.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 overperformance 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.
