AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
322 AM PDT SUN APR 1 2012

.SYNOPSIS...A PACIFIC STORM MOVING ACROSS THE AREA WILL BRING GUSTY
NORTH WINDS WITH MUCH COOLER TEMPERATURES TO THE AREA TODAY AS WELL
AS A CHANCE OF PRECIPITATION TO MAINLY THE NORTHERN MOUNTAINS. GUSTY
NORTH WINDS WILL CONTINUE ON MONDAY...ESPECIALLY IN THE COLORADO
RIVER VALLEY. TEMPERATURES WILL BEGIN TO WARM ON MONDAY WITH FURTHER
WARMING INTO MID WEEK. HOWEVER ANOTHER STORM IS EXPECTED TO BRING
INCREASED WINDS TO THE AREA ON WEDNESDAY AND THURSDAY.
&&

.SHORT TERM...TODAY THROUGH TUESDAY NIGHT...THE UPPER LOW WHICH
MOVED INTO CALIFORNIA ON SATURDAY IS SLOWLY PROGRESSING EAST THIS
MORNING. AS OF 09Z SUNDAY...THE TROUGH AXIS IS ROUGHLY OVER THE WEST
COAST WITH THE ASSOCIATED COLD FRONT OVER THE EXTREME NORTHWEST
PORTION OF THE CWA...FROM SOUTH OF BISHOP CALIFORNIA TO NORTH OF
BEATTY AND RACHEL NEVADA. AS THE TROUGH SHIFTS EAST DURING THE
DAY...THE FRONTAL BOUNDARY WILL TRANSITION OVER THE REMAINDER OF THE
CWA AND OUT OF THE AREA BY LATE AFTERNOON/EARLY EVENING. BY MONDAY
MORNING...NORTH FLOW ALOFT IS EXPECTED TO BE OVER THE CWA AS THE
CURRENT SYSTEM SHOULD BE OVER EASTERN UTAH/ARIZONA. SHORT WAVE
RIDGING TO THEN BE OVER THE DISTRICT ON TUESDAY.

THE MAIN IMPACT FROM THE PASSAGE OF THIS SYSTEM WILL CONTINUE TO BE
WINDS TODAY AND MONDAY. GUSTY SOUTHWEST WINDS ARE CONTINUING AHEAD
OF THE FRONT WHILE WINDS TURN TO THE NORTHWEST/NORTH BEHIND THE
SYSTEM WHICH WILL CONTINUE TO KEEP ADVISORY LEVEL WINDS GOING ACROSS
MUCH OF SOUTHERN NEVADA AND WESTERN SAN BERNARDINO COUNTY THROUGH
THIS AFTERNOON. BY THIS EVENING WINDS WILL BE DECREASING...BUT WITH
THE FLOW ALOFT TURNING NORTHERLY ON MONDAY AND SURFACE HIGH BUILDING
TO THE NORTH...NORTH WIND PRONE AREAS WILL CONTINUE TO SEE GUSTY
WINDS. THE MAIN FOCUS OF THESE WINDS LOOK TO BE ALONG THE COLORADO
RIVER VALLEY WITH POTENTIAL GUSTS TO BETWEEN 50 AND 60 MPH OR
GREATER POSSIBLE MONDAY MORNING/EARLY AFTERNOON. WILL ISSUE A HIGH
WIND WATCH FOR THIS AREA WITH THE MORNING PACKAGE. PRESSURE
GRADIENTS/FLOW ALOFT DECREASE MONDAY AFTERNOON/EVENING WITH MUCH
LIGHTER WINDS LOOKED FOR AREAWIDE ON TUESDAY UNDER THE SHORT WAVE
RIDGE.

IN ADDITION TO THE WINDS...LIGHT PRECIPITATION IS EXPECTED TO BE
SEEN ALONG THE FRONTAL BOUNDARY...MAINLY NORTH AND EAST OF THE LAS
VEGAS VALLEY...WITH THE BEST CHANCE BEING OVER CENTRAL NYE COUNTY
THIS MORNING AND THEN LINCOLN COUNTY/NORTHERN MOHAVE COUNTY THIS
AFTERNOON/EVENING. WITH THIS SAID THOUGH...A SECONDARY BAND OF
MOISTURE HAS MOVED ACROSS SAN BERNARDINO COUNTY EARLY THIS MORNING
AND WILL BE BRINGING A SLIGHT CHANCE OF LIGHT SHOWERS TO THE CLARK
COUNTY MOUNTAINS THROUGH AT LEAST EARLY AFTERNOON. THE FRONT AND
THIS SECONDARY BAND MAY COMBINE LATER TODAY TO PRODUCE A LITTLE
HEAVIER PRECIPITATION OVER LINCOLN COUNTY...BUT CONFIDENCE IN THIS
HAPPENING IS LOW...HOWEVER WILL KEEP A CLOSE EYE ON IT.

TEMPERATURES ARE EXPECTED TO DROP 15 TO 20 DEGREES TODAY BEHIND THE
COLD FRONT WITH CURRENT 24 HOURS TEMPERATURE CHANGES SHOWING THIS TO
BE RIGHT ON TRACK. WARMING TO BEGIN ON MONDAY WITH MOST READINGS
BEING NEAR NORMAL BY TUESDAY.

