DISCUSSION
FOR THE FIRST MONTH SINCE OCTOBER EUREKA SAW BELOW
NORMAL RAINFALL WITH ONLY APPROXIMATELY HALF OF THE NORMAL RAIN
FALLING FOR THE MONTH OF APRIL. FOR THE WATER YEAR THAT STARTED
OCTOBER FIRST, RAINFALL IS STILL ABOVE NORMAL. TEMPERATURES ENDED
THE MONTH BELOW NORMAL ONCE AGAIN, HOWEVER MOST OF THE BELOW NORMAL
TEMPERATURES WERE IN THE FIRST HALF OF THE MONTH. THIS CONTINUES THE
TREND OF BELOW NORMAL TEMPERATURES FOR MUCH OF THE WINTER. ONE OF
THE MORE NOTABLE EVENTS WAS A THUNDERSTORM ON THE 17TH. MUCH OF
EUREKA HEARD THE THUNDER FOR A PERIOD OF AN HOUR OR SO.
