AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
225 PM PDT WED AUG 8 2012
.SYNOPSIS...A STRONG RIDGE OF HIGH PRESSURE WILL REMAIN OVER THE
AREA INTO THE WEEKEND BEFORE SHIFTING TO THE EAST. THIS WILL RESULT
IN NEAR RECORD TEMPERATURES THROUGH THE END OF THE WEEK WITH
CONTINUED ABOVE NORMAL TEMPERATURES INTO EARLY NEXT WEEK. ISOLATED
AFTERNOON AND EVENING THUNDERSTORMS WILL ALSO BE SEEN...MAINLY OVER
THE MOUNTAINS.
&&
.SHORT TERM...TONIGHT THROUGH SATURDAY EVENING...ISOLATED AFTERNOON
CONVECTION SO FAR HAS BEEN CONFINED TO MAINLY LINCOLN AND NORTHERN
MOHAVE COUNTY. ALTHOUGH ADDITIONAL AREAS MAY SEE CONVECTION...
ESPECIALLY THE SOUTHERN SIERRA/CLARK COUNTY MOUNTAINS INTO THE
EVENING...OVERALL ACTIVITY SHOULD DECREASE OVERNIGHT.
RIDGE CENTERED OVER EASTERN UTAH/ARIZONA WILL EXPAND SLIGHTLY
FURTHER WEST ON THURSDAY WITH THE RESULTANT INCREASE IN
HEIGHTS/THICKNESS BEING THE MAIN CONCERN DURING THE SHORT TERM.
ALTHOUGH MOISTURE CAUGHT UNDER THE RIDGE WILL CONTINUE TO KEEP AN
AFTERNOON/EVENING CYCLE OF THUNDERSTORMS GOING THROUGH THE PERIOD
MAINLY OVER THE EASTERN MOUNTAINS...DAYTIME TEMPERATURES WILL
CONTINUE TO BE THE PRIMARY FOCUS OF THE FORECAST.
AT THIS TIME...DAYTIME TEMPERATURES THURSDAY AND FRIDAY WILL BE NEAR
RECORDS IN SOME AREAS...BUT MORE IMPORTANTLY..BE AT OR SLIGHTLY
HIGHER THAN EXCESSIVE HEAT WARNING CRITERIA FOR THE AREA. THUS WILL
CONTINUE TO KEEP THE HEAT WARNING IN EFFECT THROUGH FRIDAY. QUESTION
BECOMES WILL THE TEMPERATURES REMAIN AT WARNING CRITERIA ON
SATURDAY. ALTHOUGH THE CURRENT FORECAST TEMPERATURES IN THIS PACKAGE
WILL BE RIGHT AT THE CRITERIA...WILL NOT EXTEND THE WARNING AT THIS
TIME DUE TO UNCERTAINTY ON IF WE WILL SEE A DEGREE OR TWO OF COOLING
BY THEN.
.LONG TERM...BROAD HIGH PRESSURE WILL BE SLOWLY MIGRATING EAST AT
THE BEGINNING OF THE LONG TERM...ALLOWING HEIGHTS TO SLOWLY FALL
WHICH SHOULD MARK THE BEGINNING OF A GRADUAL COOLING TREND /THOUGH
HIGHS ARE STILL EXPECTED TO REMAIN ABOVE NORMAL/. AS THE HIGH MOVES
EAST...MODELS INDICATE A WEAK SURGE OF MIDLEVEL MONSOONAL MOISTURE
MOVING NORTH INTO THE SOUTHERN AND CENTRAL PORTIONS OF THE CWA
SUNDAY...THEN SPREADING NORTHEAST ACROSS THE REST OF THE AREA
MONDAY. AT THE SAME TIME...A DECENT AREA OF LIFTED INDICES OF -1 TO
-2 SPREAD ACROSS THE AREA DURING THIS TIMEFRAME. AS SUCH...HAVE
INCREASED POPS A BIT ACROSS THE SOUTHERN AND CENTRAL AREAS
SUNDAY...AND ACROSS MOST OF THE CWA MONDAY. INCREASED CLOUD COVER
DURING THIS TIMEFRAME MAY ALSO HELP TO LIMIT HIGH TEMPERATURES.
THE MAJORITY OF MEDIUM RANGE MODELS ARE IN FAIRLY GOOD AGREEMENT
THAT THE HIGH CENTER WILL BE LOCATED OVER WEST CENTRAL NEW MEXICO BY
12Z MONDAY. MODELS THEN BEGIN TO SHOW CONSIDERABLE SPREAD THROUGH
THE REST OF THE LONG TERM. CONSENSUS SHOWS A PATTERN CHANGE DURING
THE MIDDLE OF NEXT WEEK...AS GENERAL TROUGHINESS SETS UP OVER THE
EASTERN PACIFIC OR ALONG THE WEST COAST AND SLOWLY MIGRATES EAST.
HAVE NOT TRIED TO NAIL DOWN ANY DETAILS AT THIS POINT SINCE
RUN-TO-RUN AND MODEL-TO-MODEL DIFFERENCES ARE GREAT...ESPECIALLY
FROM WEDNESDAY ONWARD. IN GENERAL...TEMPERATURES ARE LIKELY TO
CONTINUE TO FALL SLOWLY WHILE DRIER AIR WORKS ITS WAY INTO THE CWA.
&&
.AVIATION...FOR MCCARRAN...FEW-SCT MIDLEVEL CLOUDS AOA 8K FEET ARE
EXPECTED THROUGH SUNSET THIS EVENING. WINDS HAVE BEEN A BIT HIGHER
THIS AFTERNOON THAT INITIALLY FORECAST...HAVE BUMPED UP WINDS
THROUGH 03Z...BUT THIS WILL NEED TO BE WATCHED THROUGH THIS EVENING.
LIGHT...DIURNAL WINDS ARE EXPECTED AGAIN TOMORROW...WITH TEMPS AOA
100F THROUGH 04Z THIS EVENING AND AGAIN FROM 18Z TO 04Z TOMORROW.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED SHRA/TSRA HAVE DEVELOPED AGAIN TODAY...MAINLY
ACROSS THE HIGHER ELEVATIONS OF LINCOLN...CLARK...NYE...AND MOHAVE
COUNTIES. GUSTY AND ERRATIC WINDS ARE POSSIBLE IN AND NEAR ANY
SHRA/TSRA ALONG WITH REDUCED CIGS/VSBY. OTHERWISE...EXPECT WINDS
FAVORING DIURNAL TRENDS WITH FEW-SCT CLOUDS AOA 10K-12K FEET THROUGH
00Z FRIDAY.
