A Heat Advisory is in effect along and east of a Bowie to Killeen line through 7 PM. Highs today will be in the 90s to around 100 degrees. When you factor in the humidity, it will feel like it is 100 degrees or higher. Most locations in the Heat Advisory will have maximum heat index values of 105 to 109 degrees. The only relief from the heat will come in the way of scattered mainly afternoon and early evening thunderstorms. Gusty winds, heavy rain and cloud to ground lightning will accompany some of the storms. From mid afternoon through the early evening hours, a few storms may briefly become severe producing damaging downburst winds. .
There will be a risk for isolated thunderstorms this morning across parts of Central TX and across the Big Country. The better risk for more widespread showers and thunderstorms will be this afternoon across the remainder of North and Central TX. Not ALL locations will see rain. Some storms could be strong to severe in the afternoon with damaging downburst winds being the primary hazard. Heavy rain combined with the slow movement of storms may result in some minor flooding.
There will be a threat for lingering storm chances Sunday night into Monday morning across much of North and Central TX. The better risk for more widespread showers and thunderstorms will be Monday afternoon. The best risk for storms will be along the Red River. The main threats with storms on Monday will be strong to severe downburst winds, frequent cloud to ground lightning and heavy rain.
There will be a chance of showers and thunderstorms Monday across most of North Texas. An upper level ridge will build east Monday through Thursday bringing hot, rain-free weather. The ridge will weaken its grip on the region late week, allowing for low chances of showers and thunderstorms across the northwest Friday afternoon and area wide Saturday. Highs will be in the 90s Monday, then mid 90s to 103 degrees Tuesday through Saturday. Heat index values will climb during the week, likely reaching 105 degrees across parts of North and Central Texas starting Tuesday and maybe approaching 110 degrees mid to late 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.
