.SHORT TERM...
(Tonight through Tuesday Night)
Issued at 1036 PM CDT Sun Aug 10 2025

It was a quiet day across the area thanks to broad high pressure
situated overhead. It`ll be another quiet night as well with mostly
clear skies and light winds. There`s a low chance for patchy fog,
primarily across the Plateau in the usual trouble spots. A pattern
change takes place this week though with a troughing pattern taking
shape over the Plains. Moisture advection increases Monday, starting
a trend which will see steadily increasing rain chances through mid-
week. Rain chances Monday will still be low, generally in the 20-30%
range and focused across the south and east. Otherwise, the very
warm temperatures stick around with highs in the low to mid-90s and
the increased humidity sending heat indices into the upper-90s.

Moisture values continue to increase on Tuesday, sending PWATs up to
1.75-1.90 inches, which is near the 90th percentile for mid-
August. Rain chances will still be on the rise with 35-55% chances
maintained in the forecast with best chances in the afternoon and
early evening. Temperatures stay in the low-90s, but heat indices
will still be high with locations making it up to the upper-90s
to low-100s.

.LONG TERM...
(Wednesday through next Monday)
Issued at 1036 PM CDT Sun Aug 10 2025

Rain chances will peak on Wednesday to 50-70% as a weak trough
tracks through the area and PWATs get to near 2 inches. Ridging
tries to build back late week and into next weekend, and PWATs trend
back down to seasonable normals (around 1.5 inches). This will be
enough to keep low to medium rain chances (30-50%) in the forecast
through the weekend. Best chances will be each afternoon and evening
with these diurnally-driven storms. Severe weather threat is very
low, but typical thunderstorm hazards of heavy rain, frequent
lightning, and gusty winds are all on the table. Otherwise, high
temperatures will hover in the low to mid-90s with daily heat
indices reaching into the upper-90s and low-100s.
