2.8 DEGREES WARMER THAN NORMAL.
THE WARM YEAR WAS HIGHLIGHTED BY CONCORD EXPERIENCING ITS WARMEST
SPRING EVER. THE AVERAGE TEMPERATURE FOR THE METEOROLOGICAL SPRING,
MARCH THROUGH MAY, WAS 49.7 DEGREES. THIS WAS 5.0 DEGREES ABOVE
NORMAL AND TOPPED THE OLD RECORD WARMEST SPRING OF 49.2 DEGREES
WHICH WAS SET IN 1921 AND AGAIN IN 2010.
ALL THREE SPRING MONTHS WERE ABOVE NORMAL, BUT IT WAS MARCH
THAT HAD THE BIGGEST IMPACT. CONCORD HAD ITS WARMEST MARCH IN
THE PAST 144 YEARS WITH AN AVERAGE TEMPERATURE OF 42.1 DEGREES.
THIS WAS AN AMAZING 9.0 DEGREES ABOVE NORMAL.
NOT SURPRISINGLY CONCORD SET SEVERAL RECORD HIGH TEMPERATURES IN
MARCH. IN FACT, THERE WERE SEVEN DAYS WITH RECORD HIGHS INCLUDING
FIVE IN A ROW FROM THE 18TH THROUGH THE 22ND. ALSO, THE HIGH FOR
THIS FIVE DAY STRETCH REACHED 80 DEGREES OR WARMER EACH DAY.
BEFORE THIS STRETCH OF WARM WEATHER THE MOST CONSECUTIVE DAYS WITH
HIGHS OF 80 OR WARMER IN CONCORD DURING THE MONTH OF MARCH IS JUST
TWO. CONCORD REACHED 80 OR WARMER ON MARCH 28TH AND 29TH IN 1945
AND ON MARCH 30TH AND 31ST IN 1998.

OF 90 OR WARMER WHICH WAS 6 DAYS MORE THAN NORMAL FOR A YEAR. THERE
WERE ONLY FOUR DAYS WITH LOWS OF ZERO OR COLDER...THREE LESS THAN

INCHES /1.99 INCHES/ OF RAIN ON THE 29TH AND 30TH.
