.KEY MESSAGES...

- Pleasant weather through the middle of next week with Fall-
  like temperatures and mainly dry conditions.&&

.SHORT TERM /THROUGH SUNDAY NIGHT/...
Issued at 149 PM CDT Sat Aug 23 2025

A pleasant summer weather is transitioning to lovely early fall
weather as we type. The primary cold front moved through early this
morning, and in its wake, northwest winds have mixed deeply in
sunshine today, resulting in mild temperatures, and quickly dropping
humidity levels. As of 1 PM, the surface dewpoints are now in
the 50s over our northwest 2/3rds CWA, after starting the day
with some areas still in the upper 60s to lower 70s. With the
deep mixing, northwest winds are breezy, with 15 to 20 mph
winds, gusting to 25 to 30 mph at times. These winds will ease
off towards sunset tonight, and with the dry air, temperatures
will see the first cool overnight in some time. Lows tonight
appear on target for lower to mid 50s, which should have many
opening your windows and turning off the AC this evening!

Sunday, a cooler day is in store, but well within the bounds of very
nice weather for outdoor activities. Highs appear set to return to
the upper 60s to lower 70s, which is near the NBM mean, but below
the NBM direct output.  We`ve coordinated with surrounding offices
to nudge this direction through Monday for high temperatures.

.LONG TERM /MONDAY THROUGH SATURDAY/...
Issued at 149 PM CDT Sat Aug 23 2025

Looking ahead, Sunday night through Wednesday night continues to
have high confidence of below normal temperatures, with mainly dry
conditions. Daily cumulus is expected to build each day, similar to
this afternoon. A few diurnal showers could occur each day, but
coverage and intensity appears very low, below mentioning in the
forecast for now, but if they happen, the northern counties would be
most likely to see them, as the coldest air aloft is found there
through Tuesday.   Low temperatures in this pattern will dip well
into the 40s, with some risk for nearing record low as suggested in
the previous AFD. There is no risk for any hazard in this weather,
so it`s just worth noting how pleasant this air will be during the
day, and how sweatshirts and jackets will be a handy addition to
your outfit by sunset each night.

Late this week, the upper trof will begin to flatten and shift east,
with temperatures returning to near normal, or in the upper 70s to
lower 80s. Mainly dry conditions remain forecast.
