AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
250 PM PDT MON MAY 23 2011
.SYNOPSIS...A WEAK STORM MOVING ACROSS THE AREA THROUGH EARLY
TUESDAY WILL BRING ISOLATED SHOWERS AND THUNDERSTORMS TO MAINLY
LINCOLN COUNTY...WHILE LOCAL GUSTY WINDS WILL BE SEEN ELSEWHERE
THROUGH THIS EVENING. DRYING WILL BE SEEN ON TUESDAY. HOWEVER
ANOTHER STORM WILL ONCE AGAIN BRING GUSTY WINDS TO MUCH OF THE AREA
ON WEDNESDAY WITH COOLER TEMPERATURES THEN SEEN ON THURSDAY. DRY
WITH NEAR NORMAL TEMPERATURES FRIDAY AND SATURDAY.
&&
.SHORT TERM...TONIGHT THROUGH THURSDAY EVENING...SHORTWAVE TROUGH
MOVING ACROSS CENTRAL CALIFORNIA PROVIDING ENOUGH DYNAMICS TO
PRODUCE ISOLATED SHOWERS/THUNDERSTORMS MAINLY NORTH OF LAS VEGAS.
ALTHOUGH THE MAIN FOCUS THROUGH THE NIGHT WILL BE LINCOLN
COUNTY...SHORTWAVE MOVING ACROSS THE CWA WILL BRING ENOUGH
DYNAMICS/NEAR ZERO LIS TO CONTINUE MENTION OF A SLIGHT CHANCE ACROSS
MUCH OF THE NORTHERN TWO THIRDS OF THE CWA MOUNTAINS THROUGH THE
EVENING HOURS. AS THIS SHORTWAVE CONTINUES TO SHIFT EAST DURING THE
DAY ON TUESDAY...WEAK RIDGE TO BUILD OVER THE AREA FOR GENERALLY DRY
AND WARMER CONDITIONS ACROSS MOST OF THE AREA TUESDAY AFTERNOON.
HOWEVER THE NEXT STORM IS FORECAST TO BE CENTERED OFF THE OREGON
COAST...NEAR 45N/133W...BY 12Z WEDNESDAY. THIS CUT-OFF LOW TO BECOME
NEGATIVE TILTED WITH AXIS PUSHING ACROSS THE SOUTHERN SIERRA BY 00Z
THURSDAY. INCREASED SURFACE PRESSURE GRADIENTS/FLOW ALOFT LOOK
PROMISING FOR A FAIRLY STRONG DOWNSLOPE WIND EVENT AND WILL
ISSUE A HIGH WIND WATCH FOR THE EAST SLOPES AND THE WESTERN
FOOTHILLS OF THE OWENS VALLEY FOR WEDNESDAY AFTERNOON/NIGHT. LOCAL
GUSTY WINDS MAY ALSO DEVELOP ACROSS THE REMAINING PORTIONS OF THE
CWA WITH THE MAIN FOCUS LIKELY BEING WESTERN SAN BERNARDINO COUNTY.
WILL MONITOR THIS FOR NOW...BUT WIND ADVISORIES MAY BE NEEDED IN
LATER PACKAGES. DYNAMICS WITH THIS SYSTEM APPEAR TO BE NORTH OF THE
CWA AND WILL ONLY HAVE GHOST POPS ACROSS THE SOUTHERN SIERRA FOR
WEDNESDAY NIGHT. THE LOW IS EXPECTED TO RAPIDLY SHIFT EAST ON
THURSDAY WITH ZONAL FLOW DEVELOPING ACROSS THE CWA BY EARLY THURSDAY
EVENING. TEMPERATURES WILL BE ON A ROLLER COASTER WITH WARMING UNDER
THE WEAK RIDGE ON TUESDAY AND WEDNESDAY...THEN COOLING ONCE AGAIN ON
THURSDAY AS THE TROUGH MOVES ACROSS THE AREA AND ZONAL FLOW DEVELOPS.
.LONG TERM...THURSDAY NIGHT INTO FRIDAY LOOKS TO FEATURE FAIRLY FLAT
WESTERLY FLOW ACROSS THE REGION AS WE SIT IN BETWEEN AN UPPER RIDGE
CENTERED NEAR THE SOUTHERN TIP OF BAJA CALIFORNIA AND AN UPPER LOW
OFF OF BRITISH COLUMBIA WHICH WILL BECOME THE NEXT FEATURE OF
INTEREST. OVERALL OUTSIDE OF SOME HIGH CLOUDS ACROSS THE NORTHERN
HALF OF OUR AREA IN THIS TIME FRAME WE SHOULD SEE SLIGHTLY ABOVE
NORMAL TEMPS IN THIS TIME FRAME. AS WE MOVE INTO SATURDAY THE UPPER
LOW IS SHOWN TO DIP A LITTLE FURTHER SOUTH WHICH SHOULD INCREASE
SOUTHWEST FLOW ACROSS OUR AREA AND WILL PROBABLY RESULT IN HIGH
LEVEL CLOUDS INCREASING IN COVERAGE ACROSS THE AREA. ALTHOUGH HEIGHT
FALLS TAKE PLACE SATURDAY...TEMPS ALOFT REMAIN AS WARM OR ARE EVEN A
LITTLE WARMER THAN WHAT WE SEE ON FRIDAY...AND MIXING INCREASES...SO
HIGHS ON SATURDAY DO NOT SHOW MUCH OF DROP EXCEPT ACROSS THE
SOUTHERN GREAT BASIN.
