WEATHER ALERT DAY: Dangerous heat and humidity return through Friday


The ABC 17 Stormtrack Weather Team has issued a Weather Alert Day lasting from Sunday through Friday evening, as heat index values may span 105-116 throughout the afternoon hours.


Upper level high pressure will allow this heat to build un-interrupted, and aid in our weekend warm up. This "heat dome" setup may keep us hot well into this week.

The combination of warmer than normal temperatures and humid to tropical dew points at times will create potential for heat index values in the 105-116 degre range.


Monday and Tuesday saw some of the most severe heat thanks to abnormally high dew points into the upper 70s and even lower 80s. On Wednesday and Thursday, dewpoints will decrease slightly, but the heat index will still remain at similarly dangerous levels thanks to rising temperatures lasting until Thursday night.


Heat-related illness will be the main concern. At a heat index of 105 degrees, all people are serious risk of heat-related illness with prolonged exposure.

Heat related illness can sneak up on you, know how to protect yourself, and understand the signs to watch out for.

All people should stay inside if possible, and take steps to keep themselves cool if outdoor activity is a must.

Heat stroke and Heat exhaustion have varying degrees of severity. If a person has a throbbing headache, is NOT sweating, has a high fever, dry and red skin, a rapid pulse, nausea or unconsciousness, they may have heat stroke and 911 needs to be called.
