JUNE WAS A VERY AVERAGE START TO SUMMER FOR EUREKA. THE MONTH
STARTED WITH AN ANOMALOUSLY STRONG, LATE SEASON ATMOSPHERIC RIVER
WHICH BROUGHT JUST UNDER AN INCH OF RAIN. THOUGH STRONG, THIS EVENT
WAS ISOLATED WITH ONLY LIGHT DRIZZLE OBSERVED THROUGH THE REST OF
THE MONTH. STILL EVEN ON ITS OWN THE SINGLE EVENT MANAGED TO BRING
EUREKA JUST ABOVE AVERAGE PRECIPITATION FOR THE WHOLE MONTH. THE
AVERAGE DAILY TEMPERATURE RANGE FOR THE MONTH WAS JUST 12 DEGREES,
INDICATING STRONG AND CONSISTENT MARINE INFLUENCE. THIS OBSERVATION
IS FURTHER SUPPORTED BY THE NEARLY DAILY OBSERVATION OF FOG A MARINE
STRATUS. SUCH A STRONG MARINE LAYER, BOLSTERED BY HIGH PRESSURE AND
NORTHERLY WIND, IS NORMAL FOR JUNE.
