AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1015 AM PDT FRI JUL 29 2011

.SYNOPSIS...MOISTURE WILL SPREAD NORTH AND WEST THROUGH THE
WEEKEND...WITH CHANCES FOR SHOWERS AND THUNDERSTORMS INCREASING IN
PROBABILITY AND COVERAGE EACH DAY. DRIER AIR WILL BEGIN TO SPREAD
INTO CALIFORNIA MONDAY AND WORK EAST BY MID-WEEK...LIMITING
THUNDERSTORMS TO MAINLY MOHAVE COUNTY BY WEDNESDAY.
&&

.UPDATE...ELEVATED CONVECTION TURNED INTO SCATTERED THUNDERSTORMS
THIS MORNING OVER DEATH VALLEY AND SOUTHERN NYE COUNTY. THIS WAS
APPARENTLY DEVELOPING IN RESPONSE TO AN UPPER LEVEL DISTURBANCE
DEPICTED BY BOTH THE NAM AND GFS WHICH WAS MOVING WESTWARD ACROSS
SOUTHERN NEVADA. SHOWERS WERE ALSO MOVING INTO SOUTHEAST MOHAVE
COUNTY THIS MORNING. INYO...ESMERALDA...CENTRAL NYE AND MOHAVE
COUNTIES SHOULD SEE THE BEST COVERAGE OF THUNDERSTORMS THROUGH THIS
AFTERNOON. THE 12Z LAS VEGAS SOUNDING INDICATED MARGINAL INSTABILITY
WITH LIMITED CAPE BUT THE NAM BUFR SOUNDING SHOWS CAPE INCREASING TO
AROUND 600 J/KG BY THIS AFTERNOON. THE BAND OF CONVECTION OVER
MOHAVE COUNTY WILL BE MOVING TO THE NORTHWEST AND COULD ALSO ENHANCE
THUNDERSTORM DEVELOPMENT IN CLARK COUNTY THIS AFTERNOON. THE
FORECAST WILL BE UPDATED TO INCREASE POPS/WEATHER COVERAGE OVER THE
AFOREMENTIONED FAVORABLE AREAS AND EVEN.
&&

.AVIATION...FOR MCCARRAN...SOUTHEAST WINDS 6-8KTS CAN BE EXPECTED
THROUGH THIS AFTERNOON THEN BECOMING LIGHT SOUTHERLY AROUND 7KTS
THIS EVENING. ISOLATED THUNDERSTORMS ARE POSSIBLE IN THE MORMON MESA
AND PEACH SPRINGS CORRIDORS THIS AFTERNOON AND EVENING. ISOLATED
THUNDERSTORMS ARE ALSO POSSIBLE IN THE MOUNTAINS SURROUNDING THE
VALLEY...BUT WILL KEEP MENTION OUT OF TAF AND ONLY INCLUDE CB. TSRA
COULD CREATE GUSTY AND ERRATIC WINDS FROM ASSOCIATED OUTFLOW
BOUNDARIES.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...SOUTH TO SOUTHEAST WINDS 10KTS OR LESS FOR MUCH OF THE
AREA TODAY WITH THE EXCEPTION OF ANY THUNDERSTORM OUTFLOW BOUNDARIES
THAT MAY CAUSE ERRATIC AND GUSTY WINDS. ISOLATED SHRA AND TSRA WILL
BE POSSIBLE ACROSS MUCH OF THE AREA TODAY IN THE AFTERNOON AND
EVENING WITH THE BEST CHANCES ACROSS THE HIGHER ELEVATIONS AS WELL
AS IN MOHAVE COUNTY.

