.SHORT TERM...
(Tonight through Sunday night)
Issued at 1256 PM CDT Sat Oct 11 2025
An upper level high continues to sit over West TX today. Surface
high pressure is centered over Central TX making winds across our
CWA light and variable. The airmass is drier again today with
dewpoints 5-10 degrees lower than 24 hours ago. The upper ridge
will continue to dominate during the short term keeping our
weather dry. The surface high will drift toward east. Winds will
remain light but become southeasterly tonight. With little change
in the pattern temperatures will be about the same as the last day
or two tonight through Sunday night.

.LONG TERM...
(Monday through next Saturday)
Issued at 1256 PM CDT Sat Oct 11 2025
The upper ridge will remain dominant through the middle of next
week. This will keep all forcing to our west and north, so our
weather will stay dry. Yesterday, both the GFS and ECMWF had an
interesting inverted trough form over the eastern Gulf and move
toward the west during the middle of the week. Today, both models
develop a similar feature, but it is farther south. If this pans
out any rain would be in Mexico. However, models develop a deep
upper trough over Rockies and SW US which absorbs the southern
wave and moves it across TX Friday. There is still not much lift
with this feature and almost no chance for rain. Maybe only a
glimmer of hope. Temperatures through the long term period will be
fairly persistent varying only a degree or two day to day. Highs
will be above normal and lows near normal.

(00Z TAFS)
Issued at 624 PM CDT Sat Oct 11 2025
VFR conditions are expected at area TAF sites through the current
forecast period. Easterly winds along I-35 gradually shift to
light and variable of light southerly overnight. South winds
continue tomorrow, with gusty conditions likely after 18Z. Out
west at DRT, gusty conditions linger for another hour or two, then
subside as winds trend east-southeast. Gusty winds likely to re-
develop at DRT tomorrow after 16Z.

.FIRE WEATHER...
Issued at 1256 PM CDT Sat Oct 11 2025
Dry conditions over the next week along with low afternoon
humidity, especially Sunday, will continue to promote the drying
of fuels across the region. Despite relatively weak winds,
elevated fire weather conditions are possible the next several
days, especially along and east of the I-35 corridor where fuels
are more drought stressed.
