Highs on Thursday will be in the upper 90s to lower 100s across North and Central Texas. When combined with humidity, heat index values will be 105 to 110 across most of the region. Strenuous outdoor activity should be avoided, but if one must work outdoors on Thursday, make sure to take frequent breaks and stay hydrated!
A Heat Advisory will be in effect through Thursday evening for counties along and east of a Bowie to Killeen line, including the I- 35 corridor. High temperatures in this area will rise into the upper 90s to 102 degrees. When you factor in the humidity, the heat index values will rise into the 105 to 109 range.
A pattern change will occur this weekend as the hot upper level high moves off to the northwest. This will bring northerly flow aloft to the region and push a cold front into the area by Saturday. The front will move through by Sunday with slightly cooler conditions with lower humidity expected behind it. There will be a low chance of rain each day from Saturday through the middle of next week.
It is July in Texas and it's hot. So you're probably thinking why is the National Weather Service telling us about the heat? Well, it's simple: heat kills. Know the signs of heat exhaustion versus heat stroke. Faint or dizzy with excessive sweating, that's heat exhaustion. Get to a cooler place and drink water. What if you or someone you know, is in the heat and suddenly stop sweating, get a throbbing headache and/or nausea? Well, these are signs of a Heat Stroke and this is an emergency situation. Your body is no longer able to cool off and if you don't get immediate care---it can be potentially fatal. If you're suffering from Heat Stroke, you should call 9-1-1 and then immediately take action to cool down. as you wait for help to arrive.
