AFTER A COLD AND SNOWY LATE WINTER, THE WEATHER PATTERN FINALLY
BEGAN TO SHIFT. THE WINTER COLD CONTINUED THROUGH MARCH, BUT THE
PERSISTENT HEAVY SNOWS CAME TO AN END. THE WEATHER BEGAN TO FINALLY
TURN THE CORNER TOWARD SPRING-LIKE TEMPERATURES IN APRIL. ONE FINAL
SNOWSTORM BROUGHT 2.1 INCHES OF SNOW ON APRIL 8 AND 9, BUT BY THE
MORNING OF THE 12 IT WAS ALL GONE AND WARMER TEMPERATURES WERE HERE
TO STAY. TEN OF THE NEXT 11 DAYS ROSE INTO THE 60S OR HIGHER. THE
HEAVIEST RAIN OF THE WHOLE SPRING SEASON FELL ON APRIL 20 AND 21
WHEN 1.25 INCHES OF RAIN FELL. IT ENDED UP BEING ONE OF THE DRIEST
SPRINGS ON RECORD AS MAY CONTINUED THE DRY SPELL. THE WARMING TREND
ACCELERATED IN MAY ALSO, ENDING UP AS THE SECOND WARMEST ON RECORD
WITH NEARLY HALF THE MONTH SEEING TEMPERATURES IN THE 80S. THE FIRST
90 DEGREE DAY OF THE YEAR ARRIVED ON MAY 10 WITH TWO MORE 90 DEGREE
DAYS TO FOLLOW LATER IN THE MONTH.

THE AVERAGE TEMPERATURE FOR THE SPRING WAS 44.7 DEGREES WHICH WAS
RIGHT AT THE NORMAL VALUE. THE COLD MARCH BALANCED WITH THE VERY
WARM MAY TO YIELD A NORMAL SPRING AVERAGE TEMPERATURE. 100 DEGREES
SEPARATED THE HOTTEST AND COLDEST TEMPERATURES OF THE SEASON. THE
HOTTEST TEMPERATURE WAS 92 DEGREES ON MAY 27 AND THE COLDEST WAS 8
DEGREES BELOW ZERO ON MARCH 1. THE WARMEST SPRING ON RECORD WAS IN
2012 WHEN THE AVERAGE TEMPERATURE WAS 49.7 DEGREES. THE COLDEST WAS
IN 1956 AT 38.7 DEGREES.

ANOTHER ILLUSTRATION OF THE VERY WARM MAY WAS THAT 30 OF THE 31 DAYS
IN THE MONTH SAW A TEMPERATURE OF 60 DEGREES OR HIGHER, SOMETHING
THAT HAD NOT OCCURRED SINCE 1999. A TOTAL OF 27 DAYS IN MAY SAW 70
DEGREES OR HIGHER, 14 DAYS TOPPED 80 DEGREES, AND 3 TOPPED 90. THE
FIRST 90 DEGREE READING OCCURRED ON MAY 10, ABOUT THREE WEEKS
EARLIER THAN NORMAL.

THE LAST FREEZE OF THE SEASON OCCURRED ON MAY 14 WHICH IS VERY
CLOSE TO THE NORMAL DATE OF MAY 15.

A TOTAL OF 4.39 INCHES OF RAIN FELL THIS SPRING WHICH WAS 5.95
INCHES BELOW NORMAL AND THE 4TH DRIEST ON RECORD. THE HEAVIEST RAIN
FELL ON APRIL 20 AND 21 WHEN 1.25 INCHES WAS MEASURED. THE DRIEST
