OCTOBER BEGAN WITH A FEW DAYS OF COOL, FALL-LIKE WEATHER, BUT IT DID
NOT LAST LONG. A RIDGE OF HIGH PRESSURE BUILT OVER THE WESTERN
ATLANTIC AND A PERSISTENT TROUGH DEVELOPED OVER THE CENTER OF THE
UNITED STATES. THIS BROUGHT A PROLONGED PERIOD OF SOUTH TO
SOUTHWESTERLY FLOW WHICH TRANSPORTED WARM, OFTEN HUMID AIR INTO NEW
ENGLAND FOR MOST OF THE MONTH. ALTHOUGH A FEW COLD FRONTS MANAGED TO
SNEAK IN AND BRING BRIEFLY COOLER WEATHER, THE WARM WEATHER KEPT
RETURNING. BY THE END OF THE MONTH THE PATTERN BEGAN TO SHIFT AGAIN,
WITH TWO LARGE STORM SYSTEMS BRINGING HEAVY RAINFALL DURING THE
FINAL WEEK. THE FIRST STORM BROUGHT MORE THAN 3 INCHES OF RAIN FROM
THE 24TH THRU 26TH. THE SECOND BROUGHT ALMOST 2 MORE INCHES OF RAIN
ON THE 29TH AND 30TH BUT WAS ACCOMPANIED BY HIGH WIND AS WELL. WIND
GUSTS WERE OBSERVED UP TO 59 MPH AT THE NWS OFFICE IN GRAY ON THE
MORNING OF THE 30TH. THESE STRONG WINDS CAUSED WIND DAMAGE IN THE
AREA, LEAVING MANY WITHOUT POWER JUST IN TIME FOR HALLOWEEN.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 57.0 DEGREES WHICH WAS 7.9
DEGREES ABOVE NORMAL AND THE WARMEST OCTOBER ON RECORD. UNTIL THIS
YEAR, THE WARMEST OCTOBER WAS IN 2007 WHEN THE AVERAGE TEMPERATURE
WAS 53.9 DEGREES. THE COOLEST WAS IN 2009 WHEN IT WAS ONLY 46.2
DEGREES. THE FOLLOWING TABLE LISTS THE WARMEST OCTOBERS AT GRAY.

WARMEST AVERAGE TEMPERATURE IN OCTOBER (SINCE 1995)...
RANK  TEMP  YEAR
1     57.0  2017 <===
2     53.9  2007
3     53.0  1995
4     52.2  2014
5     52.0  2012

A TOTAL OF 5.66 INCHES OF RAIN FELL WHICH WAS 0.52 INCHES ABOVE
NORMAL. MOST OF THIS RAIN FELL IN THE FINAL WEEK OF THE MONTH WHEN
4.92 INCHES WAS MEASURED. THE WETTEST OCTOBER ON RECORD WAS IN 2005
WHEN 16.33 INCHES WAS MEASURED. THE DRIEST WAS IN 1997 WHEN ONLY
1.29 INCHES WAS MEASURED.

NO SNOW FELL WHICH IS ONLY 0.1 INCHES BELOW NORMAL. IN THE SHORT 23-
YEAR HISTORY OF WEATHER OBSERVATIONS AT THE NATIONAL WEATHER SERVICE
OFFICE IN GRAY, THERE HAVE BEEN ONLY 2 YEARS WHICH SAW MEASURABLE
SNOWFALL, MOST RECENTLY IN 2011. THERE HAVE BEEN AN ADDITIONAL 12
YEARS WHICH RECORDED A TRACE OF SNOWFALL, MOST RECENTLY IN 2016.
