Mesoscale Discussion 0523
NWS Storm Prediction Center Norman OK
0512 AM CDT Fri Apr 26 2024

Areas affected...Central into eastern OK

Concerning...Severe Thunderstorm Watch 137...

Valid 261012Z - 261145Z

The severe weather threat for Severe Thunderstorm Watch 137
continues.

SUMMARY...The threat for severe gusts and a couple brief tornadoes
will spread eastward early this morning.

DISCUSSION...A QLCS has recently intensified from central into
southern OK, with a possible QLCS tornado recently noted east of
Norman. The 08Z OUN sounding depicted minimal MLCINH, and similar
surface conditions are noted farther east into
east-central/southeast OK, to the west of an outflow reinforced
boundary across northeast OK.=20

Rather strong low-level shear and SRH were noted on the 08Z OUN
sounding and pre-storm KTLX VWP, and some threat for embedded
mesocyclones and QLCS tornadoes (along with isolated severe gusts)
may spread eastward into the moderately unstable environment
downstream. A small downstream watch issuance is possible within the
hour.
