THE YEAR 2018 WAS THE FOURTH CONSECUTIVE YEAR OF ABOVE NORMAL
TEMPERATURE (SINCE 2014), THE 6TH WETTEST YEAR ON RECORD, AND THE
5TH OUT OF THE LAST 6 YEARS WITH WELL ABOVE NORMAL SNOWFALL. THE
COLD SPELL TO START THE YEAR SAW THE 4TH LONGEST STRETCH OF ZERO
DEGREE TEMPERATURES ON RECORD WHILE A HEAT WAVE IN JUNE AND JULY
BROUGHT THE 5TH LONGEST STRETCH OF 90 DEGREE HEAT. UNPRECEDENTED
WARMTH IN FEBRUARY, BACK TO BACK SNOWSTORMS IN MARCH, THE LATEST
SUBFREEZING DAY ON RECORD IN APRIL, AND ONE OF THE COLDEST
THANKSGIVINGS ON RECORD WERE JUST A FEW OF THE NOTABLE WEATHER
HIGHLIGHTS OF 2018.

THE YEAR BEGAN IN THE MIDST OF AN INTENSE COLD WAVE THAT HAD BEGUN
ON CHRISTMAS DAY AND INTENSIFIED INTO THE NEW YEAR. THE COLDEST
TEMPERATURE OF THIS COLD WAVE WAS ON JANUARY 2 WHEN THE TEMPERATURE
FELL TO 19 BELOW ZERO. JUST AS THE WORST OF THE COLD STARTED TO
ABATE, A STRONG NOR`EASTER BROUGHT 13 INCHES OF SNOW AND 47 MPH
WINDS CREATING BLIZZARD CONDITIONS ON JANUARY 4. MORE COLD AIR
POURED IN BEHIND THE STORM. WHEN THE COLD SPELL FINALLY BROKE,
CONCORD HAD SEEN 12 STRAIGHT DAYS WITH A TEMPERATURE OF ZERO OR
COLDER, THE 4TH LONGEST SUCH STRETCH ON RECORD.

AFTER NEARLY TWO WEEKS OF BRUTAL COLD, THE JANUARY THAW ARRIVED. THE
TEMPERATURE WARMED INTO THE 50S FOR THREE DAYS FROM JANUARY 11 THRU
13. THIS ALONG WITH MORE THAN AN INCH OF RAIN PUT A DENT IN THE SNOW
COVER WHICH HAD BUILT UP THROUGH THE COLD SPELL. A COLD FRONT ON
JANUARY 13 PUT AN END TO THE THAW WITH THE TEMPERATURE DROPPING FROM
57 DEGREES THAT MORNING ALL THE WAY TO 12 DEGREES BY MIDNIGHT.
ALTHOUGH IT GOT COLD AGAIN BEHIND THIS COLD FRONT, IT WAS A FAR CRY
FROM THE EXTREME COLD SEEN JUST A WEEK EARLIER. IN FACT, ALTHOUGH
CONCORD SAW A FEW MORE BOUTS OF WINTRY SNOW AND ICE, THE TEMPERATURE
BEGAN TO TREND ABOVE NORMAL FROM THE LAST HALF OF JANUARY RIGHT
THROUGH FEBRUARY. THIS GRADUAL WARMING INTENSIFIED DRAMATICALLY IN
THE LAST HALF OF FEBRUARY AS THE TEMPERATURE HIT 60 DEGREES ON 3
DIFFERENT DAYS, INCLUDING 74 DEGREES ON FEBRUARY 21. THIS WAS THE
WARMEST TEMPERATURE EVER OBSERVED IN THE MONTH OF FEBRUARY.

