Using the surface analysis in illustration D049NG below, what weather conditions would you expect to find at position A?

Correct Answer: Option B — Winds NW-W at 15 knots, partly cloudy, and slight seas

Surface analysis charts depict pressure systems and fronts. At position A, the orientation of isobars relative to the low-pressure center indicates a post-frontal environment. Following the passage of a cold front, winds typically shift to the northwest, skies clear, and sea states begin to subside as the system moves.
