DALLAS — North Texas started Sunday with temperatures near record-high minimums as high pressure and tropical moisture kept conditions hot and humid across the region.
The temperature at Dallas-Fort Worth International Airport reached 82 degrees early Sunday, putting it within reach of the record-high minimum of 78 degrees set in 2013. Normal morning lows for this time of year sit around 70 degrees.
Other Texas cities also recorded unusually warm morning temperatures. Lubbock reached 81 degrees, San Antonio 80, Corpus Christi 82 and Brownsville 85.
High dew points, ranging from the 60s in western Texas to 80 degrees in Corpus Christi, pushed heat index values higher across the state.
Heat advisories remain in effect
Heat advisories remain in effect until 8 p.m. Sunday across North Texas and much of the eastern half of the state.
Forecasters expect temperatures to reach 101 degrees Sunday afternoon in North Texas. Humidity could push heat index values between 105 and 108 degrees.
High pressure will remain over the region through the next several days, keeping temperatures elevated. South-southwest winds of 10 to 20 mph could develop early in the week as a tighter pressure gradient forms, adding to the heat.
Morning temperatures could remain near 80 degrees through midweek, while afternoon temperatures could again reach 100 degrees or higher.
Fall heat could continue
The official start of autumn arrives Sept. 22, but recent weather patterns suggest North Texas could remain hot.
Temperatures on the first day of fall over the past five years ranged from 83 degrees in 2021 to 101 degrees in 2023. Last year, temperatures reached 95 degrees.
Meanwhile, the National Hurricane Center is monitoring one disturbance in the Atlantic. The system has a 20% chance of developing during the next seven days and currently poses no threat to Texas.
For now, North Texas residents should prepare for continued triple-digit temperatures and heat index values above 105 degrees through the week.
