Area Forecast Discussion

1100 PM CDT Thu Aug 29 2019
.DISCUSSION...
The 06Z aviation discussion follows....
&&
.AVIATION...
A convective system over Kansas is expected to affect much of
northern, central, and eastern Oklahoma overnight into Friday
morning. Variable wind directions and speeds and occasional
thunderstorms are expected as the system moves southeast across
the area, then gradually dissipates during the morning on Friday.
New thunderstorm development is then expected to occur over
northwest Oklahoma Friday afternoon, spreading across most of the
rest of Oklahoma and possibly into north Texas by late evening and
overnight.

DISCUSSION...
The 00Z aviation discussion follows...
AVIATION...
Scattered TSRA in far southwest Oklahoma and adjacent parts of
Texas should dissipate by 03Z. There is a possibility that a storm
could affect KSPS, but the probability doesn't warrant a TEMPO
line. Additional storms are already forming over Kansas, and may
affect northern Oklahoma between 06 and 12Z, but are more likely
to move into the eastern half of Oklahoma after 08Z (affecting
KPNC as early as 09Z, and KOKC/KOUN a few hours later). After
those storms diminish in the afternoon, still more TSRA
development is expected around 21Z in northwest Oklahoma. Those
storms will likely affect much of the northern half of Oklahoma
during the late afternoon and evening.
CmS
PREV DISCUSSION... /issued 228 PM CDT Thu Aug 29 2019/
DISCUSSION...
Models show a thunderstorm complex developing in Kansas this evening
and moving southward into portions of northern OK overnight into
early Friday morning. The storm development is aided by a
disturbance moving through the flow. There is some uncertainty as to
how far west storms will develop and/or move with some models
keeping most of the activity east of the fa where as some of the
models would say the complex would affect at least portions of the
fa. Current thoughts are that some storms will affect the fa with
the most likely area being along and east of I-35. The thunderstorm
complex could continue to propagate southward across portions of the
fa into tomorrow afternoon. Some storms could be strong to severe in
the area with this complex with strong wind gusts the primary
concern. Locally heavy rain that could lead to flooding will also be
a concern. With this in mind, will issue a Flood Watch for portions
of the fa from 09Z-18Z Friday.
Another round of storms will be possible again Friday night into
Saturday with potentially another storm complex moving from
western/southern KS into parts of the fa. What happens Friday night
into Saturday morning could depend on what occurs with the complex
tonight into tomorrow and how much recovery is able to occur. Some
strong to severe storms could be possible again Friday night with
strong wind gusts the primary concern. Locally heavy rain that could
lead to flooding will also continue to be a concern. With additional
heavy rain possible, the Flood Watch may need to be extended in time
and/or area but only go through 18Z Friday for now due to
uncertainties of effects from the overnight and during the day
Friday's activity.
Models show the upper ridge will influence the region Sunday through
next week leading to dry and warmer conditions. Temperatures for the
middle into later portions of next week are expected to be at or
above average for early September.
