AREA FORECAST DISCUSSION UPDATE
NATIONAL WEATHER SERVICE LAS VEGAS NV
908 AM PDT WED MAR 24 2010

.SYNOPSIS...HIGH CLOUDS WILL BEGIN TO INVADE OUR SKIES TODAY AHEAD
OF TWO STORM SYSTEMS WHICH WILL AFFECT THE REGION THROUGH FRIDAY.
THE MAIN EFFECT FROM THESE STORMS WILL BE GUSTY SOUTHWEST WINDS ON
THURSDAY AND THEN GUSTY NORTH WINDS ON FRIDAY. LINCOLN AND NORTHERN
MOHAVE COUNTIES WILL ALSO SEE A SLIGHT CHANCE OF RAIN ON FRIDAY.
QUIET WEATHER WILL RETURN FOR THE WEEKEND WITH TEMPERATURES RISING
BACK ABOVE NORMAL.
&&

.UPDATE...NO UPDATES ARE PLANNED THIS MORNING AS THE CURRENT
FORECAST LOOKS TO BE ON TRACK. WILL NEED TO REEVALUATE THE POTENTIAL
FOR STRONG DOWNSLOPE WINDS LEE OF THE SOUTHERN SIERRA AND SPRING
MOUNTAINS EARLY THURSDAY MORNING...AS WELL AS POSSIBLE WIND ADVISORY
CRITERIA WINDS ACROSS MOHAVE AND SAN BERNARDINO COUNTIES TOMORROW
AFTERNOON. CURRENTLY...RAW MODEL OUTPUT INDICATES THE FUNDAMENTAL
PARAMETERS MAY BE THERE FOR A MODERATE EVENT...HOWEVER...THERE IS
SOME DISAGREEMENT BETWEEN HIGH RESOLUTION CROSS SECTIONS. -KENNEDY-

&&
.PREV DISCUSSION...FROM 330 AM PDT...TODAY THROUGH FRIDAY
NIGHT...PROGRESSIVE LONGWAVE PATTERN...TYPICAL FOR SPRING WILL BE
AFFECTING THE WESTERN STATES DURING THE SHORT TERM. THE GREAT BASIN
WILL LIE UNDER A RIDGE TODAY WHICH WILL TRANSLATE TO LIGHTER WINDS
AND NEAR NORMAL TEMPERATURES. RIDGE IS SHORT-LIVED THOUGH AS FIRST
SHORTWAVE TROUGH MOVES INTO NORTHERN CALIFORNIA/NORTHWEST NEVADA
TONIGHT. THIS TROUGH LOOKS TO BE DRY FOR OUR AREA BUT WILL BRING AN
INCREASE IN WEST WINDS TO THE SOUTHERN SIERRA CREST TONIGHT. AS THIS
WAVE CONTINUES EAST INTO NORTHERN UTAH THURSDAY THE NEXT SHORTWAVE
TROUGH TRACKING ON A SLIGHTLY FURTHER SOUTH TRAJECTORY MOVES INTO
THE CENTRAL SIERRA THURSDAY EVENING. THE TROUGH CONTINUES SOUTHEAST
ACROSS THE SOUTHERN GREAT BASIN AND MOJAVE DESERT FRIDAY. WIND WILL
BE THE MAIN CONCERN FOR ANY HIGHLIGHTS AS ANY PRECIPITATION WILL BE
LIGHT AND CONFINED TO OUR NORTHERN ZONES THURSDAY NIGHT AND EASTERN
ZONES FRIDAY MORNING. THERE WILL BE CONTINUED STRONG WEST WINDS AND
SOME DOWNSLOPE POTENTIAL IN THE LEE OF THE SOUTHERN SIERRA UNTIL
TROUGH PASSAGE FRIDAY MORNING. MODEL GUIDANCE ALSO SHOWS STRONGER
PRE FRONTAL WEST TO SOUTHWEST WINDS ACROSS SAN BERNARDINO AND MOHAVE
COUNTIES ON THURSDAY FOLLOWED BY GUSTY POST FRONTAL NORTHWEST WINDS
ON FRIDAY. WIND ADVISORIES MAY BE REQUIRED.

.LONG TERM...HIGH PRESSURE IS FORECAST TO BE IN CONTROL OVER THE
WEEKEND. NORTH WINDS MAY START OUT A BIT GUSTY SATURDAY MORNING BUT
SHOULD DECREASE THROUGH THE DAY. TEMPERATURES ARE FORECAST TO TOP
OUT AROUND NORMAL SATURDAY BEFORE WARMING SEVERAL DEGREES FOR
SUNDAY. A LONGWAVE TROUGH IS FORECAST TO DEVELOP OVER THE EASTERN
PACIFIC NEXT WEEK. THIS HAS BEEN WELL ADVERTISED BY THE VARIOUS
MODELS FOR SEVERAL DAYS NOW. THE UNCERTAINTY WITH IT BESIDES TIMING
OF INDIVIDUAL SHORTWAVES...IS JUST HOW QUICKLY IT MOVES OUT OF THE
PACIFIC AND INTO THE WESTERN STATES. LATER TUESDAY INTO WEDNESDAY
SEEMS TO BE THE CONSENSUS ALTHOUGH THERE IS STILL CONSIDERABLE
ENSEMBLE SPREAD WITH THE LOCATION OF THE TROUGH AXIS. MONDAY AND
TUESDAY SHOULD STILL BE PLEASANT DAYS WITH TEMPERATURES WELL ABOVE
NORMAL UNDER A DEEP SOUTHWESTERLY FLOW. BEYOND THAT...COOLER
TEMPERATURES WITH BREEZY TO WINDY CONDITIONS AND INCREASED CLOUDS
ARE EXPECTED. PRECIPITATION CHANCES WILL DEPEND ON THE TRACK OF
INDIVIDUAL SHORTWAVE ENERGY BUT TIMING OF ANY ONE FEATURE THIS FAR
OUT IS NEARLY IMPOSSIBLE SO WENT WITH CLIMO AND LEFT IT AT THAT.
DOWNSLOPE WIND STORMS ARE POSSIBLE ALONG THE EASTERN SIERRA SLOPES
AS THE UPPER FLOW ACCELERATES AND BECOMES PERPENDICULAR TO THE
SIERRA MID WEEK.
&&

.AVIATION...FOR MCCARRAN...WINDS GENERALLY BELOW 6KTS THROUGH 12Z
THURSDAY WITH HIGH LEVEL MOISTURE INCREASING AFTER 18Z TODAY.
INCREASING WINDS ARE EXPECTED THURSDAY AFTERNOON THROUGH FRIDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...WINDS GENERALLY LESS THAN 10KTS THROUGH 12Z THURSDAY
EXCEPT LOCAL GUSTY NORTH WINDS ALONG THE COLORADO RIVER VALLEY AFTER
18Z TODAY. CLEAR SKIES ACROSS THE AREA WITH INCREASING HIGH LEVEL
MOISTURE BY 18Z TODAY. STRONGER WINDS ARE ANTICIPATED FOR THURSDAY
AFTERNOON THROUGH FRIDAY WITH LINGERING NORTH WINDS ALONG THE