.LONG TERM...WEDNESDAY WILL SEE THE AREA UNDER SOUTHWEST TO WEST
FLOW AS ANOTHER SYSTEM FROM THE COAST MOVES INTO THE AREA AND THE
RIDGE AXIS MOVES EAST. WEDNESDAY WILL SEE THE WARMEST TEMPERATURES
OF THE WEEK UNDER THE DRY SOUTHWEST FLOW. AS THE TROUGH DROPS A
LITTLE SOUTH DURING ITS EASTWARD TREK THE STRONGER JET WINDS WILL
ROUND THE BASE OF THE TROUGH TO BRING AT LEAST BREEZY CONDITIONS AND
POSSIBLY STRONGER WINDS TO THE AREA LATE WEDNESDAY EVENING AND
THURSDAY. HIRES MODELS ARE DEPICTING THE POTENTIAL FOR STRONG WINDS
IN THE SIERRA WEDNESDAY AND THEN THE SPRING MOUNTAINS WEDNESDAY
NIGHT...BUT THE PARAMETERS ARE NOT QUITE THERE FOR A DOWNSLOPE
EVENT.

LIKE THE PREVIOUS SYSTEM FROM THIS WEEKEND NOT MUCH MOISTURE IS
ASSOCIATED WITH THIS SYSTEM. HOWEVER I DID KEEP IN THE LOW VALUE
POPS IN OUR SIERRA AND NORTHERN ZONES FOR THURSDAY AND FRIDAY WHERE
THE BEST CHANCES ARE DUE TO AVAILABLE MOISTURE AND LIFT WILL OCCUR.

TEMPERATURES WILL COOL DOWN THURSDAY IN THE WAKE OF THE FRONT THAT
COMES THROUGH EARLY THURSDAY. FOR NOW THE NORTHWEST POST FRONTAL
WINDS ARE NOT EXPECTED TO BE STRONG EXCEPT IN SOUTHERN SAN
BERNARDINO COUNTY.

THE TROUGH QUICKLY MOVES OUT OF THE AREA FRIDAY AND A SHORTWAVE
RIDGE BUILDS UP QUICKLY FOR NEXT WEEKEND LEADING TO A TEMPERATURE
WARM UP.
&&

.AVIATION...FOR MCCARRAN...THE SOUTHWEST WINDS WILL CONTINUE AND
GRADUALLY VEER TO THE WEST AND THEN SHIFT TO THE NORTHWEST TO NORTH
LATER THIS MORNING DUE TO A FRONTAL PASSAGE. FOR NOW THE BEST
ESTIMATE FOR THE WIND SHIFT AT KLAS IS AROUND 15Z. THIS WILL LIKELY
NEED TIMING ADJUSTMENT LATER. FOR THE REST OF THE DAY AFTER THE
FRONT PASSES EXPECT GUSTY NORTHWEST TO NORTH WINDS THROUGH MONDAY
MORNING. PRECIPITATION AT KLAS IS A VERY LOW PROBABILITY...HOWEVER
THERE WILL BE CLOUD COVER ASSOCIATED WITH THE FRONT FOR A FEW HOURS
AS IT PASSES AND CEILINGS COULD GET DOWN TO NEAR 5000 FEET THIS
MORNING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...A COLD FRONT WILL TRANSVERSE THE AREA THIS MORNING AND
BRING WITH IT A SWITCH FROM THE STRONG AND GUSTY SOUTHWEST WINDS
OVER TO THE NORTHWEST AFTER ITS PASSAGE. A BAND OF LOWER CLOUDS WILL
FOLLOW THE FRONTS PASSAGE AND POSSIBLY BRING CEILINGS BELOW 5000
FEET BRIEFLY. ANY PRECIPITATION ASSOCIATED WITH THE FRONT WILL BE
SPARSE IN COVERAGE AND VERY LIGHT IN INTENSITY. SUNDAY EVENING WILL
SEE THE WINDS SUBSIDE AND BY MONDAY MORNING THE AREA SHOULD BE CLEAR
OF ANY SIGNIFICANT CLOUD COVER AND HAVE LIGHT WINDS...EXCEPT DOWN
THE COLORADO RIVER VALLEY WHERE NORTH GUSTS INTO THE 30 TO 40 KNOT
OR HIGHER RANGE WILL OCCUR IN THE MORNING TO EARLY AFTERNOON.
&&

.FIRE WEATHER...WINDS WILL TURN TO THE NORTH DURING THE DAY AS A
COLD FRONT CROSSES OVER THE DISTRICT. THE MAIN IMPACT OF THESE WINDS
WILL BE FELT ALONG THE COLORADO RIVER VALLEY WHERE GUSTY NORTH WINDS
TO OVER 35 MPH WILL COMBINE WITH AFTERNOON HUMIDITIES OF BETWEEN 10
AND 15 PERCENT AND DRY FUELS TO CREATE THE POTENTIAL FOR CRITICAL
FIRE BEHAVIOR. ON MONDAY THE NORTH WINDS WILL CONTINUE...BUT HAVE
THE POTENTIAL TO BECOME EVEN STRONGER THAN WHAT IS EXPECTED TODAY
WITH GUSTS TO NEAR 60 MPH. THE CURRENT RED FLAG WARNING FOR FIRE
ZONES ARIZONA 101...CALIFORNIA 229 AND NEVADA 466 FOR TODAY HAS BEEN
EXTENDED INTO MONDAY DUE TO THE CONTINUATION OF WINDS/LOW
HUMIDITIES. IMPROVING CONDITIONS ARE EXPECTED MONDAY NIGHT INTO
TUESDAY.
