AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
950 AM PDT FRI OCT 3 2008

.SYNOPSIS...A SERIES OF UPPER LEVEL DISTURBANCES WILL CROSS THE
GREAT BASIN THROUGH THE WEEKEND. THIS WILL RESULT IN A CHANCE FOR
RAIN AND HIGH ELEVATION SNOW ALONG WITH GUSTY WINDS AND
SIGNIFICANTLY COOLER TEMPERATURES...ESPECIALLY OVER THE WEEKEND.
DRY WEATHER AND A WARMING TREND WILL THEN RETURN FOR THE FIRST HALF
OF NEXT WEEK.
&&

.UPDATE...NEW MODEL DATA GENERALLY AGREES WITH THE GOING FIRST
PERIOD FORECAST SO NO UPDATES PLANNED AT THIS TIME. SATELLITE
IMAGERY SUGGESTS SOME BRIEF CLEARING POSSIBLE ACROSS PORTIONS OF
THE AREA TODAY BUT HIGH LEVEL MOISTURE IS QUICKLY APPROACHING FROM
THE WEST AND SHOULD INCREASE CLOUD COVER AGAIN THIS AFTERNOON FOR
PARTLY TO MOSTLY CLOUDY SKY CONDITIONS. HIGH TEMPS WILL BE TRICKY
AND WILL DEPEND ON THE EXTENT AND DURATION OF ANY CLEARING BUT
GENERALLY EXPECTING 5 OR SO DEGREES COOLER TODAY THAN YESTERDAY.
GUSTY SOUTHERLY WINDS WILL DEVELOP OVER MUCH OF THE AREA TODAY WITH
THE STRONGEST WINDS EXPECTED OVER WESTERN SAN BERNARDINO COUNTY
WHERE GUSTS TO 40 MPH ARE EXPECTED ALONG INTERSTATE 15. ELSEWHERE
GUSTS TO 30 MPH POSSIBLE. STILL LOOKING FOR BREEZY TO WINDY
CONDITIONS ON SATURDAY WITH THE BEST CHANCE FOR SHOWERS IN THE VEGAS
VALLEY SATURDAY AFTERNOON.
&&

.PREVIOUS DISCUSSION...343 AM PDT FRI OCT 3 2008...

.SHORT TERM...NEXT IN THE SERIES OF FAST MOVING DISTURBANCES MOVING
INTO NORTHERN CALIFORNIA/OREGON EARLY THIS MORNING. LIGHT RAIN
SHOWERS ACCOMPANYING THE SYSTEM WHILE FOR THE SOUTHERN GREAT BASIN
AND MOJAVE DESERT SATELLITE SHOWS NEXT WAVE OF HIGH CLOUDS CROSSING
THE REGION. TIME HEIGHTS SECTIONS INDICATE HIGH CLOUDS WILL BE
AROUND ALL DAY WITH CLOUD BASES LOWERING ACROSS THE NORTHWEST ZONES
AS PRECIPITATION INCREASES ACROSS NORTHERN CALIFORNIA AS MAIN UPPER
LOW APPROACHES THE NORTHWEST COAST. OTHER CONCERN FOR THE MOJAVE
DESERT TODAY WILL BE INCREASING SOUTHWEST WINDS WITH GUSTS AROUND 40
MPH IN NORTHWEST SAN BERNARDINO COUNTY. PRECIPITATION WILL SPREAD
SOUTHEAST INTO THE SOUTHERN SIERRA AND CENTRAL NEVADA TONIGHT WITH
MUCH OF OUR BASIN AREA WITHIN THE RAIN SHADOW. RAIN SHOWERS AND HIGH
ELEVATION SNOW SHOWERS WILL INCREASE OVER THE GREAT BASIN SATURDAY
WITH PASSAGE OF TROUGH AXIS. GUIDANCE EVEN STRONGER WITH SOUTHWEST
WINDS SATURDAY IN THE MOJAVE DESERT AND WILL LIKELY NEED A WIND
ADVISORY FOR PARTS OF EASTERN CALIFORNIA...SOUTHERN NEVADA AND
NORTHWEST ARIZONA. TROUGH STAYS PROGRESSIVE MOVING INTO THE FOUR
CORNERS SUNDAY WITH PRECIPITATION ENDING IN THE FAR WEST SATURDAY
EVENING AND TAPERING OFF IN NORTHWEST ARIZONA SUNDAY MORNING. NEAR
TO SLIGHTLY ABOVE NORMAL TEMPERATURES EXPECTED TODAY WITH BIG DROP
OFF SUNDAY FOLLOWING PASSAGE OF COLD FRONT.

