THE YEAR 2017 WAS WARMER AND WETTER THAN NORMAL. IT FEATURED A VERY
WARM JANUARY, A MARCH BLIZZARD, A COLD SPRING, A WARM FALL, HEAVY
RAINS AND WINDS IN OCTOBER, AND A VERY COLD DECEMBER.

THE YEAR STARTED OUT WITH SOME WARMER THAN NORMAL WEATHER. ALTHOUGH
A COLD FRONT ON JANUARY 5 BROUGHT A FEW DAYS OF COLD WEATHER, THE
JANUARY THAW COMMENCED SOON AFTER WITH THE TEMPERATURE PEAKING AT 52
DEGREES ON JANUARY 11. ALTHOUGH THERE WERE A FEW MORE PERIODS OF
COLD AND WINTRY PRECIPITATION, THE WARM TREND CONTINUED INTO
FEBRUARY. IN MID FEBRUARY A REMARKABLY COLD AND SNOWY STRETCH OF
WEATHER WAS OBSERVED. SNOW WAS OBSERVED ON 11 STRAIGHT DAYS FROM
FEBRUARY 6 THRU 16 ALONG WITH SOME COLD TEMPERATURES. BUT ONCE THIS
SNOWY WEATHER ENDED, THE WARMTH RETURNED AGAIN IN A HURRY. THE
TEMPERATURE TOPPED 45 DEGREES FOR 9 STRAIGHT DAYS FROM FEBRUARY 22
THRU MARCH 2, INCLUDING 4 STRAIGHT DAYS IN THE 50S IN LATE FEBRUARY.

A COLD FRONT ON MARCH 2 BROUGHT MUCH COLDER AIR INTO THE AREA WITH 3
STRAIGHT DAYS WITH LOW TEMPERATURES IN THE SINGLE DIGITS. ALTHOUGH
THE TEMPERATURE WARMED UP TO 50 AGAIN ON MARCH 8, THE COLD QUICKLY
RETURNED. THE TEMPERATURE DID NOT WARM ABOVE FREEZING FOR 7 STRAIGHT
DAYS FROM MARCH 10 THRU 16, WITH A SIGNIFICANT SNOWSTORM BRINGING
HEAVY SNOW AND 61 MPH WINDS CREATING BLIZZARD CONDITIONS ON MARCH
14. ALTHOUGH THE EXTREME COLD GRADUALLY LESSENED, THE COLDER THAN
NORMAL WEATHER CONTINUED INTO EARLY APRIL WHEN ANOTHER SNOWSTORM
ARRIVED ON APRIL 1. THIS ULTIMATELY PROVED TO BE THE LAST GASPS OF
WINTER AS MUCH WARMER WEATHER SOON ARRIVED. BUILDING WARMTH IN THE
CENTER OF THE COUNTRY BEGAN OCCASIONALLY SPILLING INTO NEW ENGLAND.
THE TEMPERATURE HIT 70 DEGREES ON APRIL 10 AND 79 DEGREES THE NEXT
DAY. NOT TO BE OUTDONE, IT WARMED TO 81 DEGREES ON EASTER SUNDAY,
APRIL 16. SPRING BECAME A BATTLE BETWEEN THE BUILDING WARMTH IN THE
INTERIOR OF THE COUNTRY AND THE COOL, MOIST INFLUENCE OF THE GULF OF
MAINE. FOR SEVERAL WEEKS MOST DAYS WERE COOL WITH FREQUENT LIGHT
RAINFALL, BUT THE WARM AIR MADE PERIODIC BREAK THROUGHS. THE LAST
FREEZE OF THE SEASON CAME ON APRIL 19, JUST A FEW DAYS LATER THAN
NORMAL. RAIN WAS OBSERVED ON 10 OUT OF 12 DAYS FROM APRIL 30 THRU
MAY 11. A FEW OF THE WARMER BREAKS INCLUDED 79 DEGREES ON APRIL 29
AND 93 DEGREES ON MAY 18 (THE HOTTEST TEMPERATURE OF 2017).

BY THE MIDDLE OF JUNE THE WARMER PERIODS BECAME MORE FREQUENT AND
LONG LASTING. A MINI HEAT WAVE BROUGHT TWO DAYS OF 90 DEGREE HEAT ON
JUNE 11 AND 12, SIGNALING THAT THE WARM AIR WAS WINNING THE BATTLE.
THE MOST SUSTAINED WARMTH OF THE SUMMER CAME IN MID JULY WHEN THE
TEMPERATURE REACHED 80 DEGREES OR WARMER ON 6 OUT OF 7 DAYS FROM
JULY 16 THRU 22. THE LAST HALF OF THE SUMMER SAW SEVERAL DRY AIR
MASSES MOVE IN, ALLOWING TEMPERATURES AT NIGHT TO FALL BELOW NORMAL
WHILE DAYTIME HIGH TEMPERATURES WERE OFTEN NEAR NORMAL. A COLD FRONT
ON AUGUST 18 BROUGHT MORE THAN AN INCH OF RAINFALL, THE MOST
RAINFALL OBSERVED IN WHAT WOULD OTHERWISE BE A DRY SUMMER. COOLER,
FALL-LIKE TEMPERATURES WERE OBSERVED FOR THE LAST WEEK OF AUGUST AND
INTO THE FIRST FEW DAYS OF SEPTEMBER.

