....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE SOUTHEAST AND NORTHERN ROCKIES...

....SUMMARY...
Isolated strong to severe thunderstorms may occur Thursday across
parts of the Southeast and northern Rockies.

....Southeast...
Large-scale upper troughing will continue over much of the eastern
CONUS on Thursday, with a closed upper low remaining over New
England. At the surface, a weak cold front is forecast to shift
southward through the day as an embedded shortwave trough moves
across the TN Valley and Carolinas. Moderate instability and
sufficient deep-layer shear to support organized convection should
be present in a narrow corridor along and just south of the front
across parts of GA into north FL. Multicell clusters capable of
producing damaging winds and some hail may occur as thunderstorms
develop along the boundary and move southward Thursday afternoon and
evening. Some potential for upscale growth into an MCS also appears
possible. Deep-layer shear is forecast to be somewhat weaker farther
west across the Deep South into the lower MS Valley. Have therefore
confined the Marginal Risk to parts of GA into north FL and
vicinity.

....Northern Rockies...
High-based convection should develop Thursday afternoon across parts
of the northern Rockies, on the northern periphery of an upper low
expected to remain over the Great Basin. Although winds through the
troposphere should remain fairly modest, around 20-30 kt of
deep-layer shear should be enough to foster modest convective
organization. A fairly moist low-level airmass, with surface
dewpoints in the mid 50s to low 60s, is also forecast across parts
of eastern WA into northern ID and western MT. As low-level lapse
rates steepen with diurnal heating and weak to moderate instability
develops, convective downdrafts may produce isolated severe wind
gusts.
