...SIGNIFICANT WARMING EARLY AND MID-MONTH, DISMAL END TO APRIL...
THE FIRST HALF OF APRIL FEATURED AN ABUNDANCE OF FANTASTIC DAYS
ACROSS WESTERN NEW YORK AS THE REGION RECORDED A DRY 10-DAY STRETCH
AND LATER IN THE MONTH THREE CONSECUTIVE DAYS IN THE 80S. A DRAMATIC
TURN IN THE WEATHER OCCURRED FOR THE SECOND HALF OF THE MONTH AS
COOL AND WET DAYS BECAME PREDOMINANT. THE WARMTH THROUGH MID-MONTH
CARRIED APRIL TO A TOP 10 WARMEST APRILS ON RECORD, WHILE RAINFALL
ON THE FINAL DAY OF THE MONTH ALSO PUSHED APRIL INTO THE TOP 15
WETTEST APRILS.
THE TEMPERATURE AVERAGED 49.5F DEGREES FOR APRIL, TIED FOR 9TH
WARMEST OF 153 APRILS ON RECORD. HIGHLIGHTS INCLUDE THE THREE DAYS
IN THE 80S ON APRIL 14TH THROUGH 16TH. OUTSIDE OF MARCH 2012, THIS
IS THE EARLIEST 3 CONSECUTIVE 80 DEGREE READINGS IN APRIL ON RECORD.
TWO OF THESE 80 DEGREE READINGS SET DAILY RECORDS, WITH THE 83F
READING ON THE 14TH TYING THE FORMER RECORD OF 83 SET BACK IN 1883,
AND THE 86F READING ON THE 16TH BREAKING THE FORMER RECORD OF 82F
SET BACK IN 2012. ABOVE NORMAL TEMPERATURE DAYS OUTWEIGHED BELOW
NORMAL TEMPERATURE 18 TO 12. OF THESE 18 DAYS, 10 DAYS AVERAGED 10
DEGREES OR GREATER ABOVE THEIR DAILY NORMAL.
PRECIPITATION TOTALED 4.57 INCHES FOR THE MONTH, FINISHING 14TH
WETTEST OF 153 APRILS ON RECORD. ON THE 1ST THE 1.08 INCHES OF
PRECIPITATION SET A NEW DAILY RECORD, BREAKING THE FORMER RECORD OF
0.68 INCHES SET BACK IN 1973. THERE WERE 3 DAYS WITH AT LEAST A HALF
INCH OF PRECIPITATION, ONE MORE THAN NORMAL. FROM THE 6TH TO THE
15TH NO MEASURABLE PRECIPITATION WAS RECORDED. THERE WERE 4 DAYS
THAT RECORDED A TRACE OF SNOW. A TRACE OR MORE OF SNOW HAS FALLEN IN
ALL 140 APRILS OF BUFFALO`S SNOW PERIOD OF RECORD.
APRIL BEGAN WITH A PAIR OF COLD FRONTS, ONE THAT BROUGHT EARLY
MORNING RAIN, AND A SECOND THAT BROUGHT STRONG THUNDERSTORMS ACROSS
WESTERN NEW YORK DURING THE AFTERNOON. ALL TOLD, THE 1.08 INCHES OF
PRECIPITATION SET A NEW DAILY PRECIPITATION RECORD FOR THE 1ST.
SURFACE HIGH PRESSURE BROUGHT FAIR WEATHER ON THE 2ND, THIS PALM
SUNDAY, WHICH WAS THEN FOLLOWED BY CLOUDS AND A WARM FRONT ON MONDAY
THE 3RD. A FEW LIGHT RAIN SHOWERS FELL WITH THE WARM FRONT. ANOTHER
FRONTAL BOUNDARY STALLED OVER THE REGION ON THE 4TH AND 5TH WITH
OVER AN INCH OF RAIN FALLING WITH THIS FRONT. THIS FRONT NUDGED
NORTHWARD SOME ON THE 5TH ALLOWING FOR A BRIEF PERIOD IN THE UPPER
70S BEFORE THE FRONT DROPPED SOUTHWARD AND COOLER LAKE ONTARIO
SOURCED AIR POURED SOUTHWARD ACROSS BUFFALO LATER IN THE DAY. WHILE
A SPRINKLE FELL ON THE 6TH, MUCH DRIER AIR PUSHED INTO THE REGION
AND COMMENCED A BEAUTIFUL, DRY 10-DAY STRETCH OF EARLY SPRING
WEATHER THAT WAS VERY MUCH WARRANTED AFTER A WET START TO SPRING. IN
THIS DRY AIRMASS THE GROUND QUICKLY DRIED OUT AND WITH A SOUTHEAST
WIND TEMPERATURES SOARED TO 83F ON THE 14TH. ON SATURDAY 81F WAS
RECORDED AND SUNDAY WAS THE WARMEST DAY IN THIS STRETCH OF WARM AIR
WITH A READING OF 86F ON THE 16TH. A COLD FRONT ARRIVED LATER THAT
DAY AND BROUGHT SHOWERS AND DAMAGING THUNDERSTORMS, A SUDDEN BURST
OF WIND AND RAINFALL. THIS COLD FRONT ALSO SIGNALED A PATTERN CHANGE
AS ONLY 3 DAYS THE FINAL HALF OF APRIL REMAINED DRY. ON THE 17TH AND
18TH ALONG WITH THE 24TH CONVECTIVE SHOWERS BROUGHT SMALL HAIL AND
GRAUPEL TO THE BUFFALO METRO AREA.
LAKE ERIE`S WATER TEMPERATURE WARMED FROM 38F TO 47F DEGREES BY THE
MONTH`S END. THE 47F DEGREE READING ON THE 26TH WAS THE QUICKEST
LAKE ERIE HAS WARMED TO SUCH A MARK. WINDS WERE NORMAL FOR THE MONTH
AT 10.8 MPH. WITHIN EARLY EVENING THUNDERSTORMS THE WINDS GUSTED TO
59 MPH, WITH THIS THE STRONGEST GUST FOR THE MONTH.
IN ALL, A BEAUTIFUL, WARM MID-APRIL, BUT A DREARY END.