ALTHOUGH THE WARM FEBRUARY SENT SIGNALS OF AN EARLY SPRING, WINTER
HAD OTHER PLANS IN MIND. AN NOR`EASTER BROUGHT MORE THAN 10 INCHES
OF SNOW ON MARCH 7 AND 8, WITH AN EVEN BIGGER SNOWFALL COMING A WEEK
LATER WHEN MORE THAN 17 INCHES WAS RECORDED ON MARCH 13 AND 14. COLD
AIR POURED IN BEHIND THE SECOND STORM BRINGING WINTER-LIKE COLD IN
THE MIDDLE OF MARCH. ALTHOUGH IT BEGAN TO WARM UP AGAIN TOWARD THE
END OF MARCH, THE LATE SEASON SNOW AND COLD WAS ENOUGH TO KEEP THE
WINTER SNOW COVER ON THE GROUND UNTIL THE END OF MARCH FOR THE 5TH
TIME IN THE LAST 6 YEARS. A SERIES OF UPPER LEVEL TROUGHS BROUGHT
COLD AND SHOWERY WEATHER FOR MUCH OF APRIL. THE MOST INTENSE OF THIS
ROUND OF COLD CAME IN MID APRIL WHEN THE TEMPERATURE DID NOT RISE
ABOVE FREEZING ON APRIL 15, WITH SLEET AND FREEZING RAIN FALLING
MOST OF THE DAY. THIS WAS THE LATEST SUBFREEZING DAY ON RECORD AT
CONCORD. HEAVY RAIN MOVED IN THE NEXT DAY AS WARM AIR PUSHED THE
UNUSUALLY INTENSE LATE SEASON COLD AWAY. THE LAST FREEZE OF THE
SEASON CAME ON APRIL 24, ABOUT 3 WEEKS EARLIER THAN NORMAL.

ALTHOUGH THE WARMTH OF SPRING WAS SLOW TO ARRIVE, IT ACCELERATED
INTO SUMMER HEAT IN A HURRY. THE TEMPERATURE HIT 90 DEGREES ON MAY
2, THE EARLIEST 90 DEGREE DAY IN CONCORD SINCE 2009. THE WEATHER
PATTERN HAD SHIFTED FROM A COOL AND WET ONE TO A WARM AND DRY ONE.
NORMALLY SPRING SEES THE MOST FREQUENT RAINFALL OF THE YEAR, BUT NOT
THIS YEAR AS CONCORD SAW ITS 8TH WARMEST AND 10TH DRIEST MAY ON
RECORD. ALTHOUGH THERE WAS A BRIEF PERIOD OF COOL, DAMP, ONSHORE
WINDS AT THE BEGINNING OF JUNE, A SIMILAR PATTERN RESUMED WITH ROUND
AFTER ROUND OF DRY HIGH PRESSURE BUILDING OUT OF CANADA. THIS
BROUGHT WARM DAYS AND COOL NIGHTS UNTIL THE LAST PART OF JUNE.

A LOW PRESSURE SYSTEM BROUGHT MORE THAN AN INCH OF RAIN ON JUNE 28,
THE MOST SIGNIFICANT RAINFALL IN MORE THAN 2 MONTHS. THIS WAS THE
START OF A SHIFT IN THE WEATHER PATTERN AS HOT AND HUMID CONDITIONS
BECAME DOMINANT. CONCORD TOPPED 90 DEGREES FOR 7 DAYS IN A ROW FROM
JUNE 29 THRU JULY 5, THE 5TH LONGEST SUCH STRETCH ON RECORD.

