478 FXUS64 KFWD 161918 AFDFWD Area Forecast Discussion National Weather Service Fort Worth TX 218 PM CDT Sat May 16 2026 ...New SHORT TERM, LONG TERM, AVIATION... .KEY MESSAGES... - Daily rain and storm chances (30-60%) return to the region on Monday and continue through the end of the week. Strong to severe thunderstorms will be possible on Monday and Tuesday. - Above normal temperatures are expected to continue through Monday, followed by cooler air mid to late week behind a cold front. && .SHORT TERM... (This evening through Sunday) Issued at 218 PM CDT Sat May 16 2026 Another warm and breezy afternoon is underway across North and Central Texas as lee-side troughing persists across the High Plains and maintains a fairly tight pressure gradient across Texas and the Southern Plains. The larger-scale pattern is preparing to turn more active as an upper trough digs toward the Rockies, but meaningful height falls and stronger ascent will remain well northwest of the forecast area through tonight. Locally, the 12Z FWD sounding sampled a stout capping inversion, which should keep the area dry despite continued moisture return and daytime heating. South winds will occasionally gust to around 25 to 30 mph this afternoon. There may be a dryline storm or two to watch well to our west late this afternoon or evening, but weak synoptic ascent, the warm elevated mixed layer, and weaker instability with eastward extent should cause any activity to weaken before reaching our western counties. Low clouds will expand northward late tonight into Sunday morning as low-level moisture continues to deepen. These clouds may be a little stubborn to scatter, and daytime temperatures Sunday have been nudged a bit below deterministic NBM guidance as a result. This also matters for the convective forecast. Lingering cloud cover would temper destabilization, keep inhibition stronger, and further limit storm coverage across North and Central Texas. If clouds scatter more aggressively, the dryline and any remnant boundaries would have a better chance to support isolated convection by late afternoon or early evening. A lead shortwave will eject northeast from Northwest Texas into the Southern Plains Sunday evening, but the strongest ascent should remain north of the forecast area. The best storm chances will be along and north of the Red River, with Central Texas more conditional. Coverage should remain isolated, but any storm that develops or moves into North Texas could become severe and capable of producing large hail and damaging winds. && .LONG TERM... (Sunday night through next Friday) Issued at 218 PM CDT Sat May 16 2026 Any isolated storms across North Texas Sunday evening should weaken and move east after sunset as the lead shortwave lifts northeast and instability wanes. A few elevated showers or storms may linger across parts of Central Texas Sunday night where warm advection increases, but coverage should remain limited. Low clouds are expected to return Sunday night into Monday morning, and (similar to Sunday) daytime temperatures for Monday have been nudged slightly below the NBM where lingering cloud cover may slow heating. The cloud cover will also matter for Monday`s convective forecast, since slower erosion would limit destabilization and keep inhibition stronger into the afternoon. A stronger shortwave will lift into the Central Plains on Monday, sending broader height falls and stronger ascent into the Plains while still keeping the best forcing north of North and Central Texas. Even so, dryline convergence and weakening inhibition should make storm development more plausible than Sunday, especially across western and northern portions of the region Monday afternoon and evening. Coverage remains uncertain with southern extent, but any sustained storm could become severe in an environment supportive of organized convection. Large hail and damaging winds would be the main hazards, with a lower but non- zero tornado threat where storms can interact with any remnant boundaries or locally backed surface winds. Storm mode is not especially clean-cut at this range. With the strongest upper-level support displaced north, storms that develop locally may have a tendency to become messy with time, including mergers or outflow- influenced clusters rather than remaining well-separated discrete storms. The main trough axis will progress eastward through the Plains Tuesday into Tuesday night, sending a cold front south/southeast into North and Central Texas. The front should provide the most coherent forcing of the period, with scattered to numerous showers and thunderstorms developing along and ahead of it. Exact frontal timing remains a meaningful uncertainty this far out, and recent guidance will likely continue to shift some from run to run. A slower frontal progression would increase storm chances Tuesday, allow more of the warm sector to remain in place longer, increase the potential for multiple rounds in some areas, and keep the severe threat active farther into Tuesday evening or Tuesday night. Shear should remain supportive of organized convection along and ahead of the front, though storm mode should become more linear or clustered as forcing consolidates along the boundary. Damaging winds may become the more prominent hazard, but hail will remain possible with stronger embedded updrafts. The increasing moisture depth will also support higher rainfall efficiency, so locally heavy rain will be possible where storms train along the front or interact with remnant outflow boundaries. By Wednesday, vertical motion becomes increasingly tied to post- frontal overrunning and additional perturbations embedded within the subtropical jet. Elevated showers and storms may continue, especially across Central Texas, as the positively tilted upper trough lingers with its southern flank extending back toward Northwest Texas. Severe potential should be lower than Tuesday, and any stronger storms would likely to produce hail if enough elevated instability remains. The forecast becomes more nebulous Thursday into Friday. The front may settle near the Gulf Coast Thursday, keeping the better rain chances south of the forecast area, but another subtropical shortwave could bring renewed ascent as the boundary begins to retreat north Friday. This is why the gridded forecast may show PoPs each period through much of the week, but it should not be interpreted as nonstop rain. Instead, the late-week pattern favors periodic rounds of showers and storms, with coverage depending on the position of the front, timing of passing disturbances, and how quickly richer moisture returns northward. Confidence in the day-to-day details is lower late week, but the broader unsettled pattern should continue into next weekend. && .AVIATION... (18Z TAFS) Issued at 218 PM CDT Sat May 16 2026 Breezy south winds will continue through the afternoon with sustained speeds around 15 to 20 KT and occasional gusts near 25 to 30 KT. VFR will prevail through this evening. A more substantial surge of low clouds will arrive early Sunday morning, bringing MVFR ceilings to KACT around 07Z and the Metroplex terminals around 08Z. These ceilings will likely linger through Sunday morning before gradually lifting toward low VFR by early afternoon. The combination of the lingering cloud deck and a stout cap should limit destabilization through the day Sunday. While isolated convection may develop near or west of the region late Sunday, the probability of direct impacts to any TAF site remains too low for a mention this cycle. South winds will remain elevated overnight and become gusty again Sunday afternoon as boundary layer mixing improves. && .SPOTTER INFORMATION STATEMENT...
