MUCH WARMER THAN NORMAL. THIS PERIOD OF MILD WEATHER PEAKED ON
JANUARY 16 WHEN THE TEMPERATURE REACHED 50 DEGREES AND MORE THAN 1
INCH OF RAIN FELL. SOME COOLER WEATHER RETURNED BEHIND THIS STORM.
THE NEXT BIG STORM WAS ON FEBRUARY 1 AN 2 WHEN 7.9 INCHES OF SNOW
AND SLEET FELL. A VERY COLD ARCTIC AIR MASS SPILLED INTO THE
CENTRAL UNITED STATES IN EARLY FEBRUARY, AND NEW ENGLAND FOUND
ITSELF ON THE EASTERN EDGE OF THIS AIR MASS. THIS BROUGHT
CONSISTENTLY COLD WEATHER AND A FEW WINTER STORMS, BUT SPARED THE
REGION THE MORE BRUTAL COLD OBSERVED TO THE WEST. THE TEMPERATURE
STAYED BELOW FREEZING FOR THE BETTER PART OF TWO WEEKS IN MID
FEBRUARY. THE COLDEST TEMPERATURE WAS 4 ABOVE ZERO ON FEBRUARY 10.

HISTORICAL RECORDS AT MANCHESTER BEGAN IN 1885, BUT WITHIN THIS

THIS, HISTORICAL RECORDS SHOULD BE CONSIDERED INCOMPLETE AS SOME
SIGNIFICANT EXTREMES MAY BE MISSING FROM THE DATA. MORE CONSISTENT
MODERN RECORDS BEGAN IN 1998 AND CONTINUE TO THE PRESENT.
