.DISCUSSION... Issued at 1243 PM CDT Tue Oct 14 2025
Including today, another four afternoons remain of the warm and dry trend which has defined the weather of recent weeks across the ArkLaTex. This afternoon finds the responsible high pressure parked overhead, nearly centered above the Four State Region. This high will lose its definition somewhat over the next day or so, but not its influence over our weather. A developing and amplifying ridge axis over the Great Plains and upper Midwest will keep the high positioned directly over our region through the day tomorrow. Only once Thursday arrives will the high open up, getting absorbed by the ridge, which will weaken as it slides eastward, hurried on its way by a developing trough over the Intermountain West which looks to introduce a true pattern shift from what has defined recent weeks.
Before that happens, however, quiet weather conditions will persist through the week, with highs climbing into the upper 80s and lower 90s each afternoon. Based on recent underperformance and the projected position of the upper level high, trended 1-2 degrees warmer than guidance today through Thursday. Guidance continues to hint at a very slight cooling trend to close out the week, likely a combination of the departure of the ridge and the NBM`s recent cool bias. Morning lows will remain generally in the upper 50s and lower 60s throughout.
The aforementioned upper level trough looks to reintroduce rainfall to the forecast on Saturday, for the first time in weeks for many sites, though specific details remain hazy, as long range forecast models are split on the setup. This morning`s 12Z GFS run depicts an emerging shortwave and closed low within the upper level flow, riding a more southerly course across central Texas. This feature is entirely absent in the corresponding ECMWF run, which features an intact longwave trough digging south across the Plains as it swings its attendant cold front into the ArkLaTex. The ECMWF solution is more favorable for organized severe weather, while the GFS run hints at less defined convection but more widespread rain showers. Probabilistically speaking, both solutions look equally likely at this point based on consultation of the WPC cluster analysis.
Despite this uncertainty, in one aspect the ensemble members show better agreement, with regard to timing. The current guidance favors a more progressive solution, pushing the system and its rainfall out of the ArkLaTex more quickly and leaving a mostly dry remainder to Sunday and beginning to next week. Finally, the area of risk highlighted in the Severe Weather Outlook for Saturday has been extended southwards, capturing a larger swath of the ArkLaTex, including cities along and just south of the I-20 corridor as well as all previously included zones to the north. Bear in mind, these potential impacts remain 5 days out, may change noticeably in that time, and will as always be carefully monitored through the course of the coming days.
