AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
640 PM PDT MON AUG 26 2013

.SYNOPSIS...MOISTURE FROM THE REMNANTS OF IVO WILL CONTINUE TO
RESULT IN SCATTERED SHOWERS AND THUNDERSTORMS THROUGH THE MIDDLE
PART OF THE WEEK. ANOTHER DISTURBANCE IS EXPECTED TO BRING
ADDITIONAL MOISTURE INTO THE REGION LATER IN THE WEEK RESULTING IN A
CONTINUATION OF SCATTERED SHOWERS AND THUNDERSTORMS. TEMPERATURES
ARE EXPECTED TO REMAIN AT TO SLIGHTLY BELOW NORMAL.
&&

.UPDATE...BAND OF SHOWERS STRETCHING ACROSS THE CENTRAL PORTIONS OF
THE FORECAST AREA IS STARTING TO WEAKEN WITH RAIN AMOUNTS GENERALLY
LESS THAN A TENTH OF AN INCH. THERE IS SOME CLEARING MOVING NORTH
ACROSS PORTIONS OF MOHAVE...CLARK AND EASTERN SAN BERNARDINO
COUNTIES AND THIS CLEARING SHOULD MOVE SLOWLY NORTH THIS EVENING. A
FEW STRONG THUNDERSTORMS OVER MOHAVE COUNTY IN AREAS WHERE THE SUN
HAS BEEN OUT LONGER WITH THE MOST CONCENTRATED AREA OVER FAR
NORTHERN MOHAVE COUNTY. THESE STORMS SHOULD GRADUALLY WEAKEN AFTER
SUNSET. MADE A FEW UPDATES TO THE GRIDS.
&&

.SHORT TERM...A BAND OF LIGHT TO MODERATE SHOWERS EXTENDING FROM
SOUTHWEST SAN BERNARDINO COUNTY THROUGH CLARK COUNTY AND INTO
LINCOLN COUNTY. GENERAL RAIN AMOUNTS UP TO A QUARTER OF AN INCH HAVE
BEEN NOTED UNDER THIS BAND. WITHOUT ANY SIGNIFICANT DISTURBANCE
THUNDERSTORMS AND HEAVY RAIN WERE NOT ABLE TO DEVELOP UNDER THIS
BAND. THERE WAS SOME SUN THIS AFTERNOON ACROSS NORTHERN INYO INTO
ESMERALDA COUNTY THIS AFTERNOON...BUT JUST NOT ENOUGH INSTABILITY TO
DEVELOP ANYTHING MORE THAN A FEW CUMULUS. HOWEVER...WITH A LITTLE
MORE SUN AND INSTABILITY OVER MOHAVE COUNTY...A FEW THUNDERSTORMS
WERE ABLE TO DEVELOP OVER THE PAST COUPLE OF HOURS. THESE SHOULD
CONTINUE INTO EARLY THIS EVENING...BUT GRADUALLY DISSIPATE BY LATE
EVENING.

FOR TUESDAY...WE ARE EXPECTING TO SEE MORE SUN IN THE MORNING WHICH
SHOULD DESTABILIZE THE ATMOSPHERE A LITTLE MORE QUICKLY. THIS SHOULD
LEAD TO MORE THUNDERSTORM COVERAGE. WITH PLENTY OF MOISTURE STILL
AVAILABLE...PWATS OVER AN INCH AREAWIDE AND OVER AN INCH AND A HALF
OVER THE SOUTHERN HALF OF THE AREA...FLASH FLOODING WILL AGAIN BE A
CONCERN. HAVE GONE AHEAD AND EXTENDED THE FLASH FLOOD WATCH INTO
TUESDAY EVENING.

