...A VERY DRY...VERY WARM AND VERY WINDY JUNE FOR THE AREA...

JUNE 2014 WAS ATYPICAL IN MANY WAYS. THE MONTH, TYPICALLY ONE OF THE
DRIEST ACROSS THE AREA BASED ON CLIMATOLOGY, FINISHED WITH THE VAST
MAJORITY OF LOCATIONS SEEING NO PRECIPITATION AT ALL. DESPITE THE
PASSAGE OF SEVERAL STORM SYSTEMS, THE LACK OF MOISTURE ASSOCIATED
WITH THEM RESULTED IN SYSTEMS BEING EFFICIENT WIND PRODUCERS,
ESPECIALLY FOR THIS LATE IN THE SEASON, AND VERY LITTLE IN THE WAY
OF PRECIPITATION. ONLY TWO SYSTEMS DURING THE MONTH MANAGED TO
PRODUCE ANY PRECIPITATION. ON JUNE 10TH, ISOLATED SHOWERS AND
THUNDERSTORMS DEVELOPED ACROSS MAINLY THE HIGHER ELEVATIONS OF
NORTHERN INYO AND LINCOLN COUNTIES. IN LINCOLN COUNTY, LIGHTNING
FROM ONE STORM STARTED A NEARLY 150 ACRE BRUSH FIRE. FROM JUNE 26TH
THROUGH JUNE 27TH, ISOLATED SHOWERS AGAIN WET PORTIONS OF NORTHERN
INYO AND LINCOLN COUNTIES. HOWEVER, ANY PRECIPITATION THAT FELL WAS
VERY LIGHT.

GUSTY WINDS OVER 40 MPH WERE MORE COMMON IN JUNE THAN IS TYPICAL, AS
A HIGHER THAN NORMAL NUMBER OF COLD FRONTS PUSHED THROUGH THE AREA,
ESPECIALLY DURING THE MIDDLE TO LATER PART OF THE MONTH. GUSTY WINDS
TOOK PLACE ON JUNE 2ND, 10TH, 13TH THROUGH 17TH AND 24TH THROUGH
27TH. AT BARSTOW-DAGGETT, CALIFORNIA THERE WERE 11 DAYS WITH GUSTS
OF 40 MPH OR GREATER WHICH WAS THE HIGHEST JUNE TOTAL IN THE LAST 10
YEARS. ON JUNE 16TH, THE WIND WAS STRONG ENOUGH TO KNOCK DOWN A
LARGE TREE ON MT CHARLESTON, NEVADA IN KYLE CANYON.

WITH SO MANY COLD FRONTS PRESSING THROUGH, SEVERAL SIGNIFICANT
BREAKS IN THE HEAT TOOK PLACE. THE COOLEST READINGS OF THE MONTH
WERE SET FROM THE 2ND THROUGH THE 4TH OR FROM THE 15TH THROUGH 19TH.
BY CONTRAST, THE HOTTEST WEATHER OF THE MONTH ARRIVED IN THE CLOSING
DAYS AS A STRONG AREA OF HIGH PRESSURE ALOFT FINALLY BUILT INTO THE
SOUTHWESTERN UNITED STATES. MOST AREAS SAW THEIR HOTTEST TEMPERATURE
OF JUNE ON THE 30TH WITH THE EXCEPTION OF THE COLORADO RIVER VALLEY
WHERE THE HIGHEST READINGS WERE BASICALLY REACHED ON THE 9TH.
