COLD WEATHER WAS ABLE TO TAKE HOLD OVER NORTHERN NEW ENGLAND DURING
JANUARY AS A RIDGE IN THE JET STREAM DEVELOPED OVER WESTERN NORTH
AMERICA WITH A DOWNSTREAM TROUGH CENTERED OVER THE GREAT LAKES. THIS
PATTERN ALLOWED FOR SEVERAL INTRUSIONS OF ARCTIC AIR INTO NEW
ENGLAND AS WELL AS A STORM TRACK ALIGNED NEAR THE EAST COAST. THIS
STORM TRACK ALLOWED FOR THREE MODERATE SNOW EVENTS IN THE CONCORD
AREA WITH THE PEAK SNOW DEPTH OF THE YEAR OCCURRING ON JANUARY 30TH
WITH A DEPTH OF 13 INCHES. THE LOWEST TEMPERATURE OF THE YEAR ALSO
OCCURRED ON JANUARY 22ND WHEN THE LOW TEMPERATURE DROPPED TO 10
DEGREES BELOW ZERO. ANOTHER IMPACTFUL WINTER STORM TO AFFECT
NORTHERN NEW ENGLAND UNFOLDED ON FEBRUARY 3RD TO 4TH WHEN A STALLED
FRONTAL BOUNDARY REMAINED DRAPED THROUGH SOUTHERN MAINE AND NEW
HAMPSHIRE WITH WAVES OF LOW PRESSURE TRACKING ALONG THE FRONTAL
BOUNDARY. THE CONCORD AREA WAS ON THE WARM SIDE OF THIS FRONTAL
BOUNDARY WHICH RESULTED IN A MIX OF RAIN, SNOW, AND FREEZING RAIN
WHILE IN THE MOUNTAINS UPWARDS OF 18 INCHES OF SNOW FELL. THIS EVENT
DID RESULT IN THE GREATEST PRECIPITATION OF THE YEAR WITH A LIQUID
EQUIVALENT OF 2.06 INCHES. THE GREATEST SNOWFALL OF THE YEAR
OCCURRED ON FEBRUARY 25TH INTO THE 26TH WHEN 7.4 INCHES WAS MEASURED
IN 24 HOURS AND A STORM TOTAL OF 7.6 INCHES. ADDITIONAL LIGHT
SNOWFALL EVENTS OCCURRED THROUGH EARLY MARCH, BUT ON THE WHOLE
WINTER WENT OUT WITH A WHIMPER WITH THE LAST OF THE WINTER SNOWPACK
MELTING ON MARCH 19TH.

AFTER A SHOT OF COLD AIR AT THE END OF MARCH TEMPERATURES TRENDED
CLOSE TO NORMAL THROUGH APRIL. ON THE WHOLE, APRIL WAS UNEVENTFUL
FOR IMPACTFUL WEATHER WITH PRECIPITATION ALSO TRACKING CLOSE TO
NORMAL, ALTHOUGH NO SNOW OCCURRED. THE LAST FREEZE OF THE SPRING
SEASON OCCURRED ON MAY 11TH WHEN THE LOW TEMPERATURE DROPPED TO 30
DEGREES. THEREAFTER, CONDITIONS TURNED VERY WARM WITH THE FIRST 90
DEGREE DAY OCCURRING ON MAY 14TH WHEN THE HIGH TEMPERATURE REACHED
91 DEGREES. TEMPERATURES THEN AVERAGED WELL ABOVE NORMAL THROUGH THE
END OF SPRING.

THE SUMMER SEASON STARTED OFF COOLER THAN NORMAL WITH A PERIOD OF
BELOW NORMAL TEMPERATURES EARLY IN JUNE. ANOTHER PERIOD OF COOL
CONDITIONS ARRIVED DURING THE THIRD WEEK OF JUNE WHEN AN ANOMALOUS
UPPER LOW SETTLED OVER NEW ENGLAND WITH MEASURABLE SNOWFALL OCCURING
ON MT WASHINGTON ON JUNE 19TH. JUNE WAS ALSO DRY IN THE CONCORD AREA
WITH DROUGHT CONDITIONS EXPANDING AND INTENSIFYING ACROSS NORTHERN
NEW ENGLAND. TEMPERATURES THEN TRENDED WELL ABOVE NORMAL THROUGH
JULY WHILE PRECIPITATION CONTINUED TO RUN BELOW NORMAL FOR THE THIRD
MONTH IN A ROW. THE DOMINANT WEATHER FEATURE WAS A TROUGH OF LOW
PRESSURE OVER EASTERN CANADA THAT OFTEN FAVORED DRY CANADIAN HIGH
PRESSURE SYSTEMS TO MOVE OVER NORTHERN NEW ENGLAND. THIS MADE FOR
VERY WARM AND SUNNY DAYS LEADING TO THE ABOVE NORMAL TEMPERATURES
BEING DRIVEN BY DAY TIME HIGHS. FROM JULY 19TH THROUGH THE 24TH THE
HIGH TEMPERATURE IN CONCORD ECLIPSED THE 90 DEGREE MARK FOR 6
STRAIGHT DAYS. THE TREND IN ABOVE NORMAL TEMPERATURES CONTINUED INTO
AUGUST. FROM AUGUST 2ND TO THE 9TH THE HIGH TEMPERATURE IN CONCORD
ECLIPSED THE 90 DEGREE MARK FOR 8 STRAIGHT DAYS WITH THE HOTTEST DAY
OF THE YEAR OCCURRING ON AUGUST 4TH WHEN THE HIGH REACHED 98
DEGREES. THIS WAS ALSO THE FIRST TIME ON RECORD WHEN THE CONCORD
AREA EXPERIENCED TWO HEAT WAVES WHEN THE HIGH TEMPERATURE EXCEEDED
90 DEGREES FOR AT LEAST 6 DAYS. IN ADDITION TO THE HEAT, AUGUST WAS
ALSO HUMID AS A RIDGE OF HIGH PRESSURE BECAME ESTABLISHED IN THE
WESTERN ATLANTIC AND ADVECTED MOISTURE INTO NEW ENGLAND. DESPITE THE
HUMIDITY IN AUGUST, PRECIPITATION FELL SHORT OF NORMAL FOR THE
FOURTH STRAIGHT MONTH LEADING TO EXPANDING AND INTENSIFYING DROUGHT
CONDITIONS.

