AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
904 AM PDT WED JUN 27 2012
.SYNOPSIS...LOW PRESSURE SYSTEMS PASSING ACROSS THE PACIFIC
NORTHWEST WILL CONTINUE TO RESULT IN BREEZY TO LOCALLY WINDY
CONDITIONS ACROSS THE AREA DURING THE AFTERNOON AND EVENING HOURS
EACH DAY THROUGH THE WEEKEND. TEMPERATURES WILL REMAIN A FEW DEGREES
ABOVE NORMAL. OUTSIDE OF A FEW CUMULUS CLOUDS EACH AFTERNOON AND
EVENING OVER MOHAVE COUNTY...A CLEAR SKY IS EXPECTED.
&&
.UPDATE...TEMPS ARE RUNNING AHEAD OF YESTERDAY IN MOST AREAS THIS
MORNING. THE 12Z SOUNDING FROM OUR OFFICE SHOWED ABOUT 3C OF WARMING
IN THE 900-800 MB LAYER. IN ADDITION THE SHORTWAVE SEEN ON WATER
VAPOR APPROACHING NORCAL SHOULD ALSO HELP TO ENHANCE MIXING THIS
AFTERNOON. ALL OF THESE SHOULD HELP TO BUMP UP HIGHS TODAY A FEW
DEGREES OVER YESTERDAY. OVERALL THE CURRENT FORECAST LOOKS GOOD AND
I DO NOT SEE ANY NEED TO MAKE ANY CHANGES AT THIS TIME.
&&
.AVIATION...FOR MCCARRAN...SOUTH TO SOUTH-SOUTHWEST WINDS AT 14-18
KTS WITH GUSTS TO AROUND 25 KTS ESPECIALLY DURING THE AFTERNOON AND
EARLY EVENING HOURS. WINDS SHOULD DECREASE TO 8-12 KTS AROUND 03Z
THURSDAY. UNDER A CLEAR SKY.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...MAINLY SOUTH TO SOUTHWEST WINDS ACROSS THE AREA WITH
WIND SPEEDS GENERALLY 10-20 KTS WITH GUSTS TO AROUND 25 KTS EXCEPT
IN ESMERALDA...CENTRAL NYE AND WESTERN INYO COUNTIES WHERE SUSTAINED
WINDS OF 15-25 KTS WITH GUSTS OF 25-35 KTS ARE EXPECTED BETWEEN
18Z-02Z TODAY. A MAINLY CLEAR SKY IS EXPECTED.
&&
.PREVIOUS DISCUSSION...
ISSUED AT 330 AM PDT WED JUN 27 2012
.SHORT TERM...TODAY THROUGH FRIDAY NIGHT...THE PERSISTENT DRY
SOUTHWEST FLOW WILL HOLD OVER THE REGION AS THE SYNOPTIC PATTERN
KEEPS THE FORECAST AREA BETWEEN A MEAN TROUGH ALONG THE WEST COAST
AND A BROAD RIDGE OVER THE CENTRAL AND SOUTHERN STATES. THE MAIN
PROBLEM TODAY WILL AGAIN BE CRITICAL FIRE WEATHER CONDITIONS
PRIMARILY OVER EAST CENTRAL NEVADA WHICH WILL INCLUDE MUCH OF
LINCOLN COUNTY. THE PREVAILING MODERATE SOUTHWEST FLOW AND DEEP
MIXING THIS AFTERNOON WILL COMBINE WITH PERSISTENT SINGLE DIGIT RH
VALUES AND VERY DRY FUELS. THE LATEST WIND FIELDS FROM THE SREF AND
LOCAL HIGH RES MODELS SUPPORT SUSTAINED SOUTH TO SOUTHWEST WINDS OF
20-25 MPH WHICH WOULD LEAD TO GUSTS OVER 35 MPH THIS AFTERNOON
THROUGH EARLY EVENING OVER THE NORTHERN TWO-THIRDS OF LINCOLN
COUNTY. GUSTS OF 20-30 MPH WILL BE COMMON ACROSS MUCH OF THE REST OF
THE FORECAST AREA. WIND SPEEDS MAY BE SIMILAR THURSDAY INTO FRIDAY
THOUGH TRENDING SLIGHTLY LOWER. THE OPERATIONAL MODELS STILL
INDICATE THE WESTERN EDGE OF ARIZONA MOISTURE CLOSE TO MOHAVE COUNTY
TODAY AND THURSDAY THOUGH PROBABLY ONLY ENOUGH FOR OCCASIONAL
CUMULUS CLOUDS. MOISTURE PUSHES FARTHER TO THE EAST AND SOUTHEAST
FRIDAY AS A CLOSED HIGH BECOMES CENTERED ALONG THE ARIZONA NEW
MEXICO BORDER. TEMPERATURES WILL CLIMB A FEW DEGREES TODAY THEN A
DEGREE OR SO MORE THURSDAY AND HOLD THROUGH FRIDAY.
&&
.LONG TERM...SATURDAY THROUGH TUESDAY...THE CWA WILL BE SANDWICHED
BETWEEN HIGH PRESSURE TO THE EAST AND SOUTHEAST AND TROUGHINESS TO
THE WEST AND NORTHWEST. THIS WILL LEAD TO CONTINUED DRY CONDITIONS
ACROSS THE AREA WITH POTENTIALLY GUSTY SOUTHWEST WINDS OVER THE
NORTHERN HALF OF THE CWA. WILL BE KEEPING AN EYE ON A POTENTIAL
EASTERLY WAVE THAT BOTH THE ECMWF AND CANADIAN HAVE PICKED UP ON.
THEY BOTH TRACK THIS FEATURE WEST ACROSS NORTHERN MEXICO AND
EVENTUALLY INTO ARIZONA. THIS LIKELY WILL NOT AFFECT OUR AREA ANY
EARLIER THAN THE MIDDLE OF NEXT WEEK...BUT ITS STILL WORTH WATCHING.
TEMPERATURES ARE FORECAST TO BE SLIGHTLY ABOVE NORMAL THROUGH THE
PERIOD.
&&
.FIRE WEATHER...CRITICAL FIRE WEATHER CONDITIONS WILL LIKELY PERSIST
OVER EAST CENTRAL NEVADA TODAY WHICH WILL INCLUDE MUCH OF LINCOLN
COUNTY. THE PREVAILING MODERATE SOUTHWEST FLOW AND DEEP MIXING THIS
AFTERNOON WILL COMBINE WITH PERSISTENT SINGLE DIGIT RH VALUES AND
VERY DRY FUELS. GUSTS OVER 35 MPH THIS AFTERNOON THROUGH EARLY
EVENING LOOK LIKELY OVER THE NORTHERN TWO-THIRDS OF LINCOLN COUNTY.
GUSTS OF 20-30 MPH WILL BE COMMON ACROSS MUCH OF THE REST OF THE
FORECAST AREA. WIND SPEEDS MAY BE SIMILAR THURSDAY INTO FRIDAY
THOUGH TRENDING SLIGHTLY LOWER WHILE A DRY AIR MASS REMAINS IN
PLACE.
A MID/UPPER LEVEL TROUGH IS FORECAST TO MOVE EAST ACROSS THE AREA ON
SUNDAY WHICH MAY RESULT IN AN INCREASE IN WINDS AND COULD RESULT IN
WINDS HIGH ENOUGH TO WARRANT ADDITIONAL FIRE WEATHER HEADLINES.
