MD 2002 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR FAR EASTERN ALABAMA AND CENTRAL GEORGIA
Mesoscale Discussion 2002
NWS Storm Prediction Center Norman OK
0327 PM CDT Tue Aug 15 2023
Areas affected…far eastern Alabama and central Georgia
Concerning…Severe potential…Watch unlikely
Valid 152027Z – 152200Z
Probability of Watch Issuance…20 percent
SUMMARY…Strong to occasionally severe thunderstorms will continue
into the evening hours.
DISCUSSION…A line of thunderstorms has developed along a cold
front from central Georgia into far eastern Alabama. A very unstable
airmass is present ahead of these storms with dewpoints in the upper
70s and temperatures in the upper 90s. This has yielded 3000 J/kg
MLCAPE. Effective shear is quite weak (20-25 knots per JGX VWP)
which likely explains both the slow storm speed and outflow dominant
nature of the convection. Thus far, most observation sites have
gusted to 25 to 35 mph as storms have passed although a few stronger
wind gusts of 43/43/56 mph have been observed. Therefore, expect a
continued threat for thunderstorms with isolated damaging wind gusts
through the evening.
