miles. No thunder was heard, and the structure in general was a loose
composite of relatively weak convective cells.
The rain of May 19 took place in an apparently convergent flow in
warm air without being directly associated with identifiable frontal or
squall passages. Radar observations showed no well-developed cells of
strong convection, all echo tops occurring below about 36,000 ft.
Rainfall Intensity
The rainfall-intensity graphs for these two events are
shown in Figs. 7 and 8. Transit of the station by rain-producing cells is
