...A WARM AND UNUSUALLY WET JUNE...

JUNE 2015 WILL GO DOWN AS ONE OF THE WARMEST JUNES ON RECORD ACROSS
THE MOJAVE DESERT AND SOUTHERN GREAT BASIN. IT WAS A MAJOR FLIP FROM
MAY WHICH BROKE THE STREAK OF ABOVE NORMAL MONTHS FOR TEMPERATURES
THAT WAS GOING IN LAS VEGAS SINCE SEPTEMBER 2014.

JUNE WAS A MONTH AT FIRST THAT DID NOT SEEM DESTINED FOR VICTORY AS
AN EXCEPTIONALLY WARM JUNE. ALTHOUGH THE MONTH OPENED WITH ABOVE
NORMAL TEMPERATURES, A TROUGH MOVED THROUGH THE REGION BETWEEN THE
3RD AND 6TH. THIS RESULTED LOCALLY GUSTY WINDS AND THE FIRST
PRECIPITATION OF THE MONTH WHICH TOOK PLACE ON THE 4TH, 5TH AND 6TH.
THIS PERIOD OF THE MONTH ALSO MARKED WHEN MOST LOCATIONS SET THEIR
COOLEST READINGS OF THE MONTH WHICH GENERALLY TOOK PLACE BETWEEN THE
2ND AND 6TH.

AFTER A BRIEF DRY PERIOD, PRECIPITATION RETURNED TO THE AREA
BEGINNING ON THE 9TH AS THE REMNANTS OF WHAT WAS PACIFIC HURRICANE
BLANCA MOVED ON INTO THE SOUTHWESTERN UNITED STATES TRIGGERING
SHOWERS AND THUNDERSTORMS. THIS MARKED THE FIRST TIME SINCE JUNE OF
1990 WHEN THE REMNANTS OF PACIFIC HURRICANE BORIS IMPACTED THE AREA
THAT THE REMNANTS OF A PACIFIC TROPICAL SYSTEM IMPACTED THE MOJAVE
DESERT AND SOUTHERN GREAT BASIN SO EARLY IN THE SEASON. SHOWERS AND
THUNDERSTORMS ASSOCIATED WITH THE REMNANTS OF BLANCA TOOK PLACE EACH
DAY BETWEEN THE 9TH AND 14TH. A DIGGING TROUGH INTERACTED WITH THE
REMNANT MOISTURE INITIALLY HELPING TO FUEL THE DEVELOPMENT OF
SHOWERS AND THUNDERSTORMS, HOWEVER, AS THIS TROUGH MOVED INLAND IT
EVENTUALLY SWEPT THE MOISTURE FROM BLANCA OUT OF THE AREA.

THERE WERE SEVERAL REPORTS OF FLASH FLOODING IN THIS TIME PERIOD IN
INYO, SAN BERNARDINO, ESMERALDA AND LINCOLN COUNTIES. ON JUNE 10TH
TWO PEOPLE WERE INJURED RIDING MOTORCYCLES NEAR KEELER, CALIFORNIA
WHEN A TRAFFIC COLLISION TOOK PLACE DUE TO FLOWING WATER.

BY THE 13TH, TEMPERATURES STARTED TO HEAT UP AND A EXTENDED PERIOD
OF VERY HOT AND DRY WEATHER LASTED THROUGH JUNE 27TH. MANY LOCATIONS
SET THEIR HIGHEST READINGS OF THE MONTH ON EITHER THE 20TH OR 27TH
WITH SEVERAL LOWER MOJAVE DESERT VALLEY LOCATIONS EXCEEDING THE 115
DEGREE MARK.

THE 2015 MONSOON SEASON BEGAN ON THE 28TH WHEN THE FIRST PUSH OF
MONSOON MOISTURE MOVED INTO THE AREA FROM THE SOUTH. THIS RESULTED
IN HIGHER HUMIDITY AND CLOUD COVER THAT FURTHER HELD UP OVERNIGHT
LOW TEMPERATURES. IN ADDITION, SHOWERS AND THUNDERSTORMS FELL ACROSS
PORTIONS OF THE AREA EACH DAY BETWEEN THE 28TH AND 30TH. ON THE
29TH, A THUNDERSTORM PRODUCED A 63 MPH WIND GUST NEAR MEADVIEW,
ARIZONA. THE FOLLOWING DAY, A THUNDERSTORM WASHED MUD AND ROCKS ONTO
DEATH VALLEY ROAD NEAR THE INTERSECTION OF STATE ROUTE 168 IN
CALIFORNIA.

