KEY MESSAGES

Updated at 1238 AM CDT Sat Aug 29 2026

- An extended period of hot and dry weather is expected to persist through at least the first week of September. The need for heat headlines will return on Sunday, likely persisting into next week.

- The ongoing drought situation will continue to worsen. Localized fire weather concerns will develop each day.

SHORT TERM

(Through Saturday) Issued at 1052 PM CDT Fri Aug 28 2026

A light southeast wind tonight will keep overnight lows from dipping as low as they were this morning in most areas, but the typical sheltered valley sites will get cooler. Daytime highs on Saturday will be either near or slightly warmer than they were today. The low dewpoints will keep heat indices under control and no heat headlines are planned. Winds will turn around to the south but will not be particularly strong.

LONG TERM

(Saturday Night through Friday) Issued at 1052 PM CDT Fri Aug 28 2026

The predominant upper flow pattern over the CONUS next week will feature broad upper ridging over the central and eastern CONUS, with troughing over the Northeast and the Pacific Northwest. Boundaries that could focus storms will stay well away from the area in this pattern. There is a hint of some isolated shower or storm activity in the terrain of western AR from Tuesday onward, but the signal is weak and thus confidence does not merit introducing PoPs at this point. The grand ensemble mean has positive 500mb height anomalies over the region clear through the first week of September, including the Labor Day Weekend. Temperature-wise, Sunday looks to be the hottest day of the forecast, with temps dialing back slightly and holding there (around 100F) for most of next week. Heat headlines will likely be needed for portions of the area Sunday and in the days following. Hot and windy conditions from Sunday into next week will bring fire weather concerns each day at least locally as the drought worsens.

The longer range outlook for week 2 from CPC, taking us through September 11th, continues to favor above average temps and below average precip.