.LONG TERM...FOR THE PERIOD BEGINNING MONDAY MORNING...NORTHERLY
FLOW WILL STILL BE IN PLACE ACROSS THE FORECAST AREA AS HIGH
PRESSURE NOSES IN FROM THE WEST IN THE WAKE OF THE WEEKEND LOW
PRESSURE SYSTEM. NORTHERLY GRADIENT BETWEEN ELY AND NEEDLES STILL
ONLY PROGGED TO BE ABOUT 8MB...SO NOTHING MORE THAN LOCALLY BREEZY
CONDITIONS OVER AREAS WHERE NORTH/SOUTH WINDS ARE FAVORED. WESTERLY
FLOW ALOFT WILL THEN PERSIST THROUGH THE WEEK...WHICH WILL KEEP THE
AREA HIGH AND DRY...BRING TEMPERATURES BACK TO ABOVE CLIMO BY
MIDWEEK.MODELS PROG ANOTHER TROUGH OF LOW PRESSURE TO PASS NORTH OF
THE AREA THURSDAY AFTERNOON/EVENING. THIS SYSTEM WILL HAVE LITTLE
IMPACT TO THE REGION IF CURRENT TRACK VERIFIES...BEING WELL TO THE
NORTH. IF IT DOES TREND DEEPER IN NEXT COUPLE MODEL RUNS....WILL
HAVE TO DROP TEMPS AND POSSIBLY INTRODUCE POPS TO NORTHERN ZONES.
&&

.AVIATION...FOR MCCARRAN...SOUTHWEST WINDS WILL INCREASE
TODAY...WITH GUSTS OF 15-25 KTS BY LATE MORNING. THESE WINDS WILL
LIKELY PERSIST THROUGH THE DAY AND NIGHT...THEN INCREASE FURTHER ON
SATURDAY AS A STRONG STORM MOVES INTO THE AREA. GUSTS TO 30KTS OR
MORE WILL BE POSSIBLE WITH A CHANCE OF SHOWERS AND CIGS BELOW 8K FT
MAINLY AFTER 20Z SAT. A FRONTAL PASSAGE WILL OCCUR AROUND 09Z
SUNDAY...WITH NORTH WINDS AND DRIER CONDITIONS EXPECTED BEHIND IT.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...WINDS GENERALLY LESS THAN 10KTS THROUGH 18Z FRIDAY
BEFORE INCREASING WITH GUSTS 20-30KTS EXPECTED ESPECIALLY WESTERN
PORTION OF DAGGETT AND BEATTY CORRIDORS. VARIABLE HIGH LEVEL
MOISTURE OVERNIGHT WITH FEW-SCT CLOUDS NEAR 14K FEET AFTER 18Z
FRIDAY. A STRONG STORM MOVING INTO THE AREA FRIDAY NIGHT AND
SATURDAY TO INCREASED WINDS WITH GUSTS 35-45KTS AND A CHANCE OF
SHOWERS WITH CIGS BELOW 8KFT...MAINLY AFTER 18Z SATURDAY.

VISIBILITIES. A COLD FRONT WILL PUSH SOUTH ACROSS THE AREA SATURDAY
NIGHT WITH NORTH WINDS AND DRIER CONDITIONS EXPECTED ON SUNDAY.

...A SIGNIFICANT CHANGE IN OUR WEATHER WILL OCCUR THIS WEEKEND...

THE FIRST SIGNIFICANT STORM SYSTEM COMING INLAND FROM THE
NORTHEAST PACIFIC WILL BRING A TEMPORARY END TO OUR DRY AND WARM
FALL WEATHER THIS WEEKEND.

RAIN WILL SPREAD SOUTHEAST INTO CENTRAL PORTIONS OF NEVADA AND
INTERIOR SOUTHEASTERN CALIFORNIA TONIGHT. RAIN SHOWERS AND HIGH
ELEVATION SNOW WILL INCREASE ACROSS THE SOUTHERN GREAT BASIN AND
MOJAVE DESERT ON SATURDAY. THE HEAVIEST PRECIPITATION WILL OCCUR
OVER LINCOLN COUNTY LATE SATURDAY AFTERNOON AND EVENING ASSOCIATED

LOWER TO AROUND 8000 FEET FOR A BRIEF PERIOD FOLLOWING THE PASSAGE
OF THE COLD FRONT. RAIN SHOWERS AND HIGH ELEVATION SNOW SHOWERS
WILL END ACROSS MOST OF EASTERN CALIFORNIA AND SOUTHERN NEVADA

AS THE COLD FRONT MOVES INTO CENTRAL NEVADA BY SATURDAY

DESERT AND SOUTHERN GREAT BASIN. WIND GUSTS OF 45 TO 50 MPH ARE
POSSIBLE WHICH WILL CREATE AREAS OF BLOWING DUST AND SAND. A BRIEF
DOWNSLOPE WIND EVENT MAY ALSO OCCUR ALONG THE EAST SLOPE OF THE

56 DEGREES AT THE 7000 FOOT LEVEL ON SATURDAY AND ONLY 52 DEGREES

THOSE WITH ANY OUTDOOR PLANS OR TRAVEL THIS WEEKEND SHOULD PREPARE

ALERT WHILE TRAVELING FOR STRONG CROSSWINDS AS WELL AS SLIPPERY
SPOTS ON ROADS FROM ANY RAIN THAT DOES FALL. IF YOU ARE VENTURING
INTO THE HIGHER ELEVATIONS REMEMBER TO DRESS APPROPRIATELY AS MUCH
COLDER TEMPERATURES ARE EXPECTED.

ON THIS SITUATION.
