Overview
- A strong upper‑level ridge over the Plains is producing a multi‑day heatwave this week with forecast highs in the low to mid‑100s and heat‑index values likely above 105°F.
- A heat advisory is in effect for North Texas and officials warn heat warnings may be issued midweek as humidity pushes 'feels like' temperatures into the 105–110°F range.
- Overnight lows are expected to remain in the upper 70s to 80s, leaving little nighttime relief and increasing the risk of heat‑related illness for vulnerable people.
- The National Hurricane Center has upgraded a Gulf disturbance to high probability for development as Tropical Depression Two, which forecasters expect to become Tropical Storm Bertha and make landfall near New Orleans.
- The same ridge steering the Gulf system away from the Dallas–Fort Worth area will keep most of North Texas dry this week, though forecasters say tropical moisture could reach parts of Central and Hill Country later and bring isolated rain by the weekend.
