AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
858 AM PDT TUE JUL 1 2014
.SYNOPSIS...THE HOTTEST TEMPERATURES SO FAR THIS YEAR ARE EXPECTED
THROUGH MID WEEK UNDER AN AREA OF HIGH PRESSURE. THERE WILL BE A
SLIGHT CHANCE OF THUNDERSTORMS NEAR THE SOUTHERN SIERRA AND THE
MOUNTAINS OF THE SOUTHERN GREAT BASIN TODAY...THEN ADDITIONAL
MOISTURE INCREASING FROM THE SOUTHEAST WILL LEAD TO A SLIGHT CHANCE
OF THUNDERSTORMS IN NORTHWEST ARIZONA LATE IN THE WEEK.
&&
.UPDATE...MODELS CONTINUE TO INDICATE JUST ENOUGH MOISTURE AND
INSTABILITY FOR ISOLATED THUNDERSTORMS THIS AFTERNOON MAINLY IN THE
FAR NORTHWEST CORNER OF THE CWA AND OVER NORTHERN MOHAVE COUNTY.
CANNOT TOTALLY RULE OUT A STORM OVER THE SPRING MOUNTAINS AND
MOUNTAINS OF NORTHERN LINCOLN COUNTY. 12Z SOUNDING INDICATES A HIGH
OF 111 TODAY IN LAS VEGAS SO THE 112 WE ARE FORECASTING LOOKS PRETTY
GOOD. THE EXCESSIVE HEAT WARNING CONTINUES THROUGH WEDNESDAY
EVENING. NO UPDATES ANTICIPATED THIS MORNING. -HARRISON-

.PREV DISCUSSION...
230 AM PDT TUE JUL 1 2014
.SHORT TERM...THROUGH WEDNESDAY NIGHT...SATELLITE LOOP SHOWED WEAK
SHORTWAVE TROUGH ROLLING INTO THE MONTEREY BAY AREA...WITH AN
ASSOCIATED BAND OF CLOUDS FROM SAN FRANCISCO THROUGH RENO AND INTO
NORTHERN LINCOLN COUNTY. ELSEWHERE ACROSS OUR CWA SKIES WERE CLEAR.
SURFACE OBS SHOWED LIGHT WINDS AND VERY WARM TEMPERATURES /STILL 95F
AT KLAS AT 230 AM/. THE HEAT IS THE MAIN CONCERN OF THE SHORT
TERM...AND THE EXCESSIVE HEAT WARNING THROUGH TOMORROW LOOKS GOOD.
SECONDARY CONCERN IS THUNDERSTORM DEVELOPMENT THIS AFTERNOON. THE
SHORTWAVE TROUGH WILL HELP TRIGGER DEVELOPMENT IN AN ARC FROM THE
SIERRA CREST THROUGH THE SOUTHERN GREAT BASIN AND DOWN TO THE
MOUNTAINS OF CLARK AND MOHAVE COUNTIES...WITH THE MAIN CONCERNS
BEING LIGHTNING...ERRATIC WINDS...AND WILDFIRE STARTS. AS THE
SHORTWAVE TROUGH MOVES SLOWLY EAST TOMORROW...THE FLOW WILL TURN
MORE SOUTHWESTERLY OVER OUR AREA...WHICH SHOULD LIMIT ANY
THUNDERSTORM CHANCES TO THE MOUNTAINS OF THE FAR EASTERN CWA.
.LONG TERM...THURSDAY THROUGH TUESDAY...HOT TEMPERATURES WILL
CONTINUE LATE THIS WEEK AND THROUGH EARLY NEXT WEEK AS A STRONG
RIDGE REMAINS ANCHORED TO THE FOUR CORNERS AND GREAT BASIN REGIONS.
WE WILL ALSO BE WATCHING INCREASING AMOUNTS OF MONSOONAL MOISTURE
CREEPING INTO ARIZONA AS EASTERLY FLOW BECOMES BETTER ESTABLISHED
AROUND THE STRONG HIGH. TEMPERATURES THROUGH THE PERIOD WILL REMAIN
SEVERAL DEGREES ABOVE NORMAL, WITH SOME SLIGHT RELIEF POSSIBLE OVER
THE WEEKEND IN MOHAVE COUNTY THANKS TO ADDED MOISTURE AND CLOUD
COVER.
