Convective guidance shows that some
isolated convection could
happen within the
warm sector over central GA during the day
Friday, and given that
CAPE values will be within the 500-1000
J/kg range,
SRH values will be 100-200
m2/s2, and 50+
kt of speed
shear will be overspreading the area, both a wind and
tornado
hazard will exist with some transient supercells and bowing
segments possible. The one hang-up could be higher coverage of
rainfall than expected, which could slow the lift of the warm
front and keep any
convection more elevated. Later into the night
and early morning hours, warm
front should move well north, and
ongoing
convection ahead of the approaching cold
front will
likely
become increasingly more surface based. Substantial wind
shear
aloft, decent low level
shear, and surface based
instability will
lead to some bowing line segments and potential QLCS features as
this
convection pushes through out ahead of the cold
front. This
will bring both a severe
wind gust threat alongside the
possibility of a few tornadoes, especially in central Georgia,
which has seen a small segment of central Georgia upgraded to an
enhanced risk for Day 2.
