Area Forecast Discussion

657 PM CDT Tue Aug 16 2022

...New AVIATION...

.SHORT TERM...
(The rest of this afternoon )
Issued at 130 PM CDT Tue Aug 16 2022

Surface low currently moving into portions of northeast Oklahoma, located
west of Tulsa, with frontal boundary extending southwest into west-
central Oklahoma. Heat advisory continues for much of eastern Oklahoma
and west-central Arkansas with heat indices topping out in the 105
to 110 degree range in some locations.

Focus quickly shifts to the severe weather potential late this afternoon
into the evening hours. Areas across far northeast Oklahoma and northwest
Arkansas have already become moderately unstable this afternoon in zone
of stronger differential heating. Enhanced CU field has developed across
aforementioned area and expect widely scattered strong to severe storms
to develop by late afternoon as strong surface heating continues. As
mentioned in previous forecast discussion, inverted-V soundings with
DCAPE values around 1500 J/kg suggest damaging downburst winds are
likely in the stronger storms. Also, with deep layer shear increasing
by this evening, could see one or two supercell structures with
large hail possible.

&&

.LONG TERM...
(Tonight through Tuesday)
Issued at 130 PM CDT Tue Aug 16 2022

Severe weather threat will begin to decrease by mid to late evening
as atmosphere starts to stabilize and as precipitation becomes
increasingly elevated as front sags south overnight.

Lingering showers with a few embedded thunderstorms will likely
persist on Wednesday, including a few strong storms possible near
the Red River as cold front stalls over the ARKLATX region. At least
some break from the excessive heat expected, although a slow warming
trend is still expected Thursday into Friday with humidity levels
increasing.

Another frontal boundary is forecast to move into the area on Saturday
as upper low moves into Great Lakes region. Although there is some
precip timing differences between the GFS/ECMWF, decent rain chances
will persist over the weekend into early next week as boundary stalls
over the area with a series of weak upper level disturbances in zonal
flow aloft. In addition, with the expected cloud cover, high temperatures
should remain a few degrees below normal, which is generally a good
thing mid August.

.AVIATION...
(00Z TAFS)
Issued at 657 PM CDT Tue Aug 16 2022

Scattered showers and thunderstorms will continue to be possible
overnight tonight across much of the CWA as a cold front makes its
way through the CWA and a shortwave drops southeast into the
region. Will continue with Tempo groups for timing of the greater
storm potential tonight/Wednesday. Also overnight
tonight...IFR/MVFR ceilings with additional convection chances are
forecast to spread southward across the CWA with the greater
potential across northeast Oklahoma and northwest Arkansas after
06z. During the day Wednesday...IFR/MVFR ceilings are forecast to
remain common into the afternoon hours before trying to lift back
to high end MVFR/low end VFR ceilings. Precip chances Wednesday
are forecast to shift south and southeast with the greater precip
chances south of Interstate 40 late in the TAF period. Winds
through the period should become north to northeast behind the
frontal passage across eastern Oklahoma while more easterly winds
are forecast through the period for northwest Arkansas.