* NOTABLE EVENTS DURING THE MONTH:

JUNE 2015 WILL GO DOWN AS THE HOTTEST JUNE EVER ON RECORD IN LAS
VEGAS. THE AVERAGE MONTHLY TEMPERATURE FOR JUNE 2015 WAS 91.9
DEGREES SCORING A COME FROM BEHIND WIN IN THE LAST TWO DAYS OF THE
MONTH OVER THE PREVIOUS RECORD HOLDER - JUNE 2013 - WHICH HAD AN
AVERAGE TEMPERATURE OF 91.5 DEGREES.

THE HOTTEST JUNE EVER WAS A COMBINATION OF THE CONSISTENT HOT
STRETCH DURING THE LAST TWO-THIRDS OF THE MONTH THAT RESULTED IN
ABOVE NORMAL HIGH TEMPERATURES AND WARM LOW TEMPERATURES. THE
AVERAGE HIGH TEMPERATURE THIS JUNE WAS 103.5 DEGREES WHICH RANKED AS
THE 5TH WARMEST EVER. THE WARMEST EVER FOR AVERAGE HIGH TEMPERATURE
WAS 105.0 SET IN 1940. THE AVERAGE LOW TEMPERATURE THIS JUNE WAS
80.2 DEGREES WHICH RANKS AS THE WARMEST EVER FOR JUNE. THE PREVIOUS
RECORD HOLDER WAS 79.1 SET IN 2013.

THERE WAS A RECORD-TYING NUMBER OF DAYS THIS JUNE WITH A HIGH
TEMPERATURE OF 105 DEGREES OR GREATER WITH 18 SUCH DAYS RECORDED.
THIS JUNE RECORD WAS FIRST SET IN JUNE 1974. THE NORMAL NUMBER IS 8
DAYS.

THIS JUNE`S MOST IMPRESSIVE RECORDS THOUGH CAME IN THE LOW
TEMPERATURE DEPARTMENT. THE HIGHEST MINIMUM TEMPERATURE EVER FOR
JUNE - 93 DEGREES - WAS LOGGED ON JUNE 30TH. THE PREVIOUS RECORD
PRIOR TO THIS JUNE WAS 89 DEGREES LAST SET ON JUNE 30, 2013. THERE
WERE A TOTAL OF 3 DAYS THIS JUNE IN WHICH THE LOW TEMPERATURE NEVER
FELL BELOW 90 DEGREES. PRIOR TO THIS JUNE LAS VEGAS NEVER OFFICIALLY
RECORDED A CALENDAR DAY LOW IN THE 90S.

THE LOW OF 93 ON JUNE 30TH AND THE HIGH OF 112 THAT DAY ALSO
RESULTED IN THE AVERAGE TEMPERATURE ONLY BEING 103 DEGREES. THIS
TIES THE WARMEST AVERAGE TEMPERATURE EVER FOR THE MONTH OF JUNE SET
ON JUNE 30, 2013.

THERE WERE ALSO A RECORD NUMBER OF DAYS WITH A LOW OF 80 DEGREES OR
GREATER. THERE WERE 17 SUCH DAYS WHICH BROKE THE PREVIOUS RECORD OF
13 DAYS SET IN 2006 AND TIED IN 2007 AND 2013.

THERE WERE 3 DAYS WITH A TRACE OR MORE OF PRECIPITATION AT MCCARRAN
WHICH MARKED THE FIRST TIME A JUNE HAD ANY PRECIPITATION SINCE 2010.
THE JUNE TOTAL OF 3 DAYS WITH A TRACE OR MORE WAS THE HIGHEST FOR A
JUNE SINCE 2009 WHEN THERE WERE 7 SUCH DAYS.

THUNDERSTORMS MOVED ACROSS THE LAS VEGAS VALLEY ON THE EVENING OF
THE 13TH AND PRODUCED A 55 MPH GUST AT MCCARRAN INTERNATIONAL
AIRPORT. THE FOLLOWING AFTERNOON, THUNDERSTORMS AGAIN FORMED IN THE
VALLEY AND IMPACTED THE EAST-CENTRAL PORTION. HEAVY RAIN CAUSED SOME
MINOR STREET FLOODING, KNOCKED OUT POWER TO 1724 NV ENERGY CUSTOMERS
AND TRIGGERED SLICK ROADS THAT RESULTED IN SEVERAL VEHICLE ACCIDENTS
INJURING 7 PEOPLE. SUSTAINED WINDS UP TO 41 MPH WERE REGISTERED AT
NELLIS AIR FORCE BASE. THE INSERT OF A SIGN ON A 7-ELEVEN STORE NEAR
NELLIS AND STEWART WAS BLOWN OUT AND LIGHTNING STRUCK A PALM TREE
AND SET IT ON FIRE.

A CONFIRMED TOTAL OF 17 PEOPLE WERE TREATED FOR HEAT-RELATED
INJURIES IN THE LAS VEGAS VALLEY DURING THE MONTH.
