.SHORT TERM...
(Through tonight )
Issued at 1122 AM CDT Sat Aug 29 2026

Hot temperatures have returned to the area, with highs expected to
be in the upper 90s to low 100s across the forecast area. With dew
points in the low to mid 60s, heat indices will only be slightly
above actual temperatures. Accordingly, no heat products are in
effect for this afternoon. Skies will be mostly clear with just a
few high clouds and modest southerly wind.

Overnight tonight, southerly winds will not totally die off, which
will help keep lows higher. Most locations will remain in the 70s
with continued dry conditions.

.LONG TERM...
(Tomorrow through Saturday)
Issued at 1122 AM CDT Sat Aug 29 2026

The anomalously strong upper level high will continue to sit nearly
overhead Sunday and into early next week. Upper level heights and
temperatures will mostly be above the 90th percentile for this time
of year. This will keep conditions hot and stagnant, with afternoon
highs remaining 98-103 and overnight lows in the 70s. Mostly trimmed
temperatures to slightly below NBM values, which look too hot
overall. With continuous modest southerly flow, dew points will
gradually rise. These factors will support afternoon heat indices of
105-110 for good chunks of eastern OK and west- central AR. A Heat
Advisory is in effect Sunday for northeast OK, with additional
headlines likely in the coming days.

For the middle to end of next week the upper level high will
slightly shift, and become centered just east of the area, with
moisture levels slowly climbing as this occurs. Overall, the same
general pattern of heat and dry weather will persist. However, the
increase in moisture will be just enough for at least the chance of
some higher terrain diurnal showers or storms (10-15 percent
chance). Even longer range guidance (beyond day 7) has unusually
high confidence in the upper level ridge remaining near or overhead
through at least the next 10 days and likely beyond.

Fire weather concerns will continue each afternoon of the next week
due to hot, dry, and breezy conditions. Ensemble guidance shows
Sunday and Monday as the breeziest days overall.
