Denver with 9.5 inches recorded at Stapleton Airport. North
winds were sustained to 21 mph on the 1st; otherwise winds
were not strong. The air mass was very cold for April.

precipitation of 2.05 inches was the third heaviest of
previous record during April.
In 1959... a cold front produced strong gusty winds across
Metro Denver. North winds gusting to 50 and 60 mph caused
some minor damage to power lines and signs and caused dust
storms on the plains east of Denver. A wind gust to 49 mph
was recorded at Stapleton Airport.

Denver. Heavy snow and high winds combined to close roads...
schools... and airports. Portions of all Interstate highways
out of Denver were closed at times. The snow came after an
exceptionally mild late winter and early spring; trees and
bushes had already bloomed and leafed out. The snow and
wind snapped many of these... causing power outages. Total
snowfall amounts in Metro Denver ranged from 1 to 2 feet
with 2 to 3 feet in the foothills. Snowfall totaled 12.6
inches at Stapleton International Airport where north winds

Denver. The roof of a toy store in Northglenn collapsed.

collapsed in Golden... destroying over a million dollars Worth
