AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
230 PM PDT SUN MAY 21 2006
.SYNOPSIS...AN UNSEASONABLY STRONG PACIFIC STORM WILL SWING THROUGH
SOUTHERN CALIFORNIA AND SOUTHERN NEVADA ON MONDAY. RAIN OVER THE
SOUTHERN SIERRA AND INYO COUNTY MOUNTAINS WILL CHANGE TO SNOW ABOVE
8000 FEET LATE TONIGHT AND MONDAY MORNING. NUMEROUS SHOWERS AND
ISOLATED THUNDERSTORMS WILL OCCUR ACROSS THE MOJAVE DESERT AND
SOUTHERN GREAT BASIN MONDAY. THE STORM WILL QUICKLY MOVE UP THROUGH
UTAH MONDAY NIGHT...WITH DRY WEATHER RETURNING FOR THE REMAINDER OF
THE WEEK.
&&
.SHORT TERM...RECENT SATELLITE IMAGERY SHOWED THE UPPER LOW OFF THE
SOUTHERN CALIFORNIA COAST WAS BECOMING MORE NEGATIVELY TILTED AS
ENERGY ROUNDING THE BASE OF THE SYSTEM EJECTS OUT. INCREASING UPWARD
FORCING IN THE NORTHEAST QUADRANT WAS EVIDENT WITH MORE EXTENSIVE
CLOUD TOP COOLING SEEN ON IR IMAGERY UP THROUGH CENTRAL CALIFORNIA.
DEEPER MOISTURE WITH SCATTERED TO NUMEROUS SHOWERS HAS REMAINED OVER
FAR WESTERN SAN BERNARDINO AND INYO COUNTY AS INDICATED BY THE 12Z
NAM. SURFACE WINDS WERE FINALLY SHOWING A SIGNIFICANT INCREASE
ACROSS THE EASTERN HALF OF THE AREA BUT NOT UP THE OWENS VALLEY OR
ESMERALDA/CENTRAL NYE COUNTIES. WILL PROBABLY CANCEL THE WIND
ADVISORY THERE BUT LEAVE IN EFFECT FOR LINCOLN COUNTY AND THE
COLORADO RIVER VALLEY UNTIL 8 PM. THE MAIN FOCUS FOR OUR AREA WITH
THE INCOMING SYSTEM WILL OCCUR LATE TONIGHT THROUGH MONDAY AFTERNOON
AS THE SYSTEM PICKS UP SPEED AND MOVES INLAND. IT IS WORTH NOTING
THAT THE 18Z NAM IS A LITTLE FASTER THAN THE 12Z RUN. THE NAM SEEMS
TO HAVE HAD A BETTER HANDLE ON THE SYSTEM THAN THE GFS THE PAST 24
HOURS...SO CONFIDENCE IS HIGHER IN THE NAM. THIS WOULD BRING THE
BEST SHOT OF PRECIPITATION ACROSS SOUTHERN NEVADA BETWEEN 12Z AND
18Z MONDAY WITH LINGERING SHOWERS AND THUNDERSTORMS AS THE COLD POOL
SWINGS INTO SOUTHWEST UTAH MONDAY AFTERNOON. INCREASED CHANCES OF
PRECIP INTO THE LIKELY CATEGORY ACROSS MOST OF THE FORECAST AREA
MONDAY. THE SYSTEM QUICKLY PULLS TO THE NORTHEAST MONDAY EVENING AND
LEAVES A SHORTWAVE RIDGE OVER THE REGION BEHIND IT ON TUESDAY FOR
DRY MILD WEATHER WITH TEMPS A LITTLE BELOW SEASONAL NORMALS.
.LONG TERM...MEAN TROUGH REMAINS OFF THE PACIFIC NW COAST THROUGH
FRIDAY WITH THE LOW CENTER MIGRATING FROM A POSITION NEAR 49N/141W
ON WEDNESDAY TO 46N/131W ON FRIDAY. THIS WILL KEEP A DRY SOUTHWEST
FLOW OVER THE REGION AND ABOVE NORMAL TEMPERATURES ARE EXPECTED.
WARM TEMPERATURES CONTINUE UNDER A STRENGTHENING SOUTHWESTERLY FLOW
SATURDAY AS THE LOW MOVES TO OR JUST INLAND NEAR THE CENTRAL OREGON
COASTLINE. THIS POSITION WILL LIKELY CREATE BREEZY CONDITIONS IN
SOME AREAS FRIDAY AFTERNOON. A SHORTWAVE IS FORECAST TO MOVE INTO
NORTHERN CALIFORNIA SATURDAY AND THEN ACROSS NORTHCENTRAL NEVADA
SUNDAY. THIS WOULD ALLOW FOR BREEZY TO WINDY CONDITIONS BOTH
SATURDAY AND SUNDAY. ABOVE NORMAL TEMPS ARE EXPECTED TO CONTINUE
SATURDAY BEFORE COOLING TO NEAR OR POSSIBLY BELOW NORMAL SUNDAY.
MOISTURE AND DYNAMICS ASSOCIATED WITH THE SHORTWAVE IS FORECAST TO
REMAIN NORTH OF CWA AT THIS TIME...SO DRY WEATHER EXPECTED FOR THE
WEEKEND.
&&
.AVIATION...ISOLATED THUNDERSTORMS ARE POSSIBLE ALONG THE SIERRA
CREST AND OWENS VALLEY THROUGH THE REST OF THE AFTERNOON IMPACTING
TWEB ROUTE 427. IN ADDITION...LOWER CEILINGS NEAR 6000 FT AGL LIKELY
IN THIS SAME REGION. ELSEWHERE...ISOLATED THUNDERSTORMS ARE POSSIBLE
WITHIN THE BEATTY CORRIDOR...MAINLY NEAR AND NORTHWEST OF KTPH. IN
ADDITION...SURFACE WIND GUSTS FROM 25 TO 35 KNOTS ARE LIKELY FOR THE
LATE AFTERNOON AND EARLY EVENING ACROSS MUCH OF THE REGION. TAFS AND
TWEBS ADEQUATELY DESCRIBE EXPECTED WEATHER CONDITIONS FOR AREA
TERMINALS. SEE TAFS FOR
KLAS...KVGT...KDRA..KBIH...KDAG...KEED.
AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.
&&
.FIRE WEATHER...WINDS WERE INCREASING ACROSS THE RED FLAG WARNING
AREA EARLY THIS AFTERNOON AND RH VALUES WERE GENERALLY IN THE 10-15
PERCENT RANGE. GUSTS OVER 35 MPH STILL LOOK LIKELY ACROSS MUCH OF
THE AREA FROM MID AFTERNOON THROUGH EARLY EVENING. GUSTY WINDS MAY
CONTINUE A COUPLE HOURS BEYOND 8 PM PDT/MST...HOWEVER RH VALUES
SHOULD PROGRESSIVELY RECOVER ABOVE 15 PERCENT. WILL LEAVE RED FLAG
WARNING IN EFFECT UNTIL 8 PM PDT/MST.
