.DISCUSSION...
Issued at 1157 PM CDT Wed Sep 17 2025
With afternoon and evening convection dissipated, a quiet, mild and
muggy night is in store, as temperatures drop into the upper 60s
north to lower 70s south. Guidance continues to favor the
development of patchy fog in the overnight hours, diminishing after
sunrise. Thursday is shaping up to be yet another warm late summer
day, with widespread highs in the low to mid 90s and some sites
taking aim at the upper 90s again. Ensemble guidance is struggling
to resolve the potential for diurnally-driven convection, thus
elected to bump late afternoon and early evening PoPs up areawide to
reflect recent trends.
Overnight tomorrow night into Friday looks to see the arrival of
more organized showers and storms, but specifics on timing and
intensity remain hazy at this time. Earlier solutions introduce
storms as soon as midnight, with others delaying arrival until
daybreak or into the morning. As an upper level trough pushes south
and east over the Ozarks into Friday, a complex of showers and
storms will swing into the ArkLaTex from the northwest, clearing the
region by Friday evening. Rainfall through the day is expected to
moderate high temperatures, ranging from the upper 80s north to
lower 90s south.
Looking ahead into the weekend, upper level ridging looks to build
eastward out of Texas, hindering noteworthy rainfall chances and
allowing high temperatures in the low to mid 90s to maintain their
hold on the region. Weak disturbances in the upper level flow look
to kick up scattered chances for showers and storms north and west
late in the weekend, becoming more widespread into early next week
as a developing upper level trough deepens and pushes southeastward
over the Plains. As the pattern remains unsettled, daily rainfall
chances will continue to close out the long term forecast period,
with highs dropping from the 90s to 80s, and lows in the 60s and 70s
throughout.
