...no severe thunderstorm areas forecast...
severe thunderstorms appear unlikely across the contiguous united
states on wednesday.
an upper trough will quickly move from the great lakes and oh valley
into the northeast, with primarily zonal flow across the remainder
of the conus through thursday morning. at the surface, a front will
sink south into northern fl, becoming stationary across the northern
gulf of mexico, with western parts of the boundary returning north
weak instability with poor lapse rates aloft are forecast along and
north of the surface front wednesday morning over the southeast, and
lift associated with the upper trough will likely result in a few
thunderstorms mainly from ga into sc through midday. deep-layer
shear will be strong, but marginal instability, strongly veering
low-level flow and minimal heating should result in waning
thunderstorm coverage throughout the day.
