THE SNOWY PATTERN THAT DEVELOPED TOWARDS THE END OF WINTER CONTINUED
INTO THE THE FIRST WEEK OF SPRING IN THE MANCHESTER AREA. AS ONE
SYSTEM EXITED ON MARCH 1ST, ANOTHER MORE SIGNIFICANT LOW PRESSURE
SYSTEM TRACKED ALONG THE SOUTHERN NEW ENGLAND COASTLINE MARCH 4TH
THAT BROUGHT 7.7 INCHES OF SNOW. QUIET WEATHER FOLLOWED UNTIL A
STRONG LOW PRESSURE SYSTEM IMPACTED NEW ENGLAND MARCH 13TH INTO THE
MORNING OF MARCH 15TH. THIS SYSTEM BROUGHT SIGNIFICANT SNOWFALL TO
INTERIOR NEW ENGLAND WHILE THE MANCHESTER AREA RECEIVED 9.9 INCHES
FROM THIS SYSTEM, AND WOULD BE THE GREATEST SNOWFALL OF THE SPRING
SEASON. RELATIVELY QUIET WEATHER FOLLOWED WITH THE LAST OF THE
WINTER SNOWPACK MELTING OUT BY THE MORNING OF MARCH 19TH. RELATIVELY
QUIET WEATHER CONTINUED THROUGH THE FIRST HALF OF APRIL WITH A WARM
SPELL AROUND THE MIDDLE OF THE MONTH. THE MANCHESTER AREA ECLIPSED
THE 70 DEGREE MARK FOR THE FIRST TIME OF THE SEASON ON THE 11TH WHEN
THE HIGH TEMPERATURE REACHED 76 DEGREES FOLLOWED BY A HIGH
TEMPERATURE OF 91 DEGREES RECORDED ON BOTH THE 13TH AND 14TH.
THEREAFTER, THE NAO TOOK A DIVE INTO NEGATIVE TERRITORY AS STRONG
AND PERSISTENT OMEGA BLOCK FORMED OVER EASTERN NORTH AMERICA AND THE
NORTH ATLANTIC. THIS BLOCKING PATTERN PERSISTED INTO THE FIRST WEEK
OF MAY THAT LEAD TO MULTIPLE RAIN EVENTS, TEMPERATURES RUNNING BELOW
NORMAL, AND WHEN IT WASN`T RAINING IT WAS OFTEN CLOUDY WITH DRIZZLE.
THERE WERE ALSO DAYS WITH VERY LITTLE VARIATION BETWEEN THE HIGH AND
LOW TEMPERATURE. ALSO DURING THIS PATTERN A SIGNIFICANT RAIN EVENT
OCCURRED ON APRIL 30TH INTO MAY 1ST WHEN A STORM TOTAL OF 1.77
INCHES OF RAIN FELL IN MANCHESTER. ACROSS AREAS NORTH AND EAST OF
MANCHESTER 2 TO 4 INCHES OF RAIN FELL RESULTING IN SOME FLOODING.
THE OMEGA BLOCK THAT PLAGUED THE NORTHEAST FOR THE BETTER PART OF
THREE WEEKS BROKE DOWN BY MAY 6TH. DRY WEATHER FOLLOWED THROUGH THE
MIDDLE OF THE MONTH AND WITH THE EXCEPTION OF A FEW COOL DAYS AND
SEASONABLY COLD NIGHTS, TEMPERATURES TRENDED ABOVE NORMAL. ONE OF
THESE COLD NIGHTS OCCURRED ON MAY 17TH INTO THE MORNING OF THE 18TH
WHEN THE TEMPERATURE FELL TO 28 DEGREES, WHICH WAS THE LAST FREEZE
OF THE SEASON. ANOTHER HEAVY RAIN EVENT OCCURRED MAY 20TH WHEN A
STORM TOTAL OF 1.67 INCHES OF RAIN FELL. A RIDGE OF HIGH PRESSURE
THEN DOMINATED THE WEATHER PATTERN THE LAST WEEK OF MAY RESULTED IN
FAIR WEATHER WITH SOME VERY WARM DAYS INTERMIXED WITH COOLER DAYS
THANKS TO ONSHORE WINDS.
THE AVERAGE TEMPERATURE FOR THE SPRING SEASON WAS 49.3 DEGREES,
WHICH WAS 1.4 DEGREES ABOVE NORMAL. THE WARMEST SPRING ON RECORD WAS
IN 2012 WHEN THE AVERAGE TEMPERATURE WAS 52.4 DEGREES. THE COLDEST
WAS 40.4 DEGREES IN 1967.
A TOTAL OF 12.01 INCHES OF PRECIPITATION FELL, WHICH WAS 1.85 INCHES
ABOVE NORMAL. THE HEAVIEST PRECIPITATION FELL ON APRIL 22ND INTO THE
23RD WHEN 2.20 INCHES OF RAIN FELL. THE WETTEST SPRING ON RECORD WAS
IN 1953 WHEN 18.24 INCHES OF PRECIPITATION FELL. THE DRIEST WAS 3.71
INCHES IN 2015.
HISTORICAL RECORDS AT MANCHESTER BEGAN IN 1885 BUT WITHIN THIS
RECORD THERE REMAINS NUMEROUS YEARS OF UNAVAILABLE DATA. DUE TO
THIS, HISTORICAL RECORDS SHOULD BE CONSIDERED INCOMPLETE AS SOME
SIGNIFICANT EXTREMES MAY BE MISSING FROM THE DATA. MORE CONSISTENT
MODERN RECORDS BEGAN IN 1998 AND CONTINUE TO THE PRESENT.
