THE YEAR 2018 WAS THE THIRD CONSECUTIVE YEAR OF ABOVE NORMAL
TEMPERATURE AND WAS THE FIRST YEAR WITH ABOVE NORMAL PRECIPITATION
SINCE 2014. HOLIDAYS OFTEN SAW EXTREME WEATHER WITH RECORD COLD ON
NEW YEARS DAY, RECORD HEAT ON INDEPENDENCE DAY, AND RECORD COLD ON
THANKSGIVING.

THE YEAR BEGAN IN THE MIDST OF AN INTENSE COLD SPELL THAT HAD BEGUN
ON CHRISTMAS DAY AND INTENSIFIED INTO THE NEW YEAR. THE COLDEST
TEMPERATURE WAS 15 BELOW ZERO ON JANUARY 1, AND AUGUSTA SAW A RECORD
TYING 6 CONSECUTIVE DAYS THAT THE TEMPERATURE DID NOT WARM TO DOUBLE
DIGITS.

AN INTENSE NOR`EASTER ON JANUARY 4 BROUGHT BLIZZARD CONDITIONS AND
MORE COLD AIR POURED IN BEHIND IT. THE TEMPERATURE DID NOT EVEN MAKE
IT TO ZERO DEGREES ON JANUARY 6, THE COLDEST DAY RECORDED SINCE
2004. ALTHOUGH IT SEEMED THE INTENSE COLD WOULD NEVER END, THE
JANUARY THAW WAS JUST AROUND THE CORNER. THE TEMPERATURE WARMED INTO
THE 40S AND 50S JANUARY 11 THRU 13 WITH MORE THAN 2 INCHES OF RAIN
FALLING. THE RAIN AND SNOW MELT CAUSED FLOODING ALONG THE KENNEBEC
RIVER. A STRONG COLD FRONT ON JANUARY 13 BROUGHT THE THAW TO AN END
WITH MORE COLD TEMPERATURES. THIS WAS NOT TO LAST, THOUGH, AS A
WARMING TREND SOON BEGAN WHICH LASTED INTO FEBRUARY. ALTHOUGH THERE
WERE A FEW PERIODS OF COLD AND SNOW, IN GENERAL THE TEMPERATURE WAS
ON ITS WAY UP. IT PEAKED ON FEBRUARY 21 WHEN THE TEMPERATURE HIT 59
DEGREES, THE SECOND WARMEST TEMPERATURE ON RECORD FOR THE MONTH OF
FEBRUARY.

THE WARM WEATHER CONTINUED INTO EARLY MARCH LEADING SOME TO THINK AN
EARLY SPRING HAD ARRIVED. HOWEVER, ABOUT A WEEK INTO MARCH THE COLD
RETURNED AGAIN. TWO NOR`EASTERS BROUGHT HEAVY SNOW ABOUT A WEEK
APART FROM EACH OTHER IN MID MARCH. COLDER AIR MOVED IN BEHIND THE
SECOND ONE WITH THREE CONSECUTIVE SUBFREEZING DAYS. THE COLDEST OF
THE WEATHER ONLY LASTED FOR ABOUT A WEEK BEFORE THINGS RETURNED TO
NORMAL. FOR A FEW WEEKS A SERIES OF UPPER LEVEL TROUGHS OF LOW
PRESSURE BROUGHT IN COLDER AIR FROM CANADA WITH THE SPRING SUN
TRIGGERING AFTERNOON RAIN AND SNOW SHOWERS. THE COLDEST OF THESE
TROUGHS CAME IN MID APRIL WHEN AUGUST DID NOT EVEN WARM ABOVE
FREEZING ON APRIL 15 WITH SLEET AND FREEZING RAIN LEAVING AN ICY
COATING UNCOMMON FOR SO LATE IN THE SEASON. IN FACT IT WAS THE
LATEST SUBFREEZING DAY ON RECORD AT AUGUSTA.

THE EXTREME COLD WAS PUSHED AWAY THE NEXT DAY WITH MORE THAN AN INCH
OF RAIN FALLING AND A TREND TOWARD WARMER WEATHER BEGINNING. THE
LAST FREEZE OF THE SEASON CAME ON APRIL 23. MORE HEAVY RAIN CAME ON
APRIL 25 AND 26 WHEN MORE THAN 2 INCHES FELL, BUT THIS WOULD BE THE
LAST SIGNIFICANT RAINFALL FOR A WHILE AS THE WEATHER PATTERN SHIFTED
FROM COOL AND WET TO WARM AND DRY. BY MAY 2 THE TEMPERATURE WARMED
ALL THE WAY TO 88 DEGREES. A COLD FRONT BROUGHT ENDED THE SUMMER
LIKE HEAT AS QUICKLY AS IT BEGAN, BUT WARM CONDITIONS CONTINUED.
TYPICALLY SPRING WEATHER FEATURES A LOT OF COOL, WET WEATHER AS
WINDS BLOW FROM THE STILL-FRIGID GULF OF MAINE. THIS YEAR WAS
DIFFERENT AS A SERIES OF DRY COLD FRONTS BROUGHT A FLOW OF DRY AIR
OUT OF CANADA. THIS MEANT FREQUENTLY WARM DAYS AND COOL NIGHTS RIGHT
THROUGH THE MIDDLE OF JUNE.

