FREQUENT COOL PERIODS THE FIRST THREE WEEKS OF MAY YIELDED TO ABUNDANT SUNSHINE THE LAST 10 DAYS OF THE MONTH. SUMMER`S WARMTH AND HUMIDITY ALSO INCREASED THE FINAL 10 DAYS OF THE MONTH. PRECIPITATION AGAIN WAS WELL BELOW NORMAL, AND MUCH OF THE PRECIPITATION FELL THE FIRST HALF OF THE MONTH. THE AIR TEMPERATURE AVERAGED 58.9F DEGREES THIS MONTH WHICH IS 2.0 DEGREES ABOVE NORMAL. THERE WERE 12 DAYS THAT AVERAGED BELOW NORMAL IN MAY...WITH ALL DAYS FALLING WITHIN THE FIRST THREE WEEKS OF MAY. BUFFALO REACHED ITS FIRST 80F DEGREE READING ON MAY 12TH...SIX DAYS POST NORMAL. BUFFALO ALSO REACHED ITS FIRST 90F DEGREE READING ON MAY 28TH...WHICH IS THE EARLIEST SUCH READING SINCE 1991. THIS 90F DEGREE READING ALSO ESTABLISHED A NEW DAILY RECORD FOR MAY 28TH...BREAKING THE FORMER RECORD OF 86F SET BACK IN 2012. FOLLOWING THIS FIRST 90F DEGREE READING OF THE YEAR...OVERNIGHT TEMPERATURE ONLY DROPPED TO 69F...SETTING A NEW RECORD WARM MINIMUM TEMPERATURE FOR MAY 29TH. PRECIPITATION AVERAGED WELL BELOW NORMAL AT THE BUFFALO AIRPORT. SPRING`S RAINS FELL LIGHTLY THROUGH THE FIRST HALF OF THE MONTH...WITH THE BULK OF THE RAIN FALLING ON THREE DATES...THE 1ST- 2ND AND 13TH. WHEN COMBINED WITH APRIL...THE TWO MONTH TALLY OF 3.11 INCHES OF PRECIPITATION WAS THE 2ND LOWEST TOTAL SINCE RECORDS MOVED TO THE AIRPORT IN THE SUMMER OF 1943. ON SUNDAY THE 15TH UNDER AN UPPER LEVEL LOW LIGHT SNOW MIXED IN WITH THE RAIN...ENOUGH SNOW THAT A LIGHT DUSTING COVERED THE GROUND. THIS WAS THE FIRST SNOW IN MAY SINCE 2013. THE OVERALL PATTERN THIS MONTH FEATURED A DEEP TROUGH ACROSS THE EAST COAST...AND RIDGE OF HIGH PRESSURE OVER THE WEST COAST. ANOMALOUS POSITIVE HEIGHTS IN THE MID LEVELS OVER GREENLAND FORCED ANY AREAS OF LOW PRESSURE OVER THE EAST TO STALL...WHICH LINGERED COOL DAYS...THAT WERE AT TIMES DAMP THE FIRST HALF OF MAY. THE FIRST AREA OF LOW PRESSURE SPIRALED OVER THE NORTHEAST THE FIRST FEW DAYS OF MAY...BRINGING LIGHT RAIN ACROSS WESTERN NEW YORK. A SECOND LOW FORMED THE SECOND WEEK IN MAY...THIS CLOSER TO THE SOUTHERN MID ATLANTIC REGION. THIS FEATURE WAS FAR ENOUGH AWAY TO LIMIT MUCH PRECIPITATION FROM REACHING THE REGION...THOUGH COOL DAYS PREVAILED. ON THE 14TH A COLD FRONT SWEPT ACROSS THE REGION WITH A FEW RAIN SHOWERS. A MUCH COLDER AIRMASS BEHIND THE FRONT DROPPED ACROSS THE EASTERN GREAT LAKES REGION ON THE 15TH...PRODUCING A FEW SHOWERS OF BOTH RAIN AND SNOW. THIS COOL AIRMASS AND ASSOCIATED TROUGH OF LOW PRESSURE ALOFT SLOWLY EXITED THE REGION THROUGH THE THIRD WEEK IN MAY. FOLLOWING THIS...WARMTH THAT HAD BEEN BUILDING OVER THE WEST BEGAN TO SHIFT EASTWARD. ABOVE NORMAL WARMTH FINALLY REACHED THE EASTERN GREAT LAKES REGION BY THE END OF THE THIRD WEEK OF MAY. THIS WARMTH CONTINUED TO BUILD UNTIL SATURDAY THE 28TH...A DAY THAT FEATURED SEVERAL RECORD HIGH TEMPERATURES ACROSS THE REGION. SEVERAL HEAVY SHOWERS AND THUNDERSTORMS FORMED ON BOTH THE 28TH AND 29TH...THOUGH MUCH OF THE ACTIVITY MISSED THE AIRPORT BOTH DAYS. LAKE ERIE STARTED THE MONTH AT 43F DEGREES AND SLOWLY WARMED THROUGH MID-MONTH. AS SUMMERS WARMTH REACHED THE EASTERN GREAT LAKES REGION THE LAKE TEMPERATURE ROSE DRAMATICALLY THE LAST WEEK OF THE MONTH SKYROCKETING FROM 51F TO 65F THE LAST 9 DAYS OF THE MONTH. WINDS WERE GENERALLY LIGHT THIS MONTH WITH STRONGEST GUSTS OF 47 MPH OCCURRING BEHIND A COLD FRONT PASSAGE ON THE 14TH. IN ALL...AFTER A COOL START TO MAY...SUMMERS WARMTH REACHED THE REGION IN TIME FOR THE MEMORIAL DAY HOLIDAY WEEKEND. SPRING STATS... THE METEOROLOGICAL MONTHS OF MARCH-APRIL-MAY STARTED MILD AND RELATIVELY SNOW FREE. BY EARLY APRIL HOWEVER A RETURN TO LATE WINTER`S CHILL OCCURRED...THIS ALSO ACCOMPANIED BY A FEW INSTANCES OF SNOW. THE APRIL SNOW WAS MORE THAN THE TYPICAL SNOWY MONTHS OF NOVEMBER...DECEMBER AND MARCH...AND WAS THE GREATEST APRIL SNOW SINCE 2004. AFTER A COOL START TO MAY MUCH WARMER TEMPERATURES WERE RECORDED OVER THE FINAL HALF OF THE MONTH. PRECIPITATION WHICH STARTED AROUND NORMAL THROUGH MARCH WAS LACKING THE FINAL TWO MONTHS OF SPRING. THIS LED TO THE GROUND BECOMING DRY...AS SPRING`S VEGETATION QUICKLY USED WHAT WATER WAS STORED FROM EARLY SPRING. TEMPERATURE..............47.3F (+1.7) PRECIPITATION............5.96" (-3.38) SNOW.....................8.0" (-7.9) && THOMAS $$
