The overlay and the over-print on the Modified Skew T are very similar. Computa-tions are done the same way on both. These lines are labeled from 350 to 40.
N d is read directly from the point of intersection with the temperature curve.
N w is represented on the grid by black diagonal lines that slope steeply upwards toward the right. Find the mixing ratio line that intersects the dewpoint. From the temperature plot, follow the thin black line, sloping upward to the left to the point where it intersects the mixing ratio line determined in step 1. 3.
