AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1009 AM PDT MON OCT 5 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...BUT WITH HIGH PRESSURE BUILDING IN
DURING THE WEEK TEMPERATURES WILL CLIMB TO ABOVE NORMAL READINGS
DURING THE SECOND HALF OF THE WORK WEEK.
&&

.UPDATE...THE LATEST RADAR SHOWED THE MAIN AREA OF FOCUS EXTENDED
FROM LAKE MEAD SOUTH ALONG THE COLORADO RIVER VALLEY TOWARD LAKE
HAVASU WHERE SEVERAL ROUNDS OF SHOWERS AND THUNDERSTORMS WERE
HEADING NORTH. EMBEDDED STRONGER ACTIVITY WAS PRODUCING HAIL UP TO
DIME SIZE AS WELL AS DOWNPOURS THAT TRIGGERED MINOR STREET FLOODING
IN LAKE HAVASU CITY. TRAINING OF STORMS IN THIS AREA COULD ALSO LEAD
TO NEW AREAS OF MINOR FLOODING. THE FLOOD THREAT TODAY WILL MAINLY
BE LIMITED TO MORE ADVISORY TYPE FLOODING AS FAR AS THE AMOUNT OF
WATER SO WE WILL NOT ISSUES A FLASH FLOOD WATCH AT THIS TIME. THAT
SAID, ANY STORMS THAT FORM IN SENSITIVE TERRAIN AREAS OR DUMP VERY
HEAVY RAINFALL WITH RATES EXCEEDING AN INCH PER HOUR WILL BE CAPABLE
OF PRODUCING TRUE FLASH FLOODING CONDITIONS.

THE SEVERE THREAT STILL IS OUT THERE FOR THIS AFTERNOON AND EVENING
WITH STORMS WITH GOOD UNIDIRECTIONAL SHEAR NOTED IN THE OBSERVED
SOUNDING FROM VEGAS THIS MORNING AS WELL AS FORECAST SOUNDINGS. WE
ARE STARTING TO SEE SOME CLEARING IN SOUTHEAST MOHAVE COUNTY WHICH
IS THE AREA MOST AT RISK FOR SEVERE STORMS TODAY PER SPC. GUSTY
WINDS AND/OR LARGE HAIL WILL BE THE MAIN THREATS.

SNOW LEVELS HAVE RISEN BACK ABOVE 9500 FEET AND WILL REMAIN THERE
MUCH OF THE DAY UNLESS WE GET ANY HEAVIER BURSTS OF ACTIVITY. ALL
THE OPERATIONAL MODELS CRANK UP SHOWER ACTIVITY THIS AFTERNOON
ACROSS INYO AND ESMERALDA COUNTY AND MOVE ACTIVITY WEST WHICH WILL
HELP TO UPSLOPE AND THUS MAY RESULT IN MORE EFFICIENT PRECIPITATION
RATES. THIS MAY HELP TO LOCALLY LOWER SNOW LEVELS. THE WINTER
WEATHER ADVISORIES WILL BE LEFT AS IS FOR NOW AS SNOW LEVELS WILL
DROP TONIGHT OVER SOUTHERN NEVADA AS THE CENTER OF THE COLD LOW
PASSES BY TO THE SOUTH.

AT THIS TIME NO CHANGES WILL BE MADE TO THE GRIDS AS THE GENERAL
TRENDS IN THE FORECAST LOOK ON TRACK.

&&

.SHORT TERM...THROUGH WEDNESDAY NIGHT.

