SPRING STARTED OFF COOLER THAN NORMAL AFTER A STRONG COLD FRONT
CROSSED THE REGION WITH SOME LIGHT SNOW EVENTS THROUGH THE FIRST FEW
DAYS OF MARCH. THE COOL WEATHER QUICKLY TURNED MILD BY THE END OF
THE FIRST WEEK OF MARCH, ALTHOUGH THIS MILD WEATHER WAS INTERRUPTED
BY ANOTHER STRONG COLD FRONT CROSSING ON MARCH 8TH. THIS SET THE
STAGE FOR THE GREATEST SNOWFALL OF THE SPRING SEASON ON MARCH 9TH
WHEN AN AREA OF LOW PRESSURE TRACKED ACROSS SOUTHERN NEW ENGLAND
BRINGING 4.4 INCHES OF SNOW. A WARMING TREND THEN FOLLOW THROUGH THE
MIDDLE OF MARCH AND PEAKED ON THE 18TH WHEN THE HIGH REACHED 72
DEGREES AND THE LAST OF THE WINTER SNOWPACK MELTED. ABOVE NORMAL
TEMPERATURES CONTINUED INTO THE FINAL WEEK OF MARCH BEFORE A STRONG
COLD FRONT CROSSED LATE ON THE 27TH. THIS COLD FRONT BROUGHT A SHOT
OF COLD AIR ON THE 28TH WHEN THE HIGH TEMPERATURE ONLY REACHED 27
DEGREES AND WAS THE LAST TIME THE HIGH TEMPERATURE STAYED BELOW
FREEZING DURING THE SPRING. TEMPERATURES SLOWLY REBOUNDED THROUGH
THE END OF MARCH AND STAYED CLOSE TO NORMAL THROUGHOUT MUCH OF
APRIL. DURING APRIL THERE WAS AN ACTIVE PACIFIC JET STREAM WITH
SEVERAL SYSTEMS CROSSING THE CONUS BRINGING BOUTS OF RAIN TO
CONCORD. ALSO DURING THE MONTH OF APRIL THE NAO STAYED
PREDOMINANTLY NEGATIVE. THE COMPETING INFLUENCES OF MILD PACIFIC AIR
FLOODING THE CONUS WHILE BLOCKING OVER THE NORTH ATLANTIC ASSOCIATED
WITH THE -NAO HELPED TO KEEP TEMPERATURES STEADY WITHOUT ANY WARMS
SPELLS OR COLD SNAPS FOR MUCH OF APRIL INTO EARLY MAY. THE
RELATIVELY WET PATTERN IN APRIL GAVE WAY TO A WARM AND RELATIVELY
DRY PATTERN AFTER THE FIRST FEW DAYS OF MAY. THE CONCORD AREA WENT
10 DAYS WITHOUT MEASURABLE PRECIPITATION FROM MAY 5TH TO MAY 14TH
WHILE TEMPERATURES CLIMBED WELL ABOVE NORMAL PEAKING ON THE 14TH
WHEN THE HIGH REACHED 91 DEGREES. THIS WARM AND DRY PATTERN WAS THE
RESULT OF AN ANOMALOUS RIDGE THAT DEVELOPED OVER NEW ENGLAND FOR
MUCH OF MAY. A COUPLE OF FRONTAL SYSTEMS THEN CROSSED THE AREA
BRINGING SHOWERS AND THUNDERSTORMS AND KNOCKING TEMPERATURES BACK
DOWN CLOSER TO NORMAL FOR FEW DAYS BEFORE WARMTH RETURNED WITH THE
WARMEST DAY OF THE SEASON OCCURRING ON THE 22ND WHEN THE HIGH
REACHED 93 DEGREES. THE RIDGE OF HIGH PRESSURE REDEVELOPED DURING
THE LAST WEEK OF MAY BRINGING WARM AND DRY CONDITIONS TO CLOSE OUT
THE SPRING SEASON.

THE AVERAGE TEMPERATURE FOR SPRING WAS 47.1 DEGREES, WHICH WAS 1.9
DEGREES ABOVE AVERAGE. THE WARMEST SPRING ON RECORD WAS IN 2012 WHEN
THE AVERAGE TEMPERATURE WAS 49.6 DEGREES. THE COLDEST WAS 38.7
DEGREES IN 1956.

A TOTAL OF 10.09 INCHES OF PRECIPITATION FELL, WHICH WAS 0.09 INCHES
BELOW NORMAL. THE HEAVIEST PRECIPITATION FELL ON APRIL 8TH WHEN A
LIQUID EQUIVALENT OF 1.03 INCHES WAS RECORDED. THE DRIEST SPRING ON
RECORD WAS IN 1915 WHEN ONLY 3.61 INCHES WAS MEASURED. THE WETTEST
WAS IN 1983 WITH 18.14 INCHES.

THERE WAS 7.9 INCHES OF SNOWFALL, WHICH WAS 8.2 INCHES BELOW NORMAL.
THE HEAVIEST SNOWFALL FELL ON MARCH 9TH WHEN 4.4 INCHES WAS
MEASURED. THE LEAST SNOWIEST SPRING ON RECORD WAS IN 2021 AND 2010
WHEN ONLY A TRACE WAS MEASURED. THE SNOWIEST WAS 48.2 INCHES IN
1956.