AS WE MOVE INTO SUNDAY AND BEYOND SIGNIFICANT MODEL DIFFERENCES TAKE
PLACE WITH THE 12Z ECMWF SHOWING A MUCH DEEPER AND SLOWER TO EJECT
TROUGH WHILE THE 12Z OPERATIONAL GFS IS NOT AS DEEP AND QUICKER TO
EJECT IT. A LOOK AT THE 12Z GFS ENSEMBLES SHOW THE OPERATIONAL RUN
IS MUCH SHALLOWER WITH THE TROUGH THAN MANY OF THE ENSEMBLE MEMBERS.
AS A RESULT...I LEANED TOWARDS A BLEND OF THE TWO SOLUTIONS WHICH
WOULD HAVE THE IDEA OF A TROUGH DIGGING INTO THE SOUTHWEST ON SUNDAY
AND MOVING THROUGH ON MONDAY...BUT DID NOT GO AS COLD AND WET AS THE
ECMWF. I KEPT SOME GHOST POPS IN THE SOUTHERN GREAT BASIN IN THIS
TIME FRAME AS THE LAST FEW TROUGHS HAVE ALL MANAGED TO TOUCH OFF
SHOWERS IN THIS GENERAL AREA WHEN THEY MOVED THROUGH. OVERALL WINDS
SHOULD INCREASE ON SUNDAY AND GUSTY WINDS OF SOME DEGREE MAY LINGER
INTO MONDAY. TEMPS FOR NOW WERE KEPT A FEW DEGREES BELOW
NORMAL...BUT NOT AS COLD AS THE DEEPER SOLUTION WOULD SUPPORT WHICH
WOULD POTENTIALLY DROP HIGHS INTO THE 70S FOR LAS VEGAS BY NEXT
MONDAY. OVERALL WE SHOULD SEE SOME SORT OF INCREASE IN CLOUDS...WIND
AND A DROP IN TEMPS...BUT THE DETAILS REMAIN FUZZY.
&&
.AVIATION...FOR MCCARRAN...SOUTHWEST WINDS AT 8-15 KTS WITH GUSTS TO
AROUND 25 KTS ARE EXPECTED THROUGH MOST OF TONIGHT. BETWEEN 10Z AND
17Z TUESDAY SURFACE PRESSURE GRADIENTS RELAX ENOUGH THAT WINDS LOOK
TO BECOME LIGHT...LIKELY OPENING THE DOOR FOR THEM TO VARY IN
DIRECTION. AS A RESULT...DUE TO LOW CONFIDENCE IN A DIRECTION AT
THIS TIME...I WENT WITH VARIABLE WINDS IN THE TAF. BETWEEN 17Z AND
19Z TUESDAY WINDS SHOULD PICK UP OUT OF THE SOUTHWEST TO
WEST-SOUTHWEST TO 10-14 KTS WITH GUSTS UP TO 24 KTS. A FEW CLOUDS
AOA 10K FEET THROUGH TUESDAY AFTERNOON.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...OVERALL WINDS SHOULD REMAIN GUSTY UNTIL BETWEEN 06Z AND
12Z TONIGHT WHEN GRADIENTS DROP OFF ENOUGH TO ALLOW WINDS TO LESSEN
IN MOST AREAS EXCEPT KDAG. BETWEEN 17Z AND 20Z TUESDAY WINDS SHOULD
PICK UP AGAIN FROM THE SOUTHWEST TO WEST IN THE MOJAVE DESERT AND
THE NORTHWEST TO NORTH OVER THE SOUTHERN GREAT BASIN. PEAK GUSTS OF
25-35 KTS ARE EXPECTED THIS EVENING AND 20-28 KTS ON TUESDAY IN THE
LATE MORNING AND AFTERNOON. LOCAL AREAS OF BLDU MAY OCCUR NEAR
STRONGER WINDS. SOUTH OF A KBYS-KVGT-KIGM LINE IT SHOULD REMAIN DRY
WITH A FEW CLOUDS AOA 10K FEET. NORTH OF THIS LINE...SCT SHOWERS AND
ISOLATED THUNDERSTORMS WILL BE AROUND TONIGHT AND TO A LESSER EXTENT
TOMORROW. COVERAGE ON TUESDAY SHOULD MAINLY BE OVER LINCOLN COUNTY.
SCT-BKN CLOUDS AOA 6K-10K FEET IN THE SOUTHERN GREAT BASIN WITH
GUSTY AND ERRATIC WINDS IN AND NEAR SHOWERS AND THUNDERSTORMS.
