Mesoscale Discussion 1459
NWS Storm Prediction Center Norman OK
0933 PM CDT Fri Jul 07 2023
Areas affected...West-central Oklahoma and Northwest Texas
Concerning...Severe Thunderstorm Watch 460...
Valid 080233Z - 080430Z
The severe weather threat for Severe Thunderstorm Watch 460
continues.
SUMMARY...Wind damage and isolated large hail will continue to be
possible across parts of western and central Oklahoma over the next
few hours. An isolated severe threat may also occur near the Red
River in northwest Texas.
DISCUSSION...The latest high-resolution radar from Oklahoma City has
a severe line segment over western Oklahoma, with a more fragmented
segment in southwest Oklahoma. These two entities are moving
east-southeastward at around 35 knots. The liner MCS is expected to
continue tracking along and north of a quasi-stationary front
located across southern Oklahoma. The airmass along this track is
moderately unstable with MLCAPE estimated near 1500 J/kg by the RAP.
The Oklahoma City WSR-88D VWP has about 30 knots of 0-6 km shear
with some directional shear located in the lowest kilometer. This
environment will likely enable the MCS to continue having a
wind-damage threat late this evening. Isolated large hail could also
occur with the stronger cores. The threat should become more
isolated as the line moves toward the eastern edge of WW 460.