THE LOW WILL PROGRESS SLOWLY EAST TODAY SO THE SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO REMAIN THROUGH MUCH OF THE DAY AND
EVENING. MOST LOCATIONS WILL LIKELY SEE BETWEEN A QUARTER AND HALF
AN INCH OF RAIN WITH SOME LOCALIZED AREAS RECEIVING BETWEEN A HALF
AND THREE QUARTERS OF AN INCH. A FEW INCHES OF SNOW WAS REPORTED IN
THE SIERRA WITH UPWARDS OF 4 INCHES AROUND THE 9K FOOT LEVEL. SOME
LIGHT ACCUMULATIONS WERE ALSO NOTED IN THE SPRING MOUNTAINS AT THE
HIGHEST ELEVATIONS. AS THE LOW MOVES CLOSER TO SOUTHERN NEVADA SNOW
LEVELS ARE EXPECTED TO DROP AND LOCATIONS ABOVE 8500 FEET COULD SEE
A FEW INCHES OF SNOW BY THIS AFTERNOON. WILL KEEP THE CURRENT WINTER
WEATHER ADVISORY IN PLACE. THE LOW CENTER IS FORECAST TO TRACK
DIRECTLY OVER SOUTHERN NEVADA OVERNIGHT TONIGHT AND THEN NEARLY
STALL THROUGH TUESDAY AFTERNOON. THIS WILL KEEP AT LEAST SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS GOING THROUGH TUESDAY WITH MOST
OF THE SHOWER ACTIVITY CONFINED TO THE EASTERN HALF OF THE FORECAST
AREA.

THE LOW IS EXPECTED TO FINALLY EJECT EAST TUESDAY NIGHT WITH JUST
SOME ISOLATED SHOWERS TUESDAY NIGHT...BUT DRY CONDITIONS AND WARMER
TEMPERATURES BY WEDNESDAY.

.LONG TERM...THURSDAY THROUGH SUNDAY.

NO SIGNIFICANT CHANGES TO THE LONG TERM FORECAST THIS MORNING. THE
UPPER LEVEL LOW THAT WILL KEEP THE SHORT TERM PERIOD ACTIVE WILL BE
PUSHING SOUTHEAST THROUGH SOUTHERN AZ WEDNESDAY BEFORE STALLING OVER
SOUTHERN NM/AZ BORDER THURSDAY MORNING AND DRIFTING SOUTH. THIS WILL
ALLOW HIGH PRESSURE TO NOSE INTO THE REGION...BRINGING DRIER...
WARMER...AND CALMER CONDITIONS TO THE REGION. HIGH PRESSURE IS
EXPECTED TO DOMINATE WELL INTO THE WEEKEND WITH TEMPERATURES RISING
BACK ABOVE NORMAL (BACK INTO THE LOW-MID 90'S FOR LAS VEGAS).

MODELS CONTINUE TO INDICATE THAT THE SAME UPPER LEVEL LOW WILL
RETROGRADE WEST ACROSS NORTHERN MEXICO AND OVER THE PACIFIC SOUTH OF
SAN DIEGO OVER THE WEEKEND. RUN-TO-RUN AGREEMENT ON JUST WHERE THE
LOW ENDS UP IS VERY POOR AS EXPECTED FOR THIS TYPE OF FEATURE...BUT
IT'S CERTAINLY A POSSIBILITY THAT IT COULD IMPACT THE REGION (AGAIN)
SOMETIME NEXT WEEK.

UPDATED AVIATION SECTION
950 AM PDT MON OCT 5 2015

AVIATION...FOR MCCARRAN...A STRONG LOW PRESSURE CIRCULATION OVER
SOUTHERN CALIFORNIA WILL SLOWLY MOVE TOWARD THE COLORADO RIVER
VALLEY THROUGH TONIGHT. THIS WILL PRODUCE NUMEROUS SHOWERS AND

WILL IMPACT THE KLAS TERMINAL AREA AS WELL AS THE PEACH
SPRINGS...MORMON MESA AND BEATTY CORRIDORS. VSBYS MAY LOWER TO UNDER
6SM AT TIMES. LOCAL MOUNTAIN OBSCURATIONS ARE LIKELY. WINDS WILL
FAVOR A NORTHEAST DIRECTION AROUND 6-7 KTS THIS MORNING AND THEN
