Areas affected...Southern Lake Michigan into southern lower MI
Concerning...Severe potential...Watch unlikely=20
Valid 122052Z - 122215Z
Probability of Watch Issuance...5 percent
SUMMARY...Isolated hail cannot be ruled out into early evening as
storms move eastward.
DISCUSSION...Elevated convection has recently intensified over
southern Lake Michigan, after earlier producing small hail over
southeast WI. Persistent low-level warm/moist advection will allow a
plume of MUCAPE to expand east-northeastward through the remainder
of the afternoon, with MUCAPE generally increasing into the 500-1000
J/kg range. While this magnitude of MUCAPE is not overly supportive
of large hail, sufficient effective shear will continue to support
storm organization, with small to briefly severe hail and locally
gusty winds possible as storms continue to move eastward into early
evening.
