NWS Storm Prediction Center Norman OK
0733 PM CDT Tue Sep 19 2023
Areas affected…portions of central Oklahoma
Concerning…Severe Thunderstorm Watch 686…
Valid 200033Z – 200200Z
The severe weather threat for Severe Thunderstorm Watch 686
continues.
SUMMARY…A few supercells are approaching the I-35 corridor in
Oklahoma which may necessitate an watch expansion.
DISCUSSION…A left-moving supercell has produced multiple reports
of quarter to golf ball sized hail across southwest Oklahoma with
one report of 2 inch hail in Roosevelt. The environment remains
unstable ahead of this storm and should maintain its intensity to at
least I-35. In addition, another supercell has developed in Canadian
county and recently had a report of 1 inch hail. As both of these
storms approach central Oklahoma, an areal expansion of watch 686
will likely be needed.
