AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
235 PM PDT WED JUL 3 2013

.SYNOPSIS...AN EXCESSIVE HEAT WARNING WILL CONTINUE THROUGH
INDEPENDENCE DAY FOR THE INTENSE AND DANGEROUS HEATWAVE ACROSS THE
REGION. ISOLATED AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS
WILL REMAIN POSSIBLE THROUGH SATURDAY BEFORE DRIER CONDITIONS ARRIVE
EARLY NEXT WEEK. GUSTY WINDS AND LIGHTNING WILL BE THE PRIMARY
THREAT WITH THESE STORMS. SLIGHTLY COOLER...BUT STILL ABOVE NORMAL
TEMPERATURES ARE EXPECTED THIS WEEKEND.
&&

.SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT...TEMPERATURES HAVE
BEEN A BIT BEHIND TODAY...BUT ARE STILL EXPECTED TO REACH EXCESSIVE
HEAT LEVELS. THE STRONG HIGH PRESSURE THAT HAS BROUGHT THE EXCESSIVE
HEAT SHOULD BEGIN TO PUSH SOUTH THURSDAY AS A TROUGH APPROACHES THE
WEST COAST. WILL BE LEAVING THE EXCESSIVE HEAT WARNING IN PLACE
THROUGH THE FOURTH OF JULY HOLIDAY AS ONE MORE DAY OF 112+
TEMPERATURES ARE EXPECTED IN LAS VEGAS.

WITH THE SLOWER HEATING TODAY...SHOWERS AND THUNDERSTORMS HAVE ALSO
BEEN SLOW TO DEVELOP AND MAINLY ISOLATED CELLS OVER THE HIGHER
TERRAIN ARE EXPECTED TODAY. CONVECTION SHOULD TAPER OFF AFTER
SUNSET...BUT I DID BOOST POPS SLIGHTLY ACROSS SAN BERNARDINO COUNTY
SINCE WE HAVE SEEN ACTIVITY THERE THE PAST COUPLE NIGHTS. SHORT TERM
MODELS INDICATE AN INCREASE IN ACTIVITY FOR THE FOURTH OF JULY
HOLIDAY...MAINLY NORTH OF LAS VEGAS. ACTIVITY IS EXPECTED TO BEGIN
AS DIURNALLY DRIVEN STORMS MUCH LIKE THE PAST SEVERAL DAYS.
HOWEVER...A WEAK WAVE PASSING TO THE NORTH OF THE AREA COULD ACT TO
ENHANCE AND ORGANIZE SOME OF THE ACTIVITY AS IT PUSHES EAST BETWEEN
21Z THURSDAY AND 06Z FRIDAY. THESE STORMS WILL LIKELY BE A BIT
WETTER THAN THOSE SEEN THE PAST COUPLE DAYS AS PRECIPITABLE WATER
VALUES OF AROUND 1 INCH REACH AS FAR NORTH AS THE LINE FROM DEATH
VALLEY TO ST GEORGE. GUSTY WINDS...BRIEF HEAVY RAIN...AND LIGHTNING
WILL BE THE MAIN CONCERN WITH THESE STORMS. STORM MOTION IS EXPECTED
TO BE GENERALLY WEST TO EAST AT 5 TO 10 MPH...THUS WILL NEED TO
MONITOR FOR NUISANCE FLOODING ISSUES ACROSS THE NORTH.

.LONG TERM...FRIDAY THROUGH WEDNESDAY...FORECAST REMAINS ON TRACK
THAT TEMPERATURES WILL FINALLY DROP BELOW EXCESSIVE HEAT WARNING
CRITERIA ON FRIDAY. HOWEVER...IT WILL STILL BE HOT AS TEMPERATURES
REMAIN 5 OR SO DEGREES ABOVE NORMAL. THE HIGH PRESSURE THAT HAS
BEEN PARKED OVER THE AREA FOR THE PAST WEEK SHIFTS TO THE SOUTHEAST
AS A TROUGH APPROACHES THE COAST. THIS WILL ALLOW FOR INCREASED
WINDS ON FRIDAY ACROSS THE ENTIRE CWA WITH THE STRONGEST WINDS
EXPECTED ACROSS PORTIONS OF THE WESTERN MOJAVE DESERT. ISOLATED
THUNDERSTORMS ARE POSSIBLE FRIDAY THROUGH SATURDAY AS ENOUGH
MID-LEVEL MOISTURE REMAINS IN PLACE FOR STORMS TO DEVELOP ACROSS THE
HIGHER ELEVATIONS BUT NO REAL ACCUMULATIONS EXPECTED.

