SUMMER HOT WINDS ON THE GREAT PLAINS. 329 
July 30, and on the 31st formed a V shaped area of low 
pressure extending from northern Nevada to Northwest Ter¬ 
ritory. On the morning of August 1 this moved out over 
the eastern slope, the central and northern portions of which 
were covered by this low pressure area during the 1st and 
2d. Afterwards it moved eastward and developed on the 
3d into a trough extending from the lower lakes to western 
Texas. During this time the barometer was slightly above 
30 inches along the coast of Oregon and Washington, 
with generally cloudy weather and a well defined move¬ 
ment of the atmosphere from the Pacific coast across the 
divide toward the area of low pressure. Cloudless weather 
prevailed over the central slope on the 1st and 2d.

wind; very hot and very oppressive.” Jesse Rogers, voluntary observer. 
This period of hot winds accompanied an area of low 
pressure which appeared to the northwest of Montana on 
August 4 and moved southeastward along the eastern slope, 
reaching the northern portion on the 6th and the central 
portion on the 7th, after which it moved rapidly to the 
northeast. During this time there was an area of high 
pressure in the Pacific off the coast of Oregon, with cloudy 
weather over the Pacific coast, and there was a well defined 
movement of the atmosphere across the divide toward the 
low pressure area. Generally cloudless weather prevailed 
over Kansas and Nebraska from the 6th to the 8th. 
1890, August 12, Cunningham, Kansas. —“August 12, hot winds all day.”

appeared to the north of Washington on August 8 and
