A heat advisory has been issued for the entire DFW Metroplex, including Frisco. Afternoon heat index values are forecast to to reach or exceed 105F. Currently the forecast for the next 5 days calls for afternoon high temps to exceed the century mark and top out around 101F. Additionally, the very high temps and partly cloudy skies will be ideal for producing very poor air quality and a Air Pollution advisory has been issued. Pollution levels are forecast to reach level red, which is unhealthy for all groups including adults.
Essentially not only will it be extremely hot outside, the air is also very hazardous to breathe. So this means if you don’t collapse from heat stroke within 15 minutes, you may collapse from some severe respiratory aliment due to the horrible quality air, fun huh!?
