.DISCUSSION...
Issued at 1029 AM CDT Fri Sep 26 2025
A fairly stagnant weather pattern to persist through the forecast
period ending next Thursday. Aloft, northerly flow to prevail
through tonight, becoming northwest on Saturday, as an upper-
ridge builds into Texas. The upper-ridge will hold areawide
through the weekend. An upper-low across the Atlantic will migrate
west across the Appalachians late in the weekend and linger
through the end of the forecast period, reinforcing northerly flow
areawide through much of next week. Thus, stable and dry
conditions expected with skies remaining mostly clear each day.
The only anomaly to the pattern will be the possibility of a
period of overcast skies translating east across the region on
Monday night into Tuesday with a weak 700 mb front.
At the surface, high pressure centered across Arkansas today to
gradually lift northeast through the weekend with a ridge axis
holding across the ArkLaTex through Tuesday. Two strong areas of
low pressure across the southeast and into the Atlantic Ocean will
provide enough northerly forcing on their westward flanks to drag
a cool Canadian airmass south into the ArkLaTex by end of the
period. Afternoon high temperatures will average in the 80s each
day through the period while overnight lows will range from the
50s and 60s through Sunday climbing into the 60s by early to
midweek. /05/

(18Z TAFS)
Issued at 1229 PM CDT Fri Sep 26 2025
VFR conditions will continue through the 26/18Z TAF period. Cu
cigs have developed early this afternoon across NW LA/extreme Ern
TX, with the cu field more scattered elsewhere across the region.
These cigs should scatter out by mid-afternoon, before diminishing
around/shortly after 00Z Saturday. Some cu may linger though this
evening across portions of Cntrl/NE LA before SKC returns. Still
can`t rule out patchy FG developing late over portions of Srn AR/N
LA, which may result in some vsby reductions at ELD, but should
lift by 13Z. Another scattered cu field should again develop over
the area by 16Z, before again diminishing around sunset. N winds
around 5kts this afternoon will become Lt/Vrb or calm after 00Z.
