NWS Storm Prediction Center Norman OK
0335 PM CDT Mon May 06 2024
Areas affected...Northwest OK
Concerning...Tornado Watch 189...
Valid 062035Z - 062130Z
The severe weather threat for Tornado Watch 189 continues.
SUMMARY...Initial supercell development across northwest Oklahoma
will pose a primary near-term risk for large to very large hail.
Tornado threat should increase rapidly towards 5 to 6 pm.
DISCUSSION...Most prominent convective development on the dryline
south of KS has been in the Ellis county vicinity of northwest OK.
Additional cells should form farther south towards I-40 based on the
agitated CU field noted in the southeast TX Panhandle. These cells
will likely evolve into long-track supercells as they mature with a
primary initial threat of large to very large hail. OK-Mesonet
surface observations confirm the leading edge of upper 60s dew
points are along a line from roughly Tipton to Lahoma. As these
cells impinge on the greater low-level buoyancy and stronger
low-level shear over central OK (per comparison of FDR/TLX/VNX VWP
data), potential for tornadoes will increase substantially during
the early evening. This scenario is supported by recent WoFS
guidance.
