Squall Line - Honeywell Primus 880 Pilot's Manual

PRIMUSr 880 Digital Weather Radar System
To find a safe and comfortable route through the precipitation area,
study the radar image of the squall line while closing in on the
thunderstorm area. In the example shown in figure 5- 27, radar
observation shows that the rainfall is steadily diminishing on the left
while it is very heavy in two mature cells (and increasing rapidly in a third
cell) to the right. The safest and most comfortable course lies to the left
where the storm is decaying into a light rain. The growing cell on the
right should be given a wide berth.
