AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
235 PM PDT SUN OCT 4 2015

.SYNOPSIS...A STRONG AND COOL EARLY SEASON STORM SYSTEM WILL BRING
WIDESPREAD SHOWERS AND THUNDERSTORMS TO THE REGION THROUGH TUESDAY
AS WELL AS ACCUMULATING HIGH MOUNTAIN SNOWFALL. SOME OF THE STORMS
COULD PRODUCE SMALL HAIL AND HEAVY RAIN. AS THE STORM SYSTEM DEPARTS
TO THE EAST ON TUESDAY...LINGERING SHOWERS WILL SLOWLY DIMINISH WITH
DRY WEATHER RETURNING FOR THE SECOND HALF OF THE WEEK. COOL
TEMPERATURES EARLY IN THE WEEK WILL REBOUND TO NEAR NORMAL THURSDAY
ONWARD. &&

.SHORT TERM...THROUGH TUESDAY NIGHT.

SO FAR THE WEATHER HAS UNFOLDED MUCH AS ANTICIPATED WITH THE
GREATEST CONCENTRATION OF SHOWERS AND THUNDERSTORMS TODAY MAINLY
NORTH AND WEST OF INTERSTATE 15. MOST SIGNIFICANT RAINFALL TODAY HAS
BEEN CONCENTRATED ACROSS NYE AND EASTERN INYO COUNTY AS WELL AS
WESTERN CLARK COUNTY FROM THE SPRING MOUNTAINS WESTWARD.  RAINFALL
IN SOME POCKETS HAS BEEN IMPRESSIVE...WITH HARRIS SPRINGS NEAR MT.
CHARLESTON PICKING UP 1.18 INCHES...AND 0.51 INCHES IN DESERT ROCK.
SOME URBAN FLOODING HAS ALSO BEEN REPORTED IN PAHRUMP WITH HAIL UP
TO PENNY SIZED EARLIER TODAY. GREATEST CONCERNS NOW ARE CONCENTRATED
IN INYO COUNTY WHERE DEATH VALLEY HAS BEEN OBSERVING SOME FLOODING
FROM HEAVY THUNDERSTORM ACTIVITY WHICH CONTINUES AT THIS HOUR. ALL
IN ALL...A VERY ACTIVE AFTERNOON.

IN SHARP CONTRAST AREAS FURTHER EAST HAVE BEEN LARGELY DRY. THE LAS
VEGAS VALLEY HAS REMAINED DRY MOST OF THE DAY WITH THE EXCEPTION OF
A FEW STORMS IN THE FAR WESTERN SUBURBS. AS THE LOW MAKES ITS
APPROACH TONIGHT...ANTICIPATE ADDITIONAL BANDS OF SHOWERS AND
THUNDERSTORMS WILL DEVELOP AND SPREAD EASTWARD. GREATEST CHANCES FOR
SHOWERS AND THUNDERSTORMS IN LAS VEGAS LOOK TO OCCUR BETWEEN
MIDNIGHT TONIGHT AND MIDDAY MONDAY. BE PREPARED FOR WET ROADWAYS IN
THE METRO AREA MONDAY MORNING.

THE OVERALL PHILOSOPHY OF THE FORECAST REMAINS UNCHANGED WITH MOST
AREAS NORTH OF INTERSTATE 40 LIKELY TO RECEIVE MEASURABLE RAINFALL
BY TOMORROW AFTERNOON. STRONG SHEAR IN PLACE ALONG WITH MODEST
INSTABILITY WILL CONTINUE TO FAVOR THE POSSIBILITY OF ISOLATED
STRONG THUNDERSTORMS WHICH MAY PRODUCE HAIL AND LOCALIZED FLASH
FLOODING.  IN THE HIGHER ELEVATIONS...SNOW HAS ALREADY BEGUN TO
ACCUMULATE ABOVE 8500 FEET IN THE SIERRA AND AS THE LOW MOVES CLOSER
TONIGHT...SNOW LEVELS WILL FALL IN THE SPRING MOUNTAINS WITH THE
HIGHER PEAKS OF MT CHARLESTON AREA AND THE SHEEP RANGE PICKING UP
SEVERAL INCHES OF SNOWFALL BY MONDAY AFTERNOON. IMPROVING CONDITIONS
ARE EXPECTED MONDAY NIGHT INTO TUESDAY BUT SOME LINGERING SHOWERS
WILL REMAIN AS THE LOW SLOWLY LIFTS EASTWARD INTO ARIZONA.