.LONG TERM...WEDNESDAY THROUGH SUNDAY...THE 00Z ECMWF AND GFS MODELS
ARE IN GOOD AGREEMENT WITH THE OVERALL PATTERN THROUGH FRIDAY.
LINGERING MOISTURE OVER THE AREA WEDNESDAY WILL FUEL ISOLATED TO
SCATTERED THUNDERSTORMS IN THE AFTERNOON AND EVENING WITH SURFACE
HEATING EXPECTED TO BE THE PRIMARY MECHANISM TO INITIATE CONVECTION.
ATTENTION WILL ALSO BE TURNED TO A FEATURE THAT COMES INTO VIEW
WEDNESDAY...THE REMNANTS OF TROPICAL STORM FERNAND WHICH IS
CURRENTLY MOVING OFF THE GULF OF MEXICO INTO THE COAST OF EAST
CENTRAL MEXICO. THIS SYSTEM WILL TRANSITION INTO AN EASTERLY WAVE
THAT WILL LIFT ACROSS NORTHWEST MEXICO WEDNESDAY THEN UP INTO
SOUTHERN NEVADA THURSDAY AFTERNOON THROUGH FRIDAY WITH AN ADDITIONAL
SHOT OF CONSIDERABLE MOISTURE. THE EASTERLY WAVE SHOULD ALSO PROVIDE
SOME DYNAMIC SUPPORT FOR AN UPSWING IN SHOWERS AND THUNDERSTORMS
LATE THURSDAY THROUGH FRIDAY. THE ECMWF KEEPS THIS MOISTURE IN PLACE
OVER MOST OF THE FORECAST AREA SATURDAY AND SUNDAY WHILE THE GFS
TRIES TO PUSH IT OUT WITH INCREASING SOUTHWEST FLOW FROM A DEEPER
UPPER LOW DROPPING DOWN INTO NORTHERN CALIFORNIA. THE FORECAST LEANS
MORE TOWARD THE ECMWF SOLUTION AND KEEPS 20-40 PERCENT CHANCE OF
THUNDERSTORMS ACROSS MOST OF THE AREA INTO NEXT WEEKEND. MOISTURE
WILL BE ENTRENCHED AND THE GFS HAS A TENDENCY TO SCOUR IT OUT TOO
QUICKLY. TEMPERATURES WERE LOWER SLIGHTLY THURSDAY AND FRIDAY GIVEN
THE EXPECTED MOISTURE INFLUX.

.AVIATION...FOR MCCARRAN...LIGHT RAIN SHOWERS EXPECTED OVER THE AREA
INTO EARLY THIS EVENING WITH MAINLY PARTLY TO MOSTLY CLOUDY SKIES
OVERNIGHT. THUNDERSTORMS ARE EXPECTED TO REMAIN WELL EAST OF THE
AREA TONIGHT AND AFFECT MAINLY THE PEACH SPRINGS AND MORMON MESA
CORRIDORS. CIGS DOWN TO 5-6K FEET AT TIMES THIS EVENING AND MAINLY
ABOVE 10K FEET OVERNIGHT. MORE SCATTERED THUNDERSTORMS ARE EXPECTED
TUESDAY AFTERNOON AS THE AREA IS EXPECTED TO SEE MORE SUN.
THUNDERSTORMS COULD PRODUCE HEAVY RAIN AND GUSTY WINDS OVER 30 KTS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED TO SCATTERED THUNDERSTORMS THIS EVENING OVER
PORTIONS OF MOHAVE COUNT WITH GENERAL LIGHT TO MODERATE SHOWERS OVER
THE REMAINDER OF THE AREA...MAINLY WEST OF INTERSTATE 15. THESE
SHOWERS WILL GRADUALLY DISSIPATE OVERNIGHT. CIGS DOWN TO 5K FEET
FEET UNDER ANY SHOWERS THIS EVENING AND HIGHER MOUNTAIN PEAKS WILL
BE OBSCURED. SOME CLEARING IS EXPECTED OVERNIGHT. WITH MORE SUN
EXPECTED TUESDAY THUNDERSTORMS WILL BE MORE SCATTERED AND PRODUCE
HEAVY RAIN AND GUSTY WINDS UP TO 40 KTS.
