KEY MESSAGES

Issued at 1133 PM CDT Sun Aug 16 2026

- Widespread triple-digit high temperatures will continue through midweek, maintaining an elevated risk for heat-related illnesses.

- Increasingly dry soils and parched vegetation resulting from flash drought will support the threat of quick fire starts and rapid fire spreads. - Although rain will be hard to come by, a few opportunities will exist on Monday across SE Oklahoma and SW Arkansas.

DISCUSSION

Issued at 1138 PM CDT Sun Aug 16 2026

Upper-level heat ridge to remain centered across the ArkLaTex on Monday allowing for high temperatures to again climb to around 100 degrees across most locations, with portions of east and northeast Texas up to 103 degrees. As has been the case over the past few days, a pocket of drier air across east and northeast Texas could mix down during the afternoon bringing dewpoint values down into the 60s, limiting heat index values to near 105 degrees across these areas. However, the remainder of the ArkLaTex may not be so lucky as dewpoint values in the 70s will drive heat index values to 105 to 110 degrees, especially across northeast Louisiana and south-central Arkansas. Based on these numbers, the ongoing Heat Advisory will remain unchanged at this time.

A weak frontal boundary acrsos Oklahoma into Arkansas will shift south overnight. With the front being oriented across the I-30 corridor on Monday, could see a few storms developing across these areas during the time of peak heating.

Upper-ridge to build west on Tuesday signaling the beginning of a pattern shift that will become a little more evident from Wednesday onward. By Thursday, most of north Louisiana and Arkansas will struggle to reach 100 degrees, which has not been the case through this weekend and most likely into the middle of the upcoming workweek. Additionally, an upper- level trough swinging southeast along the northern periphery of the ridge could produce enough instability and mixing to restrict afternoon high temperatures across Arkansas and Louisiana to the mid 90s by Saturday. /05/

FIRE WEATHER

Issued at 133 PM CDT Sun Aug 16 2026

A combination of dry fuels, low afternoon relative humidity in the 25-40 percent range, and S to SW winds sustained near 10 mph with some higher gusts in the afternoon hours will maintain an elevated wildfire threat across all of our fire districts. These conditions will persist through early this evening with conditions beginning to slowly improve after sunset with RH values recovering and wind speeds gradually diminishing.
