....DISCUSSION...
Major amplification of the eastern CONUS upper trough appears likely
this weekend, inducing more southerly cyclogenesis across the
North-Central States into the Northeast. A pronounced surface
anticyclone will drive an extensive ridge across the central states,
aiding in progressive cold front movement across the Southeast late
Saturday into Sunday. Ahead of this front, some potential for severe
could yet evolve on D5/Sunday as flow fields strengthen atop a plume
of seasonably rich surface dew points along the eastern Gulf and
South Atlantic Coasts. However, most guidance indicates a fairly dry
frontal passage in this region, amid low RH/weak lapse rates in the
mid-levels.

With a very amplified trough east/ridge west by D6/Monday and a
continental airmass overspreading much of the Gulf, severe potential
should be minimal early next week.
