AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
330 AM PDT MON APR 29 2013

.SYNOPSIS...DRY CONDITIONS ARE EXPECTED WITH RECORD TO NEAR RECORD
HIGH TEMPERATURES IN SOME AREAS THROUGH TUESDAY. HOWEVER A DRY COLD
FRONT WILL COOL TEMPERATURES ACROSS THE NORTH ON TUESDAY AND
AREAWIDE ON WEDNESDAY. HIGH TEMPERATURES BY WEDNESDAY WILL BE 10 TO
15 DEGREES COOLER THAN THOSE SEEN THIS AFTERNOON. WITH THE
COOLING...LOCALLY GUSTY WINDS WILL BE SEEN ON TUESDAY WHICH WILL
THEN CONTINUE WEDNESDAY AND THURSDAY.
&&

.SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT...DRY NORTHWEST FLOW
ALOFT WILL CONTINUE OVER THE CWA TODAY AND ALLOW FOR AFTERNOON HIGH
TEMPERATURES TO BE RECORD TO NEAR RECORD READINGS ONCE AGAIN. BY
TUESDAY A SHORT WAVE TROUGH CURRENTLY OVER WESTERN BRITISH COLUMBIA
CANADA WILL SAG SOUTHEAST AND DROP DOWN ACROSS THE ROCKY MOUNTAINS
LATE TUESDAY INTO WEDNESDAY. THIS WILL STRENGTHEN THE NORTHWEST FLOW
ALOFT SLIGHTLY...BUT THE MAIN IMPACT WILL BE A DRY COLD FRONT WHICH
WILL MOVE ACROSS THE SOUTHERN GREAT BASIN TUESDAY EVENING...BEFORE
EXITING THE CWA WEDNESDAY MORNING. THIS FRONT WILL BE RESPONSIBLE
FOR INCREASED WINDS ON TUESDAY WITH SOUTHWEST FLOW AHEAD AND
NORTHERLY WINDS BEHIND. THE STRONGEST WINDS APPEAR TO BE OVER MOHAVE
COUNTY DURING THE AFTERNOON TUESDAY AND ALTHOUGH THEY SHOULD REMAIN
BELOW WIND ADVISORY CRITERIA...POTENTIAL FIRE PROBLEMS ARE LIKELY.
AS THE FRONT MOVES ACROSS THE AREA...NORTH WINDS WILL THEN DEVELOP
WHICH THEN BECOME A PROBLEM ON WEDNESDAY...ESPECIALLY IN THE NORTH
WIND PRONE AREAS. POSSIBLE LAKE WIND ADVISORIES OR EVEN WIND
ADVISORIES...GUSTS TO OVER 40 MPH...MAY BE NEEDED FOR THE LAKE MEAD
NRA FOR WEDNESDAY LATE MORNING/AFTERNOON. WILL HOLD OFF ON ANY
STATEMENTS FOR THIS AREA WITH THIS PACKAGE HOWEVER.

ALTHOUGH A SLIGHT INCREASE IN CLOUDS WILL BE SEEN AS THE SHORT
WAVE/FRONT CROSSES OVER THE AREA...MOISTURE IS VERY LIMITED AND THE
BEST DYNAMICS REMAIN WELL TO THE EAST OF THE AREA...SO LOOKING AT
DRY CONDITIONS.

BESIDES THE WINDS ANOTHER IMPACT WITH THE FRONTAL PASSAGE WILL
BE MUCH COOLER TEMPERATURES. RECORD TO NEAR RECORD TEMPERATURES ARE
EXPECTED ACROSS MUCH OF THE CWA TODAY WITH COOLER TEMPERATURES
ACROSS THE NORTH ON TUESDAY AS THE FRONT DROPS SOUTH...BUT LITTLE
CHANGE IS EXPECTED TO THE TEMPERATURES OVER THE SOUTHERN PORTIONS.
BY WEDNESDAY HOWEVER...MOST READINGS WILL BE BETWEEN 10 AND 15
COOLER THAN WHAT IS EXPECTED THIS AFTERNOON...RESULTING IN
TEMPERATURES NEAR NORMAL ON WEDNESDAY.