LOOKS LIKE THE FIRST REAL PUSH OF MONSOON MOISTURE WILL MAKE ITS WAY
INTO CENTRAL AND SOUTHERN ARIZONA THURSDAY, AND BEGIN TO EMERGE
ACROSS NORTHWEST ARIZONA FRIDAY. THIS PUSH WILL BE ENHANCED
SOMEWHAT BY THE PRESENCE OF A WEAK INVERTED TROUGH MOVING ALONG THE
SOUTHERN PERIPHERY OF THE WESTERN U.S. RIDGE. WIDESPREAD NEGATIVE
LIFTED INDICES ARE FORECAST ACROSS MOHAVE COUNTY BY THE ECMWF/AND TO
A LESSER DEGREE THE GFS/ BY FRIDAY AFTERNOON AND EVEN MORE SO BY
SATURDAY AFTERNOON. THIS SHOULD RESULT IN INCREASING COVERAGE OF
THUNDERSTORMS BY FRIDAY WITH ISOLATED TO SCATTERED STORM COVERAGE
EXPECTED THROUGH THE WEEKEND. ADDITIONALLY, THE ADDED CLOUD COVER
WILL KEEP TEMPERATURES DOWN A BIT IN MOHAVE COUNTY. FURTHER NORTH
AND WEST, FORECAST REMAINS DRY WITH LIMITED MOISTURE AND INSTABILITY
AVAILABLE FOR ANY THUNDER CHANCES. WE WILL HOWEVER NEED TO WATCH
OUTFLOWS FROM ARIZONA AND NORTHWEST MEXICO FOR ANY UNFORESEEN
MOISTURE INCREASES.
NEXT WEEK, HIGH PRESSURE WILL REMAIN IN THE SAME GENERAL LOCATIONS
WITH THE MONSOON FLOW PERSISTING ACROSS ARIZONA. KEPT TEMPERATURES
ABOVE CLIMO ALONG WITH SLIGHT THUNDER CHANCES IN MOHAVE COUNTY.
&&
.AVIATION...FOR MCCARRAN...EASTERLY WIND COMPONENTS WILL CONTINUE TO
DEVELOP AT THE TERMINAL IN THE LATE MORNING AND EARLY AFTERNOON EACH
DAY THROUGH WEDNESDAY. THERE WILL BE A SLIGHT CHANCE OF
THUNDERSTORMS THIS AFTERNOON AND EVENING OVER THE SPRING MOUNTAINS
AND IN THE MORMON MESA CORRIDOR...WITH THE MAIN THREAT BEING ERRATIC
GUSTY WINDS. VERY HOT TEMPERATURES WILL RESULT IN HIGH DENSITY
ALTITUDES AND LOW LEVEL TURBULENCE EACH DAY.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...VERY HOT TEMPERATURES WILL RESULT IN HIGH DENSITY
ALTITUDES AND LOW LEVEL TURBULENCE EACH DAY THROUGH WEDNESDAY. THERE
WILL BE A SLIGHT CHANCE OF THUNDERSTORMS THIS AFTERNOON AND EVENING
FROM THE SIERRA NEVADA ACROSS THE HIGHER TERRAIN OF THE SOUTHERN
GREAT BASIN AND OVER THE MOUNTAINS OF CLARK AND MOHAVE
COUNTIES...WITH THE MAIN THREAT BEING ERRATIC GUSTY WINDS.
&&
.FIRE WEATHER...A WEAK SHORTWAVE MAY TRIGGER ISOLATED THUNDERSTORMS
OVER THE HIGHER TERRAIN OF SOUTHERN NEVADA...NORTHWEST ARIZONA AND
NORTHERN INYO COUNTY TUESDAY AFTERNOON AND EVENING. HOWEVER...IT
LOOKS LIKE COVERAGE WILL BE VERY ISOLATED AND NOT ENOUGH TO JUSTIFY
A RED FLAG WARNING FOR DRY LIGHTNING. CONFIDENCE IS NOT VERY HIGH
THAT WE WILL EVEN SEE THUNDERSTORMS DEVELOP AT ALL...MAYBE JUST MORE
EXTENSIVE CUMULUS DEVELOPMENT.
