Dallas, Texas – Summerlike warmth is set to build across Texas, with temperatures climbing into the upper 80s and nearing 90°F during the April 1–7 period as a powerful heat dome expands across the Southern Plains.
According to the National Weather Service Climate Prediction Center, a strong high-pressure system is settling over much of the central United States, creating a heat dome that traps hot air near the surface. As air sinks beneath this system, it compresses and warms, pushing temperatures 20 to 30 degrees above normal for early April.
In Dallas and across North Texas, afternoon highs are expected to reach the upper 80s with some locations nearing 90°F, including Fort Worth, Waco, and Denton. Farther south, cities like Austin and San Antonio may also approach similar levels of heat. Overnight lows will remain warm, limiting cooling relief and increasing early demand for air conditioning.
The heat dome suppresses cloud formation, allowing intense sunlight to heat the ground throughout the day. This limits widespread rainfall, though isolated showers or storms may develop along the edges of the system and move through quickly.
The early-season nature of this warmth raises concerns, especially in areas not yet acclimated to sustained heat. Residents are urged to stay hydrated, limit outdoor activity during peak afternoon hours, and check on vulnerable individuals.
This heat dome is expected to persist through April 1–7, with additional advisories possible if temperatures trend higher or approach record levels across Texas.
