AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
938 AM PDT THU JUL 9 2015

.SYNOPSIS...LOW PRESSURE ALONG THE CENTRAL CALIFORNIA COAST WILL
SPREAD DRIER...COOLER AIR ACROSS THE SOUTHERN HALF OF THE FORECAST
AREA TODAY. INCREASING INSTABILITY WILL COUPLE WITH LIMITED MOISTURE
TO GENERATE THUNDERSTORMS OVER INYO...ESMERALDA...CENTRAL
NYE...LINCOLN AND NORTHERN MOHAVE COUNTIES THROUGH TONIGHT. MAINLY
DRY CONDITIONS AND BELOW NORMAL TEMPERATURES ARE EXPECTED FRIDAY AND
OVER THE WEEKEND.
&&

.UPDATE...UPPER LOW MOVING ON SHORE NEAR CENTRAL CALIFORNIA WILL
HELP ENHANCE FAIRLY WIDESPREAD THUNDERSTORMS OVER INYO COUNTY TODAY.
SO FAR MOST OF THE DEVELOPMENT HAS BEEN ON THE WESTERN SIERRA
SLOPES...BUT STORMS HAVE BEEN STARTING TO INCREASE OVER THE EASTERN
SLOPES WITH A FEW LIGHTNING STRIKES NOTED. WITH THE CLOSE PROXIMITY
TO THE LOW STORM MOTION WILL BE SLOW WHICH COULD LEAD TO FLASH
FLOODING PROBLEMS ALONG WITH HAIL SINCE THE 0/-20 DEG C LEVELS ARE
LOW. AWAY FROM THE SIERRA HIRES MODELS INDICATE SHOWER/THUNDERSTORM
DEVELOPMENT OVER NORTHERN CLARK...LINCOLN AND NORTHERN MOHAVE
COUNTIES...WITH LESSER CHANCES OVER FAR EASTERN SAN BERNARINO AND
CENTRAL AND SOUTHERN CLARK COUNTIES. ANY STORMS THAT DO DEVELOP OVER
THESE AREAS WILL MOVE RATHER FAST AS STORM MOTION IS AROUND 30KTS.

PREV DISCUSSION
241 AM PDT THU JUL 9 2015

.SHORT TERM...THURSDAY THROUGH SATURDAY NIGHT...

WATER VAPOR IMAGERY SHOWS AN UPPER LEVEL LOW SPINNING ALONG THE
CENTRAL CALIFORNIA COAST THIS MORNING AND AT THE BASE OF THE TROUGH,
MODELS HAVE A 110KT JET PUSHING INTO SOUTHERN CALIFORNIA THAT WILL
PROVIDE SUPPORT FOR THUNDERSTORM DEVELOPMENT TODAY. AS THE LOW MOVES
EAST ACROSS CENTRAL CAL THROUGH THE DAY, THUNDERSTORMS ARE EXPECTED
TO BREAK OUT OVER PORTIONS OF THE NORTHERN FORECAST AREA WHILE
DRIER, MORE STABLE CONDITIONS INHIBIT DEVELOPMENT IN THE SOUTHERN
AREAS. LOCAL MODELS DEVELOP PRECIPITATION OVER INYO, ESMERALDA,
CENTRAL NYE AND WESTERN CLARK AND WESTERN LINCOLN COUNTIES BY MID
DAY THEN SPREAD IT INTO EASTERN LINCOLN, PORTIONS OF CENTRAL AND
EASTERN CLARK AND NORTHERN MOHAVE COUNTIES THIS AFTERNOON AND
EVENING. WITH PWAT VALUES OF .5-.8 INCHES AREA WIDE, FLASH FLOODING
BECOMES LESS OF A CONCERN WITH STORMS TODAY AND INCREASING SHEAR
POINTS TO STORMS CAPABLE OF PRODUCING STRONG WINDS AND HAIL.
TEMPERATURES TODAY ARE EXPECTED TO BE WELL BELOW NORMAL AND THIS
WILL CONTINUE INTO FRIDAY AND SATURDAY AS TROUGHING SETTLES IN OFF
THE WEST COAST.

.LONG TERM...SUNDAY THROUGH THURSDAY.

THE LATEST MEDIUM RANGE MODELS CONTINUE TO INDICATE A DRY SOUTHWEST
FLOW REMAINING IN PLACE ACROSS SOUTHEAST CALIFORNIA AND SOUTHERN
NEVADA MUCH OF NEXT WEEK DUE TO A MEAN TROUGH HOLDING ALONG THE WEST
COAST. AN AREA OF HIGH PRESSURE IS FORECAST TO BE CIRCULATING OVER
EASTERN NEW MEXICO AND NORTHERN TEXAS THROUGH THE MIDDLE OF NEXT
WEEK. THE GFS INDICATES SOUTHERLY FLOW OVER WESTERN ARIZONA MAY
BRING SOME MOISTURE UP INTO MOHAVE COUNTY AS EARLY AS SUNDAY THEN
THE MOISTURE BOUNDARY REMAINS NEAR MOHAVE COUNTY THROUGH AT LEAST
THE MIDDLE OF THE WEEK. A SLIGHT CHANCE OF THUNDERSTORMS WILL REMAIN
IN PORTIONS OF OUR NORTHWEST ARIZONA ZONES ACCORDINGLY.
OTHERWISE...THIS PATTERN WILL RESULT IN SOUTHWEST BREEZES OF 10 TO
20 MPH EACH AFTERNOON AND TEMPERATURES INCREASING A DEGREE OR TWO
SUNDAY AND MONDAY LEADING TO NEAR NORMAL READINGS MUCH OF NEXT WEEK
WITH HIGHS OF 103 TO 109 ACROSS THE MOJAVE DESERT AND COLORADO RIVER
VALLEY ZONES.
&&

.AVIATION...FOR MCCARRAN...SOUTHERLY WINDS AROUND 10-12 KTS THROUGH
15Z THEN BECOMING SOUTHEAST FOR A FEW HOURS BEFORE TURNING BACK TO
THE SOUTH OR SOUTHWEST WINDS WITH GUSTS UP TO 30KTS. THUNDERSTORMS
WILL MAINLY BE CONFINED TO AREAS NORTH OF LAS VEGAS...BUT ITS
POSSIBLE THAT A FEW STORMS COULD DEVELOP IN THE SPRING MOUNTAINS IN
THE AFTERNOON AND OUTFLOW COULD BECOME AN ISSUE AT THE AIRPORT
COMPLEX.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...THUNDERSTORMS ARE EXPECTED AGAIN TODAY OVER MAINLY
INYO...CENTRAL NYE...ESMERALDA...LINCOLN AND NORTHERN MOHAVE
COUNTIES. WINDS OVER SAN BERNARDINO...CLARK AND SOUTHERN MOHAVE
COUNTIES WILL SEE GUSTS UP TO 30 KTS OUT OF THE SOUTH AFTER 17Z WITH
WINDS AROUND 10-15 KTS ELSEWHERE.
&&

.SPOTTER INFORMATION STATEMENT...SPOTTERS ARE ENCOURAGED TO REPORT
ANY SIGNIFICANT WEATHER CONDITIONS ACCORDING TO STANDARD OPERATING
PROCEDURES.
