It will continue to be hot and very humid with heat indices climbing above 100 across the entire area, with values between 105 and 110 degrees generally east of U.S. 281 Sunday afternoon. A Heat Advisory is in effect for this area. Remember your safety rules! Do not leave pets or children in vehicles, stay hydrated, limit strenuous outdoor activities in the afternoon, and take frequent breaks in the shade or an air conditioned building.
The hot weather will continue on Sunday, though some folks may get a break from the heat in the form of an afternoon thunderstorm. The highest rain chances will occur generally along and east of the Interstate 35 corridor, but all will see at least a slight chance of rain. High temperatures will approach triple digits once again, with heat indices well above 100.
An upper level ridge will build back across the region midweek, bringing some of the hottest weather so far to this summer. High temperatures will be in the mid 90s to around 100 degrees Monday and Tuesday and then will rise into the upper 90s to 105 degrees by Saturday. Heat index values will also steadily climb this week, likely exceeding 105 degrees across parts of North and Central Texas, and even in excess of 110 degrees by the end of the week and into Saturday.
Yes, it's July and it's hot. So you're probably thinking why is the National Weather Service bothering us? 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. If you or someone you know, is in the heat and suddenly stop sweating, get a throbbing headache and/or nausea, these are signs of heat stroke and it 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.
