AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
221 AM PDT THU OCT 29 2015

.SYNOPSIS...LOW PRESSURE WILL MOVE THROUGH THE AREA TODAY WITH
PARTLY TO MOSTLY CLOUDY SKIES AND A CHANCE OF SHOWERS MAINLY OVER
THE EASTERN PORTIONS OF THE FORECAST AREA. GUSTY NORTH WINDS ARE
EXPECTED ACROSS MUCH OF THE AREA TODAY AND FRIDAY WITH THE STRONGEST
WINDS EXPECTED IN INYO...ESMERALDA AND NYE COUNTIES TODAY BEFORE
SHIFTING TO THE COLORADO RIVER VALLEY ON FRIDAY. A PLEASANT DAY IS
FORECAST FOR HALLOWEEN BEFORE A SIGNIFICANT CHANGE IN THE WEATHER
PATTERN BRINGS COLDER...UNSETTLED WEATHER TO THE SOUTHWEST NEXT
WEEK.
&&

.SHORT TERM...TODAY THROUGH SATURDAY NIGHT.

OVERNIGHT SHOWER ACTIVITY HAS BEEN EXTREMELY LIGHT WITH ONLY A GAUGE
OR TWO REPORTING ANY PRECIPITATION AT ALL. AT 2 AM, RADAR SHOWED
MAINLY LIGHT RETURNS NORTH OF I-15 WITH MORE ENHANCED SHOWER
ACTIVITY OVER SOUTHEAST SAN BERNARDINO AND MOHAVE COUNTIES. AN
ISOLATED THUNDERSTORM HAS FORMED NORTH OF INTERSTATE 40 SOUTHWEST OF
LAUGHLIN EAST OF THE TROUGH AXIS WHILE CLOUD COVER OVERALL IS
THINNING AND SHOWER ACTIVITY DIMINISHING IN THE WESTERN PORTIONS OF
THE CWA WITH INCREASING SUBSIDENCE BEHIND THE TROUGH.

THE TROUGH AXIS IS FORECAST TO SHIFT ACROSS THE FORECAST AREA TODAY
WITH THE COLD CORE MOVING FROM ITS 2 AM POSITION OVER NORTHERN SAN
BERNARDINO TO ITS FORECASTED POSITION SOUTHEAST OF THE FORECAST AREA
BY 5 PM THIS AFTERNOON. SHOWER CHANCES WILL BE LIMITED TO THE
EASTERN HALF OF THE AREA TODAY WITH THE BEST CHANCES OVER MOHAVE AND
EASTERN LINCOLN COUNTY. THERE COULD BE A FEW ISOLATED THUNDERSTORMS
PRODUCING MODERATE RAIN MIXED IN AS WELL. AN INCREASING NORTHERLY
FLOW OVER THE WESTERN HALF OF THE AREA WILL BRING IN DRIER AIR AND
GUSTY WIND CONDITIONS TODAY. MODELS INDICATE THE STRONGEST WINDS
WILL BE ALONG THE OWENS VALLEY, IN DEATH VALLEY AND IN ESMERALDA
COUNTY AND PORTIONS OF NYE COUNTY. NORTH WIND GUSTS 40-50 MPH ARE
POSSIBLE WITH AREAS OF BLOWING DUST. A WIND ADVISORY WILL BE ISSUED
FOR THESE AREAS. ELSEWHERE, WINDS WILL BE GUSTY BUT NOT AS STRONG.
ONE EXCEPTION MAY BE IN THE YUCCA VALLEY/TWENTYNINE PALMS AREA WHERE
GUSTS COULD APPROACH WIND ADVISORY CRITERIA. SINCE IT IS MARGINAL,
THIS AREA WILL NOT BE INCLUDED IN THE ADVISORY.

