AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
828 PM PDT MON APR 29 2013

.SYNOPSIS...A DRY NORTHWEST FLOW ALOFT WILL PERSIST OVER THE AREA
THROUGH THE WEEK. SOUTHWEST SURFACE WINDS WILL PICK UP TUESDAY AHEAD
OF AN APPROACHING COLD FRONT WHILE TEMPERATURES REMAIN ABOVE NORMAL.
BREEZY NORTH WINDS WILL FOLLOW BEHIND THE COLD FRONT TUESDAY NIGHT
THROUGH WEDNESDAY...USHERING IN MUCH COOLER AIR. TEMPERATURES WILL
BE CLOSE TO NORMAL WEDNESDAY AND THURSDAY BEFORE A WARMING TREND
TAKES PLACE FOR THE END OF THE WEEK.
&&

.UPDATE...SATELLITE LOOP SHOWED HIGH CLOUDS COMING IN FROM THE NORTH
WERE HOLDING TOGETHER PRETTY WELL. RAISED SKY COVER OVERNIGHT AND IN
THE MORNING. NO OTHER CHANGES AT THIS TIME.
&&

.PREV DISCUSSION...
321 PM PDT MON APR 29 2013

.SHORT TERM...SOME INCREASE IN HIGH CLOUDS WILL BE SEEN TONIGHT
AHEAD OF A TROUGH AND COLD FRONT APPROACHING FROM THE NORTH.
INCREASING WINDS ARE EXPECTED TUESDAY AS THE FRONT MOVES INTO THE
NORTHERN PART OF THE FORECAST AREA. MODELS ARE INDICATING PRETTY
STRONG SOUTHWEST WINDS ACROSS MUCH OF MOHAVE COUNTY TUESDAY
AFTERNOON AND I HAVE DECIDED TO ISSUE A WIND ADVISORY FOR GUSTS OVER
40 MPH. WINDS WILL BE LIGHTER ELSEWHERE BUT STRONGER THAN WE HAVE
SEEN THE PAST FEW DAYS. NORTHERLY WINDS WILL START TO WORK IN BEHIND
THE FRONT...COOLING TEMPERATURES A BIT ACROSS THE NORTHERN PART OF
THE FORECAST AREA. THE REST OF THE AREA WILL STILL SEE TEMPERATURES
WELL ABOVE NORMAL. MOISTURE IS LIMITED WITH THIS SYSTEM AND
PRECIPITATION IS NOT EXPECTED. HOWEVER...A BAND OF CUMULUS IS LIKELY
TO DEVELOP ACROSS PORTIONS OF LINCOLN COUNTY TUESDAY RIGHT ALONG THE
FRONT AND VIRGA IS A POSSIBILITY. THE COLD FRONT WILL MOVE SOUTH
ACROSS THE REMAINDER OF THE FORECAST AREA TUESDAY NIGHT AND NORTH
WINDS WILL BE LOCALLY BREEZY. THESE BREEZY NORTH WINDS WILL CONTINUE
WEDNESDAY AND WILL INCREASE IN A FEW AREAS...ESPECIALLY DOWN THE
COLORADO RIVER VALLEY. ONCE AGAIN THE MOS NUMERICAL GUIDANCE LOOKS
TOO STRONG WITH WIND SPEEDS AT NEEDLES AND BULLHEAD CITY BUT THERE
IS POTENTIAL THAT A WIND ADVISORY OR AT LEAST A LAKE WIND ADVISORY
WILL BE NEEDED WEDNESDAY. TEMPERATURES BEHIND THE FRONT ON WEDNESDAY
WILL BE 10-15 DEGREES COOLER IN MOST AREAS. THE WINDS ALOFT AND
SURFACE GRADIENT WILL DECREASE THURSDAY RESULTING IN LIGHTER WINDS
ALTHOUGH THE RIVER VALLEY MAY STILL BE A BIT BREEZY. TEMPERATURES
THURSDAY WILL BEGIN TO REBOUND A LITTLE IN MOST AREAS.