*MOST RECENT OF SEVERAL OCCURRENCES

A FEW COLD FRONTS BROUGHT SOME COOLER WEATHER IN MID JULY, BUT THE
HEAT KEPT RETURNING. ANOTHER PERIOD OF WARM AND HUMID WEATHER BEGAN
IN LATE JULY AS A RIDGE OF HIGH PRESSURE DEVELOPED OVER THE EAST
COAST AND WESTERN ATLANTIC, CONSISTENTLY PUMPING TROPICAL HEAT AND
HUMIDITY INTO NEW ENGLAND. THE HEAT AND HUMIDITY FREQUENTLY BUBBLED
OVER INTO SHOWERS AND THUNDERSTORMS IN THE AFTERNOONS. RAIN WAS
OBSERVED ON 7 STRAIGHT DAYS FROM JULY 22 TO 28 WITH OCCASIONALLY
HEAVY SHOWERS AND STORMS CONTINUING INTO AUGUST. THE HEAVIEST RAIN
CAME ON AUGUST 8 WHEN NEARLY 3 INCHES WAS RECORDED, THOUGH THERE
WERE 6 DIFFERENT DAYS THAT RECORDED MORE THAN AN INCH OF RAIN FROM
LATE JULY THROUGH MID AUGUST. IN ADDITION TO THE FREQUENT HEAVY
SHOWERS, ANOTHER SIGN OF THE PERSISTENT HUMIDITY WAS THE WARM
NIGHTTIME LOW TEMPERATURES, AS HUMID AIR DOES NOT COOL VERY WELL.
FOR 8 STRAIGHT DAYS FROM AUGUST 2 TO 9 CONCORD DID NOT DROP BELOW 65
DEGREES. ALTHOUGH A FEW MORE COLD FRONTS IN SEPTEMBER HELPED TO
OCCASIONALLY PUSH BACK THE WARM AND HUMID WEATHER, THE PERSISTENT
RIDGE OVER THE WESTERN ATLANTIC KEPT BRINGING BACK THE FLOW OF WARM,
MOIST AIR FROM THE TROPICS. THE REMNANTS OF HURRICANE FLORENCE
ROTATED AROUND THIS RIDGE AND PASSED THROUGH NEW ENGLAND ON
SEPTEMBER 18, ALTHOUGH IT ONLY QUICKLY GRAZED CONCORD WITH ALMOST AN
INCH OF RAIN. THE LAST GASP OF SUMMER-LIKE WARMTH WAS IN MID OCTOBER
WHEN CONCORD TOPPED 80 DEGREES ON OCTOBER 9 AND 10.

A COLD FRONT ON OCTOBER 11 BROUGHT ANOTHER INCH OF RAIN BUT MORE
SIGNIFICANTLY USHERED IN A SHIFT IN THE WEATHER PATTERN. A TROUGH
DEVELOPED OVER THE CENTRAL AND EASTERN UNITED STATES BRINGING
SEVERAL ROUNDS OF COLD AIR INTO THE AREA. THE FIRST FREEZE OF THE
SEASON CAME ON OCTOBER 13, ABOUT TWO WEEKS LATER THAN NORMAL AND
ONLY A FEW DAYS AFTER HITTING 80 DEGREES. THIS, COMBINED WITH THE
EARLY LAST FREEZE IN SPRING BROUGHT CONCORD ITS LONGEST GROWING
SEASON ON RECORD.

AS THE NEW PATTERN ESTABLISHED ITSELF WITH A TROUGH OF LOW PRESSURE
OVER THE CENTRAL AND EASTERN UNITED STATES, NEW ENGLAND FREQUENTLY
FOUND ITSELF ON THE EASTERN SIDE OF THE UPPER LEVEL TROUGH. THIS
MEANT THAT STORMS EXITING THE COUNTRY OFTEN TRACKED NEAR THE AREA
BRINGING A NEW ROUND OF PRECIPITATION EVERY FEW DAYS. THE CLOUDY,
WET WEATHER LED TO A LOT OF COOL DAYS AND MILD NIGHTS, BUT EVEN THIS
BEGAN TO CHANGE IN MID NOVEMBER. AFTER ANOTHER INCH OF RAIN ON
NOVEMBER 13, ARCTIC AIR POURED IN BEHIND A COLD FRONT. THE
TEMPERATURE DID NOT GET ABOVE FREEZING AGAIN FOR THE NEXT TWO DAYS.
THE FIRST SNOWFALL OF THE SEASON CAME ON NOVEMBER 15 AND 16 WHEN
MORE THAN 5 INCHES WAS RECORDED. NORMALLY AN EARLY SEASON SNOW SUCH
AS THIS DOES NOT STICK AROUND LONG, BUT A SECOND SNOWSTORM CAME ON
NOVEMBER 19 AND 20 WITH MORE THAN 6 INCHES THIS TIME. EVEN COLDER
AIR POURED IN BEHIND THIS STORM BRINGING MID-WINTER COLD JUST IN
TIME FOR THANKSGIVING. IT WAS THE COLDEST THANKSGIVING SINCE 1873 AS
THE TEMPERATURE FELL TO 6 DEGREES THANKSGIVING MORNING, NOVEMBER 22,
AND ONLY WARMED TO 17 DEGREES THAT AFTERNOON. AFTER SOME MODERATING
TEMPERATURES AT THE END OF NOVEMBER AND BEGINNING OF DECEMBER, ONE
MORE COLD SPELL ARRIVED IN THE FIRST HALF OF DECEMBER. FINALLY,
THOUGH, THE FREQUENT STORMINESS ENDED AS CONCORD WENT 12 DAYS
WITHOUT MEASURABLE PRECIPITATION. WARMER WEATHER BEGAN TO SPILL INTO
THE REGION IN MID DECEMBER. A RAINSTORM ON DECEMBER 21 WAS
ACCOMPANIED BY 60 DEGREE WARMTH AND MELTED OFF THE EARLY SEASON SNOW
COVER JUST BEFORE CHRISTMAS. IT REMAINED A BIT WARMER THAN NORMAL
THROUGH THE END OF THE YEAR, THOUGH SNOW RETURNED AGAIN ON NEW YEARS
EVE WITH 1.7 INCHES RECORDED BEFORE MIDNIGHT.

