..SUMMER WAS SLOW TO FADE TO FALL DURING OCTOBER 2014...

ALTHOUGH OCTOBER IS TYPICALLY THE HEART OF THE SECOND DRY SEASON OF
THE YEAR ACROSS THE MOJAVE DESERT AND SOUTHERN GREAT BASIN, A
SCARCITY OF STORMS EXISTED IN OCTOBER 2014 RESULTING IN A MONTH THAT
LACKED PRECIPITATION AND MUCH IN THE WAY OF STRONG WIND. MOST OF THE
MONTH FEATURED EITHER RIDGING ALOFT OVER OR JUST OFFSHORE OF THE
AREA OR A DRY WESTERLY FLOW ALOFT. THESE HELPED TO KEEP STORMS AWAY
FROM THE AREA EVEN IN A MONTH WHERE STORMS ARE TYPICALLY FEW IN
NUMBER AND OFTEN NOT TOO WET AS THE MAIN STORM TRACK TYPICALLY
REMAINS FURTHER NORTH.

A SYSTEM DIVING SOUTHEAST ACROSS THE ROCKIES BROUGHT VERY LIGHT
AMOUNTS OF PRECIPITATION TO THE AREA ON THE 2ND ALONG WITH A QUICK
SHOT OF COOLER AIR. HOWEVER, SUMMER QUICKLY MOVED BACK ON IN AS A
STRONG RIDGE ALOFT PUSHED INTO THE AREA BY THE 3RD. THE WARMEST
STRETCH OF THE MONTH WAS BETWEEN THE 4TH AND THE 7TH WHEN JUST ABOUT
ALL BUT A HANDFUL OF LOCATIONS LOGGED THEIR HIGHEST READINGS OF THE
MONTH. THIS WAS THE LAST TIME THE WARMEST LOWER MOJAVE DESERT
VALLEYS EITHER REACHED THE 90 DEGREE OR, IN A FEW CASES, TRIPLE
DIGIT MARK FOR THE YEAR.

THE FIRST NOTABLE STORM SYSTEM OF THE MONTH MOVED ACROSS THE AREA
FROM THE 8TH THROUGH THE 9TH AND BROUGHT PRECIPITATION MAINLY TO
PORTIONS OF MOHAVE AND SOUTHEASTERN SAN BERNARDINO COUNTIES.
RAINFALL AMOUNTS EXCEED A HALF AN INCH IN PORTIONS OF MOHAVE COUNTY,
ESPECIALLY IN THE KINGMAN AREA IN A TWO HOUR PERIOD ON THE EVENING
OF THE 8TH. SEVERAL STREETS IN KINGMAN HAD 4 OR MORE INCHES OF WATER
FLOW ACROSS THEM AS A RESULT OF THE QUICK BURST OF MODERATE TO HEAVY
RAIN.

ANOTHER STORM SYSTEM AFFECTED THE AREA FROM THE 17TH THROUGH THE
19TH AND DROPPED MAINLY VERY LIGHT AMOUNTS OF PRECIPITATION ACROSS
MOHAVE AND SOUTHEASTERN SAN BERNARDINO COUNTIES WITH MOST LOCATIONS
THAT RECEIVED PRECIPITATION REPORTING A TRACE OF RAIN.

THE STRONGEST COLD FRONT OF THE MONTH PUSHED ACROSS THE AREA ON THE
26TH ACCOMPANIED BY WIND GUSTS OF 30 TO 40 MPH AND HELPING TO USHER
IN THE COOLEST AIR OF THE MONTH. THE LOWEST READINGS OF THE MONTH
WERE ALL SET BETWEEN THE 27TH AND THE 31ST. THIS RESULTED IN THE
FIRST FREEZE OF THE SEASON FINALLY FOR MANY VALLEY LOCATIONS IN THE
SOUTHERN GREAT BASIN AND MID-ELEVATION AREAS OF THE MOJAVE DESERT
RANKING IT AS ONE OF THE LATEST ON RECORD.

THE FINAL STORM SYSTEM OF THE MONTH APPROACHED FROM CALIFORNIA ON
THE AFTERNOON AND EVENING HOURS OF HALLOWEEN SPREADING PRECIPITATION
INTO INYO COUNTY. ACCUMULATING SNOW FELL ABOVE 9000 FEET IN THE
SOUTHERN SIERRA NEVADA AND WHITE MOUNTAINS WHILE ONLY VERY LIGHT
RAINFALL FELL IN THE OWENS VALLEY.
