Areas affected...Northwest/North-Central GA...Far Northeast AL

Concerning...Severe potential...Watch unlikely 

Valid 031642Z - 031845Z

Probability of Watch Issuance...20 percent

SUMMARY...A few stronger storms capable of damaging wind gusts
and/or isolated hail may occur sporadically over the next few hours.

DISCUSSION...Showers and thunderstorms have recently developed in
the vicinity of a weak surface low and ahead of the broad upper
troughing approaching the area. The air mass is moderately unstable,
promoted by ample low-level moisture and cool mid-level temperatures
(12Z FFC sounding sampled -9 deg C at 500 mb). This region is also
on the southern periphery of slightly stronger upper flow within the
upper trough, contributing to modest vertical shear (despite very
weak low-level flow). A few stronger storms have already been noted,
although updraft strength within these storms quickly waned. That
overall trend is expected to continue, with a more pulse-like storm
mode anticipated. A few of these storms may be able to produce a
water-loaded downburst as the intensity pulses. An isolated instance
or two of hail is also possible.
