...UPDATE...

.DISCUSSION...
Multiple outflow boundaries interacting with the hot and humid
conditions over the higher terrain locations of far Southeast
Oklahoma and Northwest Arkansas allowed for isolated to scattered
showers and thunderstorm to develop this afternoon. By mid
evening...most of the precip had dissipated with the loss of
daytime heating. A remaining thunderstorm was locations over
Madison/Carroll counties. Across the rest of Eastern Oklahoma and
Northwest Arkansas...mostly clear to mostly cloudy skies were
common from northwest to southeast with the heat advisory having
expired at 9 pm.

Overnight tonight...the remaining precip will continue to
dissipate over the next hour or so with skies forecast to clear
out over Southeast Oklahoma and Northwest Arkansas. For Northeast
Oklahoma...mostly clear skies should remain common with perhaps
some some scattered high clouds pushing through along the Oklahoma
Kansas border.

A persistence in expected low temperatures will again be the way
to go for the CWA tonight as the ridge of high pressure dominates
over the Southern Plains. Any remaining cloud cover over far
Southeast Oklahoma and Northwest Arkansas could affect lows...though
with expected dissipation will adjust temps to close to what lows
over the past few night have been. The rest of the evening update
will be to adjust hourly sky grids and add minor tweaks to
dewpoint and wind grids based on current trends and observations.
The rest of the forecast seems to be handling well with
mentionable pops dropping off after 03z.
