.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.
