warm wave will be on hand from
May 8 to Z followed by a cold one.
Altogether the first part of the month
says Foster is liable to be warmer
than the season would warrant but
that about the middle cold will pre-
vail. Following is complete fore
cast:
Washington. D. c., May 2.-Last
bulletin gave forecasts of disturbance
to cross continent to 8, warm wave
3 to Z, cool wave to 10. Next dis
turbance will reach Pacific coast
about 8, cross Pacific slope by close
of 8, great central valleys 10 to IL,
eastern states Is. Warm wave will
cross Pacific slope about 8, great cen
trail valleys 10, eastern states 12.
Cool wave will cross Pacific slope
about II, great central valleys Is,
eastern states IL.
During the first half Of May a pro-
gressive rise in temperature, much
greater than the season would indi-
cate, may be expected and this rise
will reach it's zenith little before the
middle Of the month. Severe weather
will begin soon after May 2 and about
seven dangerous storms are expected.
Those who may be inclined to ridi.
Guile the planets as storm makers will
have an opportunity to observe the
effects Of Jupiter, Venus and Mercury
on the weather of May which Is u.s.
ually the most quiet month of the
year. The effects of these planets may
be observed within three days of May
I. These effects will be seen, not on

the vicinity of the storm centers.
I have calculated that the storm
center on May Z would be within 500
miles of Cincinnati at that time a
cool wave center within 800 miles of
Winnipeg, while another cool wave
will be entering the New England
states and another storm center on
the Pacific. slope. Not far from May
these two storm centers and the two
cool waves are expected to greatly
increase in force or intensity, the two
terms meaning the same thing.
The order of movement of weather
disturbances is usually about as l
have stated, there are a rule, being at
all times on the continent moving
eastward, two lows or storm centers,
and two highs or anti-storm centers.
That Is the order of the movement
all around the earth; high following
a low and that low following another
high continuously.
On an average these disturbances
move about 500 miles day and at
present 1 do not expect to forecast
closer than within one day of the
weather events. The weather bureau

be able to accurately fill in that one
day be almost perfect forecasts will
give warnings for longer periods in
advance.
There are some indications of a
severe frost In Manitoba and western
Canada, the Dakotas and other north
western states not far from May 8 and
4 but these indications are not suffic-
iently well marked to enable me to
make a positive prediction.
Very warm weather is expected not
farm from May II and very cool
weather not far from a. Such fore
casts are always made for Meridian
80 and you must count one to three
days later for east of that line and
one to three days earlier for west of
it, always remembering that weather
changes move eastward about 500
miles day.
Severe Storms.
l expect severe storms to occur not
farm from June Is to %; July to
10; September II, 25 and 20; October
9 and %; November and 90; Deem
Der and %. This year will not be
notable for tropical storms Of great
force but Of rather mild type. The
most severe may be expected not far
from OctobG % and November g.
These two asst mentioned dates will
also bring severe storms on the con-
tinent. September II will bring
severe continental storms.
l hope my readers will keep close
watch Of these forecasts of severe
storms, not absolutely severe, but the
most radical of this year. 1 have
much faith in the forecasts of storms
being correct and can bear criticism
I have my system Of forecasting com.
pleted but have not yet used the COM
pleted system in forecasting except
as to the severity Of storms. I am
making ready, as rapidly as possible.
to put my completed work into
general use.
