Thunderstorm development is rapid. A course may become blocked within a short time. When displaying
shorter ranges, periodically select a longer range to see if problems are developing further out. That can
help prevent getting trapped in a blind alley or an area that is closed at one end by convective weather.

examine the areas. Remember to avoid shadowed areas behind targets.
