SUMMER HOT WINDS ON THE GREAT PLAINS. 321 
1888, July , Satina , Kansas .—“ The last ten days have been intensely hot 
and the scorching furnace winds since the 26th have nearly ruined the 
corn crop. No longer period of such winds has occurred since August, 
1874. The hot winds of July 26 continuing to August 3 completely ruined 
the corn crop; fields which promised sixty bushels per acre were changed 
to dry fodder during that period.” John H. Gibson, voluntary observer. 
1888, July .—“Hot winds during the last part of July.” State agent, 
Kansas. 
The hot winds of July 24 to 30 were really two distinct 
periods with the same low pressure area. The low pressure 
appeared over Montana on the morning of the 24th, moved 
southeast, and covered the central slope on the 26th and 
27th, after which it moved westward into Utah, and the ba¬ 
rometer rose .20 of an inch on the 28th along the eastern 
slope. On the morning of the 29th the low pressure area 
had moved eastward and covered the central and northern 
slopes, where it remained stationary until the morning of 
the 30th, after which it moved rapidly to the eastward. 
During the prevalence of this low pressure over the eastern 
slope the barometer was above 30 inches over the western 
portions of Oregon and Washington and there was a well 
defined movement of the atmosphere from the Pacific slope 
across the divide toward the low pressure area. On the 29th 
and 30th the high pressure area moved rapidly eastward 
from the Pacific coast and an area of low pressure made its 
appearance over Oregon on the 31st. Cloudless weather 
prevailed over the greater portion of the eastern slope from 
the 24th to the 30th. 
The hot winds during August the 1st and 2d, while ap¬ 
parently a continuation of the preceding periods, were quite 
independent and accompanied the low pressure area which 
was over eastern Oregon on the 31st of July, and which 
moved rapidly eastward, reaching the eastern slope on the 
afternoon of the 1st, where it remained nearly stationary 
for 24 hours and increased in intensity. It then moved 
rapidly to the northeast, but low pressure continued over 
the central slope until the morning of the 4th, when the 
barometer rose to about 30 inches. As the low pressure
