... MILD AND WET APRIL ...
THIS YEAR HAS FASHIONED EVERY MONTH MILD TO DATE, AND APRIL WAS NO
EXCEPTION WITH THE AVERAGE TEMPERATURE AGAIN FINISHING WELL ABOVE
AVERAGE. IT WAS ALSO A WET AND SOGGY START TO APRIL WITH
PRECIPITATION FOR THE MONTH WELL ABOVE NORMAL. IT WAS A QUIET MONTH
AS THERE WERE NO STRONG OR SEVERE THUNDERSTORMS IN WESTERN NEW YORK.
THE SPRING WARMTH ENCOURAGED VEGETATION TO BLOOM SEVERAL WEEKS
EARLY, WITH FRUIT TREES AND SPRING FLOWERS PLENTIFUL BY THE END OF
THE MONTH.
THE TEMPERATURE AVERAGED 49.1F FOR THE MONTH. THIS IS 2.3 DEGREES
ABOVE NORMAL, AND IS 19TH WARMEST ON APRIL RECORD. THE FIRST FOUR
MONTHS THIS YEAR HAVE ALL BEEN WELL ABOVE MONTHLY NORMAL
TEMPERATURE. WHEN COMBINED TOGETHER THEY AVERAGE 38.9F WHICH IS THE
WARMEST START TO THE YEAR ON RECORD, TOPPING JANUARY TO APRIL OF
2012 BY A TENTH OF A DEGREE. ONE DAY AFTER THE ECLIPSE, THE
TEMPERATURE SOARED TO 79F ON THE 9TH, TYING WITH 1969 FOR WARMEST
TEMPERATURE FOR THE DATE. THE TEMPERATURE DROPPED TO 29F ON THE
26TH WHICH IS FOUR DAYS BEFORE THE MEAN LAST FREEZE DATE FOR THE
ROCHESTER AIRPORT. HEAVY FROST OCCURRED ON THE MORNINGS OF THE 25TH
AND 26TH.
PRECIPITATION TOTALED 4.35 INCHES WHICH IS TIED FOR 10TH WETTEST ON
RECORD FOR THE MONTH. INCLUDED IN THIS PRECIPITATION THERE WAS 0.9
INCHES OF SNOW ON THE 4TH AND 5TH. THE 16 DAYS WITH MEASURABLE
PRECIPITATION IS 2 MORE THAN A TYPICAL MONTH. THIS IS ALSO JUST THE
FOURTH APRIL ON RECORD WITH TWO DAYS WITH AT LEAST AN INCH OF
PRECIPITATION, THESE BEING THE 3RD (1.19") AND THE 11TH (1.03").
APRIL STARTED WITH A LARGE SYNOPTIC STORM SYSTEM THAT BROUGHT RAIN
SHOWERS ON THE 2ND AND 3RD, TO THEN BE FOLLOWED BY LIGHT SNOW ON THE
4TH AND 5TH. BRIGHT SUNNY SKIES OCCURRED ON THE 7TH, BUT WE WERE
UNABLE TO HOLD ONTO THIS SUNSHINE ON THE 8TH, WHEN MOSTLY TO
COMPLETELY CLOUDY SKIES OCCURRED DURING THE AFTERNOON OF THE
ECLIPSE. ANOTHER SYNOPTIC STORM SYSTEM ADVANCING JUST TO OUR WEST
FROM THE OHIO VALLEY BROUGHT WIDESPREAD RAIN DURING THE 11TH AND
12TH. COMBINED, NEARLY 2 INCHES OF RAIN FELL ACROSS WESTERN NEW YORK
THESE TWO DAYS. THE WEEKEND OF THE 20TH THROUGH THE 22ND FEATURED
MAINLY DRY, BUT COOL CONDITIONS. IN FACT THESE THREE DAYS WERE PART
OF JUST 6 DAYS THAT AVERAGED BELOW THEIR DAILY AVERAGE. AFTER FROSTY
CONDITIONS WITH BEAUTIFUL AFTERNOON SUNSHINE ON THE 25TH AND 26TH,
WARMER AIR FROM THE SOUTH PUSHED INTO WESTERN NEW YORK TO FINISH THE
MONTH WITH SEVERAL DAYS IN THE 60S AND 70S.
WINDS AVERAGED JUST BELOW NORMAL FOR THE MONTH, AND THE STRONGEST
GUST (49 MPH) OCCURRED FROM THE SOUTHWEST ON THE 12TH BEHIND A COLD
FRONT PASSAGE.
IN ALL ANOTHER MILD MONTH THAT STARTED WET, BUT STILL FEATURED
SEVERAL NICE DAYS.
