AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
240 PM PDT THU JUL 17 2014

.SYNOPSIS...ISOLATED THUNDERSTORMS WILL STILL BE POSSIBLE ACROSS
MAINLY THE SIERRA AND THE SOUTHERN GREAT BASIN THROUGH SUNDAY WHILE
THE MOJAVE DESERT REMAINS DRY. HOT AND DRY CONDITIONS ARE EXPECTED
OVER THE ENTIRE REGION FOR THE BEGINNING OF NEXT WEEK.
&&

.SHORT TERM...THROUGH SUNDAY NIGHT...MID/UPPER HIGH WILL PERSIST
OVER THE AREA THROUGH FRIDAY LEADING TO HOT AND MOSTLY DRY
CONDITIONS. A BAND OF LINGERING MOISTURE AND WEAK INSTABILITY WILL
ALSO PERSIST ACROSS THE NORTHERN PART OF THE FORECAST AREA LEADING
TO ISOLATED THUNDERSTORMS THROUGH EARLY THIS EVENING AND AGAIN
FRIDAY AFTERNOON. HOWEVER...THE MODELS ARE SHIFTING THAT BAND OF
MOISTURE AND INSTABILITY A LITTLE MORE TO THE NORTH FRIDAY SO
THUNDERSTORMS MAY BE JUST LIMITED TO EXTREME NORTHERN
INYO...ESMERALDA AND NORTHERN LINCOLN COUNTIES. THE AREA OF HIGH
PRESSURE WILL SHIFT A BIT EAST ON SATURDAY WITH THE MODELS IN
AGREEMENT BRINGING A SHORTWAVE UP FROM THE SOUTH INTO SOUTHERN
CALIFORNIA BY THE AFTERNOON. THE MODELS ARE NOT HOWEVER BRINGING A
BIG INCREASE IN MOISTURE UP WITH THE WAVE AND NOT GENERATING MUCH
INSTABILITY EITHER. I DID THINK IT WAS WORTH BUMPING POPS UP A BIT
AND INDICATED A SLIGHT CHANCE OF THUNDERSTORMS FOR SOME OF THE
HIGHER TERRAIN. I WOULD NOT BE SURPRISED TO SEE THE MODELS START
BRINGING IN MORE MOISTURE WITH THIS FEATURE IN LATER MODEL RUNS.
THUNDERSTORM CHANCES WILL CONTINUE IN THE NORTHERN PART OF THE CWA
SUNDAY AS THE SHORTWAVE CONTINUES TO TRACK NORTH BUT DRYING IS
INDICATED IN THE SOUTH BEHIND THE SHORTWAVE.

.LONG TERM...MONDAY THROUGH THURSDAY...A STRONG RIDGE IN THE
VICINITY OF NEW MEXICO WILL PROVIDE A DRY SOUTHWEST FLOW OVER MUCH
OF THE FORECAST AREA ON MONDAY. BOTH THE ECMWF AND GFS ARE
INDICATING A WEAK IMPULSE MOVING NORTHWARD UP THE COLORADO RIVER
VALLEY DURING THE DAY ON TUESDAY. AT THIS POINT I HAVE INCREASED
POPS MARGINALLY OVER THE COLORADO RIVER VALLEY AND MOHAVE COUNTY ON
TUESDAY...BUT WILL NEED TO MONITOR TO SEE IF THERE IS ANY
SUBSTANTIAL MOISTURE PUSH ALONG WITH THE MID AND UPPER LEVEL WAVE.
ANOTHER FEATURE TO KEEP TRACK OF BY MID WEEK WILL BE THE POTENTIAL
DEVELOPMENT OF A TROPICAL SYSTEM IN THE EASTERN PACIFIC AS A WAVE
MOVES OFF THE CENTRAL MEXICAN COAST. HOW CLOSE A TROPICAL SYSTEM
TRAVERSES THE MOUTH OF THE GULF OF CALIFORNIA WILL IMPACT THE
POTENTIAL FOR A GULF SURGE. BY THURSDAY THE STRONG RIDGE OF HIGH
PRESSURE WILL MOVE SLIGHTLY WEST AND BE CENTERED IN THE VICINITY OF
THE FOUR CORNERS. TEMPERATURES WILL TREND UPWARD AND HAVE MADE
LITTLE CHANGE TO THE TEMPERATURE FORECAST AT THIS POINT. THE EXACT
POSITION OF THE RIDGE AND ANY TROPICAL DEVELOPMENT WILL HAVE A
SIGNIFICANT IMPACT ON THE TEMPERATURES AND PRECIP FORECAST. &&

.AVIATION...FOR MCCARRAN...SOUTH WINDS 10-15 KTS WITH GUSTS 20-25
KTS THROUGH EARLY THIS EVENING. SOUTH/SOUTHWEST WINDS AROUND 10 KTS
AFTER 03Z.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS CAN BE
EXPECTED THROUGH THIS EVENING MAINLY FROM NORTHERN INYO COUNTY
ACROSS ESMERALDA COUNTY INTO NORTHERN LINCOLN COUNTY WITH GUSTY
OUTFLOW WINDS POSSIBLE. AWAY FROM THUNDERSTORM INFLUENCES...WINDS
WILL MAINLY BE SOUTHWEST 5-15 KTS. THUNDERSTORM CHANCES WILL SHIFT A
BIT FARTHER NORTH FOR FRIDAY AFTERNOON AND EVENING.
&&

.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...CZYZYK
