This is phenomenal bit of spring
weather we are having, according to Fore
cast Official Harmon. He says we are to
have a hot, early, if not blistering norther
to-day and perhaps tomorrow.
In San Francisco yesterday people said
for the first time this year, what hot
day." and people even repeated the old
inquiry, as it hot enough for your" The
thermometer registered II deg. in the City
yesterday afternoon, which was almost I'M
precedented for this time in May. 1t was
not quite hot enough to.dim the apprecia-
ton of the clear, calm and beautiful day,
but still just warm enough to make peo-
pie open doors, loosen clothing and hunt
for cooling beer and soda water.
Yesterday was just about warm enough
for anybody, but to-day promises to be too
hot for most people in Central and Upper
California. Mr.. Harmon says the weather
is likely to break all records to-day. He
expects that in this City the thermometer
will reach 80 deg, and there is no telling
how much higher it will go. The highest
temperature recorded for San Francisco
during the first ten days in May is 81 deg,
which was reached on May 7, 1876, nearly
twenty years ago. So if the temperature
gets above 81 deg. the record will be broken
here.
But the hottest weather and the phe-
nomenal part of this hot wave will be seen
in the Sacramento and San Joaquin
valleys. Mr.. Harmon says that in
Sacramento to : day the norther will
probably send the temperature up to 80
deg. at least. This will be phenome nal
record for Sacramento, too, for the highest
temperature recorded at Sacramento
during the first ten days in May was SO
deg, which was reached on May TO- 1888
The highest temperature for the whole of
the Sacramento Valley during these first
ten days in May was reached at Red Bluff
on May 8. 1884, when the temperature
showed 80 deg.
a while in June or July, but why it comes
along here the 1st of May Mr.. Harmon
does not know. 1t is likely to do consider
able damage through the Sacramento
Valley.
Those same old 'highs" and "lows' are
the cause of all this. We are having a
norther now, partly because there is a
"high" loafing about over Washington
and Oregon, and because there is the coin
''low" is resting over Southern California.
This big. restful high" to the north is
attended by clear skies and very little
wind. This gives the sun chance to heat
the arid plains up there as hot as its alti-
tude will permit. The thigh" is sending
out it's heated air in all directions, includ-
ing the south, and it happens that the
'low" that is now helping play the game
in Southern California is greedily sucking
in this heated air from the north, which
thus sweeps across Northern and Central
California southwark.
The currents, which are pouring sou TIL
ward from the area of high pressure into
the area of low pressure below US are them
selves attended by high barometric pres
sure; and so they keep out of the Sacra-
mento and San Joaquin valleys the cool
sea breezes which otherwise would be pour
ing into these valleys through the Golden
Gate. That is why there was so little wind
in San Francisco yesterday, and that is
why the interior valleys are not being
cooled by winds from the sea. That is the
