Intense Heat Persists Across South Central Texas with Highs Near 100°F

Intense Heat Persists Across South Central Texas with Highs Near 100°F

A strong upper-level high-pressure system is dominating South Central Texas, leading to persistent hot and dry conditions. Temperatures are expected to reach near 100°F (37.8°C) throughout the week, with heat index values climbing as high as 108°F (42.2°C). The ridge of high pressure is forecast to shift northwest toward the Four Corners region by Tuesday, but its influence will continue to keep the area under extreme heat. No significant rainfall is expected, and the weather will remain mostly sunny with minimal cloud cover. These conditions are expected to last through the workweek and into the weekend, making heat safety a critical concern for residents in the region. (Source: KSAT, 2026-08-16 10:35:21 GMT)

Learn how to recognize the symptoms of heat-related illnesses and take steps to stay safe during extreme heat conditions.

South to Face Days of Dangerous Heat and Humidity

South to Face Days of Dangerous Heat and Humidity

A powerful heat dome will keep the southern U.S. dangerously hot through Monday, Aug. 17, with little relief overnight. RealFeel® temperatures could climb toward 115°F, while high humidity increases the risk of heat-related illness. Little Rock, Arkansas, could see highs above 100°F through midweek, with nighttime temperatures potentially staying near 85°F in urban areas. Spotty storms may offer brief relief across the Southeast. By midweek, the heat dome could weaken from Missouri to Virginia, but dangerous heat will persist along the Gulf Coast.

Dangerous Heat Returns Monday with Triple-Digit Heat Index

Dangerous Heat Returns Monday with Triple-Digit Heat Index

A shifting frontal boundary is expected to bring dangerously high temperatures to the region on Monday, August 17, 2026. According to WITN Weather, air temperatures will climb to the mid to upper 90s, with dew points in the low to mid 70s. This combination will result in a heat index ranging between 100°F and 110°F (37.8°C to 43.3°C). Inland areas will experience the triple-digit heat index from 11 a.m. to 8 p.m., while coastal areas, including the Crystal Coast, may see these conditions as early as 10 a.m. The WITN First Alert Weather team has issued a First Alert Weather Day for Monday due to the hazardous heat and humidity levels expected throughout the day.

Chronic Pain Overlooked in U.S. Heat Warnings

Chronic Pain Overlooked in U.S. Heat Warnings

A recent study highlights the connection between chronic pain and extreme weather conditions, particularly heat waves, which are often excluded from public health advisories. Researchers tracked over 35,000 adults aged 50 and older across two decades, correlating their chronic pain reports with temperature histories in their neighborhoods. Findings suggest that sustained exposure to extreme heat or cold can exacerbate high-impact chronic pain, especially among rural and low-income populations. Rural residents face unique challenges, including older homes, higher energy costs, and limited access to healthcare, which amplify the effects of extreme weather on pain management. The study calls for chronic pain to be included in heat-related health risk plans and tailored cooling assistance programs for rural areas. (Source: PBS News, 2026-08-16)

South Heat Wave to Bring Triple-Digit Highs and Record Temperatures

South Heat Wave to Bring Triple-Digit Highs and Record Temperatures

A dangerous heat wave is gripping the southern United States, with temperatures soaring into the triple digits across states from Texas to Florida and the Carolinas. The heat wave, intensified by high humidity, is pushing heat indices above 105°F (40.5°C) in many areas, with some locations experiencing heat indices exceeding 110°F (43.3°C). This prolonged event is expected to persist through much of the upcoming week, with little relief even during nighttime hours. Morning lows are forecast to remain in the mid-70s to low 80s (23-28°C), particularly in urban areas. The National Weather Service has issued heat advisories and extreme heat warnings across the region, urging residents to take precautions against heat-related illnesses.

High Humidity and Triple-Digit Heat Pose Risks in Metro Phoenix

High Humidity and Triple-Digit Heat Pose Risks in Metro Phoenix

Metro Phoenix is currently experiencing a combination of triple-digit temperatures and elevated humidity levels, creating challenging conditions for outdoor activities. According to Hayley Root, an assistant professor at Northern Arizona University, humidity levels of 60-70% can significantly impair the body's ability to cool itself. This is unusual for the typically dry Valley climate, making it particularly hazardous for outdoor workers and exercisers. Root advises that these conditions can lead to increased cases of heat-related illnesses, especially on days with unexpected spikes in humidity. Symptoms of heat illness include dizziness, fatigue, headache, confusion, and irritability. Source time: 2026-08-16 08:00:17 GMT.
