The Bulletin In Detail.
Washington, d. G., Aug. 3.-Last
bulletin gave forecasts of disturbance
to cross continent tot, warm wave
to s, cool wave 5 to 8. Next disturl
ance will reach the Pacific coast about
| 6, cross west of Rockies country by
| close Z, great central valleys to TO,
eastern states IL. Warm wave will
cross west of Rockies about 6, great
central valleys 8, eastern states 10.
Cool wave will cross west Rockies
about 9, great central valleys II, east
ern states 13.
This will be one of the most severe
disturbances of the month and will
spend it's greatest force west of Meri-
dian so. Temperatures will not go
| high except in the drouth district Of
which Kansas City VIII be central
point. Rains will keep well to north
ward till they have crossed Meridian

central valleys Is, eastern states 18.
This disturbance will bring one of
the hottest periods Of the summer and
the drouth sections will greatly suffer
from the intense heat and evaporation
of moisture.
Showers will probably occur as the
apex of this heat wave passes to east

the southwestern drouth The cool

the excessive heat and the little re
