Mesoscale Discussion 0543
NWS Storm Prediction Center Norman OK
0154 PM CDT Sat Apr 27 2024
Areas affected...Northeast OK and southeast KS
Concerning...Tornado Watch 145...146...
Valid 271854Z - 272030Z
The severe weather threat for Tornado Watch 145, 146 continues.
SUMMARY...As severe storms in north-central Oklahoma and
south-central Kansas spread east late this afternoon, an additional
tornado watch will likely be needed.
DISCUSSION...The airmass ahead of severe storms in south-central KS
and north-central OK continues to destabilize as surface temps have
warmed in the upper 70s to low 80s across most of eastern OK into
far southeast KS. While low-level shear within this part of the
warm-moist sector is relatively modest per INX VWP data, it will
strengthen based on upstream TLX data. A mix of discrete and
semi-discrete supercells occasionally embedded within clusters
should spread east-northeast through late afternoon. As this occurs,
all severe hazards will be possible, some of which may be
significant.