.PREV DISCUSSION...
320 AM PDT FRI JUL 290 2011

.SHORT TERM...INVERTED TROUGH NEAR THE BIG BEND OF TEXAS MADE LAST
EVENING...CARRYING OVER INTO THIS MORNING BY FAR THE MOST ACTIVE I
HAVE SEEN THE 2011 MONSOON ACROSS NORTHERN MEXICO. EARLY
MORNING SATELLITE SHOWS AND EXTENSIVE DEBRIS SHIELD ENCOMPASSING
MUCH OF ARIZONA WITH CLOUDS TRYING TO EXPAND WESTWARD INTO MOHAVE
COUNTY AND SOUTHEAST CALIFORNIA. UNFORTUNATELY FOR US...DYNAMICS
ASSOCIATED WITH INVERTED TROUGH WILL STAY TO OUR EAST AS FEATURE
SLOWLY MOVES NORTHWARD ACROSS WESTERN NEW MEXICO AND EASTERN ARIZONA
TODAY THROUGH SUNDAY. STRONG HIGH PRESSURE CENTER REMAINS POSITIONED
OVER THE SOUTHERN HIGH PLAINS MID-LEVELS WILL CONTINUE TO MOISTEN
UNDER PREVAILING SOUTHEAST FLOW. NAM BUFR SOUNDING FOR LAS VEGAS
PROGS PW VALUES NEAR 1.30 INCHES THIS AFTERNOON...INCREASING TO
AROUND 1.50 INCHES SATURDAY AND SUNDAY. SLOW STORM MOTION AND WELL
ABOVE NORMAL PW VALUES SUGGEST ANY THUNDERSTORM OVER THE WEEKEND HAS
THE POTENTIAL OF PRODUCING HEAVY RAIN. NOCTURNAL THUNDERSTORMS NOT
OUT OF QUESTION THIS WEEKEND ESPECIALLY IF THERE IS A DISTURBANCE
EMBEDDED IN THE FLOW. THE CLOUDINESS AND INCREASE IN SURFACE
DEWPOINTS WILL LEAD TO BELOW NORMAL TEMPERATURES OVER THE
WEEKEND...WHICH COMES ALONG WITH THAT UNCOMFORTABLE FEEL OF HIGHER
HUMIDITY VALUES.

.LONG TERM...UPPER LEVEL TROUGH APPROACHING THE WEST COAST MONDAY
WILL START TO BRING DRYER AIR INTO THE REGION AND HELP PUSH THE
MONSOONAL MOISTURE FURTHER EAST. MONDAY STILL LOOKS LIKE A FAIRLY
ACTIVE DAY OVER THE EASTERN THIRD OF THE AREA AS DEEPER MOISTURE
REMAINS IN PLACE. ANOTHER FACTOR WILL BE TROPICAL SYSTEM DON THAT IS
CURRENTLY OVER THE WESTERN GULF OF MEXICO. MODELS AND NHC ARE TAKING
THIS TRACK A BIT FURTHER SOUTH THAN 24HRS AGO AND TRACK THE
REMAINING MOISTURE ACROSS NORTHERN MEXICO. ITS POSSIBLE THAT THIS
MOISTURE COULD GET CAUGHT UP IN THE FLOW AND ADD ADDITIONAL MOISTURE
TO THE EASTERN AREAS OF THE CWA. THIS WOULD LIKELY OCCUR MONDAY OR
TUESDAY SO THIS WILL NEED TO BE WATCHED. TROUGH IS FORECAST TO
CONTINUE TO DIG NEXT WEDNESDAY THROUGH FRIDAY PUSHING MUCH OF THE
MOISTURE EAST AND LEAVING ONLY THE EASTERN HALF OF MOHAVE COUNTY IN
THE THUNDERSTORM THREAT. SOUTHWEST FLOW IS EXPECTED OVER THE
REMAINDER OF THE AREA WITH DRY CONDITIONS. TEMPERATURES WILL REMAIN
CLOSE TO OR SLIGHTLY BELOW NORMAL THROUGH THE WEEK.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF NORTHWEST
ARIZONA...CALIFORNIA AND SOUTHERN NEVADA.

.DAY ONE...TODAY AND TONIGHT

ISOLATED SHOWERS AND THUNDERSTORMS WILL OCCUR AS MONSOON MOISTURE
INCREASES FROM THE SOUTHEAST. THE THREAT FOR HAZARDOUS WEATHER IS
LOW.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

THE THREAT OF HAZARDOUS WEATHER INCREASES SATURDAY THROUGH MONDAY
AS THERE IS A HIGHER PROBABILITY OF SHOWERS AND THUNDERSTORMS.
THERE WILL BE A GREATER THREAT OF FLASH FLOODING FROM HEAVY
RAINFALL. STORMS WILL ALSO PRODUCE GUSTY WINDS WHICH COULD CATCH
SOME BOATERS OFF GUARD ON AREA LAKES AS WELL AS DANGEROUS
LIGHTNING. THE HIGHER HUMIDITY VALUES WILL LEAD TO A FEELING OF
GREATER DISCOMFORT.

DRIER AIR MOVING INTO CALIFORNIA EARLY IN THE WEEK WILL
EVENTUALLY LIMIT ANY THUNDERSTORMS TO MOHAVE COUNTY BY THE MIDDLE
OF NEXT WEEK.

.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.
