Valid 261200Z - 011200Z

....DISCUSSION...
A frontal zone will linger along the Southeast coast on Friday. A
few strong storms are possible along this front given the moist
airmass in the region. High pressure and a continental airmass will
build into the eastern CONUS in the wake of this front. This should
result in minimal severe weather potential across much of the CONUS
this weekend and into next week. Operational and ensemble guidance
shows a closed low developing across the Southeast this weekend and
lingering through the middle of next week. Richer moisture may
advect inland to the east and north of this low, and spread
thunderstorms inland, but severe weather chances should still remain
low given weak lapse rates and instability and relatively weak
shear.