THE HEAT GRADUALLY ABATED THROUGH SEPTEMBER WITH MULTIPLE RAIN
EVENTS ALLOWING THE CONCORD AREA TO RECEIVE ABOVE NORMAL RAINFALL
FOR THE FIRST MONTH SINCE APRIL. THE FIRST FREEZE OF THE FALL SEASON
OCCURRED ON SEPTEMBER 30TH WHEN THE LOW TEMPERATURE DROPPED TO 32
DEGREES. A RELATIVE ACTIVE PATTERN DEVELOPED IN OCTOBER AS A RIDGE
OF HIGH PRESSURE DEVELOPED OVER WESTERN NORTH AMERICA WITH A TROUGH
OF LOW PRESSURE OVER THE GREAT LAKES. DESPITE THE ACTIVE PATTERN,
THE CONCORD AREA WAS OFTEN TOO FAR WEST OF THE AXIS OF HEAVIEST
RAINFALL AND PRECIPITATION FINISHED BELOW NORMAL FOR THE MONTH OF
OCTOBER. A PERIOD OF EXCEPTIONAL WARMTH THEN DEVELOPED IN EARLY
NOVEMBER WHEN THE HIGH TEMPERATURE EXCEEDED 70 DEGREES FOR 4
STRAIGHT DAYS FROM NOVEMBER 4TH TO THE 7TH. AFTER THIS PERIOD OF
WARMTH, CONDITIONS TURNED COLDER THAN NORMAL BY MID NOVEMBER WITH
THE FIRST SNOWFALL OCCURRING ON THE 15TH INTO THE 16TH WHEN 0.7
INCHES FELL. SNOWFALL WAS HARD TO COME BY THROUGH THE REST OF
NOVEMBER WHILE TEMPERATURES CONTINUED TO AVERAGE BELOW NORMAL. A
SLOW MOVING LOW PRESSURE SYSTEM TRACKED ACROSS SOUTHERN NEW ENGLAND
INTO THE GULF OF MAINE DECEMBER 16TH AND 17TH THAT BROUGHT A MIX OF
RAIN AND HEAVY WET SNOW TO THE CONCORD AREA WITH A STORM TOTAL SNOW
OF 3.6 INCHES. FURTHER NORTH THIS SYSTEM BROUGHT SIGNIFICANT WET
SNOW ACCUMULATIONS THAT RESULTED IN POWER OUTAGES WITH THE MOUNTAINS
RECEIVING UPWARDS OF TWO FEET OF SNOW. THE LAST SIGNIFICANT WEATHER
MAKER OF THE YEAR OCCURRED ON DECEMBER 22ND AND 23RD WHEN A POWERFUL
LOW PRESSURE SYSTEM DEEPENED OVER THE GREAT LAKES AND TRACKED INTO
QUEBEC. THIS SYSTEM BROUGHT DAMAGING SOUTH TO SOUTHEASTERLY WINDS
WITH THE PEAK GUST AT CONCORD TOPPING OUT AT 51 MPH AND WAS ALSO THE
STRONGEST WIND GUST OF THE YEAR.

THE AVERAGE TEMPERATURE FOR THE YEAR WAS 48.4 DEGREES, WHICH WAS 1.2
DEGREES ABOVE NORMAL AND THE 11TH WARMEST YEAR ON RECORD. THE
WARMEST YEAR WAS 49.3 DEGREES IN 2016. THE COLDEST WAS 1918 AT 41.1
DEGREES.

THE GROWING SEASON, AS DEFINED AS THE LONGEST CONSECUTIVE DAYS ABOVE
FREEZING, LASTED FOR 142 DAYS IN 2022 FROM MAY 11 THROUGH SEPTEMBER
30. THIS IS 4 DAYS SHORTER THAN THE NORMAL OF 146 DAYS. THE LONGEST
GROWING SEASON ON RECORD WAS IN 2021 WITH 180 DAYS. THE SHORTEST WAS
ONLY 86 DAYS IN 1979.

A TOTAL OF 40.74 INCHES OF PRECIPITATION FELL, WHICH WAS 1.21 INCHES
BELOW NORMAL. THE HEAVIEST PRECIPITATION FELL ON FEBRUARY 3RD AND
4TH WHEN WAVES OF LOW PRESSURE TRACKED ALONG A SLOW MOVING COLD
FRONT THAT SLOWLY SANK SOUTH THROUGH NEW ENGLAND BEFORE STALLING
OVER SOUTHERN NEW HAMPSHIRE. THE DRIEST YEAR ON RECORD WAS IN 1965
WHEN ONLY 24.17 INCHES OF PRECIPITATION WAS RECORDED. THE WETTEST
WAS IN 2008 WITH 57.97 INCHES. THE FOLLOWING TABLE LISTS THE
