.PREV DISCUSSION... /ISSUED 0948 AM CST Fri Nov 24 2017/

...South FL...
While thermodynamic profiles will remain conditionally supportive of
thunderstorm development before late afternoon, surface winds have
become increasingly veered late this morning to the west-northwest.
12Z guidance suggests little to no convective development amid
minimal low-level convergence. 700-600 mb temperatures will warm
towards evening as the shortwave impulse off the Space Coast moves
farther east over the Gulf Stream.

...Central MN to Upper MI...
Scant elevated buoyancy with pockets of MUCAPE approaching 100 J/kg
might support a brief thunderstorm. The combination of paltry
buoyancy and moderate frontogenetic forcing for ascent appears
insufficient to warrant delineating an area for 10 percent or
greater thunderstorm coverage.
