is not large. Four.hfths of the snow
falls In the four months, December,
January February and March. The
average amount is slightly more than
& inches In February and from 10 to D
inches I'm each of the other three
months. The first light snow in the
fall has occasionally occurred In Sep
tember but usually very little snow
falls even in October. Some snow
nearly always falls in April and in IA
few years light snowfalls have oc-
Cured early In May.
The mean annual temperature is be-
tween 46 degrees and 80 degrees. Jan
uary and February are the coolest OF
the months, with mean temperature
slightly below 20 degrees In the north
ern portion, but slightly above 20 de-
grees in most of the section. July is
the warmest month, with mean tenn
peratures between 73 degrees and 76
degrees. August is only about 2 de-
grees cooler. The average range OF
! the mean temperature of the warm
est and coolest months is 55 degrees.
Maximum temperatures from 90 de.
grees to 100 degrees usually occur "a
few times during the warm season.
July, August. and the first decade of
September. Temperatures of 40 de-
grees to ia degrees have occurred "A
! few times but are very unusual. Min
, mum temperatures 20 degrees to %
degrees below zero occur few times
during the cold season, the latter part
of December, January and February.
Occasionally temperatures ten degrees
, lower occur.
The average season has about las
| to | SO days without severe frosts, thai
| is, from about May Sd to September
! 30th. Killing frosts have occurred,
| however, few times as late in the
spring as the last week in May, and
as early in the fall as between the
| 10th and 18th of September.
The prevailing direction of the wind
for the year is from the northwest,
unless influenced by local conditions.
| The wind blows from the south or the
| southeast the greater portion of the
| time during the warm months of June,
| July and August, and, of course, with
more or less frequency during the
rest of the year. From the middle of
| September to the middle of May the
| prevailing wind is from the north
west.
The velocity of the wind has been
recorded carefully at only one station
in the territory, Omaha. The anemo-
meter is located in the Missouri val
ley, and it probably does not fairly
represent the velocity of the wind in
most of the area west of the bluffs
outside of the river valley. This re-
cord indicates that the velocity aver
ages miles per hour at an elevation
of about 100 feet This is probably
from | to miles below the average
out of the river valley at an elevation
of 80 feet above the earth's surface.
In storms, winds of 80 to 80 miles per
hour occur frequently, and velocitieS
as high as 60 or so miles have been re-
corded for short periods of time. This
high wind frequently accompanies a
severe thunderstorm. Tornadoes are
of rare occurrence, although not en-
tirely unknown.
The average relative humidity for
the year is quite regularly near 70
percent, usually a little more in the
southeastern portion and little less
in the western. 1t is, however, fire.
quently low during the afternoon In
= spring or summer; sometimes it Is be
low 20 percent.
The sky is relatively free of clouds
10 to $50 clear days may be expected
from so to 80 cloudy, and the rest OF
the days of the year will be partly
cloudy.
