KEY MESSAGES

Issued at 321 PM CDT Sun Sep 13 2026

- Upper-level ridging will allow late summer heat to remain across the region, with more heat advisories likely beyond today through at least the first half of the upcoming week. - Rain chances will be largely negligible throughout the week as well, with only very isolated afternoon convection due to the influence of the dominant upper ridge.

- The ridge is expected to migrate back westward by late next weekend, paving the way for cooler weather to make its way south into our region.

DISCUSSION

Issued at 321 PM CDT Sun Sep 13 2026

Upper ridging continues to build into the region. Most of the area has remained dry today, but some isolated to scattered convection has developed over locations on the eastern periphery of the building ridge axis. This trend will continue through the remainder of the afternoon before diminishing during the early evening hours. From there, another mild and quiet night can be expected, with lows ranging from the low to mid 70s. With the building ridge in place, the current Heat Advisory over the entire Four- State Region will be allowed to continue through Monday evening. Afternoon highs on Monday will continue to range from the mid 90s to around 100 degrees. Some additional isolated afternoon convection will be possible again along the eastern periphery of the ridge, which will generally be locations in South-Central Arkansas and North & Central Louisiana east of the I-49 corridor.

Upper ridging will become anchored across the Lower Mississippi Valley and over the region through most of the upcoming work week. Expect drier conditions, although a stray isolated shower and thunderstorm can't be ruled out during peak heating. Heat headlines will likely remain across the region and cause some elevated fire weather concerns. However, long-term models continue to suggest a pattern change, with the ridge sliding west of the area. At the same time, the models continue to suggest some activity in the northern Gulf, which will need to be watched closely. This pattern change looks to bring us some much needed rain and cooler weather. /20/

AVIATION

(00Z TAFS) Issued at 647 PM CDT Sun Sep 13 2026

For the 14/00Z TAF update, another round of VCTS/-TSRA continues to weaken across the eastern airspace with lingering stratiform rains/-RA and isolated MVFR cigs. After 14/03Z, most convection will dissipate and clear the area, leaving FEW/SCT250 until 14/20Z as the next round of VCTS convection is set to redevelop once again from east to west through the end of the period. /16/

SPOTTER INFORMATION STATEMENT

Issued at 321 PM CDT Sun Sep 13 2026

Spotter activation is not expected, but an isolated strong to severe thunderstorm cannot be ruled out across parts of South- Central Arkansas and Northeast Louisiana through the early evening hours. /20/
