KEY MESSAGES

Issued at 1248 AM CDT Wed Jul 22 2026

- An approaching frontal boundary will amplify hazardous heat mostly along and south of I-20 through Wednesday, prompting the issuance of multiple heat safety warnings.

- Slightly cooler air and some isolated rain chances (for eastern parishes) will offer a brief return to near-normal summertime heat (mid-to-upper 90s) through the end of the week into the weekend.

- Hazardous heat returns by early next week.

DISCUSSION

Issued at 1248 AM CDT Wed Jul 22 2026

Ridging will continue as the primary driver of weather conditions through the next week across the Four State Region with some brief variations due to the evolutions of its periphery. This evolution will occur first in the form of a dry frontal boundary that slowly drifts in from the north, boosting the efficiency of insolation and daytime heating via compressional heating. This has prompted issuance of both a Heat Advisory and Extreme Heat Warning across the southern two-thirds of the area. Northerly winds will continue until Friday as the weak frontal boundary returns back north as a warm front, quickly reintroducing the 70-degree isodrosotherm and gradually setting the stage for hazardous heat to return as Gulf moisture re-moistens the atmospheric column. Some isolated showers and thunderstorms could still form by Thursday/Friday afternoons, but they will be the main windows of any rain chances in the next seven days as the Day 1-7 WPC QPF values suggest most likely rainfall amounts of less than 0.25 inches areawide. Long-range guidance also suggests that ridging will build back eastward from the Southern Great Plains to reintroduce hazardous heat potential through most of the rest of the month.

With dew points expected to remain mostly in the low-to-mid 70s through this time and heat indices ranging at 105-115 degrees, hazardous heat will be impactful for all groups of people and not just heat-sensitive groups today. Precautions and awareness are encouraged to continue now against the elevated potential for heat illnesses. This includes (and is not limited to) altering outdoor plans, taking frequent breaks if you must be outside, checking the backseat of your vehicle, and knowing the signs and symptoms of heat exhaustion in addition to heat stroke.
