Expect a continuation of the isolated to widely scattered showers
and thunderstorms over the next few days with highs generally in
the low to mid 90s. Like previous days, many of you will remain
dry. But the lucky few will be blessed with a downpour and some
thunder. In terms of general concepts, there hasn`t been much of
change in the model guidance regarding next week`s weather. But
once you dig into the details, you`ll find run-to-run variation
regarding mid/upper level features. How far south will a deep
layer troughing extend? Will there be a cut-off low of some sort?
And what are the exact timing of these features? Regardless of the
uncertain answers, one thing we can say is that the signals still
point to a more unsettled pattern early next week, thus the
increasing PoPs this weekend and especially by Monday and beyond.
The potential increase in shower/thunderstorm coverage and cloud
cover suggests less hot temperatures as well. But the chosen blend
in our temperatures grids still shows highs around 90 next week.
Not exactly fall- like...

(00Z TAF Issuance)
Issued at 659 PM CDT Wed Sep 17 2025
Currently monitoring thunderstorms over SW Louisiana early this
evening. These storms are expected to weaken as they move WSW;
however, a brief period of -SHRA or -TSRA will be possible near
HOU and GLS terminals this evening. Light and variable winds
tonight will again strengthen around 7 to 10 kts by mid-late
Thursday morning. Scattered showers and storms will be possible in
the afternoon, though confidence in occurrence and coverage is
medium. Therefore, will continue with PROB30 through the end of
this TAF cycle. Overall, VFR conditions are expected through the
period.
