REMARKS...

2015 WAS A VERY WET YEAR...PLACING AS THE THIRD WETTEST YEAR ON
RECORD. IT WAS 1.25 INCHES SHORT OF THE SECOND WETTEST YEAR OF
1967...BUT WELL SHORT OF THE 1973 RECORD OF 60.88 INCHES. MUCH OF
THE ABOVE NORMAL PRECIPITATION CAME IN THE LAST HALF OF THE
YEAR...WITH MONTHLY TOTALS OF FOUR OF THE LAST SIX MONTHS OF THE
YEAR PLACING IN THE TOP ELEVEN OF THE HIGHEST TOTALS FOR THEIR
RESPECTIVE MONTHS. 2015 ALSO RANKS AS THE FOURTEENTH HOTTEST YEAR ON
RECORD...WITH AVERAGES OF FIVE OF THE YEARS MONTHS PLACING IN THE
TOP TWENTY FOR THEIR RESPECTIVE MONTHS.

OF COURSE COLD TEMPERATURES STARTED THE YEAR...INCLUDING A SEVEN DAY
STRETCH IN JANUARY WHEN LOW TEMPERATURES WERE IN THE SINGLE DIGITS
ON SIX OF THE SEVEN DAYS. EXTREMELY HIGH PRESSURE AT THE SURFACE
ACCOMPANIED THIS VERY COLD ARIMASS...INCLUDING A RECORD HIGH READING
OF 1054.3 MILLIBARS ON JANUARY 7. A MUCH DIFFERENT SCENARIO BROUGHT
THE TEMPERATURE TO 78 DEGREES JUST THREE WEEKS LATER. THIS
TEMPERATURE WAS THE HIGHEST FOR ANY JANUARY DATE ON RECORD FOR
TOPEKA. THE 9.43 INCHES OF RAIN IN MAY WAS THE 29TH WETTEST FOR ANY
MONTH ON RECORD AND THE WETTEST MONTH IN TOPEKA SINCE JUNE 2010.
LATE JULY BROUGHT PERSISTENT HEAT WITH AN AVERAGE PEAK HEAT INDEX OF
104 FROM JULY 12 THROUGH JULY 28...AND HEAT INDEX VALUES NEARING 120
ON JULY 13 AND 24. AUGUST BROUGHT RELATIVELY COOL TEMPERATURES. THE
HIGHEST TEMPERATURE MEASURED THAT MONTH WAS 93 DEGREES. ONLY FOUR
OTHER MONTHS OF AUGUST ON RECORD HAD A LOWER HIGHEST TEMPERATURE.
FLASH FLOODING OCCURRED IN THE EVENING OF SEPTEMBER 10 AS 3.41
INCHES OF RAIN FELL IN AN HOUR...CAUSING SOME MOTORISTS TO BECOME
STRANDED IN THEIR VEHICLES AND REQUIRING WATER RESCUES. PERIODS OF
FREEZING RAIN AND SLEET FELL DURING THE LAST FEW DAYS OF NOVEMBER
AND LEAD TO SOME POWER OUTAGES AND MANY TRAFFIC ACCIDENTS. RAIN WAS
PERSISTENT IN THE DAYTIME HOURS OF DECEMBER 13 WITH A RECORD-
BREAKING 1.64 INCHES OF RAIN ACCUMULATING. THIS WAS THE SEVENTH
WETTEST DAY OF ANY DAY IN DECEMBER AND THIRTEENTH WETTEST OF ANY DAY
IN METEOROLOGICAL WINTER.