THE AVERAGE TEMPERATURE FOR THE YEAR WAS 47.7 DEGREES WHICH WAS 1.3
DEGREES ABOVE NORMAL AND THE FOURTH CONSECUTIVE ABOVE NORMAL YEAR.
THE WARMEST YEAR WAS IN 2016 WHEN THE AVERAGE TEMPERATURE WAS 49.3
DEGREES. THE COLDEST WAS IN 1918 WHEN IT WAS ONLY 41.1 DEGREES. THE
FOLLOWING TABLE LISTS THE AVERAGE TEMPERATURES FOR EACH MONTH OF
2018 INCLUDING DEPARTURES FROM NORMAL.

PRECIPITATION FELL ON AUGUST 8 WHEN THUNDERSTORMS DROPPED 2.97
INCHES OF RAIN ON THE CITY CONTRIBUTING TO THE WETTEST AUGUST ON
RECORD. A PROLONGED PERIOD OF STORMY WEATHER ALSO BROUGHT FREQUENT
PRECIPITATION FROM LATE OCTOBER THROUGH NOVEMBER. THE WETTEST YEAR
ON RECORD WAS IN 2008 WHEN 57.99 INCHES OF PRECIPITATION FELL. THE
DRIEST WAS IN 1965 WHEN ONLY 24.17 INCHES WAS MEASURED. THE

SNOWFALL STATISTICS ARE NORMALLY LISTED BY SEASON RATHER THAN BY
CALENDAR YEAR. HOWEVER, 2018 SAW 83.9 INCHES OF SNOWFALL WHICH WAS
22.5 INCHES ABOVE NORMAL. THIS IS THE 5TH OF THE LAST 6 YEARS IN
WHICH CONCORD HAS RECORDED MORE THAN A FOOT ABOVE NORMAL SNOWFALL.
THE HEAVIEST SNOWSTORM WAS ON MARCH 13 AND 14 WHEN 17.1 INCHES FELL.
THERE WERE 19 DAYS WHICH MEASURED AT LEAST 1.0 INCH OF SNOWFALL. AT
LEAST 6.0 INCHES WAS RECORDED ON 4 DAYS IN 2018. THE FOLLOWING TABLE

PERIOD OF BRUTAL COLD. WARM CONDITIONS IN FEBRUARY AND EARLY MARCH
BROUGHT THE SNOW COVER DOWN TO ONLY 1 INCH IN THE FIRST WEEK OF
MARCH, BUT TWO MORE BIG SNOWSTORMS AND MORE COLD AIR BROUGHT SNOW
DEPTH BACK UP TO 18 INCHES AGAIN ON MARCH 14. THE LAST OF THIS SNOW
COVER REMAINED ON THE GROUND UNTIL THE MORNING OF APRIL 1. THE SNOW
SEASON BEGAN EARLY THIS FALL WITH THE FIRST SNOWSTORM ON NOVEMBER
15. MORE SNOW FELL A FEW DAYS LATER AND UNUSUALLY COLD WEATHER KEPT
THIS ON THE GROUND FOR MORE THAN A MONTH. HOWEVER, WARM AND WET
