UNLESS NOTED...ALL STATISTICS ARE FOR THE OFFICIAL CLIMATE STATION

...WARMEST YEAR EVER FOR LAS VEGAS...

AT THE OFFICIAL CLIMATE STATION FOR LAS VEGAS AT MCCARRAN
INTERNATIONAL AIRPORT THE AVERAGE TEMPERATURE FOR 2014 WAS 72.0
DEGREES. THIS SMASHED THE PREVIOUS RECORD OF 71.2 SET BACK IN 2012.
THE NORMAL AVERAGE HIGH FOR LAS VEGAS IS 69.4 DEGREES.

THE WARM YEAR WAS A COMBINATION OF THE VERY WARM HIGH TEMPERATURES
AND LOW TEMPERATURES, ESPECIALLY DURING THE WINTER AND FALL MONTHS
OF THE YEAR. THE AVERAGE HIGH TEMPERATURE WAS 82.6 DEGREES, WHICH
RANKS AS THE 4TH WARMEST EVER ON RECORD. THE NORMAL AVERAGE HIGH IS
80.1 DEGREES AND THE WARMEST EVER WAS 83.0 SET IN 1940 AND TIED IN
1947. THE AVERAGE LOW WAS 61.3 WHICH RANKS AS THE WARMEST EVER. THE
PREVIOUS RECORD WAS 60.5 SET IN 2012 AND THE NORMAL IS 58.7 DEGREES.

THERE WERE ONLY 2 DAYS ALL YEAR WITH A LOW TEMPERATURE OF 32 DEGREES
OR BELOW. THIS TIES THE PREVIOUS RECORD OF 2 SET IN 2005. THE NORMAL
SUCH NUMBER OF DAYS IS 8. MORE IMPRESSIVELY, THERE WERE ONLY 15 DAYS
ALL YEAR WHERE THE TEMPERATURE FELL BELOW 40 DEGREES FOR A LOW. THIS
SMOKED THE OLD RECORD OF 28 SET IN 2010. THE NORMAL NUMBER OF DAYS
WITH A LOW BELOW 40 DEGREES IS 58 BASED ON THE PERIOD OF 1981
THROUGH 2010.

THE HIGHEST TEMPERATURE ALL YEAR WAS 112 DEGREES RECORDED ON JULY
1ST, JULY 13TH AND JULY 23RD. THE LOWEST TEMPERATURE RECORDED ALL
YEAR WAS 30 DEGREES ON DECEMBER 29TH. THE HIGHEST MINIMUM
TEMPERATURE RECORDED IN ALL OF 2014 WAS 90 DEGREES ON JULY 25TH. THE
COLDEST HIGH TEMPERATURE OF THE ENTIRE YEAR WAS ON NEW YEAR`S EVE
DAY (DECEMBER 31ST) WHEN THE HIGH REACHED ONLY 43 DEGREES.

THERE WAS A TOTAL OF 80 DAYS IN 2014 WHERE THE HIGH TEMPERATURE
REACHED 100 DEGREES OR GREATER. THE NORMAL NUMBER OF SUCH DAYS IS
70. THERE WERE SIX DAYS WHERE THE HIGH REACHED 110 DEGREES OR
GREATER WHICH IS 2 DAYS BELOW NORMAL. ONLY 4 DAYS HAD A HIGH
TEMPERATURE BELOW 50 DEGREES WHICH IS THE LOWEST TOTAL FOR A YEAR
SINCE 2005 WHEN THERE WERE 3 SUCH DAYS. THE RECORD FOR THE LEAST
NUMBER OF DAYS IN A YEAR WITH A HIGH BELOW 50 DEGREES IS ZERO SET IN
2000. A TOTAL OF 53 DAYS HAD LOW TEMPERATURES OF 80 DEGREES OR
GREATER. THE NORMAL NUMBER OF SUCH DAYS IS 33.

THE TOTAL PRECIPITATION WAS 1.81 INCH, WHICH RANKED AS THE 10TH
DRIEST EVER. THE NORMAL PRECIPITATION IS 4.19 INCHES. THE DRIEST
EVER WAS 0.56 INCH SET IN 1953.

PRECIPITATION TOTALS WERE GREATEST ON THE WEST SIDE OF THE VALLEY,
ESPECIALLY IN THE SOUTHWEST DUE TO SEVERAL LOCALLY HEAVY
RAIN-PRODUCING THUNDERSTORMS DURING THE 2014 NORTH AMERICAN MONSOON
SEASON. RAINFALL TOTALS IN MANY PLACES HERE EXCEEDED 4 INCHES. BY
CONTRAST, CENTRAL AND THE SOUTHEASTERN PARTS OF THE VALLEY WERE THE
DRIEST AND MOST OF THIS AREA SAW UNDER 2 INCHES OF PRECIPITATION FOR
THE YEAR.
