108° Incoming: Extreme Heat Warning Issued
Dallas Weather Alert: Extreme Heat Wave Hits North Texas This Week
What’s Happening Right Now?
DALLAS – North Texas is in the middle of a serious heat wave! Think of it like nature turned the oven up to "broil" and forgot to turn it off. We’re talking near-record temperatures, dangerous heat index values (that’s what it feels like with humidity), and only a tiny chance of rain to cool things down.
IMPORTANT ALERT
Extreme Heat Warnings are active across most of North Texas until 8 PM Sunday. This isn’t just "it’s hot outside" – this is dangerous heat that can make you sick quickly.
Sunday’s Forecast: The Peak of the Heat
Here’s what to expect today:
| Measurement | Value | What It Means |
|---|---|---|
| Actual Temperature | 107°F | Hot enough to fry an egg on the sidewalk (almost!) |
| Heat Index | 110°F+ | With humidity, it feels like 110°F – that’s "stay inside" territory |
| Rain Chance | ~10% | Mostly dry, few lucky spots might get a sprinkle |
| Warning Expires | 8 PM Sunday | Relief comes after sunset |
Morning Storms – What Happened?
Early this morning, some isolated showers and thunderstorms popped up across North Texas. Here’s the breakdown:
- Where they hit: Red River, Delta, and Hopkins Counties got the most action
- Severity: "Sub-severe" (fancy weather talk for "not super dangerous but still annoying")
- Main hazards: Frequent lightning and gusty winds
- Movement: Storm clusters moved south of I-20 toward Brazos Valley and through Johnson, Ellis, Hill, and McLennan counties
- Missed areas: Central Dallas and Tarrant counties stayed completely dry
SIMPLE EXPLANATION: "Heat Index"
Think of heat index like the "feels like" temperature. When humidity is high, sweat can’t evaporate off your skin as easily, so your body can’t cool itself. 107°F with high humidity feels like 110°F+ to your body!
Rainfall: Too Little, Too Late
The bad news: Any rain we got this morning was spotty at best – only about 10% coverage. That means 90% of the area got nothing!
The worse news: North Texas is in a worsening drought. Stage 1 drought conditions started last Thursday, and these measly sprinkles won’t help at all.
The Week Ahead: It Gets Worse Before Better
Monday-Tuesday: The Worst Days
| Day | High Temp | Heat Index | Rain Chance |
|---|---|---|---|
| Monday | 108°F | 110°F+ | Near 0% |
| Tuesday | 107°F | 110°F+ | Near 0% |
MONDAY IS THE HOTTEST DAY – 108°F actual temperature. This is serious heat!
Wednesday Onward: Slow Relief
| Day | High Temp | Trend | Rain Chance |
|---|---|---|---|
| Wednesday | 103°F | Cooling slightly | 10% |
| Thursday | 101°F | More comfortable | 20% |
| Friday-Sunday | Upper 90s/100°F | Near normal | 20% |
Why the change? The high-pressure system (the "heat dome") causing all this misery will finally weaken by midweek, allowing slightly cooler air and better rain chances.
How to Stay Safe: Your Heat Survival Guide
DO These Things:
- Stay indoors during peak heat (10 AM – 6 PM) if possible
- Drink water constantly – don’t wait until you’re thirsty
- Check on neighbors – especially elderly, those without AC, or with health issues
- Use cooling centers if your AC fails or you don’t have one
- Wear light, loose clothing and a wide-brimmed hat if outside
- Never leave kids/pets in cars – not even for "just a minute"
DON’T Do These Things:
- Exercise outdoors during peak heat
- Drink alcohol or excessive caffeine (they dehydrate you)
- Ignore symptoms of heat illness
- Assume "I’m used to Texas heat" – this is extreme even for us
Recognizing Heat Illness: Know the Signs
Heat Exhaustion (Serious – Act Fast)

Frequently Asked Questions
Q: What’s the difference between a Heat Advisory and an Extreme Heat Warning?
A: Think of it like storm categories. A Heat Advisory means "be careful, it’s dangerously hot." An Extreme Heat Warning means "this is very dangerous – take immediate precautions." We’re in the warning category right now.
Q: Why does the heat index matter more than the actual temperature?
A: Your body cools itself by sweating. When humidity is high, sweat can’t evaporate, so your body can’t cool down. The heat index tells you what temperature your body thinks it is – and that’s what determines your risk of heat illness.
Q: Will the rain chances this week help the drought?
A: Unfortunately, probably not much. We need widespread, soaking rains over several days to make a dent in the drought. The 20% chances late week mean only a few spots get rain, and it likely won’t be heavy enough.
Q: My AC is struggling/broken. What should I do?
A:
- Close blinds/curtains on sunny windows
- Use fans to circulate air (but don’t rely on fans alone above 95°F)
- Go to a cooling center, library, mall, or friend’s house during peak heat
- Take cool showers/baths
- Contact local 211 or 311 for emergency cooling resources
Q: Is this heat wave unusual for late August in Dallas?
A: Late August is usually hot, but 107-108°F is near-record territory. Normal highs this time of year are mid-90s. We’re running 10-15 degrees above normal, which is significant even for Texas!
