AWUS01 KWNH 242115 FFGMPD TXZ000-OKZ000-KSZ000-250300- Mesoscale Precipitation Discussion 1208 NWS Weather Prediction Center College Park MD 512 PM EDT Fri Oct 24 2025 Areas affected...Eastern Portions of the TX Panhandle...Northwest TX...Southwest and Central OK Concerning...Heavy rainfall...Flash flooding possible Valid 242112Z - 250300Z SUMMARY...Pockets of heavy showers and thunderstorms may expand a bit more in coverage going into the evening hours. A localized threat of flash flooding will exist. DISCUSSION...The late-day GOES-E IR satellite imagery shows cooling convective tops across parts of the TX Big Country up into far southwest OK. The convection is becoming increasingly aligned with strengthening deep layer ascent associated with stronger upper-level jet dynamics downstream of the approaching upstream trough over the southern Rockies. This is coinciding with MLCAPE values of near 1000 J/kg focused up in close proximity also with a frontal zone draped across the region. Some additional uptick in the coverage of convection is expected going into the evening hours as larger scale forcing increases further and interacts with the modest pool of moisture and instability nosing up across the region. This will generally be near and east of an area of surface low pressure over the TX Panhandle, but more closely aligned with areas of strongest low-level convergence and frontogenetical forcing near the front. By later this evening, some of the uptick in the coverage of convection is expected to involve central OK as the southerly low-level jet here strengthens and yields stronger moisture transport. Expect rainfall rates in the near-term to be capable of reaching well into the 1 to 2 inches/hour range, but with some cell-training concerns in place, there may be some localized swaths of additional rainfall totals reaching 2 to 4+ inches by late this evening. This is consistent with a blend of the 18Z HREF and 12Z REFS guidance. This will drive a threat for mainly localized and urban flash flooding concerns.
