.SHORT TERM...
(Today through Saturday)
Issued at 1201 AM CDT Fri Aug 14 2026

Mid-level ridging remains in control early this morning and is
expected to lead to continued hot and dry weather through the next
week. In the short term, afternoon highs and associated heat indices
have been right around Heat Advisory thresholds, but not widespread
enough to warrant the issuance of one. Once again, Thursday will
feature highs in the upper 90s to around 105 along the southern Rio
Grande Plains. Heat indices will hover between 103-107 with a few
spots, particularly in the Coastal Plains briefly touching 108-109
this afternoon. A weak disturbance rounding the base of the ridge
will send some low level moisture inland this afternoon, primarily
along and east of the I-35 Corridor, where we will carry 20 PoPs
this afternoon and early evening. A brief heavy downpour or two
along with an isolated thunderstorm is possible but not much beyond
that. On Saturday, hot and dry weather resumes with highs in the
mid 90s to 103 along with heat indices in the 102-108 range.

.LONG TERM...
(Saturday night through Thursday)
Issued at 1201 AM CDT Fri Aug 14 2026

Sunday and beyond, the mid-level ridge slides further west and
closes off any sort of window of opportunity for showers or storms.
Highs each day Saturday through Tuesday will top out in the mid to
upper 90s to around 103. Long range guidance from the CFS does
indicate a bit of a quick switch to a more active pattern as El Nino
takes shape this Fall in the months of September and October, but we
will have to wait and see how things evolve over the next few weeks.

.AVIATION...
(06Z TAFS)
Issued at 1201 AM CDT Fri Aug 14 2026

VFR conditions are expected over the next few hours before MVFR
ceilings develop over I-35 terminals, possibly spreading as far west
as KDRT after sunrise. After 15Z, VFR conditions are expected to
return. Wind may gusty at times through the period up to 20-25
knots.
