AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
322 AM PDT SAT APR 6 2013

.SYNOPSIS...DRY CONDITIONS WITH TEMPERATURES REMAINING ABOVE NORMAL
WILL BE SEEN THROUGH SUNDAY. HOWEVER WINDS WILL BEGIN TO INCREASE
ACROSS MUCH OF THE AREA LATE SUNDAY AHEAD OF A COLD PACIFIC STORM.
THIS STORM WILL MOVE OVER THE REGION SUNDAY NIGHT THROUGH MONDAY
NIGHT...RESULTING IN WIDESPREAD STRONG WINDS...COOLER TEMPERATURES
AND THE POTENTIAL FOR SHOWERS...ESPECIALLY OVER THE SOUTHERN GREAT
BASIN. GUSTY WINDS AND COOL CONDITIONS ARE EXPECTED TO CONTINUE ON
TUESDAY.
&&

.SHORT TERM...TODAY THROUGH MONDAY NIGHT...WEST TO NORTHWEST FLOW
ALOFT OVER THE CWA TODAY WITH MAINLY HIGH LEVEL MOISTURE CAUGHT IN
THE FLOW. HOWEVER THE MAIN CLOUDINESS WILL BE OVER THE NORTHERN
PORTION OF THE CWA AS A WEAK TROUGH PUSHES ACROSS THE PACNW. THE
FLOW ALOFT WILL CONTINUE INTO SUNDAY BEFORE A STRONG TROUGH DEVELOPS
AND DROPS SOUTH ACROSS THE SOUTHERN GREAT BASIN LATE SUNDAY NIGHT
THROUGH MONDAY NIGHT. DIFFERENCES IN TIMING/INTENSITY CONTINUE
BETWEEN THE MODELS...BUT OVERALL...THE TROUGH IS EXPECTED TO BE OVER
THE AREA BY 12Z MONDAY WITH THE CENTER OF THE LOW NEAR SOUTHWEST
UTAH BY 00Z MONDAY BEFORE SHIFTING TO NEAR THE 4-CORNERS REGION BY
12Z TUESDAY.

THE MAIN IMPACT FROM THIS SYSTEM WILL BE WINDS. LOCAL GUSTY WINDS
WILL BE SEEN TODAY ACROSS THE WESTERN MOJAVE DESERT REGION. AS THE
TROUGH BEGINS TO DROP SOUTH AND INTO THE AREA ON SUNDAY...INCREASED
WINDS WILL BE SEEN AREAWIDE. BY SUNDAY AFTERNOON THE WESTERN MOJAVE
DESERT MAY NEED A WIND ADVISORY FOR GUSTS TO OVER 40 MPH...BUT THE
STRONGEST WINDS LOOK TO BE OVER THE SOUTHERN SIERRA/WESTERN OWENS
VALLEY WHERE DOWNSLOPE WINDS ARE POSSIBLE THROUGH SUNDAY NIGHT. WILL
ISSUE A HIGH WIND WATCH FOR THIS AREA WITH THIS PACKAGE. THE
ASSOCIATED COLD FRONT WILL BE MOVING ACROSS THE CWA SUNDAY NIGHT
INTO MONDAY WITH LOCALLY STRONG SOUTHWEST WINDS POSSIBLE AHEAD OF
THE FRONT...BUT STRONG AND GUSTY NORTH WINDS ARE LIKELY BEHIND THE
FRONT. CURRENT MODEL RUNS ARE SHOWING 12-15MB PRESSURE DIFFERENCES
EARLY MONDAY MORNING BETWEEN RENO AND LAS VEGAS...WHILE THE THERMAL
DIFFERENCES AT 700MB IS SHOWN TO BE AROUND 12 DEGREES. A LOCAL WIND
STUDY SHOWS THAT WITH THESE CONDITIONS...WINDS WILL GUSTS TO BETWEEN
50 AND 60 MPH OVER THE LAS VEGAS VALLEY. IF THE NEXT MODEL RUNS ARE
CONSISTENT AND CONTINUE TO SHOW THESE CONDITIONS... WIDESPREAD WIND
ADVISORIES MAY BE NEEDED FOR LATE SUNDAY NIGHT INTO MONDAY EVENING
ACROSS MUCH OF THE CWA.

INCREASE OVER THE NORTHERN MOUNTAINS SUNDAY EVENING AND THEN SPREAD
OVER MAINLY THE EASTERN PORTION OF THE CWA...LINCOLN AND MOHAVE
COUNTIES..ON MONDAY BEFORE DRYING BEGINS TO TAKE PLACE MONDAY NIGHT.

TEMPERATURES FOR THE WEEKEND WILL CONTINUE TO BE WELL ABOVE NORMAL
UNDER THE WESTERLY FLOW ALOFT...BUT WITH THE COLD FRONT MOVING
ACROSS THE REGION LATE SUNDAY/EARLY MONDAY...LOOK FOR MONDAY HIGH
TEMPERATURES DROPPING 15 DEGREES OR MORE ACROSS THE FORECAST AREA.

.LONG TERM...TUESDAY THROUGH FRIDAY...A STRONG NORTH-SOUTH SURFACE
PRESSURE GRADIENT WILL BE IN PLACE TUESDAY AS HIGH PRESSURE BEGINS
TO BUILD BACK IN BEHIND THE COLD FRONT WHICH SWEPT OVER THE AREA ON
MONDAY. LATEST GUIDANCE DOES NOT SHOW THE BEST AGREEMENT REGARDING
THE STRENGTH OF NORTHERLY WINDS ON TUESDAY...BUT BASED ON AN AVERAGE
FORECAST GRADIENT BETWEEN LAS VEGAS AND RENO OF AROUND 15MB STILL IN
PLACE...ADVISORY LEVEL WINDS STILL LOOK LIKE A SAFE BET AT THE
MOMENT...ESPECIALLY DOWN THE COLORADO RIVER VALLEY. MAIN CHANGES TO
THE EXTENDED INCLUDED INCREASING WINDS AND DECREASING
TEMPERATURES...OPTING TO A LITTLE MORE WEIGHT ON THE MEL.

DRY NORTHWEST FLOW WILL SET UP OVER THE AREA ON THURSDAY AND REMAIN
IN PLACE THE REMAINDER OF THE PERIOD...WITH WARMER CONDITIONS
LIGHTER WINDS THURSDAY AND FRIDAY AS HIGH PRESSURE CONTINUES TO
NUDGE INTO THE WEST COAST.
&&

.AVIATION...FOR MCCARRAN...RELATIVELY LIGHT WINDS PRIMARILY OUT OF

UPPER LEVEL CLOUD COVERAGE. A STRONG LOW PRESSURE SYSTEM WILL THEN
IMPACT KLAS STARTING LATE SUNDAY...WITH WINDS INITIALLY INCREASING
OUT OF THE SOUTHWEST AND THEN BECOMING NORTHERLY FOLLOWING FRONTAL
PASSAGE EARLY MONDAY MORNING. WIND GUSTS IN EXCESS OF 40KTS WILL BE
POSSIBLE.
&&

CALIFORNIA...WEST TO NORTHWEST WINDS UP TO 15 KTS AND FEW-SCT CLOUDS
AOA 12K FEET WITH SCT-BKN CLOUDS AOA 20K FEET CAN BE EXPECTED TODAY.
