  Concho Valley areas this afternoon and again on Saturday
  afternoon.

- Hot and mainly dry weather will persist through next weekend.

.SHORT TERM...
(This evening through Saturday)
Issued at 1253 PM CDT Fri Aug 21 2026

Starting to feel like a broken with the same song stuck playing,
but hot continues as the upper ridge dominates. At least we didn`t
say dry this time although most areas will remain dry as will.
Based on more of the CAMs showing isolated convection with a weak
shortwave tomorrow afternoon and evening, did add 10% POPs over
more of the area and mention isolated thunderstorms possible.
Otherwise, forecast highs expected to be very near todays highs
and extended the Heat Advisory into Saturday afternoon as well.

Will need to keep an eye on morning lows. So far this week,
morning lows have been able to drop into the 70s (and even 60s at
times) with the dry air mass in place. But morning lows are
creeping up towards the upper 70s across the Big Country. This
makes the heat a little more unbearable and increases the risk and
heat stress.

.LONG TERM...
(Saturday night through next Friday)
Issued at 1253 PM CDT Fri Aug 21 2026

Again, not much to change with the ridge persisting through the
next week and likely even longer. Center of the upper high does
shift a little farther west and this may allow temperatures to at
least cool enough to cut a few counties out of the Heat Advisory.
Temperatures are still likely to exceed 100 degrees though.

Of note again, Abilene has already hit 100 degrees this afternoon,
marking the 20th consecutive day. Forecast shows 100+ each day
this week for Abilene which means that their run at their record
of 30 consecutive days will be occurring next weekend.