LOW PRESSURE BROUGHT MORE THAN AN INCH OF RAIN ON JUNE 28. THIS WAS
THE FIRST SIGNIFICANT RAINFALL IN TWO MONTHS AND SIGNALED A SHIFT IN
THE WEATHER PATTERN. WARM AND HUMID AIR MOVED IN BEHIND THIS STORM
WITH HEAT AND HUMIDITY CONTINUING THROUGH THE FIRST WEEK OF JULY.
THE TEMPERATURE TOPPED 90 DEGREES FOR THREE CONSECUTIVE DAYS FROM
JULY 3 THROUGH 5, THE FIRST TIME THAT HAS HAPPENED IN AUGUSTA SINCE
2011. A FEW COLD FRONTS BROUGHT OCCASIONALLY COOLER AND DRIER
WEATHER IN MID JULY, BUT THE HEAT AND HUMIDITY RETURNED AGAIN. A
SUBTROPICAL RIDGE OF HIGH PRESSURE OVER THE WESTERN ATLANTIC PULLED
HOT AND HUMID AIR AROUND IT AND INTO NEW ENGLAND BEGINNING IN LATE
JULY. THIS PERSISTED THROUGH AUGUST AND INTO SEPTEMBER WITH ONLY
OCCASIONAL COLD FRONTS ABLE TO BREAK THROUGH THE RIDGE AND PROVIDE
SOME BRIEF COOLER WEATHER. ALTHOUGH THE TEMPERATURE OCCASIONALLY
REACHED 90 DEGREES, THE PERSISTENT HUMIDITY KEPT THE TEMPERATURE
FROM DROPPING MUCH AT NIGHT WITH SEVERAL DAYS THAT DID NOT FALL
BELOW 70 DEGREES. ALTHOUGH MORE SUBSTANTIAL COLD FRONTS BROUGHT A
FEW PERIODS OF COOLER WEATHER, THE OVERALL PATTERN OF WARM, HUMID
CONDITIONS ON THE WESTERN SIDE OF THE SUBTROPICAL RIDGE CONTINUED
THROUGH THE BEGINNING OF OCTOBER.

AFTER WARMING TO 83 DEGREES ON OCTOBER 10 A COLD FRONT BROUGHT SOME
RAIN AND COLDER WEATHER. THIS WAS THE START OF A SHIFT IN THE
WEATHER PATTERN WHICH HAD BEEN STAGNANT THE PREVIOUS FEW MONTHS. A
TROUGH OF LOW PRESSURE DEVELOPED OVER THE CENTRAL AND EASTERN UNITED
STATES WITH FREQUENT ROUNDS OF COLDER AIR MOVING INTO NEW ENGLAND.
THE FIRST FREEZE OF THE SEASON CAME ON OCTOBER 18, ABOUT A WEEK
LATER THAN NORMAL. BEING PREDOMINANTLY ON THE EASTERN SIDE OF THE
UPPER TROUGH MEANT THAT STORM SYSTEMS EXITING THE COUNTRY OFTEN
PASSED NEAR NEW ENGLAND BRINGING NEW PRECIPITATION EVERY FEW DAYS.
EVEN COLDER AIR BEGAN POURING INTO THE REGION IN MID NOVEMBER. AFTER
AN INCH OF RAIN ON NOVEMBER 13, A COLD FRONT MOVED THROUGH AND
BROUGHT AN EARLY SEASON ARCTIC AIR MASS INTO THE AREA. THE
TEMPERATURE DID NOT WARM ABOVE FREEZING FOR TWO DAYS WITH SNOW
OBSERVED ON NOVEMBER 16 AND AGAIN ON NOVEMBER 19 THRU 21. AFTER THE
SECOND SNOWFALL, EVEN COLDER AIR MOVED INTO NEW ENGLAND JUST IN TIME
FOR THANKSGIVING. AFTER DROPPING TO 4 DEGREES ON THANKSGIVING
MORNING, NOVEMBER 22, THE TEMPERATURE ONLY ROSE TO 14 THAT
AFTERNOON. THIS WAS THE COLDEST NOVEMBER DAY ON RECORD.

WHILE THE BRUTAL COLD GRADUALLY MODERATED AT THE END OF NOVEMBER AND
BEGINNING OF DECEMBER, ONE MORE ROUND OF VERY COLD WEATHER WAS IN
STORE. THE TEMPERATURE DID NOT WARM ABOVE FREEZING FOR 9 OUT OF 10
DAYS FROM DECEMBER 4 THRU 13. THIS LONG LASTING COLD SPELL ALSO PUT
AN END TO THE FREQUENT STORMY WEATHER OF THE PREVIOUS SEVERAL WEEKS.
AUGUSTA WENT 14 DAYS WITHOUT MEASURABLE PRECIPITATION FROM DECEMBER
3 TO 16. A SHIFT TO WARMER WEATHER BEGAN IN MID DECEMBER. A
RAINSTORM ON DECEMBER 21 AND 22 BROUGHT NEARLY 2 INCHES OF RAIN AND
TEMPERATURES IN THE 50S.

THE AVERAGE TEMPERATURE FOR THE YEAR WAS 46.1 DEGREES WHICH WAS 0.4
DEGREES ABOVE NORMAL. THE WARMEST YEAR ON RECORD WAS IN 1999 WHEN
THE AVERAGE TEMPERATURE WAS 49.3 DEGREES. THE COOLEST WAS IN 1968
WHEN IT WAS 42.8 DEGREES. THE FOLLOWING TABLE LISTS THE AVERAGE
