AVOID BOW–SHAPED LINE OF ECHOES BY 20 MILES
Sometimes a fast moving, broken to solid thunderstorm line becomes
bow–shaped, as shown in figure 5–46. Severe weather is most
likely along the bulge and at the north end, but severe weather can
occur at any point along the line. Bow–shaped lines are particularly
disruptive to aircraft operations because they are broken to solid and
can accelerate to speeds in excess of 70 knots within an hour.
