AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
257 PM PDT SUN JUN 28 2015

.SYNOPSIS...ISOLATED TO SCATTERED THUNDERSTORMS...PRIMARILY OVER THE
HIGHER ELEVATIONS WILL BE COMMON DURING THE AFTERNOON AND EVENING
HOURS INTO MID WEEK. TEMPERATURES WILL CONTINUE TO REMAIN ABOVE
NORMAL THROUGH THE PERIOD.
&&

.SHORT TERM...THE RIDGE OF HIGH PRESSURE IS CURRENTLY CENTERED OVER
THE NORTHEAST CORNER OF NEVADA AND NORTHWEST CORNER OF UTAH. THE
RIDGE WILL MAKE LITTLE PROGRESS OVER THE NEXT 24 HOURS AND ALLOW A
SOUTHEAST TO SOUTHERLY FLOW ACROSS ARIZONA...CALIFORNIA...AND
SOUTHERN NEVADA ALLOWING A MOIST FLOW TO CONTINUE TO AID IN THE
GENERATION OF AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS. CLOUD
COVER HAS HAMPERED ANY THUNDERSTORM DEVELOP THIS AFTERNOON OVER MUCH
OF INYO AND SAN BERNARDINO COUNTIES...BUT A FEW SHOWERS HAVE
OCCURRED OVER THE SIERRA AND IN THE EXTREME WESTERN PORTIONS OF SAN
BERNARDINO COUNTY. ELSEWHERE...SCATTERED THUNDERSTORMS HAVE
DEVELOPED OVER EASTERN MOHAVE COUNTY AND ARE SLOWLY MOVING OFF TO
THE WEST. THIS MOVEMENT AND OUTPUT FROM SEVERAL RECENT HRRR RUNS
INDICATE THE POTENTIAL FOR OUTFLOW FROM THESE STORMS TO REACH THE
LAKE MEAD NATIONAL RECREATION AREA LATE THIS AFTERNOON AND EARLY
THIS EVENING.

A WEAK WAVE WILL WORK ITS WAY TO THE NORTHWEST AND INTO SOUTHERN
CALIFORNIA TONIGHT...WHICH MAY BE ENOUGH TO TRIGGER SOME LIGHT
SHOWERS OR AN ISOLATED THUNDERSTORM IN SAN BERNARDINO COUNTY
TONIGHT. THIS WAVE WILL ALSO CONTINUE TO PROVIDE MID AND HIGH LEVEL
MOISTURE AND CLOUDS.

ON MONDAY...WITH NO REAL TRIGGERS TO INITIATE CONVECTION...TERRAIN
WILL BE THE MAIN DRIVER AND ISOLATED TO SCATTERED THUNDERSTORMS ARE
POSSIBLE ACROSS MUCH OF THE HIGHER TERRAIN MONDAY AFTERNOON AND
EVENING. SIMILAR CONDITIONS ARE EXPECTED ONCE AGAIN ON TUESDAY.
TEMPERATURES ON MONDAY AND TUESDAY WILL CONTINUE TO REMAIN SEVERAL
DEGREES ABOVE THEIR SEASONAL NORMS.

.LONG TERM...THE LATEST MEDIUM RANGE MODELS ARE IN PRETTY GOOD
AGREEMENT THROUGH FRIDAY WITH CENTERING AN AREA OF HIGH PRESSURE
DIRECTLY OVER NORTHERN NEVADA WEDNESDAY THROUGH FRIDAY. WHICH WILL
RESULT IN ELEVATED TEMPERATURES WITH DIMINISHING CHANCES FOR
THUNDERSTORMS. WHILE LIMITED MOISTURE WILL CONTINUE TO CIRCULATE
UNDER THE RIDGE...THIS PATTERN WILL BRING DRY AIR OVER IDAHO AND
UTAH TOWARD SOUTHERN NEVADA WHICH WILL DECREASE SLIGHTLY THE CHANCES
FOR THUNDERSTORMS GOING INTO THE WEEKEND. HOWEVER...WILL KEEP THE
MENTION OF A SLIGHT CHANCE OF THUNDERSTORMS OVER THE HIGHER TERRAIN
UNTIL CONFIDENCE IN THIS SCENARIO BECOMES MORE SOLID. MEANWHILE...
THE STRONG RIDGE OVERHEAD WILL KEEP HIGH TEMPS IN THE 108-113 RANGE
OVER MUCH OF THE MOJAVE DESERT AND COLORADO RIVER REGION. THE ECMWF
GUIDANCE INDICATES THIS TREND BETTER THAN THE GFS AND I ADJUSTED
TEMPERATURES UPWARD ACCORDINGLY.
&&

.FIRE WEATHER...THUNDERSTORM CHANCES WILL SLOWLY INCREASE THROUGH
THE EARLY PART OF THE WEEK WITH MAINLY HIGH BASED STORMS DEVELOPING
OVER THE HIGHER TERRAIN. THE MAIN THREATS WITH THUNDERSTORMS THIS
EVENING WILL BE GUSTY WINDS AND LIGHTNING. THERE IS A BETTER CHANCE
FOR WETTING RAINS FROM MONDAY THROUGH WEDNESDAY...BUT THE THREAT FOR
GUSTY WINDS AND LIGHTNING WILL CONTINUE.
&&

.AVIATION...AN ISOLATED THUNDERSTORM IS POSSIBLE OVER THE SPRING
MOUNTAINS DURING THE EVENING HOURS. ADDITIONAL THUNDERSTORMS OVER
MOHAVE COUNTY WILL PUSH OUTFLOW TO THE EAST AND TOWARD LAKE MEAD
DURING THE EVENING. SOUTHERLY WINDS WILL CONTINUE INTO THE EVENING WITH
GUSTS OF AROUND 20 KTS WITH WINDS AGAIN DROPPING OFF AROUND
MIDNIGHT. AN ISOLATED THUNDERSTORM IS POSSIBLE IN THE VICINITY OF
KLAS ON MONDAY...WITH SCATTERED THUNDERSTORMS EXPECTED IN THE
SPRING MOUNTAINS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...WINDS GENERALLY SOUTHWEST AROUND 10-15 KTS DURING THE
EVENING HOURS WITH GUSTS OF 20-30 KTS. CHANCES OF TSRA WILL BE
FAVORED OVER THE HIGHER TERRAIN TODAY...ESPECIALLY IN THE SIERRA AND
IN MOHAVE COUNTRY. CONVECTIVE ACTIVITY DECREASING BETWEEN 03Z AND
07Z MONDAY. MAINLY SCT-BKN CLOUDS AOA 15K FEET WITH BASES AS LOW AS
6K-10K FEET NEAR ANY SHRA/TSRA. SIMILAR CIGS WITH SLIGHTLY MORE
COVERAGE IN CONVECTIVE ACTIVITY EXPECTED ON MONDAY.
&&

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION IS NOT EXPECTED AT THIS TIME.
HOWEVER...SPOTTERS ARE ENCOURAGED TO REPORT ANY SIGNIFICANT
WEATHER CONDITIONS ACCORDING TO STANDARD OPERATING PROCEDURES.
