  will bring welcomed relief to ongoing drought conditions by
  the end of next week.

.DISCUSSION...
Issued at 140 AM CDT Fri Sep 19 2025
A synoptic scale metamorphosis toward a more active flow pattern
occurs over the weekend, heading into next week. It sets us up
for a reintroduction of smallish rain chances that grows toward
its peak in the high chance-low likely range by the start of the
new week. While model differences exist, it is looking
increasingly like this pattern shift will lead to a more
fruitful precipitation duration, or at least chances thereof,
that carries thru the entirety of the week and thereby offers
some real relief to our exacerbating drought conditions. PW`s
rising nearly a third, toward the 75th percentile, will assist
with overall pcpn efficiency...as weekly storm totals push into
the 1-2" range on average; some localized higher amounts in
stronger storms may potentially bring more appreciable relief.
Coincident with the evolution toward the wetter pattern will
come more clouds, lower overall heights, and a much welcomed
cooldown in high temperatures toward climo norms. Highs still
reaching/exceeding 90F will persist this weekend, then fall back
toward the lower half 80s on the daily for next week.

.AVIATION /12Z TAFS THROUGH 12Z SATURDAY/...
Issued at 140 AM CDT Fri Sep 19 2025
Increasing mid-high level bases are anticipated to yield VFR
CIGS at times today as a wave of low pressure begins to gain in
influence with high pressure shifting east with time. Diurnal
bases again beginning around 6-7K FT AGL may include isolated
CB`s during peak heating so low probs mentioned are maintained
for the relative better chance terminals (west).
