AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
204 PM PDT WED SEP 11 2013

.SYNOPSIS...A LOW PRESSURE SYSTEM OVER NEVADA WILL CONTINUE TO BRING
SCATTERED SHOWERS AND THUNDERSTORMS TO PORTIONS OF THE REGION
THROUGH FRIDAY WITH THE MOST FAVORED AREAS BEING NORTHERN MOHAVE...
EASTERN CLARK AND LINCOLN COUNTIES. DRYING FROM THE WEST AND SOUTH
IS EXPECTED BY THE WEEKEND AS THE LOW MOVES OUT OF THE DISTRICT.
TEMPERATURES WILL WARM TO ABOVE NORMAL THIS WEEKEND.
&&

.SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT...THE UPPER LOW WHICH IS
CURRENTLY CENTERED OVER NORTHEAST CLARK COUNTY WILL CONTINUE TO
SLOWLY MOVE TO THE NORTH TONIGHT INTO FRIDAY. AS THIS LOW SHIFTS
NORTH...DRYING WILL BE TAKING PLACE ACROSS THE AREA. HOWEVER...UNTIL
THEN...CONSIDERABLE MOISTURE/INSTABILITY TO REMAIN OVER MAINLY THE
EASTERN PORTION OF THE CWA RESULTING IN SCATTERED SHOWERS/
THUNDERSTORMS.

FOR THE REMAINDER OF THIS AFTERNOON...THE CLOUD COVER OF THIS
MORNING HAS HAMPERED SHOWER/THUNDERSTORM DEVELOPMENT ACROSS THE
WESTERN PORTION OF CLARK/EASTERN SAN BERNARDINO COUNTY. HOWEVER WITH
ACTIVITY ROTATING AROUND THE LOW CENTER...IT IS STILL NOT OUT OF THE
QUESTION THAT SHOWERS WILL MOVE INTO THESE AREAS THIS EVENING. HAVE
LOWERED POPS CONSIDERABLY HOWEVER FOR TONIGHT TO THE WEST OF THE
KLAS VALLEY. AS THE LOW SHIFTS NORTH ON THURSDAY...THE MOST FAVORED
AREA FOR SHOWERS/THUNDERSTORMS WILL SHIFT FURTHER NORTH TOO WITH
LINCOLN/NORTHERN MOHAVE COUNTIES BEING THE PRIMARY SPOTS. FURTHER
SHIFTING OF THE LOW ON FRIDAY WILL CONTINUE TO BRING DRYING TO THE
WEST/SOUTH WITH THE PRIMARY AREA FOR ACTIVITY BEING NORTHERN LINCOLN
COUNTY.

RESULTANT DECREASE IN CLOUDS...ESPECIALLY OVER THE EASTERN
PORTION...DAYTIME TEMPERATURES WILL BE WARMING TO NEAR NORMAL BY
FRIDAY.

.LONG TERM...SATURDAY THROUGH WEDNESDAY...HIGH PRESSURE OFF THE
SOUTHERN CALIFORNIA COAST WILL START TO EXPAND NORTHWARD AHEAD OF AN
AREA OF LOW PRESSURE APPROACHING THE NORTHERN CALIFORNIA COAST. SOME
MOISTURE IS STILL EXPECTED TO REMAIN IN PLACE THROUGH SATURDAY...BUT
THE ATMOSPHERE IS FORECAST TO BECOME MORE STABLE UNDERNEATH THE HIGH
AND THE CHANCES FOR ANY PRECIPITATION SHOULD BE MAINLY CONFINED TO
THE FAR EASTERN AREAS OF THE CWA. HOWEVER...THE REAL DRYING TREND IS
EXPECTED TO START SUNDAY AS THE SOUTHWEST FLOW STARTS TO INCREASE
AHEAD OF THE AFOREMENTIONED LOW. THIS SOUTHWEST FLOW WILL BRING IN
MUCH DRIER CONDITIONS ENDING ANY CHANCES OF PRECIPITATION ACROSS THE
ENTIRE CWA. TEMPERATURES WILL ALSO START TO RISE AND ITS POSSIBLE
THAT LAS VEGAS MAY REACH 100 DEGREES ON SUNDAY AND MONDAY. BREEZY TO
WINDY CONDITIONS WILL ALSO BE SEEN TUESDAY AND WEDNESDAY BEFORE A
WEAK COLD FRONT MOVES THROUGH THE AREA WEDNESDAY NIGHT BRINGING
LIGHTER WINDS AND COOLER TEMPERATURES WITH READINGS FALLING TO NEAR
TO SLIGHTLY BELOW NORMAL BY THURSDAY.
&&

.AVIATION...FOR MCCARRAN...SCT-BKN CLOUDS FROM 10-12K FEET WITH BKN
CLOUDS AOA 15K FEET. A FEW SHOWERS MAY MOVE INTO THE VALLEY FROM THE
NORTH OVERNIGHT AND WILL NEED TO BE MONITORED. WINDS SHOULD BE
PRIMARILY LIGHT UNDER 8 KTS WITH DIRECTIONS GENERALLY BEING EASTERLY
THROUGH THIS EVENING BEFORE TURNING MORE SOUTHERLY OVERNIGHT. DRYING
TO TAKE PLACE ON THURSDAY...BUT A CHANCE OF SHOWERS/THUNDERSTORMS
WILL CONTINUE TO BE SEEN OVER THE NEARBY MOUNTAINS AND ESPECIALLY
