THE YEAR BEGAN WITH A RELATIVELY MILD WINTER WITH ONLY BRIEF PERIODS
OF COLDER WEATHER. THE TEMPERATURE WARMED INTO THE 50S ON JANUARY 11
AND 12. THE MOST CONSISTENT PERIOD OF COLD WEATHER WAS ABOUT A WEEK
LATER WHEN AUGUSTA STAYED BELOW FREEZING FOR 5 STRAIGHT DAYS AND SAW
A LOW OF 3 BELOW ZERO ON JANUARY 18. BUT MILD WEATHER KEPT
RETURNING. THERE WERE A FEW MORE BRIEF BOUTS OF ARCTIC AIR IN
FEBRUARY INCLUDING 4 MORE SUBZERO LOWS, THE COLDEST BEING 9 BELOW ON
FEBRUARY 15. BUT OVERALL THE WINTER PERIOD WAS QUITE MILD. BY LATE
FEBRUARY AND EARLY MARCH THERE WERE EVEN A FEW MORE 50 DEGREE DAYS,
WITH THE WARMEST REACHING 61 ON MARCH 9. MORE FREQUENT STORMY
WEATHER WAS OBSERVED IN THE FIRST PART OF THE SPRING. A NEW STORM
SYSTEM WOULD BRING RAIN OR WINTRY WEATHER JUST ABOUT EVERY WEEK.
MORE THAN AN INCH OF RAIN FELL ON APRIL 2 AND 3. A WEEK LATER SAW
ANOTHER INCH OF PRECIPITATION ON APRIL 9 AND 10, THIS TIME WITH RAIN
CHANGING TO SNOW AS THE TEMPERATURE COOLED. A FEW DAYS LATER SAW
NEARLY 2 INCHES OF RAIN ON APRIL 13. AFTER THIS STORM MOVED BY, THE
WEATHER TURNED COOLER WITH BELOW NORMAL TEMPERATURES QUITE COMMON
FROM THE LAST HALF OF APRIL INTO THE FIRST HALF OF MAY ALONG WITH
FREQUENT PRECIPITATION INCLUDING A VERY LATE SNOWFALL ON MAY 9. THIS
WAS ALSO THE LAST FREEZE OF THE SPRING.
SUDDENLY IN MID MAY THE FREQUENT STORMY WEATHER ENDED AND
PRECIPITATION LARGELY STOPPED. THE PERSISTENT TROUGH WHICH BROUGHT
THE COOL AND STORMY WEATHER SHIFTED TO THE EAST. INSTEAD, FREQUENT
COOL, DRY AIR MASSES SPILLED DOWN OUT OF CANADA. THE LAST
SIGNIFICANT RAINFALL WAS ON MAY 15 WHEN MORE THAN HALF AN INCH OF
RAIN FELL. BARELY ANY RAIN FELL AGAIN FOR MORE THAN A MONTH CAUSING
DROUGHT CONDITIONS TO DEVELOP RAPIDLY. THE TEMPERATURE DURING THIS
TIME WAS FREQUENTLY WARM DURING THE DAY AND COOL AT NIGHT DUE TO THE
DRY AIR MASSES WHICH DOMINATED THE PERIOD. ALTHOUGH THERE WERE SOME
DAYS OF 80 DEGREE WARMTH IN LATE MAY, THE TEMPERATURE DROPPED INTO
THE 30S ON JUNE 1. THE FIRST STRETCH OF CONSISTENTLY HOT WEATHER
CAME IN MID JUNE WHEN AUGUSTA SAW 3 STRAIGHT DAYS ABOVE 90 DEGREES
FROM JUNE 18 THROUGH 20. THE HOTTEST TEMPERATURE OF THE YEAR WAS 94
ON JUNE 20. JUST AS THE HEAT AND HUMIDITY BEGAN TO CLIMB TOWARD THE
END OF JUNE, FINALLY SOME DROUGHT RELIEF ARRIVED. FROM JUNE 28
THROUGH 30 NEARLY 2 INCHES OF RAIN FELL AS A SLOW MOVING LOW
PRESSURE SYSTEM BROUGHT FREQUENT SHOWERS AND THUNDERSTORMS. UNTIL
THIS RAINFALL, AUGUSTA WAS ENDURING ITS DRIEST PERIOD ON RECORD FOR
THIS TIME OF YEAR. SUCH CONSISTENTLY DRY WEATHER WAS UNPRECEDENTED
FOR THE SPRING WHICH IS TYPICALLY THE RAINIEST TIME OF YEAR. THE
TABLE BELOW LISTS THE LEAST PRECIPITATION OBSERVED DURING THIS
STRETCH OF TIME.

ALTHOUGH THE DROUGHT BUSTING RAINS ENDED, MORE FREQUENT SHOWERS AND
THUNDERSTORMS IN JULY KEPT THE DROUGHT FROM WORSENING, AT LEAST FOR
THE FIRST HALF OF THE MONTH. LATER IN JULY THE HEAT AND HUMIDITY
BEGAN TO BUILD AGAIN WITH MANY DAYS IN THE MID TO UPPER 80S AND
NIGHTTIME LOWS IN THE MID 60S TO LOW 70S. THIS CONTINUED THROUGH MID
AUGUST WITH ONE EXCEPTION. TROPICAL STORM ISAIAS MOVED THROUGH THE
REGION ON AUGUST 4 BRINGING ABOUT HALF AN INCH OF RAIN AND 45 MPH
WIND GUSTS. THE FIRST STRONG COLD FRONT CAME THROUGH ON AUGUST 15,
BRINGING THE HEAT AND HUMIDITY TO AN END. ALTHOUGH THERE WERE A FEW
MORE HOT DAYS IN LATE SUMMER AND EARLY FALL, THE PERSISTENT HEAT WAS
OVER. THIS WAS THE 6TH WARMEST SUMMER ON RECORD AT AUGUSTA.
