SUMMER HOT WINDS ON THE GREAT PLAINS. 315 
remained over that section until the 14th. It then moved 
slowly southward and reached northern Texas on the morn¬ 
ing of the 16th, after which it moved rapidly eastward. 
Kain fell over the central and southeastern slopes previous 
to the 16.th, but the latter date was cloudless over the south¬ 
eastern slope. During the development and progress of this 
low pressure area the barometer was generally above 30 
inches along the Pacific coast, and the general tendency of 
the atmosphere was from the Pacific, across the divide, to¬ 
ward the low pressure area, with cloudiness and some rain. 
A general depression prevailed from the lakes to northwest¬ 
ern Texas during the latter part of this period, and the 
barometer was rising over the plateau region. 
1886, July 4 to 7, Hamilton County, Nebraska. —“Hot winds.” John 
Ellis, voluntary observer. 
These winds accompanied an area of low pressure which 
appeared over the central portion of the eastern slope on the 
morning of July 2 and moved northward to the northern 
slope and upper Missouri valley on the 4th and 5th, form¬ 
ing a V shaped depression, with its apex over the south¬ 
eastern slope. On the 6th the low pressure moved rapidly 
eastward, and an area of high pressure moved in over the 
northern slope. During the development and progress of 
this area of low pressure the barometer was generally about 
30 inches over the western portions of Oregon and Wash¬ 
ington, with cloudy weather and rain and a well-defined 
tendency of the atmosphere to cross the divide toward the 
area of low pressure. The weather was generally cloudless 
over the central and southeastern slopes.