THE STRONGEST WINDS SHIFT TO THE COLORADO RIVER VALLEY ON FRIDAY
WITH GUSTS TO AROUND 40 MPH EXPECTED...ESPECIALLY BELOW HOOVER DAM
DOWN THROUGH LAUGHLIN, NEEDLES AND LAKE HAVASU CITY. A WIND ADVISORY
WILL BE ISSUED FOR THESE AREAS TO HIGHLIGHT THE CONCERN.

PLEASANT FALL CONDITIONS ARE EXPECTED ON HALLOWEEN WITH NEAR NORMAL
TEMPERATURES UNDER WITH LIGHT WINDS AND CLEAR SKIES.

.LONG TERM...SUNDAY THROUGH THURSDAY.

THERE REMAINS GOOD MODEL AGREEMENT THAT A HIGHLY AMPLIFIED LONGWAVE
TROUGH WILL SET UP OVER THE GREAT BASIN FOR THE FIRST HALF OF NEXT
WEEK. WHILE SUNDAY IS STILL EXPECTED TO BE DRY AND MILD, OUR FIRST
IN A SERIES OF SHORTWAVES WILL BE ON THE DOORSTEP OF ESMERALDA AND
INYO COUNTIES BY LATE SUNDAY NIGHT. MODELS ARE STILL OFF ON THE
OVERALL STRENGTH OF THE TROUGH, SHORTWAVE TIMING, AND PRECIP
AMOUNTS, BUT PRECIP CHANCES SEEM TO BE GREATEST MONDAY WITH THE
FIRST WAVE/PV ANOMALY AND WEDNESDAY WITH ANOTHER WAVE SLIDING
THROUGH. YET ANOTHER WAVE APPEARS TO GET IN HERE THURSDAY AND THAT
SEEMS TO HELP PUSH THE ENTIRE COMPLEX EAST, USHERING IN DRY
CONDITIONS FROM WEST TO EAST.

THIS SYSTEM WILL BRING COLDER TEMPERATURES TO THE REGION, WITH
READINGS 12-18 DEGREES BELOW NORMAL BY WEDNESDAY. SNOW LEVELS SHOULD
DROP TO ROUGHLY 4500 FEET ACROSS OUR NORTHERN FORECAST AREA TO 5500
FEET ACROSS OUR SOUTH BY WEDNESDAY AFTERNOON. AS MENTIONED IN THE
PREVIOUS DISCUSSION, THIS SHOULD SPELL THE END OF THE GROWING SEASON
IN MANY VALLEYS OF THE SOUTHERN GREAT BASIN TUESDAY INTO WEDNESDAY.
ADDITIONALLY, WHERE THE PRECIP FALLS WILL CREATE WET ROADS IN THE
LOWER ELEVATIONS AND SNOW COVERED ROADS IN THE HIGHER ELEVATIONS.
SOME TRAVEL IMPACTS ARE CERTAINLY POSSIBLE NEXT WEEK.
&&

.AVIATION....AVIATION...FOR MCCARRAN...BKN SKY CONDITIONS WILL
PERSIST THIS MORNING WITH CIGS GENERALLY ABOVE 10K FEET. A FEW LIGHT
SHOWERS WILL BE POSSIBLE THROUGH THE DAY WITH THE BEST CHANCE OVER
THE MOUNTAINS. GUSTY NORTHWEST WINDS WILL CONTINUE ALL DAY BUT COULD
POSSIBLY TURN MORE NORTH TO NORTHEAST AT TIMES...ESPECIALLY IF WINDS
LIGHTEN UP.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...A CHANCE OF SHOWERS WILL CONTINUE TODAY ACROSS PORTIONS
OF LINCOLN...CLARK...EASTERN SAN BERNARDINO AND MOHAVE COUNTIES.
GUSTY NORTH WINDS ARE EXPECTED TO PUSH ACROSS THE REGION THROUGH
THIS AFTERNOON. GUSTY NORTH WINDS AND DRY CONDITIONS EXPECTED AREA
WIDE FRIDAY.
