THE SNOWY PATTERN THAT DEVELOPED TOWARDS THE END OF WINTER CONTINUED
INTO THE THE FIRST WEEK OF SPRING IN THE AUGUSTA AREA. AS ONE SYSTEM
EXITED ON MARCH 1ST, ANOTHER SYSTEM CROSSED ON MARCH 2ND BRINGING
LIGHT SNOW. A MORE SIGNIFICANT LOW PRESSURE SYSTEM TRACKED ALONG THE
SOUTHERN NEW ENGLAND COASTLINE MARCH 4TH, WHICH BROUGHT MORE
SUBSTANTIAL SNOW TO THE REGION. QUIET WEATHER FOLLOWED UNTIL A
STRONG LOW PRESSURE SYSTEM IMPACTED NEW ENGLAND MARCH 13TH INTO THE
MORNING OF MARCH 15TH. THIS SYSTEM BROUGHT SIGNIFICANT SNOWFALL TO
INTERIOR NEW ENGLAND. RELATIVELY QUIET WEATHER FOLLOWED WITH A
GRADUAL MELTING OF THE SNOWPACK. RELATIVELY QUIET WEATHER CONTINUED
THROUGH THE FIRST HALF OF APRIL WITH A BRIEF WARM SPELL AROUND THE
MIDDLE OF THE MONTH. THE AUGUSTA AREA ECLIPSED THE 70 DEGREE MARK
FOR THE FIRST TIME OF THE SEASON ON THE 13TH WHEN THE HIGH
TEMPERATURE REACHED 76 DEGREES. THEREAFTER, THE NAO TOOK A DIVE INTO
NEGATIVE TERRITORY AS STRONG AND PERSISTENT OMEGA BLOCK FORMED OVER
EASTERN NORTH AMERICA AND THE NORTH ATLANTIC. THIS BLOCKING PATTERN
PERSISTED INTO THE FIRST WEEK OF MAY THAT LEAD TO MULTIPLE RAIN
EVENTS, TEMPERATURES RUNNING BELOW NORMAL, AND WHEN IT WASN`T
RAINING IT WAS OFTEN CLOUDY WITH FREQUENT DRIZZLE. THERE WERE ALSO
DAYS WITH VERY LITTLE VARIATION BETWEEN THE HIGH AND LOW
TEMPERATURE. ALSO DURING THIS PATTERN A SIGNIFICANT RAIN EVENT
OCCURRED ON APRIL 30TH INTO MAY 1ST WHEN A STORM TOTAL OF 4.69
INCHES OF RAIN FELL IN AUGUSTA. ACROSS AREAS NORTH AND EAST OF
AUGUSTA 5 TO 6 INCHES OF RAIN FELL RESULTING IN SIGNIFICANT
FLOODING. THE OMEGA BLOCK THAT PLAGUED THE NORTHEAST FOR THE BETTER
PART OF THREE WEEKS BROKE DOWN BY MAY 6TH. DRY WEATHER FOLLOWED
THROUGH THE MIDDLE OF THE MONTH AND WITH THE EXCEPTION OF A FEW COOL
DAYS AND SEASONABLY COLD NIGHTS, TEMPERATURES TRENDED ABOVE NORMAL.
ONE OF THESE COLD NIGHTS OCCURRED ON MAY 17TH INTO THE MORNING OF
THE 18TH WHEN THE TEMPERATURE FELL TO 36 DEGREES WITH WIDESPREAD
FREEZING TEMPERATURES ACROSS CENTRAL MAINE. ANOTHER HEAVY RAIN EVENT
OCCURRED MAY 20TH INTO THE 21ST WHEN A STORM TOTAL OF 2.02 INCHES OF
RAIN FELL. A RIDGE OF HIGH PRESSURE THEN DOMINATED THE WEATHER
PATTERN THE LAST WEEK OF MAY RESULTED IN FAIR WEATHER WITH SOME VERY
WARM DAYS INTERMIXED WITH COOLER DAYS THANKS TO AFTERNOON SEA
BREEZES.

THE AVERAGE TEMPERATURE FOR THE SPRING SEASON WAS 46.6 DEGREES,
WHICH WAS 2.9 DEGREES ABOVE NORMAL AND THE 6TH WARMEST SPRING ON
RECORD. THE WARMEST SPRING ON RECORD WAS 49.0 DEGREES IN 2010. THE
COOLEST WAS 37.9 DEGREES IN 1956. THE FOLLOWING TABLE LISTS THE
