Early-Season Heat Increases Risk of Heat Illness

Well above normal temperatures, very low afternoon humidity, and breezy southerly winds will result in critical fire weather conditions across parts of North Texas today. A Red Flag Warning is in effect through 8 pm for areas west of a Bowie to Eastland line. Be especially cautious of anything that may ignite grass fires across this region today.

Hot, dry, and breezy conditions will result in an elevated to critical fire threat today. Wind gusts will be 25-35 mph with a few peak gusts up to 40 mph possible. Avoid any outdoor burning and avoid tossing lit cigarettes. Secure tow chains and never park or drive over tall grass!

The hottest day of this ongoing heatwave will be Sunday with widespread temperatures in the 90s. Areas around the Breckenridge to Graham area are expected to reach the triple digit mark. In addition to the heat, make sure you avoid any outdoor burning as breezy weather and low relative humidity increase the potential for grass fires. A cold front will move in by Monday, leading to cooler temperatures, but a warming trend commences on Tuesday with 90s by the middle of the week.

We’re forecasting high temperatures 20-30 degrees above normal this afternoon and tomorrow. Even though highs are “only in the 90s”, most of our bodies are not acclimated to these temperatures yet. Acclimatization is how the body gradually adapts and tolerates higher levels of heat stress. Simply put, our bodies need time to adapt to working and functioning in the heat. Acclimatization results in the following changes: - Body produces more sweat - Sweat contains less salt - Slower heart rate, slower body temperature increase, and more blood flow to the skin makes the body more efficient at getting rid of heat - Other factors that vary from person to person (e.g., general physical fitness, outdoor workers, etc.) will affect the acclimatization process. TLDR: Temperatures the next few days will be typical of June/July, so most of our bodies aren't ready for it. If you plan on spending extended time outdoors this weekend, be sure to #BeatTheHeat! #txwx