MORE THAN AN INCH OF RAIN FELL ON AUGUST 29, BUT THIS WOULD BE THE
LAST SIGNIFICANT RAINFALL FOR A WHILE AS DROUGHT CONDITIONS EMERGED
AGAIN IN SEPTEMBER. BARELY ANY RAIN FELL DURING THE NEXT 4 WEEKS AS
A SERIES OF COLD FRONTS BROUGHT DRY, CONTINENTAL AIR MASSES INTO THE
REGION. THIS OFTEN BROUGHT WARM DAYS AND OCCASIONALLY COOL NIGHTS.
THE COOLEST TEMPERATURES WERE IN MID SEPTEMBER WHEN AUGUSTA SAW A
FEW FROSTY NIGHTS IN THE MID 30S. FINALLY AFTER A MONTH OF DRY
WEATHER A STORM SYSTEM ON SEPTEMBER 30 BROUGHT NEARLY AN INCH OF
RAIN ALONG WITH 49 MPH WINDS. THIS BEGAN A GRADUAL SHIFT IN THE
WEATHER PATTERN WITH MORE FREQUENT STORMINESS RETURNING. FREQUENT
FRONTAL SYSTEMS BROUGHT A TOPSY TURVY TEMPERATURE PATTERN WITH
OCCASIONAL WARMTH REPLACED BY COLD. THE FIRST FREEZE WAS ON OCTOBER
12. THE FIRST OF THE SIGNIFICANT STORM SYSTEMS BROUGHT MORE THAN 2
INCHES OF RAIN ON OCTOBER 13. A FEW DAYS LATER ANOTHER 2 INCHES WAS
RECORDED ON OCTOBER 16 AND 17. LATER IN OCTOBER THE TEMPERATURE
TURNED COLDER WITH SNOW OBSERVED JUST BEFORE HALLOWEEN. WHILE THE
COLDER WEATHER LASTED A FEW WEEKS, ANOTHER SHIFT WAS IN STORE FOR
NOVEMBER. AUGUSTA SAW ONE OF THE MOST INTENSE AND LONG LASTING LATE
SEASON WARM SPELLS ON RECORD. BEGINNING ON NOVEMBER 5, AUGUSTA SAW 8
STRAIGHT DAYS WARM INTO THE 60S OR HIGHER INCLUDING 7 CONSECUTIVE
DAILY RECORD HIGHS. THE WARMEST WAS 73 ON NOVEMBER 7.
A COLD FRONT ON NOVEMBER 12 BROUGHT THE UNUSUAL WARMTH TO AN END
WITH A COOLER AND STORMIER PATTERN RETURNING. A STRONG STORM SYSTEM
BROUGHT SOME RAIN AND WIND ON NOVEMBER 15 AND 16 WITH GUSTS TO 56
MPH BRINGING DOWN TREES AND POWER LINES IN THE AREA. THE NEXT STORM
ON NOVEMBER 23 BROUGHT MORE THAN 2 INCHES OF RAIN. ANOTHER STRONG
STORM ON NOVEMBER 30 INTO DECEMBER 1 BROUGHT MORE THAN 3 INCHES OF
RAIN AND 55 MPH WINDS, AGAIN CAUSING DAMAGE IN THE AREA. JUST A FEW
DAYS LATER ANOTHER COLDER STORM BROUGHT A HEAVY WET SNOWFALL WHICH
ALSO CAUSED DAMAGE TO TREES AND POWER LINES. MORE THAN 2 INCHES OF
LIQUID EQUIVALENT PRECIPITATION WAS RECORDED FROM THIS SNOW ON
DECEMBER 5. THE COLDEST AIR OF THE NEW WINTER SEASON CAME IN MID
DECEMBER WITH AUGUSTA STAYING BELOW FREEZING FOR 7 STRAIGHT DAYS
ALONG WITH SOME MORE SNOW. HOWEVER, A WARM UP BEGAN BEFORE
CHRISTMAS. BY CHRISTMAS DAY ANOTHER WARM RAIN STORM HAD ARRIVED. IT
WAS THE WARMEST AND WETTEST CHRISTMAS ON RECORD AT AUGUSTA WITH THE
TEMPERATURE REACHING 60 DEGREES, MORE THAN 2 INCHES OF RAIN FALLING,
AND WINDS GUSTING TO 48 MPH. ALTHOUGH THE TEMPERATURE COOLED BEHIND
THIS STORM, IT REMAINED MILD THROUGH THE END OF THE YEAR.
THE AVERAGE TEMPERATURE FOR THE YEAR WAS 47.7 DEGREES WHICH WAS 2.0
DEGREES ABOVE NORMAL AND THE 5TH WARMEST YEAR ON RECORD. THE WARMEST
YEAR WAS IN 1999 WHEN THE AVERAGE TEMPERATURE AS 49.3 DEGREES. THE
COLDEST WAS 42.8 DEGREES IN 1968. THE FOLLOWING TABLE LISTS THE
