THE MID ATLANTIC AND SOUTHEAST...

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE
CENTRAL HIGH PLAINS...

CORRECTED FOR THUNDER LINE IN WEST

...SUMMARY...
A few strong storms are possible Saturday across portions of the
Southeast and central High Plains.

...Synopsis...
An upper trough axis will remain situated across the Mid Atlantic
providing cool temperatures aloft but with modest midlevel flow,
with attendant cold front extending from the eastern Carolinas into
the central Gulf coast at 18Z. With a moist air mass in place, this
front will provide a focus for storms with locally gusty winds.

Elsewhere, an upper high will exist across much of the western
states and into the southern Plains. Easterly surface flow around an
upper Mississippi Valley high will transport moisture westward into
Colorado, with scattered strong storms possible.

...Southeastern States...
Storms will likely increase along a cold front, aided by heating,
from the eastern Carolinas southwestward into southern MS/AL/GA.
Ample precipitable water content and favorable time of day will
favor a few wet microbursts with shear profiles otherwise
unfavorable for any organized severe threat.

...Central High Plains...
Increasing easterly low-level flow will transport lower 60s F
dewpoints westward into CO, with upslope flow and strong heating
resulting in a cluster of storms. Weak shear aloft but with modest
looping hodographs in the lower levels suggest slow-moving storms
capable of wind or hail, with threat eventually spreading into
western KS during the evening.
