Area Forecast Discussion
National Weather Service Tulsa OK
1135 PM CDT Fri May 25 2018

A few isolated showers/thunderstorms continue across far
southeast Oklahoma but should not impact TAF sites. Dense fog has
already developed at KFYV and expect LIFR conditions to likely
continue for most of the night. Elsewhere across NW AR light fog
possible, otherwise VFR conditions expected with light winds
and mainly high clouds.


.PREV DISCUSSION... /Issued 944 PM CDT Fri May 25 2018/


Scattered showers and convection remained ongoing across Southern
Missouri and Northern Arkansas this evening in relation to a
mid/upper impulse drifting southeast just behind the precip. Some
of this activity was pushing through Carroll and Madison counties
in Northwest Arkansas. Across the rest of Eastern Oklahoma and
Northwest Arkansas...partly cloudy skies...light winds and temps
in the upper 60s/lower 70s were common.

Overnight tonight...the mid/upper level impulse is forecast to
continue to shift east southeast with the precip chances shifting
eastward across Central/East Arkansas. Some of the latest CAM
solutions also try to redevelop some showers/convection across
parts of far Southeast Oklahoma from any residual outflow
boundaries remaining within the higher terrain locations as the
impulse moves through the region. Latest meso-analysis indicated a
strengthening cap across Southeast Oklahoma from todays precip.
Also...the low level jet is forecast to remain across Southwestern
Oklahoma tonight. Thus...will carry chance pops for Northwest
Arkansas through next few hours and keep a slight chance pop for
far Southeast Oklahoma overnight...though confidence is on the
low side for Southeast Oklahoma.

Temperatures again tonight look to be close to previous nights
lows with dewpoints holding in the 60s. In response...will
continue with lows in the 60s for most locations and have added
only minor tweaks to hourly temps/dewpoint grids for the evening
