LOWS, OR AREAS OF WARM, MOIST AIR, CLOUDY
WEATHER, WITH GENERAL RAIN OR SNOW
AND HIGH WINDS
Three such areas affected the weather of the
United States; one of which came from the
Gulf of Mexico and the other two from the
Northwest Territory. Average progressive We
locity eastward 10 miles per hour. Average du-
ration three days.
HIGHS, OR AREAS OF COLD. DRY AIR AND GEN.
ERALLY CLEAR WEATHER, WITH MODERATE
WINDS.
Two such areas affected the weather of the
United States; one came from the North Pa
citic coast, and the other from the Northwest
Territory. Average progressive velocity east
ward II miles per hour Average duration
five days.
Temperdtwe.-The greatest fail in "a hours
l26o) occurred at Moorhead, Mimi, and Spring
field Mo, on the 9th. The greatest rise 1927
occurred at Chicago on the Goth, Pueblo, Colo,
and Kansas City, on the 28th; Fort Buford,
OAK, on the Goth, and Moorhead Mimi, on the
30th The maximum (900) occurred at Yama,
ATiz, on the goth. The minimum (400) &C.
Cured at Bismarck, OAK, and Moorhead,
Mimi, on the GOTH
Precipitation or snow has been report
ed from every State and Territory except Ari-
IONA. The heaviest lover one inch in 2i
hours was reported from Mississippi, Louis
lana, Arkansas and Florida. The maximum in
"a hours ZAP inches) occurred at Key West,
Fla, on the oath and 25th.
Wtnds-Hlgh winds were reported from the
Gulf and Atlantic Coasts, the Ohio, Mississippi
and Missouri Valleys, and the Lake Region.
The highest measured velocity (52 miles per
hour occurred at Cape Hatteras, N. c., on the
2Sth.
Riuers-The maximum rise 600 inches) oc-
Cured at Little Rock, Ark, on the 26th. The

Existing Conditions. i0U is passing east
ward over the Gulf of st. Lawrence, followed
by light snow in new England. Another lou
is central in Dakota, moving eastward, with
light rain. One high is central in Pennsylvania,
and another in Oregon. Generally fair weather,
except as above mentioned
Facts to be Remembered-1 It has been known
for many years that the velocity of Winter
storms is greater than that of Summer, but
careful examination of the velocity of storms
during the past II years in the United States
shows the increase IS regular and unbroken
from September to February, and thence the
decrease is regular to June.
2. The cause for the greater storm velocity
in the United States in Winter may be found
in the greater influx of cold air from British
America, which being dense and heavy descends
rapidly and with great force in the rear of the
advancing lOW, thus augmenting its eastwardly
movement This statement explains the very
high wind velocities in Winter which attend
the movement of highs southeastward over
Montana and Dakota
3. The velocity of the surface winds is less
than that at which storms move, since owing
to friction with the surface of the earth these
winds blow with much less velocity than the
upper air currents. 1t thus follows that the
mean velocity of the transference of storm
conditions on the surface of the earth is not
far from being equal to the mean movement of
the upper currents
