AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
143 PM PDT WED JUL 16 2014

.SYNOPSIS...DRIER AIR WILL CONTINUE TO FILTER INTO THE AREA DURING
THE REST OF THE WEEK. ISOLATED THUNDERSTORMS WILL STILL BE POSSIBLE
ACROSS MAINLY THE SOUTHERN GREAT BASIN WHILE THE MOJAVE DESERT
REMAINS DRY. HOT AND DRY CONDITIONS ARE EXPECTED FOR THE BEGINNING
OF NEXT WEEK.
&&

.SHORT TERM...THROUGH SATURDAY NIGHT...ISOLATED THUNDERSTORMS HAVE
BEEN FORMING ABOUT WHERE EXPECTED...OVER THE SPRING MOUNTAINS AND
ACROSS THE NORTHERN CWA WHERE AN AREA OF DEFORMATION WAS LOCATED
ALONG WITH A BAND OF FAIRLY MOIST AND UNSTABLE AIR. THIS ACTIVITY
SHOULD DECREASE DURING THE EVENING HOURS BUT THERE IS A SLIGHT
POSSIBILITY OF SOMETHING OVERNIGHT IN ESMERALDA COUNTY AS THE MODELS
GENERATE A WEAK VORT MAX AND BRING IN OVER THE RIDGE ACROSS THAT
AREA. THE DEFORMATION ZONE WILL WEAKEN OVERNIGHT AND THURSDAY BUT
THE MODELS CONTINUE TO INDICATE A BAND OF WEAK INSTABILITY AND CAPE
FROM NORTHERN INYO COUNTY ACROSS THROUGH LINCOLN COUNTY THURSDAY
AFTERNOON. I KEPT SLIGHT CHANCE TO CHANCE POPS ACROSS THIS AREA WITH
DRY CONDITIONS OVER THE MOJAVE DESERT. THE AREA OF MOISTURE AND
INSTABILITY WILL CONTINUE TO WEAKEN AND LIFT SLOWLY NORTH WITH
THUNDERSTORM CHANCES LIMITED TO MAINLY THE FAR NORTHWEST AND
NORTHEAST CORNERS OF THE FORECAST AREA FRIDAY AND SATURDAY.
MEANWHILE...HIGH PRESSURE OVER THE SOUTHWEST U.S. WILL KEEP
SEASONABLY HOT TEMPERATURES GOING THROUGH SATURDAY.

.LONG TERM...SUNDAY THROUGH WEDNESDAY...AFTER AN ACTIVE START TO THE
MONSOON IT LOOKS LIKE A RATHER QUIET PERIOD IS AHEAD AS THE FLOW
TAKES A MORE SOUTHWESTERLY ORIENTATION...SHUNTING THE BEST MOISTURE
AND INSTABILITY FURTHER EAST.  LATEST ECMWF AND CANADIAN MODELS
BEGIN TO CREEP MOISTURE BACK INTO MOHAVE COUNTY TUESDAY AND
WEDNESDAY WHILE THE GFS DEVELOPS A RATHER BROAD AND DRY
SOUTHWESTERLY FLOW IN RESPONSE TO STRONG TROUGHING DIGGING ACROSS
THE WEST COAST.  GIVEN THE TIME OF YEAR AM INCLINED TO BELIEVE THE
EC/CANADIAN SOLUTIONS AS TROUGHING OF THE MAGNITUDE THE GFS SUGGESTS
WOULD BE SOMEWHAT ANOMALOUS. THEREFORE I SLOWLY RAMPED POPS UP IN
MOHAVE COUNTY TUESDAY ONWARD. BUT NEVERTHELESS...AM NOT EXPECTING
ANY BIG SURGES IN MONSOONAL MOISTURE FOR THE FORESEEABLE SEVEN DAYS
AHEAD.

AS FOR TEMPERATURES...GIVEN THE MOSTLY DRY CONDITIONS EXPECTED AND
STRENGTHENING HIGH PRESSURE BY MIDWEEK...TEMPERATURES WILL BE
CREEPING UPWARDS FOR THE EXTENDED PERIOD. I TRENDED TEMPERATURES
ABOVE GUIDANCE AS MAJOR MODELS AGREE IN BUILDING 595+ HEIGHTS ACROSS
THE FOUR CORNERS. THIS WILL LEAD TO VERY HOT TEMPERATURES RISING
SEVERAL DEGREES ABOVE NORMAL.
&&

.AVIATION...FOR MCCARRAN...SOUTH/SOUTHWEST WINDS AROUND 10 KTS
EXPECTED LATE THIS AFTERNOON THROUGH TONIGHT BECOMING LIGHT AND
VARIABLE THURSDAY MORNING. ISOLATED THUNDERSTORMS WILL BE POSSIBLE
THIS AFTERNOON AND EVENING OVER THE SPRING MOUNTAINS AND SHEEP RANGE
AND IN THE BEATTY...MORMON MESA AND PEACH SPRINGS CORRIDORS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS CAN BE
EXPECTED MAINLY FROM THE SOUTHERN SIERRA...ACROSS CENTRAL NEVADA AND
NORTHWEST ARIZONA TODAY WITH GUSTY OUTFLOW WINDS POSSIBLE. AWAY FROM
THUNDERSTORM INFLUENCES...WINDS WILL MAINLY BE SOUTHWEST 5-15 KTS.
&&

.SPOTTER INFORMATION STATEMENT...SPOTTER ACTIVATION IS NOT EXPECTED
THROUGH THE REST OF THIS WEEK. HOWEVER...SPOTTERS ARE ENCOURAGED
TO REPORT ANY SIGNIFICANT WEATHER CONDITIONS ACCORDING TO STANDARD
OPERATING PROCEDURES. &&

SHORT TERM/AVIATION...HARRISON
LONG TERM...OUTLER
