Areas affected...Central Kansas and Oklahoma
Concerning...Tornado Watch 276...
Valid 290105Z - 290230Z
The severe weather threat for Tornado Watch 276 continues.
SUMMARY...Widely scattered severe storms, including supercells will
continue to pose a risk for severe weather across and east of the
I-135/35 corridors through 9-11 PM.
DISCUSSION...The dryline has retreated some near/west of the
Interstate 135/35 corridors of central Kansas into central Oklahoma.
This boundary remains a focus for continuing thunderstorm initiation
across Kansas, and low-level convergence coupled with cooling aloft
seem to provide some potential for additional new development into
Oklahoma. Otherwise, strongly sheared 40-50 kt southwesterly deep
layer ambient mean flow continues to support initial storm
propagation off the dryline, across and east of the Interstate
135/35 corridors, aided by inflow of strong boundary layer
instability. Storms likely will continue to pose a risk for severe
hail, locally strong surface gusts and perhaps a tornado or two at
least into late evening, before boundary layer instability begins to
wane with the loss of daytime heating.
