KEY MESSAGES

- A line of thunderstorms will move across the region late this evening into early Sunday morning. - Temperatures will remain above normal through next week.

DISCUSSION

Issued at 201 AM CST Sun Feb 15 2026

Latest water vapor imagery/RAP analysis showed the circulation around a closed low spinning over the ArkLaTex. Latest surface analysis had a surface low just east of the closed low. These features will become nearly stacked as they track east across our CWA today. Local radars showed a broken line of storms moving east across our southeast zones along and a head of the cold front associated with the surface low. Although the severe storm potential will end within the next hour or two, rain chances will be maintained today as the low pressure system moves across our CWA and into Alabama today. This system has come in a little faster than expected and will exit a little faster. As a result the chance for any measurable precipitation on the backside of the system is expected to end before this evening. In the wake of the low pressure system, temperatures will be much cooler but today's high and tonight's low temperatures will continue above normal.

Surface ridging and broad ridging aloft will move over our CWA Monday. The surface ridging will become oriented along the Gulf coast from the east Tuesday resulting in return flow that will work to gradually increase low level moisture back across our region. The broad ridging aloft will weaken through mid week. Dry weather along with above normal temperatures is expected Monday through Thursday. As we go into the end of the week several disturbances will be rounding the base of an upper level trough over the western CONUS. These disturbances will support several surface lows that will track well to our north but send a stalling frontal boundary across our northern zones Friday into Saturday. There remain timing differences but model consensus suggests a more potent disturbance will move across the region and help push the frontal boundary south of our CWA Sunday. /22/

AVIATION

(06Z TAFS) Issued at 1249 AM CST Sun Feb 15 2026

MVFR ceilings are moving in across most TAF sites preceding a convective squall line currently sweeping from west to east across the area overnight. Timing is near current through 15/08Z in Interstate 55 corridor at HKS, JAN and 15/09-11Z at HBG, PIB and MEI. Some low-level wind shear and frequent gusts in excess of 40 to 50mph cannot be ruled out at TAF site with more robust convection. Winds will gradually shift westerly then northerly in the wake of the low pressure in northwest TAF sites. There may be a brief improvement in ceilings but this will be short lived as MVFR stratus will build down to IFR to LIFR in north to east TAF sites (i.e. GWO, GTR, MEI) with accompanying light rain showers. Lastly, some brief gusts in excess of 40mph not tied to the storms may be possible between 15/12-18Z Sunday from the Delta and potentially further east. There will be gradual improvement to VFR ceilings after 16/01-02Z Monday, while slower improvements at HBG and PIB until 16/04-06Z near the end of the 06Z TAF cycle. /DC/
