.NEAR TERM...
(Today and tonight)
Issued at 125 AM CDT Wed Jun 18 2025

The quasi-stationary front/outflow boundary produced by tonight`s
thunderstorm complex will be the focal point for additional storm
development today, with the boundary anticipated to be near or just
north/south of the I-40 corridor by early afternoon. With the main
upper vorticity maxima departing with tonight`s activity and a very
subtle secondary shortwave approaching, the activity today and this
evening are expected to be primarily diurnally-driven.

Strong instability (4000+ J/kg), 0-6km bulk shear of 30-40knots,
steep mid-level lapse rates is anticipated just south of the
boundary. Thunderstorms that develop are expected to become severe
with large hail (2+ inches) and damaging wind gusts (60-70 mph)
possible. Effective SRH (150-250 m2/s2) near the boundary could be
sufficient for a brief tornado or two. The severe risk extends into
late evening with storm activity diminishing before midnight.

.SHORT TERM...
(Thursday through Friday night)
Issued at 125 AM CDT Wed Jun 18 2025

The upper ridge then moves over the plains and winds become
predominantly southerly by Thursday with increased south winds on
Friday. Hot and dry conditions are expected.

&&

.LONG TERM...
(Saturday through Tuesday)
Issued at 125 AM CDT Wed Jun 18 2025

Warm, breezy, and dry conditions continue over the weekend. Low
shower and storm chances return early next week as an upper trough
moves over the western CONUS.

.AVIATION...
(12Z TAFS)
Issued at 540 AM CDT Wed Jun 18 2025

Scattered thunderstorms are tracking eastward near I-40 this
morning with some small hail possible, with MVFR ceilings
possible. A surface boundary will drift across the area and is
expected to be south of the OKC metro by this afternoon. Scattered
thunderstorms, some severe, are expected to develop this afternoon
and evening for areas mainly along and east of I-44.
