Mesoscale Discussion 0430
NWS Storm Prediction Center Norman OK
0618 PM CDT Sun Apr 06 2025
Areas affected...Parts of south and central AL into the FL Panhandle
Concerning...Severe potential...Watch unlikely
Valid 062318Z - 070115Z
Probability of Watch Issuance...20 percent
SUMMARY...Some threat for isolated damaging wind and/or a tornado
may persist through the evening.
DISCUSSION...Despite rich boundary-layer moisture and the presence
of 1000-1500 J/kg of MLCAPE, convection has struggled to remain
organized across parts of AL early this evening, possibly due to
generally weak lapse rates and some tendency for storms to be
undercut by outflow. However, deep-layer shear remains favorable for
organized convection, and a persistent 30-40 kt low-level jet is
supporting some enhancement to low-level shear/SRH. One cell near
Montgomery has recently intensified near an outflow boundary, while
an occasionally strong storm cluster persists near/east of Mobile.
There remains some potential for a few cells or clusters to acquire
at least transient organization through the evening, and pose a
threat for locally damaging wind and/or a tornado.
Given the longer-term trends, new watch issuance in the short term
is considered unlikely. However, if trends begin to support more
organized upscale growth or sustained rotating cells, then watch
issuance may become possible.
