1888, July 13, Gibson, Kansas. —“ Hot winds from the southwest on the 
13th.” Chas. M. Bell, voluntary observer. 
This period of hot winds accompanied a low pressure 
area which appeared to the north of Montana on the morn¬ 
ing of July 10 and extended southward to northern Texas 
by the morning of the 13th, with its greatest depth over 
northern Nebraska. After the 13th the low pressure moved 
off to the southeast and filled up. During the development 
and progress of this low pressure area the barometer was 
above 30 inches along the Pacific coast, with cloudy 
weather and rain, and there was a well defined movement 
of the atmosphere from the Pacific slope across the divide 
toward the area of low pressure. The weather was cloud¬ 
less over the central and southeastern slopes. 
1888, July 17 to 19, Parkston, North Dakota. —“ Hot southwest winds July 
17 to 19.” J. J. Swartzy, voluntary observer. 
This period of hot winds accompanied an area of low 
pressure which appeared in the vicinity of Qu’Appelle on 
the morning of the 15th and moved slowly eastward to the 
north of Minnesota on the morning of the 17th and passed 
eastward to the north of the lakes on the 19th. During the 
progress of this low pressure eastward an area of high press¬ 
ure moved southeastward from Oregon and Washington; 
its crest reached Colorado and Wyoming on the 18th and 
covered the entire eastern slope on the 19th. Cloudless 
weather prevailed over the Dakotas and eastern Montana, 
while to the north, east, and south generally cloudy weather 
prevailed, with more or less rain. (See plate 5.)
