Mesoscale Precipitation Discussion 0133

Areas affected...northern Georgia

Concerning...Heavy rainfall...Flash flooding likely

Valid 030428Z - 030700Z

Summary...Convective cluster near Atlanta Metro has produced an
axis of 2-3 inches of rainfall, and upstream convection over
east-central Alabama could produce another two inches of rainfall
through 07Z or so.  Flash flooding is likely in this scenario.

Discussion...An earlier convective cluster across northwestern
Georgia gained organization over the past hour while traversing
areas from near Carrollton to southern Atlanta Metro to near
Conyers, producing a narrow band of 2-3 inches of rainfall.  An
impressive 2.41 inch of rainfall was measured in an hour at KATL
with this cluster.  On its current trajectory, that complex should
reach Athens and may continue to produce 1-2 inch/hr rain rates
through 06Z.

Upstream, another cluster of convection (favorably oriented to
fast west-southwesterly steering flow aloft) was producing
localized training and rain rates in the 1-2 inch/hr rain rates. 
That complex should affect areas recently that recently
experienced the 2-3 inch rainfall totals.  It is not out of the
question for some parts of the region to experience 4-5 inch
totals from both complexes through 07Z tonight.

Given recent convective trends, flash flooding appears likely in
this scenario.
