A weak upper level low along or just off the Louisiana coast looks
to remain too far away to provide much influence to our region this
weekend. Best opportunity for any rain would be confined near the
lower to middle Texas coast. Today looks to stay rain free across
our region outside from perhaps a late day very brief light shower
while Sunday afternoon may be a little better for the sea breeze
bringing a few showers into our far southeastern counties. The
temperatures remain above average otherwise under partly to mostly
clear skies. The afternoon highs range from the mid to upper 80s
across portions of the Hill Country to the low to mid 90s for the
rest of the region. Nights are mild with the overnight lows from
the low to mid 60s to near 70 degrees.

Issued at 1248 AM CDT Sat Oct 4 2025
The upper level low along the northern Gulf coast erodes entering
the start of the workweek. It is supplanted quickly by mid-level
ridging building across the northern Gulf. The positioning of the
ridge initially through early next week could help to deepen and
increase the onshore flow slightly into Texas, which should help
draw some slightly higher moisture levels farther inland. Late
Tuesday through Wednesday could see the arrival of high clouds as
well with some ties to the Eastern Pacific. There looks like that
enough moisture is in play to maintain PoPs in the 10-20% range
Monday through Wednesday. Monday favors to the east of I-35 while
Tuesday and Wednesday could see the Hill Country and Rio Grande
involved. Rain chances diminish late week as the ridge slides
westward and becomes more centered over the state. With this
position, the ridge should also keep any deeper moisture from the
Bay of Campeche confined well to our south.
Temperatures remain steady and above average through next week as
well with highs ranging from the mid 80s in portions of the Hill
Country to the low to mid 90s elsewhere. Lows from the mid 60s
into the low 70s will be common.

.AVIATION...
(06Z TAFS)
Issued at 1248 AM CDT Sat Oct 4 2025
VFR flying conditions will prevail overnight through Saturday night.
Increased lower level moisture may allow for the development of MVFR
CIGs early-mid morning on Saturday as forecast moisture profiles
suggest. HREF probabilities are 10% or less at the sites with higher
probabilities of 30 to 60% over the Edwards Plateau and western Hill
Country. Have introduced SCT010 at KSAT/KSSF/KDRT and will monitor
trends for any CIGs. Light winds overnight mix to E to SE at 7 to 12
KTs on Saturday with a brief increase to 10 to 16 KTs with gusts to
25 KTs early in the evening. Speeds then decrease Saturday night.
