THE MAIN STORY FOR THE MONTH WAS THE WARM TEMPERATURES IN
EUREKA. TEMPERATURES AVERAGED 4 DEGREES ABOVE NORMAL FOR BOTH
THE HIGH AND THE LOW FOR MONTH. THIS WILL HELPED BY TWO DAILY
RECORD HIGHS OF 65 AND 66 RESPECTIVELY SET ON THE 28TH AND 29TH.
THIS CONTINUES THE TREND OF ABOVE NORMAL MONTHS WITH JUNE BEING
THE LAST MONTH TO SEE BELOW NORMAL TEMPERATURES. THIS MONTH WAS
THE WARMEST AT 4 DEGREES ABOVE NORMAL WHICH IS FAIRLY UNUSUAL FOR
A PLACE THAT FLUCTUATES SO LITTLE ON A DAY TO DAY BASIS. THE
MONTH WAS ALSO FAIRLY WET, HOWEVER IT STILL FELL BELOW NORMAL
BY 0.32 INCHES. THE WATER YEAR SINCE OCTOBER 1ST CONTINUES TO BE
AROUND 1.5 INCHES BELOW NORMAL. THE RAIN WAS RELATIVELY WELL
SPACED OUT THROUGH THE MONTH WITH RAIN FALLING ON 20 DAYS. ON
THE 27TH A STRONG STORM SYSTEM BROUGHT SOUTHERLY WINDS WITH GUSTS
TO 41 MPH. THESE ARE THE STRONGEST WINDS IN EUREKA SINCE MARCH OF
THIS YEAR.
