TOTAL RAINFALL...............  0.04 DEPARTURE FROM NORMAL..... -0.27
TOTAL SINCE JANUARY 1ST...... 27.35 DEPARTURE FROM NORMAL.....  3.58
TOTAL SINCE OCT 1ST.......... 48.07 DEPARTURE FROM NORMAL.....  8.33

HIGHEST SLP......... 30.12 ON 29 LOWEST SLP........29.82 ON 18

...REMARKS...MOST OF THE MONTH`S TEMPERATURES WERE AT OR BELOW
NORMAL. THROUGH MOST OF THE MONTH HIGH TEMPERATURES RANGED FROM ONE
DEGREE ABOVE NORMAL TO 5 DEGREES BELOW NORMAL. THIS WAS MAINLY DUE
TO PERSISTENT HIGH PRESSURE OVER THE WEST COAST AND MODERATE TO
STRONG NORTHERLIES KEEPING THE WATER TEMPERATURES COOL AND THE
MARINE LAYER STRONG. LATE IN THE MONTH AN UPPER LEVEL TROUGH MOVED
OVER THE AREA AND BROKE UP THE MARINE LAYER. WEAK OFFSHORE FLOW
ALLOWED TEMPERATURES TO WARM SEVERAL DEGREES ABOVE NORMAL FOR THE
FIRST TIME IN THE MONTH. TEMPERATURES PEAKED AT 70 DEGREES ON THE
30TH.

DUE TO THE HIGH PRESSURE IN PLACE OVER THE WEST COAST RAINFALL WAS
BELOW NORMAL WITH ONLY 0.04 INCHES OF RAIN FALLING FOR THE MONTH.
THIS RAIN FELL EARLY IN THE MORNING ON THE 28TH. THIS WAS WELL BELOW
THE NORMAL OF 0.31 INCHES...HOWEVER IT IS ACTUALLY QUITE COMMON TO
HAVE LESS RAIN THAN THIS. THIS YEAR RANKS AS ONLY THE 55TH DRIEST
YEAR SINCE 1887. MKK
