ABOVE NORMAL TEMPERATURES RETURNED FOR APRIL, WHILE FEATURING A VERY WET MONTH WITH THREE DAILY RECORDING BREAKING PRECIPITATION EVENTS. DESPITE THE WET MONTH, TEMPERATURES FINISHED WITHIN A DEGREE OF THE WARMEST APRIL ON RECORD. THE MARCH-APRIL PRECIPITATION OF 10.74 INCHES WAS THE SECOND WETTEST IN HISTORY, TRAILING ONLY MARCH-APRIL OF 1991 WHICH TOTALED 11.80 INCHES OF PRECIPITATION. THE AVERAGE TEMPERATURE FOR APRIL FINISHED AT 50.5F, WHICH IS THE 6TH WARMEST APRIL ON RECORD, AND 0.8 DEGREES FROM THE WARMEST APRIL ON RECORD (51.3F/1921). THE WARMEST DAY THIS MONTH WAS THE 27TH, WHEN A NEW RECORD HIGH FOR THE DATE WAS SET AT 85F. THIS BROKE THE FORMER RECORD OF 84F SET BACK IN 1984. THIS 85F READING WAS ALSO THE 9TH WARMEST DAY IN BUFFALO`S HISTORY OF RECORD KEEPING. THERE WERE 5 DAYS ABOVE 70F THIS MONTH, ONE MORE THAN THE AIRPORT NORMAL. THERE WERE ONLY 2 DAYS THAT REACHED THE FREEZING MARK THIS APRIL, WITH ONLY THE YEARS 2010 AND 1878 FEWER WHICH FEATURED NO DAYS DIPPING TO THE FREEZING MARK. PRECIPITATION FOR THE MONTH FINISHED AT 6.38 INCHES, WHICH IS THE WETTEST APRIL ON RECORD, AND MORE THAN DOUBLE THE NORMAL AMOUNT OF PRECIPITATION. THE FORMER WETTEST APRIL OCCURRED IN 1961 WITH 5.90 INCHES OF PRECIPITATION RECORDED. CONTRIBUTING TO THIS WET APRIL WERE THREE EXTREME PRECIPITATION EVENTS. THE FIRST, A COMBINATION OF RAIN AND SNOW, WAS ON THE 6TH AND ESTABLISHED A NEW DAILY PRECIPITATION RECORD OF 1.58 INCHES. THE SECOND, ON THE 20TH, FEATURED MULTIPLE THUNDERSTORMS THAT ESTABLISHED NOT ONLY A NEW DAILY RECORD OF 1.95 INCHES, BUT ALSO ESTABLISHED THE GREATEST CALENDAR PRECIPITATION EVENT FOR THE MONTH. THE THIRD EVENT HAPPENED ON THE LAST DAY OF THE MONTH WHEN MORNING THUNDERSTORMS, COMBINED WITH ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS IN THE EVENING BROUGHT 1.07 INCHES OF RAIN AND PUSHED THE AIRPORT TO THE WETTEST APRIL ON RECORD. THERE WAS ONE SNOW EVENT ON THE 6TH AND 7TH WITH 2.3 INCHES OF SNOW FALLING. ALTHOUGH APRIL WAS THE WETTEST MONTH ON RECORD, THE 13 DAYS OF MEASURABLE PRECIPITATION WAS 1 DAY LESS THAN NORMAL. THE SYNOPTIC PATTERN AS A WHOLE THIS MONTH FEATURED A PROGRESSIVE FLOW, WITH ANOMALOUS WARM TEMPERATURES AND INCREASED HEIGHTS ALOFT ACROSS THE NORTHEAST. WHILE THERE WAS ONE AMPLIFIED PERIOD THAT TAPPED INTO MUCH COLDER AIR, WITH ACCUMULATING SNOW ON THE 6TH AND 7TH, MUCH OF THE MONTH FEATURED STORM SYSTEMS TRACKING ACROSS THE OHIO VALLEY, BRINGING PERIODS OF RAIN AND THUNDERSTORMS ACROSS WESTERN NEW YORK. THERE WERE NO PERSISTENT DRY STRETCHES THIS MONTH, WITH JUST THREE DAYS THE GREATEST STRETCH WITHOUT A TRACE OF PRECIPITATION. STORMS THAT BROUGHT ABUNDANT PRECIPITATION TO WESTERN NEW YORK OCCURRED ON THE 3RD-4TH, 6TH-7TH, 19TH-20TH AND 30TH OF THE MONTH. THESE STORM SYSTEM BROUGHT SOME RIVER AND CREEK FLOODING TO THE GENESEE VALLEY ON THE 7TH AND 8TH, WHILE AFTER THE DAILY RECORDING BREAKING EVENT OF THE 20TH SEVERAL CREEKS AND STREAMS THROUGHOUT ALL OF WESTERN NEW YORK WENT INTO MINOR FLOOD STAGE. THE DRIEST WEEK THIS MONTH WAS THE WEEK LEADING UP TO EASTERN SUNDAY THE 16TH, WITH GENERALLY LESS THAN A QUARTER OF AN INCH OF PRECIPITATION FALLING ACROSS WESTERN NEW YORK. THERE WERE FOUR THUNDERSTORMS THIS MONTH WHICH IS DOUBLE THE NORM. SOUTHWEST WINDS AHEAD OF A COLD FRONT BROUGHT THE STRONGEST WIND GUSTS THIS MONTH, WITH 53 MPH REGISTERED AT THE BUFFALO AIRPORT DURING THE AFTERNOON OF EASTER SUNDAY, THE 16TH. OVERALL WINDS WERE NORMAL THIS MONTH, FINISHING JUST A TICK BELOW THE AVERAGE OF 10.8 MPH. LAKE ERIE WARMED QUICKLY HAVING JUST A LITTLE SHORE ICE TO MELT. TEMPERATURES ON THE LAKE ROSE FROM 36F AT MONTHS START TO 48F DEGREES AT MONTHS END. IN ALL ANOTHER VERY WET SPRING MONTH, BUT WITH MILD TEMPERATURES. && THOMAS $$
