ever recorded in the city during the month of February.

inches. North winds at sustained speeds of 20 to 30 mph
with higher gusts persisted throughout the day...producing
much blowing snow. East of the city...winds gusting 40 to
80 mph caused blizzard conditions and produced drifts 2 to
4 feet high.
In 1981...a vigorous cold front at midday produced strong
northeast winds at 20 mph with gusts to 30 mph and billows
of blowing dust reducing the visibility to 3 miles during
the afternoon. Even stronger winds from the north at
