National Weather Service Peachtree City GA
330 PM EDT Tue Jun 14 2022
.SHORT TERM /Tonight through Wednesday Night/...
Environment remains favorable for strong to
isolated severe
thunderstorms this afternoon into the evening hours, especially
for the I-20 corridor southward. 18Z
sounding shows high surface
based
CAPE values of 4000+
J/kg with DCAPE Values around 1200
J/Kg. Mid level lapse rates are more marginal and around 6
C/km.
Areas along and south of Macon to Columbus will be well worked
over, while areas just south of the ATL
metro haven`t been worked
over yet. Models are progging a decrease in coverage and strength
of storms with the loss of heating late this evening.
The environment looks to be as good or better for storms tomorrow.
Mid level lapse rates are even steeper and
CAPE values are 4000+
J/kg. There are some indications within the models of another
MCS
type cluster of storms impacting the
CWA during the afternoon and
evening. With similar conditions today, think storms should
pop
first in the eastern/southern
CWA around the periphery of the high
center in the mid levels.
Before good storm coverage in the east central portion of the
CWA,
started to see some
Heat Index values around 110 degrees. Expect
much the same tomorrow. Went ahead and issued an
Excessive Heat
Watch for portions of east central GA. Later shifts can decide to
upgrade to either an
Excessive Heat Warning/
Heat Advisory. Areas
outside of the Heat
Watch will be in
Heat Advisory, with mountains of
far NE GA the only exception.
