FORECASTS.
Kind of Weather Wyoming VIII Have
This Week.

In his forecasts of Wyoming weather
for this week Foster says:
The changes in weather will occur
in Wyoming within "a hours OF 3 D.. m
Of the dates given below:
March Threatening.
March S-Changeable.
March 9-Cooler.
March 1O-Cool.
March 11-Moderating.
March 12-Warmer.
March 13-Threatening.
My last bulletin gave forecasts of the
storm wave to cross the continent from
the 18th to 18th and the next will reach
the Pacific coast about the 18th, cross
the west Of Rockies country by close OF
18th, great Gentry valleys the Goth &c
22d, eastern states 23d.
The warm wave will CROSS the west
Of Rockies country about the 18th, grea,
central valleys the Goth, eastern states
The 22d.
II IoOl wave Will CIOSS Tic NcSl Vi
Rockies country about the 21st, great
central valleys the 23d. eastern states
the 25th.
This disturbance will cause severe
storms in many parts OF the United
States and a cold wave, causing bliz-
yards in the northwest, will be a part
OF its closing effects.
This will be the "equinoctial Storm
but it must not be supposed that storms
always occur precisely at the equinoxes.
Equinoctial storms may occur at any
time within 10 days of the equinoxes,
the dates being determined by planetary
influences.
The week ending March - will aver
age colder than usual and rainfall for
that period will be above normal. This
forecast, as well as many others in these
bulletins, has special reference to the
whole United States as an average.
Parties interested in greater details
should correspond with me.
February "a brought a great event in
my weather work. On that day | sue
ceeded in reducing to arithmetical fig
ures tie laws that govern he monthly
averages of temperature and rainfall.
These figures prove my long used theory
to be correct and by applying the tables
thus Obtained to the weather records
they prove SO per cent correct, there be-
ing only four errors in SO months.
These four errors belong to the re-
versal periods which l have not yet
been able to reduce to figures, although
their causes are well understood.
Rainfall and temperature constitute
nine-tenths in importance OF all there
is in meterology and at least, after years
of toll, 1 have reduced these to figures
that will always give reliable results.
Hereafter all my forecasts of rainfall
and temperature will be based on these
new tables and will be more reliable
than heretofore.
About four months ago ! succeeded In
reducing 10 figures the short curves
that is. the frequent changes that occur
within the month. Now l have the
monthly averages in figures and these
two tables worked together will give
wonderful results.
The weather feature next in import
ance is the storm waves. l forecas,
them now emphatically. They, too
must be reduced to arithmetical tables. ]
feel confident that l can accomplish this
great work. Following this will, mex
in Importance. be the cold wave and
frosts. Then destructive storms, not In.
Guiding the tornadoes. Sixth will be the
tornado and hail storms, and the last
important feature will be the tropical
hurricanes.
All these will be reduced to arithme-
tical tables based on official weather re-
cords before my system Of m~eteorology
will be complete. There are many other
minor weather features but they are all
governed by the seven grand divisions
in meteOroloey menfioned above
