FIG. 10. PATHS OF HIGH AND LOW, GREAT SNOW STORM OF JANUARY 27-28, 1922]

This current was steered around the north side of the LOW and met the

north-northeast wind. Under the new conditions the air saturated could

hold only 2 or 3 grams; and so condensation and heavy precipitation

resulted. The region of maximum snowfall was near Washington, and it

will be seen that there is a proportional decrease north and south. The

snowfall at Washington was the heaviest ever known at that city.

Unlike most storms, there was no strong cold northwest wind blowing into

the depression. The temperature rose slowly. It was less a contrast of

winds than a steady slow outward push of the anticyclone, and the

consequent turning of the path of the cyclone eastward.
