AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
835 AM PST SAT JAN 4 2014

.SYNOPSIS...A WEAK DISTURBANCE MOVING THROUGH THE REGION WILL BRING
AN INCREASE IN NORTHERLY WINDS THIS AFTERNOON THROUGH SUNDAY.
COOLER TEMPERATURES WILL ALSO BE FELT SUNDAY ACROSS THE AREA. HIGH
PRESSURE WILL TRAVERSE THE AREA MONDAY INTO TUESDAY FOLLOWED BY A
COUPLE OF UPPER LEVEL DISTURBANCES. THESE DISTURBANCES MAY BRING
SOME SHOWERS TO THE AREA WEDNESDAY THROUGH THURSDAY.
&&

.UPDATE...MADE SOME MINOR ADJUSTMENTS TO WIND FORECAST
TODAY...INCREASING THEM A BIT UP NORTH WHERE THE FRONT HAS ALREADY
PASSED. ALSO DELAYED THE INCREASE IN NORTH WINDS DOWN THE RIVER
TODAY BASED ON LATEST GUIDANCE. STILL LOOKING AT A GOOD POSSIBILITY
OF ISSUING A LAKE WIND OR WIND ADVISORY FOR THE COLORADO RIVER
VALLEY FOR TOMORROW. WILL MAKE THAT CALL WITH THE AFTERNOON FORECAST
PACKAGE.
&&

.AVIATION...FOR MCCARRAN...GENERALLY LIGHT WINDS THROUGH EARLY THIS
AFTERNOON. A COLD FRONT WILL BRING A PUSH OF NORTHEAST WINDS ROUGHLY
AROUND 2 PM TODAY WITH NORTHEAST WINDS 6-10 KTS CONTINUING INTO
TONIGHT. GENERALLY CLEAR SKIES THROUGH TONIGHT.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...NORTH TO NORTHEAST WINDS WILL SPREAD SOUTH ACROSS THE
AREA TODAY AND TONIGHT BEHIND A COLD FRONT WITH SPEEDS MAINLY 5-15
KTS. THE EXCEPTION WILL BE THE COLORADO RIVER VALLEY WHERE WINDS MAY
INCREASE TO AROUND 20-30 KTS BY SUNDAY MORNING. SCT-BKN HIGH CLOUDS
FAR SOUTH TODAY OTHERWISE GENERALLY CLEAR SKIES THROUGH TONIGHT.
&&

.PREV DISCUSSION...
215 AM PST SAT JAN 4 2014

.SHORT TERM...BATCH OF HIGH CLOUDS STILL HANGING ON OVER THE
SOUTHERN THIRD OF THE CWA THIS MORNING AND WILL LIKELY HANG AROUND
THROUGH AT LEAST MID MORNING BEFORE BEING PUSHED SOUTH. A
DISTURBANCE MOVING THROUGH UTAH TODAY WILL HELP PUSH A WEAK COLD
FRONT THROUGH THE CWA TODAY. LOCALLY BREEZY CONDITIONS WILL DEVELOP
BEHIND THE FRONT...BUT THE STRONGEST WINDS ARE EXPECTED TO OCCUR
DOWN THE COLORADO RIVER. AS SURFACE HIGH PRESSURE SETS UP OVER
NORTHERN NEVADA TONIGHT AND SUNDAY THIS WILL INCREASE THE GRADIENT
ACROSS THE SOUTHERN PORTIONS OF THE CWA AND BRING GUSTY NORTH WINDS
DOWN THE COLORADO RIVER VALLEY BEGINNING LATE TONIGHT THROUGH
SUNDAY. WIND SPEEDS APPROACHING 40 MPH WILL BE POSSIBLE AND LAKE
WIND OR GENERAL WIND ADVISORIES MAY BE NEEDED. WILL LET THE DAY
SHIFT TAKE ONE MORE LOOK AND MAKE THE FINAL CALL. TEMPERATURES WILL
REMAIN SEVERAL DEGREES ABOVE NORMAL TODAY...BUT WILL DROP AROUND
7-10 DEGREES ON SUNDAY AS THE COOLER AIR ADVECTS INTO THE REGION.
TEMPERATURES WILL REBOUND A COUPLE OF DEGREES ON MONDAY WHICH WILL
PUT THEM SLIGHTLY ABOVE NORMAL. NO PRECIPITATION IS EXPECTED DURING
THE SHORT TERM.

.LONG TERM...TUESDAY THROUGH FRIDAY...MODEL TO MODEL AND RUN TO RUN
CONTINUITY CONTINUE TO SUFFER. 00Z RUNS AGREE REASONABLY WELL ON A
WEAK LEADING SHORTWAVE TROUGH PASSING THROUGH NEVADA TUESDAY NIGHT
WITH ENOUGH MOISTURE TO JUSTIFY A SLIGHT CHANCE OF SHOWERS OVER THE
MOUNTAINS. AFTER A BRIEF RESPITE WEDNESDAY AND WEDNESDAY NIGHT...THE
NEXT WAVE APPROACHES THE NORTHWEST COAST...AND MODEL AGREEMENT
VANISHES. BY THURSDAY THE ECMWF SHOWS A DEEPENING TROUGH OVER THE
GREAT BASIN...WHILE THE GFS SHOWS IT STILL HANGING BACK OVER THE
PACIFIC NORTHWEST. THERE IS SOME AGREEMENT ON THE WAVE AMPLIFYING AS
IT MOVES THROUGH THE WEST THURSDAY NIGHT AND FRIDAY...WITH TIMING
DIFFERENCES AS NOTED ABOVE...AND ALSO A TREND TOWARD MORE OF A DRY
INSIDE SLIDER AS COMPARED TO THE WETTER AND FARTHER WEST SOLUTIONS
LAST NIGHT. CONFIDENCE IS WAY TOO LOW TO JUMP ONTO ANY ONE SOLUTION.
THEREFORE...MADE ONLY MINOR MODIFICATIONS TO THE PREVIOUS FORECAST.
BOTTOM LINE WILL BE A SLIGHT CHANCE OF RAIN AND SNOW SHOWERS MAINLY
OVER THE MOUNTAINS AS INDIVIDUAL SHORTWAVE TROUGHS PASS
THROUGH...TEMPERATURES PRETTY CLOSE TO NORMAL THROUGH THE
PERIOD...AND A POSSIBILITY OF A NORTH WIND EVENT NEXT WEEKEND IF THE
INSIDE SLIDER SOLUTION VERIFIES...BUT AGAIN CONFIDENCE IS VERY LOW.
