Mesoscale Discussion 0516
NWS Storm Prediction Center Norman OK
1121 AM CDT Fri May 25 2018
Areas affected...North Texas
Concerning...Severe potential...Watch unlikely
Valid 251621Z - 251845Z
Probability of Watch Issuance...5 percent
SUMMARY...A few strong wind gusts are possible as storms move south
across the area today, but severe weather is not expected.
DISCUSSION...A complex of storms with southward-surging outflow is
currently crossing the Red River into TX. These storms are not
severe as of 16Z, but have produced 30-40 mph wind gusts. Some
increase in intensity is possible this afternoon.
The 12Z FWD sounding shows around 3000 J/kg MUCAPE when modified for
current surface conditions. Although shear profiles are weak, storms
are expected to forward-propagate and maintain and/or increase
slightly. An isolated severe wind gust cannot be ruled out, but
severe coverage is not expected to warrant a watch at this time. In
addition to wind, marginal hail is possible as well given cool
temperatures aloft and substantial instability.
