KEY MESSAGES

Updated at 1223 AM CDT Tue Jun 30 2026

- Hot, humid and dry weather persists this week. Heat advisory headlines are in effect Tuesday for portions of the area, and may be needed in the days following.

- Flooding continues on main-stem rivers in northeast Oklahoma.

- Low chances for afternoon storms in the terrain of SE OK and NW AR Thursday and Friday. Low storm chances continue with a weak front Sunday.

SHORT TERM

(Through Tuesday Night) Issued at 1154 PM CDT Mon Jun 29 2026

Eastern Oklahoma and northwest Arkansas remains between the dome of high pressure currently centered over the southeastern/eastern CONUS and surface high pressure centered over the high Plains. These features continue through Tuesday, which will continue the warmer and humid conditions across the CWA. Winds Tuesday are anticipated to be slightly lighter in response to the surface low out west weakening, and thus easing the pressure gradient force slightly over the region. Wind gusts of 15 to around 25 mph are still forecast though, which will help in the continued afternoon mixing of low level moisture/surface dewpoints. This should keep much of the CWA below heat advisory criteria with mid 90s to around 102 deg heat index values. The exception is the Arkansas River Valley of west central Arkansas. Have added southern Crawford and northern Sebastian cos to go along with Franklin co in a Heat Advisory for heat index values around 105 deg Tuesday afternoon. High temperatures in the low to mid 90s should be common for the CWA under mostly clear to partly cloudy skies. Lows in the 70s are forecast Tuesday night.

LONG TERM

(Wednesday through Monday) Issued at 1154 PM CDT Mon Jun 29 2026

The ridge of high pressure begins to reposition more to the east and northeast of the CWA Wednesday through the end of the week. This allows for more southeasterly low level flow to return moisture advection back into the region. The combination of moisture and afternoon heating could allow for a slight chance of storms to develop each afternoon for the second half of the week. The greater potential is across far eastern Oklahoma and western Arkansas Thursday and Friday afternoons. Any storm development could create localized strong wind gusts and heavy rainfall. Also with the slight increase in moisture content, afternoon temperatures look to be a couple degrees or so warmer compared to early week, which will aid in the potential for more locations to reach heat advisory criteria late week.

Over the weekend, the ridge of high pressure is progged to flatten while a shortwave moves into/through the Plains. Additional shower and thunderstorm chances develop, especially late weekend with a weak frontal boundary approaching the region. In the wake of the shortwave, surface high pressure becomes centered over the West/Desert Southwest for the start of next week with continued hot and humid conditions across the CWA.
