MD 0587 CONCERNING SEVERE THUNDERSTORM WATCH 169… FOR NORTH-CENTRAL TO SOUTH-CENTRAL OKLAHOMA
Mesoscale Discussion 0587
NWS Storm Prediction Center Norman OK
0102 AM CDT Wed May 01 2024
Areas affected…north-central to south-central Oklahoma
Concerning…Severe Thunderstorm Watch 169…
Valid 010602Z – 010730Z
The severe weather threat for Severe Thunderstorm Watch 169
continues.
SUMMARY…Severe thunderstorm potential will be focused across
south-central Oklahoma the next couple of hours. Strong gusts to 60
mph are possible.
DISCUSSION…Surface observations over the past 1-2 hours have
showed a considerable drop in surface dewpoints across parts of
central OK (from low/mid 60s F to mid 50s F). This is likely due to
subsidence behind earlier southwest OK storms and low-level
advection of drier boundary-layer air moving into the OKC metro
vicinity. Convection across north-central OK has largely weakened as
outflow has outpaced this activity. For both of these reasons,
severe potential will likely remain limited across the northern
two-thirds of WW 169.
A bowing segment across south-central OK produced a 62 mph gust at
the Ringling OK Mesonet site around midnight local time, with other
measured gusts around 45-50 mph more recently. As this bow continues
east over the next 1-2 hours gusts to 60 mph will remain possible.
Though, gradual weakening is expected with time and eastward extent.
