...JUNE MELTED AWAY MANY RECORDS...

JUNE 2013 WILL GO DOWN AS ONE OF - IF NOT THE HOTTEST - JUNES ON 
RECORD IN THE MOJAVE DESERT AND SOUTHERN GREAT BASIN AS WELL AS THE 
DRIEST IN MOST LOCATIONS. THE HIGHEST TEMPERATURES OF THE MONTH WERE 
ALL RECORDED FROM THE 28TH THROUGH THE 30TH WITH THE OVERWHELMING 
MAJORITY OF STATIONS REACHING THEIR HIGHEST TEMPERATURES ON THE 
30TH. BY CONTRAST THE LOWEST READINGS OF THE MONTH WERE SET FROM 
EITHER THE 1ST THROUGH THE 4TH OR FROM THE 13TH THROUGH THE 17TH. 

THE FIRST TWO-THIRDS OF THE MONTH HIGH PRESSURE ALOFT LARGELY 
DOMINATED RESULTING IN WARMER THAN NORMAL AND DRY CONDITIONS. TWO 
SYSTEMS, ONE THAT PASSES ACROSS NORTHERN NEVADA ON THE 4TH AND 
ANOTHER THAT MOVED FROM CENTRAL CALIFORNIA TOWARD NORTHEAST NEVADA 
ON THE 10TH, BROUGHT SHOWERS AND THUNDERSTORMS THAT PRODUCED MAINLY 
LIGHT PRECIPITATION TO PORTIONS OF NORTHERN INYO AND ESMERALDA 
COUNTIES. 

A STRONG AREA OF LOW PRESSURE THAT MOVED ACROSS PACIFIC NORTHWEST 
FROM THE 17TH THROUGH THE 20TH BROUGHT A SUBSTANTIAL COOLING TREND 
FOR MOST OF THE LATER THIRD OF THE MONTH. HOWEVER, THE PATTERN 
CHANGED DRASTICALLY BY THE 27TH AS A STRONG AREA OF HIGH PRESSURE 
BUILT OVER THE FOUR CORNERS REGION. THIS HIGH RESULTED IN A 
SIGNIFICANT WARMING TREND AS IT MIGRATED FURTHER WEST AS WELL AS 
HELPED TO PUSH MONSOONAL MOISTURE INTO THE MOJAVE DESERT AND 
SOUTHERN GREAT BASIN. THIS RESULTED IN ISOLATED SHOWERS AND 
THUNDERSTORMS ESPECIALLY ACROSS MOHAVE, LINCOLN, ESMERALDA AND 
CENTRAL NYE COUNTIES AND THE HIGHER ELEVATIONS OF CLARK AND INYO 
COUNTIES MAINLY DURING THE AFTERNOON AND EVENING HOURS.

THE OUTSTANDING EVENT OF THE MONTH WAS THE HEAT WAVE THAT DEVELOPED 
IN THE CLOSING DAYS OF THE MONTH. THIS RESULTED IN NUMEROUS LOCATION 
BREAKING OR TYING DAILY RECORD HIGH MAXIMUM TEMPERATURES, RECORD 
HIGH MINIMUM TEMPERATURES, REACHING OR TYING ALL-TIME JUNE OR 
ALL-TIME STATION HIGH TEMPERATURES AND SETTING OR TYING RECORDS FOR 
THE GREATEST NUMBER OF CONSECUTIVE DAYS WITH THE TEMPERATURE AT OR 
ABOVE A SPECIFIC THRESHOLD.