AFTER A FEW COOL DAYS IN EARLY SEPTEMBER AND SOME BENEFICIAL
RAINFALL, A NEW WEATHER PATTERN EMERGED FEATURING A RIDGE OF HIGH
PRESSURE OVER THE WESTERN ATLANTIC. THIS ALLOWED WARM, OFTEN HUMID
CONDITIONS TO MOVE UP INTO NEW ENGLAND FOR MUCH OF THE FALL. THIS
WARMTH PEAKED IN LATE SEPTEMBER WHEN THE TEMPERATURE TOPPED 85
DEGREES FOR 4 STRAIGHT DAYS FROM SEPTEMBER 24 THRU 27. ALTHOUGH THE
SUMMER-LIKE WARMTH DID NOT RETURN, THE OVERALL WARM TREND CONTINUED
THROUGH OCTOBER. A FEW PERIODIC COLD FRONTS WOULD BRING BRIEFLY
COOLER WEATHER, BUT THE WARMTH WOULD KEEP RETURNING. IT ENDED UP
BEING THE WARMEST OCTOBER ON RECORD AT AUGUSTA. THINGS BEGAN SHOWING
SIGNS OF CHANGE AT THE END OF OCTOBER. TWO STRONG LOW PRESSURE
SYSTEMS BROUGHT HEAVY RAINFALL IN THE LAST WEEK OF OCTOBER. THE
FIRST BROUGHT MORE THAN 5 INCHES OF RAIN ON OCTOBER 24 THRU 26. THE
SECOND BROUGHT MORE WIND THAN RAIN WITH MORE THAN 1.5 INCHES OF RAIN
AND WINDS GUSTING TO 60 MPH ON OCTOBER 29 AND 30. THESE STRONG WINDS
CAUSED SIGNIFICANT DAMAGE IN THE AREA WITH SOME POWER OUTAGES
CONTINUING THROUGH HALLOWEEN.

ALTHOUGH FALL WARMTH CONTINUED INTO THE FIRST FEW DAYS OF NOVEMBER,
COLDER WEATHER WAS ON ITS WAY. A COLD FRONT ON NOVEMBER 6 BROUGHT
THE FIRST SURGE OF COLDER AIR, WITH AUGUSTA OBSERVING ITS FIRST
FREEZE OF THE SEASON ON NOVEMBER 7, ABOUT A MONTH LATER THAN NORMAL
AND THE LATEST DATE OF THE FIRST FALL FREEZE ON RECORD. THE
FOLLOWING TABLE LISTS THE LATEST DATES OF THE FIRST FALL FREEZE AT
AUGUSTA.

ANOTHER COLD FRONT BROUGHT EVEN MORE COLD AIR STRAIGHT OUT OF THE
ARCTIC A FEW DAYS LATER, WITH AUGUSTA DROPPING ALL THE WAY DOWN TO
20 DEGREES ON NOVEMBER 10 AND 11. ALTHOUGH THE EXTREME COLD
GRADUALLY LESSENED, A SERIES OF COLD FRONTS KEPT BRINGING MORE COLD
AIR INTO THE AREA. THERE WAS A BRIEF BREAK IN EARLY DECEMBER WHEN
AUGUSTA SAW 50 DEGREES FOR TWO STRAIGHT DAYS. A STORM SYSTEM ON
DECEMBER 12 BROUGHT SNOW CHANGED TO FREEZING RAIN, WITH COLD AIR
POURING IN BEHIND THE STORM. THE TEMPERATURE DID NOT RISE ABOVE
FREEZING AGAIN FOR 7 STRAIGHT DAYS. MORE SNOW AND FREEZING RAIN CAME
ON DECEMBER 22 AND 23, WITH EVEN MORE SNOW ON CHRISTMAS MORNING.
VERY COLD AIR AGAIN POURED IN BEHIND THE CHRISTMAS DAY SNOWSTORM,
WITH THE TEMPERATURE NOT RISING ABOVE FREEZING FOR THE REST OF THE
YEAR. IN FACT, THE LAST 5 DAYS OF 2017 DID NOT WARM ABOVE 11
DEGREES, WITH EACH NIGHT FALLING WELL BELOW ZERO. THE TEMPERATURE OF
15 BELOW ZERO ON DECEMBER 29 WAS THE COLDEST TEMPERATURE EVER
RECORDED IN THE MONTH OF DECEMBER. THE TABLE BELOW LISTS THE COLDEST
TEMPERATURES OBSERVED IN DECEMBER AT AUGUSTA.

DEGREES ABOVE NORMAL. THE WARMEST YEAR ON RECORD WAS 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

REPORTED. THE WETTEST WAS IN 2005 WHEN 57.31 INCHES FELL. THE
