AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
200 PM PDT MON AUG 19 2013

.SYNOPSIS...ISOLATED TO SCATTERED THUNDERSTORMS ARE EXPECTED ACROSS
MUCH OF THE AREA THROUGH TUESDAY BEFORE DRYING BEGINS TO TAKE PLACE
FROM THE WEST ON WEDNESDAY. THIS WILL RESULT IN THUNDERSTORMS BEING
CONFINED TO MAINLY MOHAVE COUNTY FOR THE END OF THE WEEK...HOWEVER
THUNDERSTORMS ARE EXPECTED TO MOVE BACK SOUTHERN NEVADA AND
SOUTHEAST CALIFORNIA LATE IN THE WEEKEND. TEMPERATURES WILL BE NEAR
NORMAL THROUGH THE PERIOD.
&&

.SHORT TERM...TONIGHT THROUGH WEDNESDAY...THE COOLED AIRMASS CAUSED
FROM SUNDAYS STORMS IS DELAYING THE ONSET OF CONVECTION AND MAY
CONTINUE TO HAMPER IT OVER SOUTHERN NEVADA THROUGH TONIGHT. HOWEVER
ALL INGREDIENTS REMAIN IN PLACE FOR CONVECTION AS THE UPPER LOW
REMAINS OFF THE CENTRAL CALIFORNIA COAST WITH A RIDGE CENTERED OVER
EASTERN ARIZONA. THIS IS PROVIDING PLENTY OF MOISTURE...PWAT VALUES
OF 1.5 INCHES OR MORE OVER THE SOUTHERN PORTION OF THE CWA AND -2 TO
-4 LI JUST ABOUT CWA WIDE THIS AFTERNOON. MORNING SOUNDING AT KLAS
ALSO INDICATED CAPE VALUES OF OVER 2000 JOULES/KG WHICH IS QUITE
IMPRESSIVE FOR SOUTHERN NEVADA. WITH THIS SAID...WILL CONTINUE THE
ISOLATED/SCATTERED POPS FOR MUCH OF THE AREA THROUGH THIS EVENING
THEN KEEP ISOLATED ACTIVITY OVER MUCH OF THE REGION OVERNIGHT. BY
TUESDAY THE UPPER LOW OFF THE COAST SLOWLY BEGINS TO SHIFT TO THE
NORTHEAST AND INLAND...RESULTING IN A DRIER FLOW MOVING INTO THE
SOUTHWEST PORTION OF THE CWA. THE BEST DYNAMICS/MOISTURE/
INSTABILITY ARE FOCUSED OVER THE SOUTHERN SIERRA/NORTH CENTRAL
NEVADA MOUNTAINS AND THE EASTERN PORTION OF THE CWA FOR TUESDAY
AFTERNOON AND WILL SHOW THE BEST CHANCE OF CONVECTION IN THESE
AREAS. TEMPERATURES COOLED MUCH MORE OVERNIGHT AND ARE HAVING A
DIFFICULT TIME RECOVERING TODAY...BUT ANY COOLING OF TODAY WILL BE
OVERCOME BY TUESDAY RESULTING IN NEAR NORMAL DAYTIME TEMPERATURES
FOR TUESDAY AND WEDNESDAY.

.LONG TERM...THURSDAY THROUGH SUNDAY...BASED ON MODEL FORECASTS FOR
THIS TIME FRAME...THURSDAY BECOMES AN ATTENTION REFOCUSING DAY. WITH
THE UPPER LOW OFF THE WEST COAST FINALLY FORECAST TO LIFT THROUGH
NORTHERN CALIFORNIA AND WEAKEN...FOCUS CAN SHIFT SOUTHWARD TO A
TROPICAL SYSTEM THAT IS FORECAST TO DEVELOP IN THE TROPICS AND
POTENTIALLY APPROACH THE AREA. THE ECMWF HAS THE CENTER OF THE
SYSTEM 300+ MILES SOUTHEAST OF BAJA THURSDAY AFTERNOON AND TRACKS IT
NORTH DIRECTLY ALONG THE GULF OF CALIFORNIA THROUGH THE WEEKEND. THE
GFS HAS IT 400+ MILES SOUTHWEST...OR FURTHER OUT IN THE OPEN
WATER...BUT ALSO TAKES IT NORTH TOWARDS THE SOUTHERN CALIFORNIA
COAST. EITHER WAY...THIS WOULD BRING AN INCREASE IN MOISTURE TO THE
AREA AND POTENTIALLY THE BEST MONSOON SURGE WE HAVE SEEN SO FAR THIS
SEASON. THE PREVIOUS LONG RANGE FORECASTER BEGAN TO SHOW AN INCREASE
IN PRECIP PROBABILITY FOR NEXT WEEKEND. POPS WERE INCREASED AND
EXPANDED A BIT WITH THIS PACKAGE TO SHOW SOME INCREASE IN CONFIDENCE
THAT SOME TYPE OF REMNANT TROPICAL MOISTURE WILL IMPACT THE AREA BY
THE WEEKEND.
&&

.AVIATION...FOR MCCARRAN...SHOWERS AND THUNDERSTORMS ARE EXPECTED IN
THE LAS VEGAS VALLEY FROM LATE AFTERNOON THROUGH THE EVENING.
ERRATIC AND GUSTY WINDS POSSIBLE WITH LOCALLY HEAVY SHOWERS BRIEFLY
LOWERING CEILINGS/VSBY...OTHERWISE CLOUDS SCT-BKN AOA 12K FEET
THROUGH TONIGHT WITH WINDS TRENDING OUT OF THE SOUTH LESS THAN 10
KTS. THUNDERSTORMS ARE EXPECTED TO FORM AROUND THE KLAS VALLEY AGAIN
AFTER 20Z TUESDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED TO SCATTERED THUNDERSTORMS ARE EXPECTED TO
FORM AGAIN THIS AFTERNOON AND CONTINUE THROUGH THE EVENING HOURS
WITH ISOLATED ACTIVITY CONTINUING OVERNIGHT. THUNDERSTORM COVERAGE
WILL AGAIN INCREASE ON TUESDAY. GUSTY AND ERRATIC WINDS POSSIBLE
WITH ANY STORMS. OUTSIDE OF ANY STORMS...WINDS SHOULD GENERALLY BE
SOUTHEAST TO SOUTH AROUND 10 KTS. SCT-BKN CLOUDS AROUND 10-12K
FEET...BUT WILL LOWER TO AROUND 8K FEET NEAR STORMS.
