What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Las Vegas, NV wrote its last area forecast discussion before this flash flood warning went out at Jul 19, 10:31 AM PDT, 4 hours 58 minutes earlier.

Area forecast discussion, Jul 19, 10:31 AM PDT, 4 hours 58 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1031 AM PDT SUN JUL 19 2015

.SYNOPSIS...A RICH...MOIST ENVIRONMENT WILL BE IN PLACE ACROSS THE
AREA TODAY AND COMBINE WITH AN UPPER LEVEL DISTURBANCE APPROACHING
FROM THE SOUTH TO CREATE FAVORABLE CONDITIONS FOR FLASH FLOODING. A
FLASH FLOOD WATCH IS IN EFFECT THROUGH THIS EVENING FOR ALL OF THE
FORECAST AREA. MONDAY COULD BRING ANOTHER DAY OF THUNDERSTORMS TO
AREAS MAINLY NORTH OF INTERSTATE 15 BEFORE MOISTURE GRADUALLY
DECREASES AND TEMPERATURES INCREASE THROUGH THE REST OF THE WEEK.
&&

.UPDATE...CURRENTLY A QUIET MORNING ACROSS THE AREA ON RADAR AND
WATER VAPOR IMAGERY CONFIRMS THIS. THE MOST ACTIVE AREA RIGHT NOW
FOR CONVECTION IS ACTUALLY OUTSIDE OF OUR AREA ALONG THE CENTRAL
CALIFORNIA COAST WHERE SHOWERS AND THUNDERSTORMS HAVE FIRED FROM A
MID/UPPER LEVEL DISTURBANCE. THE REMNANT CIRCULATION OF DOLORES IS
TOUGH TO SEE ON WATER VAPOR WITH RESPECT TO ANY WELL-DEFINED
SWIRLING MOTION BUT IS STILL OUT THERE OFF THE BAJA IN THE EASTERN
PACIFIC.

THE MOISTURE PUSHED BY DOLORES STILL REMAINS IN PLACE AND
PRECIPITABLE WATER VALUES AND SURFACE DEWPOINTS ARE STILL SUFFICIENT
ENOUGH TO SUPPORT THE POTENTIAL FOR FLASH FLOODING TODAY IN ANY
STRONGER OR SLOWER MOVING THUNDERSTORM ACTIVITY. WE MAY BE A LITTLE
LIGHT ON POPS IN THE NORTHWEST CWFA FOR THIS AFTERNOON AND EVENING
BUT I WILL SEE HOW THINGS TREND AS THE DAY UNFOLDS. THE CURRENT
FORECAST LOOKS IN GOOD SHAPE AND DOES NOT NEED ANY CHANGES AT THIS
TIME.
&&

.SHORT TERM...THROUGH TUESDAY NIGHT...

MODELS AGREE IN BRINGING THE REMNANT CIRCULATION OF DOLORES NORTH
TODAY TOWARDS SOUTHERN CALIFORNIA AND THEN INTO SOUTHERN CAL AND
ACROSS THE FORECAST AREA TONIGHT. MODEL QPF FORECASTS POINT TO
SCATTERED SHOWER AND THUNDERSTORM ACTIVITY BREAKING OUT ACROSS MUCH
OF THE FORECAST AREA BY THIS AFTERNOON AIDED BY A COMBINATION OF
INCREASING MOISTURE, OROGRAPHIC LIFT, DAYTIME HEATING, WEAK-MODERATE
INSTABILITY AND A LIFTING MECHANISM APPROACHING FROM THE SOUTH LATER
IN THE DAY. AS WE SAW YESTERDAY, ATMOSPHERIC CONDITIONS ARE RIPE FOR
HEAVY RAIN PRODUCING THUNDERSTORMS AND THE POTENTIAL FOR LIFE
THREATENING FLASH FLOODING. THE QUESTION REMAINS WHEN AND WHERE
THESE STORMS WILL DEVELOP. A FLASH FLOOD WATCH IS IN EFFECT TODAY
AND INTO THIS EVENING TO HIGHLIGHT THE THREAT.

