Issued at 111 AM CDT Wed Aug 26 2026

As of 1 AM CDT, temperatures across the region are in the upper 50s
to low 60s with winds out of the west to northwest around 10 mph.
High pressure and quiet weather remain in place today through
Thursday.

Friday morning brings the return of storm chances with an incoming
low pressure system. These storm chances are expected to last
through the day and into early Saturday morning. MLCAPE Friday
afternoon from the EC model is around 1500-2000 J/kg, falling to
between 1200-1500 J/kg Friday evening. Lapse rates are around 7.5
C/km. SPC may put out an outlook for portions of the forecast area.
Some 20-30% precipitation chances return Saturday evening. Limited
precipitation chances exist through the rest of the weekend into the
middle of next work week with increasing chances Tuesday. These
storm chances are too far out to nail down severe potential.

Temperatures will hover right around to slightly above average
through the 7-day forecast. Smoke is pretty limited for the next few
days. Winds look to stay relatively light through the period.
