2018 STARTED OFF ON A ROLLER COASTER RIDE IN THE TEMPERATURE
DEPARTMENT, THEN AN UNPRECEDENTED STRING OF COLD DAYS OCCURRED FROM
FEBRUARY 15TH UNTIL APRIL 14TH, WHERE DAILY HIGHS NEVER REACHED
ABOVE NORMAL (58 DAYS). THIS STRING OF COLD WEATHER WAS PUNCTUATED
BY A RECORD LOW TEMPERATURE OF JUST 4 DEGREES SET ON APRIL 6TH.

TEMPERATURES THEN FOLLOWED CLOSER TO NORMAL, BUT MORE RECORDS WERE
SET IN AUGUST. THREE DAYS SET RECORD HIGHS WITH A 101 ON THE 9TH OF
AUGUST, AND A 107 ON THE 10TH AND 11TH.

FOR MONTHLY AVERAGES, FEBRUARY WAS THE COLDEST WITH RESPECT TO
NORMAL, AVERAGING 18.2 DEGREES BELOW NORMAL. MAY WAS THE WARMEST
WITH RESPECT TO NORMAL, COMING IN AT 7.6 DEGREES ABOVE NORMAL.

PRECIPITATION FOR THE MOST PART WAS NEAR NORMAL, BUT A NOTICEABLE
DRY PERIOD OCCURRED FROM ABOUT JULY 11TH UNTIL AUGUST 26TH. ONLY
0.03 OF AN INCH FELL IN THAT PERIOD. NORMALLY, OVER 2 INCHES OF
RAINFALL WOULD OCCUR.