MOISTURE REMAINS IN PLACE ON MONDAY WITH WEAK INSTABILITY FORECAST.
THE UPPER LEVEL FLOW TURNS SOUTHWEST AS LOW PRESSURE OFF THE COAST
MOVES INLAND AND THIS COULD RESULT IN INCREASING SHEAR AND THE
POTENTIAL FOR A FEW STRONG THUNDERSTORMS IN ADDITION TO THE
CONTINUED THREAT OF FLASH FLOODING. IT IS POSSIBLE THAT A FLASH
FLOOD WATCH WILL BE NECESSARY ONCE AGAIN FOR PORTIONS OF THE AREA ON
MONDAY. IT LOOKS LIKE THE BEST CHANCE FOR SHOWERS/STORMS WILL BE A
LITTLE FURTHER NORTH ON MONDAY...GENERALLY NORTH OF INTERSTATE 15.
DECREASING MOISTURE IS FORECAST TUESDAY WITH INSTABILITY CONFINED TO
MAINLY THE SIERRA, THE SOUTHERN GREAT BASIN AND THE NORTHERN MOHAVE
COUNTY.

.LONG TERM...WEDNESDAY THROUGH SATURDAY. MODELS STILL AGREE ON
LIFTING THE REMNANT MID LEVEL CIRCULATION OF DOLORES AWAY FROM OUR
AREA BY WEDNESDAY. RUN TO RUN CONSISTENCY IS NOW GOOD ENOUGH TO
JUSTIFY REDUCING POPS FOR THE CENTRAL AND SOUTHERN ZONES ON
WEDNESDAY...LEAVING ONLY A STRIPE OF THUNDERSTORM CHANCES FROM THE
SIERRA NEVADA ACROSS THE HIGHER TERRAIN OF THE SOUTHERN GREAT BASIN.
DRIER SOUTHWEST FLOW IS STILL EXPECTED FOR THURSDAY THROUGH
SATURDAY...SO KEPT THE INHERITED DRY FORECAST. WITH THE
AFOREMENTIONED INCREASED CONFIDENCE IN THE DRYING TREND...ALSO
ACCELERATED THE WARMING TREND IN THE LONG TERM PERIOD...BUT NOT AS
MUCH AS THE ECMWF GUIDANCE SUGGESTS.
&&

.AVIATION...FOR MCCARRAN...LIGHT AND VARIABLE WINDS THIS MORNING
WITH SCT-BKN CLOUDS A0A 14K FEET. SHOWER AND THUNDERSTORM CHANCES
ARE NEARLY ZERO THIS MORNING. SCATTERED SHOWERS OR THUNDERSTORMS
WILL FORM THIS AFTERNOON AND EVENING AND COULD DEVELOP WITHIN THE
VICINITY OF THE TERMINAL. IN ADDITION...ALL APPROACH CORRIDORS WILL
BE SUSCEPTIBLE TO SCATTERED SHOWER AND THUNDERSTORM ACTIVITY THIS
AFTERNOON INTO THIS EVENING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...SCT-BKN CLOUDS GENERALLY ABOVE 10K FEET WITH SCATTERED
SHOWERS AND THUNDERSTORMS AREA WIDE TODAY. GUSTY AND ERRATIC SURFACE
WINDS NEAR THUNDERSTORMS ARE POSSIBLE WITH AREAS OF CONVECTIVE
TURBULENCE.
&&

.SPOTTER INFORMATION STATEMENT...SPOTTER ACTIVATION MAY BE NEEDED
TODAY IN MOHAVE...SAN BERNARDINO...AND CLARK COUNTIES.
OTHERWISE...SPOTTERS ARE ENCOURAGED TO REPORT ANY SIGNIFICANT
WEATHER CONDITIONS ACCORDING TO STANDARD OPERATING PROCEDURES. &&
