...NOT AS COLD...BUT STILL A WET APRIL...

FOLLOWING A HARSH WINTER APRIL 2014 BROUGHT A TYPICAL SPRING-TIME
REGIME TO WESTERN NEW YORK. A FEW TRAILING SNOW SHOWERS...BATTLE OF
WARMTH AND COLD...AND PERIODS OF DRY AND COMFORTABLE SPRING DAYS
MATCHED BY RAINY SPELLS.

THE AVERAGE TEMPERATURE FOR APRIL WAS 46.1F DEGREES WHICH IS A
COUPLE OF TICKS BELOW NORMAL. THERE WERE NO EXTREMES THIS MONTH.
ROCHESTER REACHED ITS FIRST 80 DEGREE READING OF THE YEAR ON THE
13TH WHEN THE TEMPERATURE REACHED 82F. THIS IS ABOUT TWO AND A HALF
WEEKS BEFORE NORMAL.

PRECIPITATION THIS MONTH WAS 3.85 INCHES WHICH IS ABOUT AN INCH
ABOVE NORMAL. PRECIPITATION WAS EVENLY SPREAD THROUGH THE
MONTH. HALF THE DAYS HAD MEASURABLE PRECIPITATION WHICH IS 2 DAYS
MORE THAN NORMAL. HOWEVER OF THESE 15 DAYS...6 HAD MEASURABLE
RAINFALL OF A QUARTER OF AN INCH OR GREATER WHICH IS 2 DAYS MORE
THAN NORMAL. THESE EVENTS WERE ALL UNDER AN INCH FOR EACH CALENDAR
DAY.

THERE WERE TWO DAYS OF LIGHT MEASURABLE SNOWFALL AT THE AIRPORT IN
APRIL. TOTAL FOR THE MONTH WAS 0.3 INCHES...3.6 INCHES BELOW NORMAL.
THIS 0.3 INCHES BROUGHT THE SEASONAL SNOWFALL UP TO 112.7
INCHES...WHICH PLACES 22ND SNOWIEST ON RECORD.

APRIL BEGAN ON A PLEASANT NOTE WITH TEMPERATURES WARMING INTO THE
MID 50S THROUGH THE AFTERNOON AND EVENING...JUST AHEAD OF A COLD
FRONT. THE FIRST STORM SYSTEM OF THE MONTH BROUGHT NEAR A HALF AN
INCH OF RAINFALL ON THE FRIDAY THE 4TH FOLLOWED BY A QUICK DUSTING OF
SNOW SATURDAY MORNING THE 5TH WITHIN A BURST OF GREATER INTENSITY
PRECIPITATION. CLOUDS CLEARED THROUGH THE DAY AND PLEASANT...BUT
COOL CONDITIONS RETURNED ON THE 6TH. ANOTHER STORM SYSTEM RETURNED
RAIN TO THE REGION ON THE 7TH AND 8TH. OUR FIRST STRETCH OF SPRING
BEAUTY OCCURRED FROM THE 10TH THROUGH THE 14TH WITH TEMPERATURES
PEAKING AT 82 ON THE 13TH AND 14TH. THERE WERE A FEW EVENING AND
OVERNIGHT SHOWERS THIS STRETCH...BUT NOT UNTIL LATER ON THE 14TH DID
ANOTHER STORM SYSTEM WITH RAINFALL SWING TEMPERATURES BACK DOWN TO
BELOW NORMAL AND BRING BACK THE APRIL DREARINESS. THE NEAR 40 DEGREE
DROP IN AIR TEMPERATURE ALLOWED FOR A QUICK COUPLE OF TENTHS OF AN
INCH OF SNOW TO ACCUMULATE ON THE 15TH. ANOTHER STRETCH OF DRYNESS
WITH WARMING TEMPERATURES AGAIN FOLLOWED FROM THE 16TH THROUGH THE
21ST. EASTER SUNDAY WAS BEAUTIFUL WITH A FULL DAY OF SUNSHINE. TO
CLOSE THE MONTH A BROAD CUT OFF LOW SPIRALED POCKETS OF HEAVY
RAINFALL ACROSS WESTERN NEW YORK AND BROUGHT A SOGGY END TO THE
MONTH.

WINDS THROUGH THE MONTH AVERAGED CLOSE TO 2 MILES PER HOUR LESS THAN
NORMAL OF ELEVEN AND A HALF. SUNSHINE WAS ABUNDANT THIS
MONTH...WITH 60 PERCENT FACTORING 10 PERCENT MORE THAN NORMAL.

THE COLD WINTER COMBINED WITH A WET AND NORMAL TEMPERATURE APRIL
SLOWED SPRING GROWTH BY AT LEAST A WEEK ACROSS THE AREA.

IN ALL A WET...BUT TRANQUIL APRIL MONTH.