BOTH THE GFS AND ECMWF INDICATE A WEAK SHORTWAVE MOVING ACROSS THE
AREA ON SUNDAY WHICH COULD ENHANCE DYNAMIC SUPPORT FOR MORE
DEVELOPED STORMS ACROSS THE EASTERN PORTIONS OF THE CWA.
HOWEVER...THE ONLY LIMITING FACTOR WILL BE HOW MUCH DRY AIR BEGINS
TO MOVE INTO THE AREA AS WE TRANSITION TO A MORE SOUTHWESTERLY FLOW.
DECIDED TO LEAVE POPS AS IS FOR SUNDAY UNTIL THE TIMING AND LOCATION
OF THE SHORTWAVE AND THE DRY AIR ARE PINNED DOWN. DRY WESTERLY FLOW
IS FORECAST TO REMAIN OVER THE CWA MONDAY THROUGH WEDNESDAY WHICH
WILL ALLOW TEMPERATURES TO INCH BACK UP A FEW DEGREES BY THE
MIDDLE OF NEXT WEEK.
&&

.AVIATION...FOR MCCARRAN...LIGHT WINDS FAVORING AN EASTERLY
COMPONENT WILL SWITCH TO A SOUTHWESTERLY DIRECTION AND INCREASE TO
10-14 KTS BETWEEN 00Z AND 02Z THIS EVENING. ISOLATED THUNDERSTORMS
WILL AGAIN DEVELOP AROUND THE REGION THROUGH THIS
EVENING...PRIMARILY CONCENTRATED IN THE MORMON MESA APPROACH
CORRIDORS BUT POSSIBLY OVER THE PEACH SPRINGS APPROACH AS WELL AS THE
SURROUNDING CLARK COUNTY MOUNTAINS. CLOUD BASES FROM 12-14K FEET ARE
EXPECTED. LIGHT WINDS FAVORING AN EASTERLY DIRECTION ARE EXPECTED
ONCE AGAIN BY LATE THURSDAY MORNING. WINDS ARE EXPECTED TO INCREASE
FROM THE SOUTHWEST BY LATE AFTERNOON.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED SHOWERS AND THUNDERSTORMS WILL DEVELOP AGAIN
THROUGH THIS EVENING. STORMS TODAY WILL BE CAPABLE OF PRODUCING
GUSTY OUTFLOW WIND TO 50 MPH. CLOUDS DECKS WILL MAINLY BE AOA 14K
FEET BUT WILL BE LOWER IN AREAS WHERE SHOWERS AND STORMS DEVELOP.
LIGHT WINDS FAVORING TYPICAL DIURNAL TRENDS ARE EXPECTED OVERNIGHT
AND THURSDAY MORNING. SOUTHWEST WINDS ARE EXPECTED TO INCREASE
ACROSS MUCH OF THE AREA BY LATE THURSDAY AFTERNOON. SHOWER AND
THUNDERSTORM ACTIVITY IS ALSO EXPECTED TO INCREASE SLIGHTLY
THURSDAY...WITH THE MAJORITY OF THE ACTIVITY TO THE NORTH OF LAS
VEGAS.
&&

.FIRE WEATHER...HOT AND DRY SURFACE CONDITIONS WITH ISOLATED TO
SCATTERED AFTERNOON AND EVENING THUNDERSTORMS WILL CONTINUE INTO
THURSDAY. HOWEVER...MODELS CONTINUE TO INDICATE THAT THE MOISTURE
WILL INCREASE SOMEWHAT THURSDAY. FOR THE REMAINDER OF TODAY...MOST
STORMS WILL CONTINUE TO BE MAINLY DRY WITH LIGHTNING AND GUSTY WINDS
BEING THE PRIMARY CONCERN. THE AREAL EXTENT OF THE DRY LIGHTNING IS
NOT ENOUGH TO WARRANT ANY ADDITIONAL FIRE WEATHER PRODUCTS. ON
THURSDAY A WEAK DISTURBANCE MOVING ACROSS NORTHERN NEVADA MAY BRING
A SLIGHT UPTICK IN THUNDERSTORM ACTIVITY...HOWEVER WITH A BIT MORE
MOISTURE THESE STORMS ARE EXPECTED TO BE A BIT WETTER...THUS WILL
HOLD OFF ON FIRE PRODUCTS FOR THURSDAY AT THIS TIME. A WEAK TROUGH
MOVING INTO THE PACIFIC NORTHWEST WILL SUPPRESS THE RIDGE BY THE END
OF THE WEEK AND INTO THE WEEKEND BRINGING SLIGHTLY COOLER
TEMPERATURES TO THE AREA. THE DIURNAL CYCLE OF THUNDERSTORMS COULD
BRIEFLY DRAW TO A CLOSE EARLY NEXT WEEK AS DRY AND STABLE CONDITIONS
ARE FORECAST.
