit your air conditioning. If you are concerned about your electric bill, call PSO. They have programs that could possibly help you.
  • Use the buddy system if working outdoors and check on elderly neighbors.