.LONG TERM...NORTHERLY FLOW WILL REMAIN IN PLACE THURSDAY THROUGH
MONDAY AS AN AREA OF LOW PRESSURE DEEPENS OVER THE PLAINS AND HIGH
PRESSURE BUILDS ACROSS THE EASTERN PACIFIC. BASED ON THE RATHER
LARGE ENSEMBLE SPREAD WITH THE DOWNSTREAM LOW...THERE IS STILL A
FAIR AMOUNT OF UNCERTAINTY OVER THE WEEKEND FOR OUR AREA...WITH THE
MAIN ISSUE BEING A TROUGH DROPPING SOUTH IN THE FLOW AND PASSING
OVER THE FORECAST AREA LATE IN THE WEEKEND. HAVE OPTED TO KEEP THE
FORECAST DRY FOR NOW...AS THE LOW IS STILL PROGGED TO BE FAR ENOUGH
EAST TO HAVE MINIMAL IMPACT. MAY HAVE TO INTRODUCE SLIGHT CHANCES OF
PRECIP IF MODELS TREND ANY FURTHER WEST...BUT FOR NOW TEMPERATURES
ARE EXPECTED TO TREND UP THROUGH FRIDAY AND REMAIN ABOVE NORMAL
THROUGH THE WEEKEND WITH DRY CONDITIONS.
&&

.AVIATION...FOR MCCARRAN...LIGHT AND VARIABLE WINDS CAN BE EXPECTED
TODAY...BECOMING SOUTHWEST BY EARLY EVENING. WINDS WILL THEN REMAIN
OUT OF THE SOUTHWEST AND INCREASE ON TUESDAY...SHIFTING TO THE NORTH
EARLY WEDNESDAY MORNING AS A COLD FRONT PASSES ACROSS THE REGION.
TAILWINDS GREATER THAN 10KTS CAN BE EXPECTED WEDNESDAY AND POSSIBLY
THURSDAY THIS WEEK FOR RUNWAYS 1 AND 19.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...RELATIVELY LIGHT WINDS FOLLOWING TYPICAL
DAYTIME/NIGHTTIME DIURNAL PATTERNS EXPECTED TODAY..WITH INCREASED
SOUTHWESTERLY WINDS DEVELOPING ON TUESDAY AHEAD OF AN APPROACHING
COLD FRONT.
&&

.FIRE WEATHER...VERY WARM AND DRY CONDITIONS WILL CONTINUE THROUGH
TUESDAY WITH RECORD TO NEAR RECORD HIGHS EXPECTED OVER PORTIONS OF
THE AREA. A STORM MOVING SOUTH ALONG THE ROCKY MOUNTAINS WILL
BRING A DRY COLD FRONT ACROSS THE REGION BY LATE TUESDAY/EARLY
WEDNESDAY. INCREASED SOUTHWEST WINDS WILL BE SEEN AHEAD OF THIS
FRONT WITH NORTHERLY WINDS BEHIND. THE STRONGEST WINDS ON TUESDAY
ARE EXPECTED OVER MOHAVE COUNTY ARIZONA WHERE SOUTHWEST WINDS
GUSTING TO 35 MPH OR GREATER ARE LIKELY. THESE WINDS ALONG WITH
SINGLE DIGIT RELATIVE HUMIDITY VALUES AND DRY FUELS WILL THEN CREATE
THE POTENTIAL FOR ERRATIC FIRE BEHAVIOR AND THE FIRE WEATHER WATCH
FOR AZZ102 FOR TUESDAY AFTERNOON WILL BE UPGRADED TO A RED FLAG
WARNING WITH THIS MORNINGS PACKAGE.

NORTHERLY WINDS WILL THEN DEVELOP ON WEDNESDAY AND THURSDAY WITH
CONTINUED DRY CONDITIONS. THE MAIN IMPACT WILL BE SEEN IN THE
COLORADO RIVER ZONES WEDNESDAY LATE MORNING/AFTERNOON AND A FIRE
WEATHER WATCH WILL ALSO BE ISSUED WITH THIS MORNINGS PACKAGE FOR
THIS AREA FOR WEDNESDAY.
