Rockwall County residents face heat index values as high as 106 degrees through Tuesday, Sept. 15, as a Heat Advisory remains in effect across much of North Texas.

The National Weather Service Fort Worth office issued the advisory covering portions of North and Central Texas along and east of the I-35 corridor. The NWS warns of heat index values up to 106 degrees, with high humidity increasing the risk of heat-related illness for anyone working or spending time outdoors.

WFAA meteorologist Cassie Heiter reported Monday, Sept. 14, that the feels-like temperature could climb to 108 degrees on Tuesday, Sept. 15. Most locations across North Texas are running 10 to 15 degrees above normal, and forecasters expect the region to tie or break more record highs over the next several days.

The heat is part of a punishing stretch. Sunday, Sept. 13, hit 103 degrees in the Dallas-Fort Worth area, marking the 12th triple-digit day of September and setting a record for the most 100-degree days ever recorded in the month, KERA News reported. North Texas has logged 49 days at or above 100 degrees in 2026.

The region has also gone 60 days without measurable precipitation, according to NWS meteorologist Sarah Barnes. August 2026 was the driest August on record for the Dallas-Fort Worth area.

"The biggest impact has been the onset of severe to extreme drought conditions, especially in North Texas," Barnes told KERA News on Sept. 14.

Moderate and severe drought has expanded across the region, and burn bans are in effect for every county in North Texas, according to WFAA. In Rockwall County, the Commissioners Court enacted a 90-day burn ban on Aug. 25 covering unincorporated areas. The order runs through Nov. 23. Violating the ban is a criminal offense under Section 352.081 of the Texas Local Government Code.

The burn ban does not apply to incorporated cities such as Rockwall and Heath, which may have separate rules.

Barnes said a more active weather pattern may arrive in the coming days, but uncertainty remains about whether the hot and dry stretch will break. WFAA's 14-day forecast suggests triple-digit highs should end in the back half of September, though temperatures will stay well above typical fall levels.

The NWS advises residents to stay hydrated, wear lightweight and loose-fitting clothing, and limit strenuous outdoor activity to early morning or evening hours. Check on neighbors and relatives, and never leave children or pets in an enclosed vehicle. Heat stroke is a medical emergency. Call 911 immediately if someone shows signs of it.
