AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
858 PM PDT SAT AUG 29 2009

.SYNOPSIS...HIGH PRESSURE WILL WEAKEN TONIGHT AND INTO TOMORROW AS A
LOW PRESSURE SYSTEM MOVES ACROSS THE PACIFIC NORTHWEST...BRINGING
SLIGHTLY COOLER TEMPERATURES AND LOCALLY BREEZY CONDITIONS TO THE
SOUTHERN GREAT BASIN. SUBTROPICAL MOISTURE COULD RETURN TO THE
SOUTHERN PORTION OF THE MOJAVE DESERT BY THE MIDDLE OF THIS WEEK.
&&

.UPDATE...BAND OF HIGH CLOUDS EXITING THE AREA TO THE SOUTHEAST AND
BECOMING LESS THICK AS EXPECTED. SMOKE FROM THE STATION FIRE NORTH
OF LOS ANGELES WORKED UP INTO SAN BERNARDINO AND INYO COUNTY THIS
AFTERNOON AND EVENING AND MAY BE QUITE NOTICEABLE OVER PORTIONS OF
THE FORECAST AREA ON SUNDAY. OTHERWISE THE FORECAST FOR TONIGHT IS
IN GOOD SHAPE AND DO NOT PLAN ANY UPDATES THIS EVENING.
&&

.AVIATION...FOR MCCARRAN...SOUTH TO SOUTHWEST WINDS 5-10KTS
EXCPECTED FOR THE REMAINDER OF TONIGHT. SOUTHWEST WINDS WILL
INCREASE ONCE AGAIN TO 10-20KTS AFTER 16Z SUNDAY WITH GUSTS TO
30KTS. CLOUD COVER WILL CONSIST OF VARYING AMOUNTS OF CIRRUS WITH
POSSIBLE SMOKE FROM THE STATION FIRE JUST NORTH OF LOS ANGELES.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...VARIABLE WINDS UNDER 10KTS EXPECTED THROUGH THE
REMAINDER OF TONIGHT. WINDS WILL INCREASE AGAIN ON SUNDAY WITH MOST
AREAS EXPERIENCING WINDS 12-22KTS FROM THE SOUTHWEST WITH LOCAL
AREAS SEEING WINDS 16-26KTS. CLOUD COVER WILL CONSIST OF VARYING
AMOUNTS OF CIRRUS AND POSSIBLE SMOKE FROM THE STATION FIRE JUST
NORTH OF LOS ANGELES.
&&

.PREVIOUS DISCUSSION...300 PM PDT SAT AUG 29...SHORT TERM...CURRENT
VISIBLE SATELLITE IMAGERY SHOWS SOME HIGH LEVEL CIRRUS CLOUDS
ASSOCIATED WITH THE REMNANTS OF TROPICAL STORM IGNACIO OVER THE
SOUTHERN HALF OF THE FORECAST AREA. A POCKET OF DRY AIR WILL MOVE IN
TO REPLACE IT THIS EVENING AS THE UPPER LEVEL MOISTURE MOVES OFF TO
THE SOUTHEAST. A LOW PRESSURE SYSTEM HAS BEGUN TO MOVE OVER THE
NORTHWESTERN STATES AND WILL CONTINUE SOUTHEASTWARD THROUGH
TOMORROW...LOWERING HEIGHTS ACROSS THE BOARD AND BRINGING LOCALLY
GUSTY AFTERNOON WINDS TO MOST OF THE FORECAST AREA. TEMPERATURES
WILL LOWER SLIGHTLY SUNDAY AND MONDAY...BUT ARE STILL EXPECTED TO
REMAIN ABOVE NORMAL. HIGH PRESSURE IS EXPECTED TO REPOSITION OVER
NEW MEXICO AND ARIZONA ON TUESDAY...POSSIBLY FORCING SOME MONSOONAL
MOISTURE INTO THE SOUTHEASTERN PORTION OF THE FORECAST AREA.

.LONG TERM...HIGH PRESSURE IS FORECAST TO ONCE AGAIN SET UP NEAR THE
4-CORNERS REGION ALLOWING FOR A MORE EAST TO SOUTHEAST FLOW OVER THE
SOUTHERN AND EASTERN HALF OF THE CWA. THIS WILL LIKELY LEAD TO A
MOISTURE INCREASE AND A SLIGHT CHANCE OF THUNDERSTORMS ACROSS
PORTIONS OF MOHAVE AND SOUTHEAST SAN BERNARDINO COUNTIES THROUGH
MUCH OF THE EXTENDED. THERE ARE SOME BIG DIFFERENCES BETWEEN THE
MODELS STARTING 12Z THURSDAY. THE GFS WHICH HAS BEEN ADVERTISING A
DEEP UPPER LOW PUSHING INTO THE PAC NW CONTINUES TO DO SO AND
EVENTUALLY DIGS A DEEPER LOW SOUTH INTO NORTHERN CA BY FRIDAY
AFTERNOON AND CONTINUES TO DROP THE LOW INTO SOUTHERN NV BY SUNDAY
AFTERNOON. THE 12Z ECMWF KEEPS THE FLOW MUCH MORE PROGRESSIVE AND
MUCH FURTHER NORTH AS THE JET NEVER DIVES SOUTH KEEPING THE SOMEWHAT
MOIST AIR OVER THE SOUTHEAST CWA. ALTHOUGH CURRENTLY NOT SEEING ANY
SIGNIFICANT MOISTURE PUSH NORTHWARD DURING THE EXTENDED...WE WILL
HAVE TO WAIT AND SEE IF ANY TROPICAL SYSTEMS PLAY A PART IN THE
FORECAST.

.CLIMATE...RECORD HIGH TEMPERATURES FOR TODAY.
