AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
930 AM PDT SAT JUN 13 2015

.SYNOPSIS...LINGERING MOISTURE AND WEAK INSTABILITY WILL RESULT IN
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS OVER MAINLY THE
HIGHER TERRAIN TODAY. A DRY...WESTERLY FLOW FROM SUNDAY ONWARD WILL
BRING HOT AND DRY JUNE WEATHER CONDITIONS TO THE AREA INTO NEXT WEEK
WITH DAYTIME TEMPERATURES SEVERAL DEGREES ABOVE NORMAL.
&&

.UPDATE...WEAK UPPER LOW WHICH WAS OVER CENTRAL CALIFORNIA YESTERDAY
HAS SHIFTED SOUTHEAST AND IS NEAR YUMA THIS MORNING. A POSITIVE TILT
TROUGH EXTENDS FROM THIS LOW NORTHEAST TOWARD THE FOUR CORNERS.
TROUGH AXIS WILL SHIFT EAST TODAY WITH RIDGE OVER THE EASTERN
PACIFIC BUILDING CLOSER TO THE WEST COAST.

WATER VAPOR SHOWS SOME DRYING IN THE UPPER LEVELS IN CALIFORNIA
WHILE LOWER LEVELS REMAIN UNSEASONABLY MOIST FOR MID-JUNE WITH
SURFACE DEWPOINTS IN THE 40S AND LOWER 50S ACROSS THE MOJAVE DESERT.
THE PW VALUE AT LAS VEGAS 0F 0.93 INCHES IS DOWN ABOUT A TENTH OF AN
INCH FROM YESTERDAY. BEST INSTABILITY TODAY LOOKS TO BE NEAR THE
TROUGH AXIS FROM SOUTHERN MOHAVE COUNTY WEST INTO SAN BERNARDINO
COUNTY AND FAR SOUTHERN NEVADA. CONVECTION LOOKS TO BE STARTING
EARLIER TODAY OVER THE HIGHER TERRAIN, INCLUDING THE SPRING
MTNS/SHEEP RANGE. QUICK BURSTS OF HEAVY RAIN AND GUSTY WINDS PRIMARY
THREAT TODAY.

WILL DO ANOTHER UPDATE TO BETTER CAPTURE EARLIER START OF
CONVECTION.
&&

.PREV DISCUSSION...230 AM PDT SAT JUN 13 2015
.SHORT TERM...THROUGH MONDAY NIGHT.

AN UPPER LEVEL DISTURBANCE HAS KEPT SOME ISOLATED CONVECTION GOING
INTO THE WEE HOURS OF THE NIGHT BUT AS OF THIS HOUR IT LOOKS LIKE
MOST OF THE CONVECTION HAS DIMINISHED.  WHILE THE UPPER LEVEL
DISTURBANCE WILL DRIFT SOUTHEASTWARD LATER TODAY...PRECIPITABLE
WATER REMAINS ELEVATED ACROSS THE REGION...ESPECIALLY ALONG AND
SOUTH OF INTERSTATE 15. WHILE CONVECTION SHOULD BE NOTICEABLY WEAKER
AND MORE ISOLATED TODAY...I STILL ANTICIPATE ISOLATED SHOWERS AND
STORMS. THE STEERING FLOW WILL BE QUITE WEAK WHICH WILL WORK TO
ANCHOR ACTIVITY TO THE HIGHER PEAKS...AND I TRENDED THE POP GRID TO
REFLECT HIGHEST CHANCES IN THE MOUNTAINOUS TERRAIN. MOST OF THE
LOWER ELEVATION VALLEY LOCATIONS ACROSS OUR FORECAST AREA SHOULD
REMAIN DRY.

THINGS WILL CONTINUE TO DRY OUT ON SUNDAY BUT SOME VERY ISOLATED
ACTIVITY REMAINS POSSIBLE ACROSS THE HIGHER TERRAIN OF NORTHWEST
ARIZONA AND SOUTHERN NEVADA. DRY CONDITIONS ARE EXPECTED AREA WIDE
BY MONDAY.

