AFTER A DRY SUMMER AND EARLY FALL, THE WEATHER PATTERN SHIFTED AS
OCTOBER BEGAN. WITH THE STORM TRACK CLOSER TO NEW ENGLAND, MORE
FREQUENT STORM SYSTEMS BROUGHT WELCOME RAINFALL AFTER A SUMMER OF
DROUGHT. A TOPSY TURVY TEMPERATURE TREND ALSO OCCURRED, WHICH IS
TYPICAL OF THE FREQUENT FRONTAL SYSTEMS THAT ACCOMPANY FALL IN NEW
ENGLAND. THE WARMEST TEMPERATURE WAS 76 DEGREES ON THE 10TH. THE
MOST SIGNIFICANT RAINFALL CAME IN THE MIDDLE OF THE MONTH. THE FIRST
BROUGHT NEARLY 2 INCHES OF RAIN ON THE 13TH. THE SECOND BROUGHT
NEARLY 2 MORE INCHES ON THE 16TH AND 17TH. CONDITIONS TURNED MORE
CONSISTENTLY COLD TOWARD THE END OF THE MONTH. THE FIRST SNOWFLAKES
OF THE SEASON WERE OBSERVED ON THE 28TH, WHICH WAS ALSO THE FIRST
FREEZE OF THE FALL. THE LOW TEMPERATURE OF 24 ON THE 31ST WAS THE
COLDEST TEMPERATURE YET RECORDED IN THE MONTH OF OCTOBER AT GRAY.
