.SHORT TERM...
(This evening through Wednesday)
Issued at 135 PM CDT Tue Jun 4 2024

Main short term focus will storms late this afternoon into the
overnight period, bringing both severe and flooding hazards.

Storms are expected to initiate near a cold front / dryline triple
point in west-central Oklahoma, then expand south and eastward
through the evening. Continued moisture return and at least some
diurnal warming will result in a highly unstable environment; this
combined with adequate deep layer shear (~30 knots 0-6 km bulk
shear) will result in an initial large to very large hail risk. Any
discrete storms along the front will also have a low tornado risk.

Low level shear will initially be low, ramping up with the low level
jet around 00-02z. As storms form into a complex this evening
(transitioning to a heavy rain and damaging wind threat), this will
support MCS maintenance down through south central Oklahoma. This
complex will likely take a similar path to last night`s complex,
hitting areas that are already plenty saturated (1 and 3 hr flash
flood guidance ranges from less than an inch to 2 inches through
this area). Thus, a flood watch will be issued for parts of central
and south central Oklahoma for tonight.

Storms should exit the area by around 4am.

.LONG TERM...
(Wednesday night through next Monday)
Issued at 135 PM CDT Tue Jun 4 2024

With the passage of Tuesday`s cold front, most of the moisture
should be pushed out allowing for a couple of dry days in the
forecast.

Ridging will impinge from the southwest late this week, though that
won`t completely keep out the possibility of northwest flow. Low
rain chances (20-30%) return Thursday night and continue through
early next week, mainly during the overnight periods (it`s MCS
season).

.AVIATION...
(00Z TAFS)
Issued at 639 PM CDT Tue Jun 4 2024

Scattered TSRA still anticipated from near KLAW/KCSM over toward
KOKC/KOUN first few hours of the forecast, with potential for TSRA
to spread south from Kansas toward KPNC and KSWO later this
evening. TSRA expected to grow upscale into MCS mainly south and
east of KOKC and move toward KDUA toward/shortly after 06Z.
MVFR/IFR in and near TSRA through this evening. Mainly VFR with
light northerly winds in wake of TSRA late tonight and tomorrow.