.LONG TERM...FRIDAY THROUGH MONDAY...DRY NORTHERLY FLOW WILL REMAIN
OVER THE AREA FRIDAY WITH GENERALLY LIGHT WINDS AND TEMPERATURES
JUMPING ABOUT 5 DEGREES FROM THURSDAYS READINGS. THE MODELS ARE
COMING INTO BETTER AGREEMENT WITH REGARDS TO A TROUGH DROPPING SOUTH
OUT OF WESTERN CANADA AND EVENTUALLY FORMING A CLOSED LOW OVER
CENTRAL CALIFORNIA. INITIALLY THIS TROUGH DOES NOT HAVE MUCH LOW
LEVEL MOISTURE ASSOCIATED WITH IT...BUT PLENTY OF MID AND UPPER
LEVEL MOISTURE. ITS POSSIBLE THAT THERE COULD BE ENOUGH INSTABILITY
OVER THE HIGHER PEAKS OF THE SIERRA TO GENERATE A SHOWER OR
THUNDERSTORM ON SATURDAY AND SUNDAY. RIGHT NOW HAVE HANDLED IT WITH
GHOST POPS...BUT IF THE MODELS REMAIN CONSISTENT CAN EASILY SEE
THOSE NUMBERS BEING RAISED. MODELS ONCE AGAIN BEGIN TO DIFFER BY
MONDAY AS THE GFS KEEPS THE LOW IN PLACE WHILE THE ECMWF PUSHES IT
PRETTY QUICK EAST. THE GFS IS SHOWING PLENTY OF LOW LEVEL MOISTURE
BEING PULLED NORTHWARD MONDAY AND TUESDAY WITH INCREASING
INSTABILITY OVER THE SOUTHERN PORTIONS OF THE CWA. THIS SCENARIO
WOULD POTENTIALLY LEAD TO ISOLATED SHOWERS/THUNDERSTORMS. FOR NOW
HAVE ELECTED TO KEEP THE FORECAST DRY WITH JUST AN INCREASE IN
CLOUDS. TEMPERATURES WILL REMAIN A FEW DEGREES ABOVE NORMAL THROUGH
THE PERIOD...BUT IF THE GFS VERIFIES THEN THOSE NUMBERS WILL NEED TO
BE BROUGHT DOWN.

.AVIATION...FOR MCCARRAN...SOUTHWEST WINDS UP TO 12 KTS EXPECTED
THROUGH TONIGHT. WINDS WILL INCREASE TUESDAY AFTERNOON WITH SPEEDS
BETWEEN 10-20 KTS DEVELOPING BY EARLY AFTERNOON. A COLD FRONT WILL
MOVE THROUGH SOUTHERN NEVADA AROUND MIDNIGHT WEDNESDAY SHIFTING THE
WINDS TO THE NORTH WITH SPEEDS INCREASING TO AROUND 15-25 KTS AND
POTENTIALLY HIGHER GUSTS WEDNESDAY MORNING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...MOST LOCATIONS WILL SEE SOUTHWEST WINDS AROUND 10 KTS
THROUGH TONIGHT WITH AN INCREASE IN SOUTHWEST WINDS TUESDAY. WINDS
WILL GENERALLY BE BETWEEN 10-20 KTS WHILE MUCH OF MOHAVE COUNTY WILL
SEE SOUTHWEST WINDS 20-30 KTS WITH GUSTS TO AROUND 40 KTS. OTHER
THAN A FEW CLOUDS AOA 15K SKIES WILL REMAIN MOSTLY CLEAR.

.FIRE WEATHER...WINDS WILL INCREASE TUESDAY AHEAD OF AN APPROACHING
FRONT AND LOOK TO BE FAIRLY STRONG ACROSS MUCH OF MOHAVE COUNTY. THE
RED FLAG WARNING STILL LOOKS GOOD WITH THE COMBINATION OF STRONG
WINDS AND RELATIVE HUMIDITY DROPPING INTO THE SINGLE DIGITS. LOCALLY
BREEZY NORTH WINDS WILL DEVELOP BEHIND THE FRONT TUESDAY NIGHT AND
WEDNESDAY WHILE HUMIDITY REMAINS LOW. THERE IS A PRETTY GOOD CHANCE
WIND SPEEDS WILL APPROACH OR EXCEED RED FLAG CRITERIA DOWN THE
COLORADO RIVER VALLEY AND A FIRE WEATHER WATCH REMAINS IN EFFECT.