OUTSIDE OF CONVECTION...THE BIG STORY WILL BE THE HEAT. TEMPERATURES
WILL BE WARMING INTO THE TRIPLE DIGITS ACROSS MUCH OF THE MOJAVE
DESERT WITH LAS VEGAS WARMING INTO THE LOW 100S TODAY AND BEYOND 105
BY MONDAY. IN DEATH VALLEY AND ALONG THE LOWER COLORADO
RIVER...TEMPERATURES WILL WARM INTO THE 110S BY MONDAY.

.LONG TERM...TUESDAY THROUGH FRIDAY.

CONFIDENCE REMAINS HIGH IN THE FIRST PROLONGED PERIOD OF TRIPLE
DIGIT HEAT IN DESERT LOCALES NEXT WEEK AS WESTERLY TO SOUTHWESTERLY
UPPER LEVEL FLOW IS EXPECTED TO DOMINATE THE REGION THROUGH AT LEAST
NEXT WEEKEND. THIS PATTERN WILL AID IN MIXING...BUMPING AFTERNOON
HIGHS UP A FEW DEGREES EACH AFTERNOON...YIELDING THE HOTTEST DAYS OF
2015 SO FAR BY MID-WEEK. AFTERNOON HIGHS WILL RUN ROUGHLY 6-9
DEGREES ABOVE NORMAL FOR MID-JUNE...RANGING FROM 102-109 ACROSS MOST
DESERT LOCATIONS...WITH LOWER DESERT LOCATIONS SUCH AS DEATH
VALLEY...AND THE COLORADO RIVER VALLEY EASILY EXCEEDING 110 AND
PERHAPS 115 AT TIMES THROUGH LATE WEEK. AT THIS TIME...IT APPEARS
THAT MOST RECORDS WILL REMAIN SAFE NEXT WEEK.

THOUGH IT CONTINUES TO LOOK LIKE WE WILL REMAIN JUST BELOW THE
EXCESSIVE HEAT CRITERIA THRESHOLD OF 110 IN LAS VEGAS NEXT
WEEK...INDIVIDUALS AND ORGANIZATIONS HERE AND IN OTHER DESERT
LOCATIONS ARE ENCOURAGED TO PLAN AHEAD BY CHECKING AIR
CONDITIONERS...VEHICLE MAINTENANCE...ETC...AS WELL AS EXERCISING
HEAT SAFETY DURING THIS PROLONGED PERIOD. REMEMBER...HEAT IS THE
LEADING WEATHER RELATED KILLER IN OUR CWA.

&&

.AVIATION...FOR MCCARRAN...DIURNAL WIND PATTERNS EXPECTED TODAY WITH
WINDS GENERALLY BELOW 9KTS EXPECTED. EASTERLY COMPONENTS FAVORED
MUCH OF THE DAY WITH SOUTHERLY DRAINAGE FLOW EXPECTED OVERNIGHT.
ISOLATED CONVECTION IN THE MOUNTAINS BUT SHOULD MAINLY STAY OUTSIDE
OF THE VALLEY. WHAT WILL NEED TO BE MONITORED IS POTENTIAL OUTFLOW
WINDS FROM NEARBY STORMS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...GENERALLY LIGHT SOUTH OR SOUTHWESTERLY WINDS ARE
EXPECTED ACROSS THE REGION TODAY IN THE 6-12KT RANGE. SOME ISOLATED
CONVECTION POSSIBLE ACROSS THE HIGHER TERRAIN BUT OTHERWISE FAIR
WEATHER EXPECTED. CONVECTIVE TURBULENCE AND GUSTY SURFACE WINDS
LIKELY NEAR STORM ACTIVITY.

&&

.SPOTTER INFORMATION STATEMENT...SPOTTERS ARE ENCOURAGED TO REPORT
ANY SIGNIFICANT WEATHER CONDITIONS ACCORDING TO STANDARD OPERATING
PROCEDURES.

UPDATE...PIERCE
