AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
952 AM PST WED JAN 20 2010

.SYNOPSIS...TWO MORE STORM SYSTEMS WILL BRING HEAVY RAIN TO THE
VALLEYS AND HEAVY SNOW TO THE MOUNTAINS THIS AFTERNOON THROUGH
THURSDAY NIGHT. RIVER FLOODING WILL BE A CONCERN THROUGH FRIDAY.
SHOWERS WILL LINGER THROUGH FRIDAY...THEN THE AREA WILL DRY OUT
BEGINNING SATURDAY.
&&

.UPDATE...THE BANK OF FOG THAT SPREAD SOUTH ACROSS THE LAS VEGAS
VALLEY THIS MORNING WAS JUST ABOUT GONE SO LET THE DENSE FOG
ADVISORY EXPIRE. HIGH LEVEL CLOUDS THOUGH HAVE SPREAD BACK IN FROM
THE WEST AND AS A RESULT I HAVE ADJUSTED THE SKY GRIDS AND SENT
OUT UPDATED ZONES. THE THIRD ROUND OF PRECIPITATION IS DUE IN THIS
AFTERNOON INTO THIS EVENING BEFORE THE BIG EVENT STARTS ON
THURSDAY AND CONTINUES INTO FRIDAY. WE WILL BE LOOKING AT PRODUCTS
FOR THAT TIME FRAME THIS MORNING AND AFTERNOON AND LOOK FOR
UPDATES THEN.
&&

.PREV DISCUSSION... /ISSUED 725 AM PST WED JAN 20 2010/

.AVIATION...FOR MCCARRAN...DENSE FOG THAT HAS DEVELOPED ACROSS THE
VALLEY WILL LIKELY PERSIST UP THROUGH 16Z THIS MORNING...WITH A 30
PERCENT CHANCE OF DENSE FOG LASTING UP UNTIL 17Z. RELATIVELY CLEAR
SKIES WILL THEN BEGIN BURNING OFF THE FOG...LEAVING US A BREAK IN
THE WEATHER TODAY BEFORE THE NEXT SYSTEM BRINGS IN ANOTHER PERIOD OF
RAIN...AT TIMES HEAVY...TO THE LAS VEGAS VALLEY THIS EVENING AND
INTO THURSDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...PATCHES OF FOG AND STRATUS HAVE FORMED IN SEVERAL
VALLEY LOCATIONS AND OTHER SHELTERED AREAS THIS MORNING...IN
PARTICULAR THE OWENS VALLEY AND JUST NORTH OF THE LAS VEGAS VALLEY
ALONG THE US HIGHWAY 95 CORRIDOR. THIS SHOULD BURN OFF QUICKLY THIS
MORNING BEFORE ANOTHER STORM SYSTEM MOVES INTO THE REGION THIS
AFTERNOON AND EVENING. EXPECT WIDESPREAD RAIN AND SNOW THROUGH THE
ENTIRE REGION WITH LOW CEILINGS WEDNESDAY AFTERNOON THROUGH THURSDAY.
&&

.PREV DISCUSSION...FROM 344 AM PST...SATELLITE LOOP LOOKS A LOT LIKE
THIS TIME LAST NIGHT WITH ONE STORM EXITING STAGE RIGHT AND ANOTHER
ENTERING STAGE LEFT. THE INCOMING STORM WILL SPREAD MOUNTAIN SNOW
AND VALLEY RAIN ACROSS THE NORTHERN HALF OF THE CWFA TODAY. UPGRADED
THE WINTER STORM WATCH FOR THE CLARK COUNTY MOUNTAINS TO A
WARNING...AND UPGRADED LINCOLN COUNTY TO A WINTER WEATHER ADVISORY.
LATER TONIGHT...RAIN WILL BREAK OUT OVER THE DESERTS...AND IT COULD
BE LOCALLY HEAVY NEAR AND EAST OF THE COLORADO RIVER.
UNFORTUNATELY...THIS IS ONLY ROUND ONE OF A ONE-TWO PUNCH. BY THE
TIME THE PRECIP ENDS OVER OUR SOUTHEAST ZONES THURSDAY MORNING...THE
NEXT STORM WILL ALREADY BE SLAMMING ONSHORE IN SOUTHERN CALIFORNIA.
MORE PRECIP WILL SPREAD ACROSS OUR AREA DURING THE DAY
THURSDAY...WITH YET MORE HEAVY RAIN POSSIBLE OVER SAN BERNARDINO AND
MOHAVE COUNTIES. THIS STORM WILL ALSO PULL UP MUCH WARMER AIR AHEAD
OF IT...WHICH COULD LEAD TO A RAIN-ON-SNOW SITUATION WHICH WOULD
AGGRAVATE THE FLOODING POTENTIAL. LEFT THE FLOOD WATCHES IN PLACE.
WITH THE MAIN TROUGH AXIS OVERHEAD ON FRIDAY...THE FIRE HOSE WILL BE
GONE...BUT INSTABILITY SHOWERS WILL PERSIST FOR ONE MORE DAY.

.LONG TERM...HAD SOME DISTRACTIONS DUE TO CURRENT WEATHER CONDITIONS
WHEN WORKING THE LONG TERM FORECAST. HOWEVER...MADE SOME CHANGES TO
THE EXTENDED FORECAST BY LOWERING THE POPS THIS WEEKEND...PRIMARILY
IN THE WESTERN PART OF THE FORECAST AREA. THERE WILL STILL BE SOME
PRECIPITATION IN THE EASTERN ZONES UNDER THE MOIST FLOW ON THE BACK
SIDE OF THE DEPARTING STORM FROM THURSDAY AND FRIDAY. WITH THE RIDGE
AXIS BUILDING INTO THE AREA SUNDAY AND MONDAY WE SHOULD SEE SUNSHINE
FOR THE FIRST TIME IN A WHILE SUNDAY BUT DO NOT EXPECT MUCH
TEMPERATURE RISE WITH COOLER AIR TRAPPED IN VALLEYS. THE NEXT SYSTEM
STILL EXPECTED TO START MAKING ITSELF FELT LATE MONDAY AS MOISTURE
GETS DRAWN INTO THE SIERRA FIRST AHEAD OF IT. HAVE GONE AHEAD AND
INCREASED POPS AREAWIDE TUESDAY AS MODELS ARE STAYING CONSISTENT IN
BRINGING A MOIST SYSTEM THROUGH THEN. CONCERN FOR NOW IS THE TREND
TOWARDS A MORE NORTHERLY TRACK WHICH WOULD MAKE THE FORECAST TOO
PESSIMISTIC AND AS THE PREVIOUS DISCUSSION MENTIONED THE POSSIBILITY
OF HIGH SNOW LEVELS AND HENCE RAIN ON SNOWFIELDS LAID DOWN BY THIS
WEEKS STORMS.
&&

.HYDROLOGY...HEAVY RAIN AND POSSIBLY MELTING SNOWPACK THURSDAY COULD
PUSH SOME RIVERS TO OR ABOVE FLOOD STAGE FRIDAY. THE MOST LIKELY IS
THE BIG SANDY RIVER NEAR WIKIEUP...AND THE MUDDY RIVER NEAR GLENDALE
MAY ALSO GET CLOSE BASED ON CBRFC FORECASTS. FLOOD WATCHES REMAIN IN
EFFECT.
&&

.VEF WATCHES/WARNINGS/ADVISORIES...
