AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
300 PM PST WED JAN 30 2008

.SYNOPSIS...DRY NORTHWEST FLOW OVER THE SOUTHERN GREAT BASIN AND
MOJAVE DESERT TONIGHT AND THURSDAY BEFORE THE NEXT PACIFIC STORM
MOVES ACROSS NORTHERN NEVADA THURSDAY NIGHT WITH ANOTHER STORM
MOVING OVER THE AREA ON THE WEEKEND. THIS UNSETTLED WEATHER
PATTERN WILL CONTINUE TO KEEP COOL TEMPERATURES AND BREEZY TO WINDY
CONDITIONS OVER MUCH OF THE REGION WHILE A CHANCE OF SHOWERS WILL BE
SEEN MAINLY OVER THE MOUNTAINS.
&&

.SHORT TERM...NORTHWEST FLOW ALOFT ALONG WITH SURFACE GRADIENTS
CONTINUING TO KEEP LOCAL GUSTY WINDS ACROSS MUCH OF SOUTHERN NEVADA
AND NORTHWEST ARIZONA THIS AFTERNOON. EXPECT THESE WINDS TO DECREASE
FAIRLY QUICKLY AFTER SUNSET WITH GENERALLY LIGHT FLOW BY THURSDAY
MORNING. DRY NORTHWEST FLOW ALOFT TONIGHT INTO THURSDAY TO GIVE WAY
TO NEXT PACIFIC SHORTWAVE SHIFTING ACROSS NORTHERN NEVADA LATE
THURSDAY AND INTO THE ROCKIES BY FRIDAY. THIS SYSTEM WILL ONCE AGAIN
BRING THE POTENTIAL FOR DOWNSLOPE WINDS ACROSS THE SOUTHERN
SIERRA/OWENS VALLEY THURSDAY NIGHT/FRIDAY MORNING AND WILL ISSUE A
HIGH WIND WATCH FOR THIS AREA. AT THE SAME TIME...MAIN ENERGY FROM
THIS SYSTEM TO BE TO THE NORTH OF THE CWA...BUT ENOUGH DYNAMICS TO
CONTINUE MENTION OF ISOLATED SHOWERS ACROSS THE CENTRAL NEVADA
MOUNTAINS FOR THURSDAY NIGHT INTO FRIDAY. BY FRIDAY AFTERNOON AND
INTO SATURDAY MORNING...DRY NORTHWEST FLOW ALOFT TO RETURN TO THE
AREA...BUT THIS WILL BE SHORT LIVED PER THE LONG TERM DISCUSSION.
UNDER THE UNSETTLED CONDITIONS DAYTIME HIGHS THROUGH THE SHORT TERM
TO REMAIN BELOW NORMAL.

.LONG TERM...BROAD TROUGH OVER THE WESTERN HALF OF THE CONUS
SATURDAY WITH SOME LOWER LEVEL MOISTURE STREAMING ACROSS THE CWA.
NOT MUCH IN THE WAY OF PRECIPITATION...BUT DID CONTINUE WITH THE
SLIGHT CHANCE POPS OVER THE NORTHERN CWA ZONES. BIGGER STORY IS
SUNDAY WITH A STRONGER SYSTEM THAT IS FORECAST TO DROP INTO THE
WESTERN STATES. NEWER RUNS OF THE MODELS NOW ARE STARTING TO TREND
THIS SYSTEM SLOWER AND A LITTLE DEEPER THAN THE PREVIOUS RUN. THE
LOW IS FORECAST TO PUSH ON SHORE NEAR THE OR/WA BORDER AND THEN OPEN
UP AND PUSH SOUTH AND EAST. IT LOOKS LIKE THE TROUGH WILL HANG FAR
ENOUGH OFF SHORE TO HELP DRAW IN ADDITIONAL TROPICAL MOISTURE. RIGHT
NOW WE ARE NOT LOOKING AT A MAJOR PRECIPITATION EVENT...BUT SHOWERS
WILL BE A GOOD POSSIBILITY OVER MUCH OF THE CWA BY SUNDAY AFTERNOON
AND EVENING. HAVE GONE AHEAD AND INCREASED POPS OVER THE CWA INTO
THE CHANCE CATEGORY OVER MOST AREAS. THIS SYSTEM IS NOT AS COLD AS
PREVIOUS SYSTEMS...BUT SNOW LEVELS COULD GET AS LOW AS 4500 FEET BY
SUNDAY NIGHT. SYSTEM QUICKLY MOVES THROUGH MONDAY MORNING WITH A
NORTHERLY FLOW DEVELOPING OVER THE AREA AND BRINGING THE POSSIBILITY
OF GUSTY WINDS MONDAY AFTERNOON INTO TUESDAY MORNING. HIGH PRESSURE
DEVELOPING OVER THE EASTERN PACIFIC WILL BUILD AND HELP KEEP SYSTEMS
TO OUR NORTH THROUGH THURSDAY.
&&

.AVIATION...FOR MCCARRAN...NORTHWEST WINDS GUSTING TO AROUND 25
KNOTS TO CONTINUE UNTIL AROUND 00Z BEFORE DECREASING AND BECOMING
VARIABLE AFTER 04Z TONIGHT. VARIABLE CLOUD COVER BUT GENERALLY SCT
THROUGH 04Z THURSDAY BEFORE CLEAR SKIES OVERNIGHT. WINDS ON THURSDAY
ARE EXPECTED TO BE LIGHT AND VARIABLE.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...LOCAL WIND GUSTS TO NEAR 35KTS ACROSS CALIFORNIA
ROUTES WITH LOCAL GUSTY NORTH WINDS ELSEWHERE THROUGH 00Z...THEN
DECREASING AND BECOMING LESS THAN 15KTS BY 04Z. GENERALLY SCT CLOUD
COVER...EXCEPT BKN DECKS AROUND 8K FT AGL MORMON MESA/PEACH SPRINGS
CORRIDORS THROUGH 02Z WITH ISOLD SHOWERS. IMPROVING CONDITIONS BY
02Z WITH GENERALLY CLEAR SKIES OVERNIGHT. CONDITIONS ARE EXPECTED TO
IMPROVE THURSDAY WITH WINDS GENERALLY UNDER 10 KNOTS ACROSS THE
AREA.
&&

.VEF WATCHES/WARNINGS/ADVISORIES...
NV...NONE.
AZ...NONE.