.LONG TERM...WEDNESDAY THROUGH SATURDAY (FROM PREVIOUS DISCUSSION).

THE UPPER LEVEL LOW THAT WILL KEEP THE SHORT TERM PERIOD ACTIVE WILL
BE PUSHING SOUTHEAST THROUGH AZ WEDNESDAY BEFORE STALLING OVER
NORTHERN MEXICO/WESTERN TX THURSDAY NIGHT. IN IT'S WAKE A STRONG
RIDGE OF HIGH PRESSURE IS FORECAST TO DEVELOP...BRINGING
DRIER...WARMER...AND CALMER CONDITIONS TO THE REGION. THIS RIDGE IS
EXPECTED TO DOMINATE WELL INTO THE WEEKEND WITH TEMPERATURES RISING
BACK ABOVE NORMAL. WE'LL BE KEEPING AN EYE ON THE UPPER LEVEL LOW AS
MODELS CONTINUE TO HINT THAT AT LEAST SOME OF THE ENERGY MAY
RETROGRADE BACK WEST TOWARDS THE REGION SATURDAY AND SUNDAY...AND
COULD IMPACT THE REGION (AGAIN) BY EARLY NEXT WEEK.
&&

AVIATION...FOR MCCARRAN...WINDS WILL REMAIN FROM THE SOUTHEAST TO
SOUTH BETWEEN 130 AND 180 DEGREES THROUGH THIS EVENING WITH GUSTS TO
25 KTS. THERE IS A SLIGHT POSSIBILITY OF A SHRA OR TSRA AT THE
TERMINAL BUT MOST ACTIVITY WILL REMAIN TO THE WEST EARLY AND IMPACT
THE BEATTY AND DAGGETT CORRIDORS. SHRA SHOULD TRANSITION TO A
STEADIER RAIN WITH POSSIBLE EMBEDDED TSRA BETWEEN 10Z AND 12Z MONDAY
AND LAST UNTIL BETWEEN 19Z AND 22Z MONDAY. DURING THIS PERIOD WILL
BE THE BEST OPPORTUNITY FOR CIGS TO DROP DOWN TO AT LEAST 5K FEET
AND LIKELY LOWER TO AROUND 3K FEET IN STEADIER OR HEAVIER PERIODS OF
RAIN OR ANY TSRA. VSBY WILL ALSO LOWER AT TIMES TO MVFR OR LOWER.
LOCAL MOUNTAIN OBSCURATIONS ARE LIKELY. WINDS WILL MAINLY BE 8 KTS
OR LESS AND TREND TOWARD TYPICAL DIURNAL DIRECTIONS. RAIN AND
ISOLATED TSRA ARE EXPECTED MONDAY IN ALL APPROACH CORRIDORS.
ACTIVITY WILL BECOME MORE SHOWERY IN NATURE BY LATER IN THE
AFTERNOON INTO MONDAY EVENING WITH SHRA REMAINING AROUND THROUGH
TUESDAY AFTERNOON.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...GUSTY AND ERRATIC WINDS ARE POSSIBLE IN AND NEAR ANY
TSRA THROUGH MONDAY EVENING. OTHERWISE GUSTY SOUTHERLY WINDS THROUGH
THIS EVENING UP TO 30 KTS THEN WINDS WILL MAINLY TRANSITION TO
TYPICAL DIURNAL DIRECTIONS AT 12 KTS OR LESS. SHRA AND TSRA WILL BE
AROUND THROUGH MONDAY AFTERNOON THOUGH SOME AREAS WILL TRANSITION TO
A STEADIER PERIOD OF RAIN LATER TONIGHT INTO MONDAY MORNING. CIGS
MAY DROP AS LOW AS 3K-6K FEET AND VSBY MAY DROP TO MVFR OR LOWER IN
ANY STEADIER OR HEAVIER RAIN AND NEAR TSRA. MOUNTAIN OBSCURATIONS
ARE EXPECTED ALONG WITH MECHANICAL TURBULENCE ALOFT DUE TO
INCREASING WINDS WITH HEIGHT THIS EVENING. PRECIPITATION SHOULD
BECOME MORE SHOWERY IN NATURE BY MONDAY EVENING.
