The storm that had steady updraft strength around 25 ms over Harrison County gave some lead time before low level mesocyclone tightened north of Magnolia on KOAX 0.5 deg SRM. But 3DVAR did not show strong increase in updraft helicity with max value reaching 50 m/s at 2300z. Low level meso has weakened but strong mid level circulation remains at 2312z.
