AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
307 PM PDT SAT MAR 28 2015

.SYNOPSIS...DRY AND UNSEASONABLY WARM CONDITIONS WILL CONTINUE 
THROUGH THE MIDDLE OF NEXT WEEK. WEAK DISTURBANCES PASSING BY TO THE 
NORTH WILL KICK UP SOUTHERLY WINDS AT TIMES...ESPECIALLY TUESDAY AND 
WEDNESDAY. A STRONGER SYSTEM MAY BRING SIGNIFICANT COOLING TOWARD 
THE LATTER PART OF THE WEEK WITH HIGH TEMPERATURES POSSIBLY DROPPING 
CLOSE TO NORMAL FRIDAY.
&&

.DISCUSSION...TONIGHT THROUGH SATURDAY...THE MODELS ARE IN PRETTY 
DECENT AGREEMENT WITH THE OVERALL PATTERN THROUGH THIS PERIOD. A 
MEAN RIDGE WILL REMAIN OVER THE AREA THROUGH MONDAY LEADING TO 
RECORD OR NEAR RECORD TEMPERATURES AND GENERALLY DRY CONDITIONS. A 
WEAK DISTURBANCE RIDING OVER THE RIDGE MAY BRING JUST ENOUGH 
MOISTURE AND INSTABILITY TO OUR NORTHERN AREAS SUNDAY FOR A SLIGHT 
CHANCE OF SHOWERS OVER THE SIERRA IN NORTHWEST INYO COUNTY AND TO 
THE HIGHER TERRAIN IN NORTHERN LINCOLN COUNTY. THE RIDGE WILL GET 
PUSHED EAST TUESDAY AS A SLIGHTLY STRONGER SHORTWAVE MOVES INTO 
NORTHERN NEVADA. THIS SYSTEM LOOKS DRY BUT WILL KICK UP BREEZY 
SOUTH/SOUTHWEST WINDS. WE WILL HAVE TO KEEP AN EYE ON THE TRENDS FOR 
WESTERN SAN BERNARDINO COUNTY WHERE WE MAY END UP NEEDING A WIND 
ADVISORY. ANOTHER...DEEPER SHORTWAVE IS EXPECTED TO MOVE INTO 
NORTHERN NEVADA LATE WEDNESDAY AND WEDNESDAY NIGHT WITH ANOTHER ROUND 
OF GUSTY WINDS DEVELOPING ACROSS THE AREA AND THERE IS POTENTIAL FOR 
ADVISORY LEVEL WINDS. GIVEN THAT THIS SYSTEM IS DEEPER/STRONGER IT 
WILL PRODUCE A CHANCE OF SHOWERS OVER NORTHERN LINCOLN COUNTY 
THURSDAY WHILE GUSTY NORTHERLY WINDS USHER IN COOLER TEMPERATURES. 
THESE COOLER TEMPERATURES WILL CARRY INTO FRIDAY BEHIND THE EXITING 
SHORTWAVE. HIGH TEMPERATURES THURSDAY AND FRIDAY WILL FINALLY DROP 
TO NEAR NORMAL. YET ANOTHER TROUGH IS FORECAST TO APPROACH THE AREA 
FROM THE WEST OR NORTHWEST ON SATURDAY ALTHOUGH THE MODELS VARY WITH 
THE TIMING. FOR NOW IT LOOKS DRY AND POTENTIALLY BREEZY WITH A BIT 
OF A WARMUP. 

.AVIATION...FOR MCCARRAN...NO SIGNIFICANT CLOUD COVER EXPECTED 
THROUGH SUNDAY. SOUTH WINDS 10-15 KTS WITH GUSTS AROUND 20 KTS 
THROUGH EARLY EVENING THEN TYPICAL DRAINAGE SOUTH/SOUTHWEST 5-10 
KTS. WINDS MOST OF SUNDAY WILL BE MAINLY EASTERLY 8 KTS OR LESS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST 
CALIFORNIA...SOME INCREASE IN HIGH CLOUDS TONIGHT AND SUNDAY. A FEW 
CUMULUS CLOUDS THROUGH EARLY THIS EVENING FROM AROUND BIH EAST TO 
NORTHERN LINCOLN COUNTY. WINDS THROUGH THIS EVENING MAINLY 
SOUTH/SOUTHWEST 10-20 MPH DECREASING AFTER SUNSET...THEN PICKING 
BACK UP AGAIN BY SUNDAY AFTERNOON.
&&

.CLIMATE...LISTED BELOW ARE THE RECORD HIGHS FOR SATURDAY THROUGH 
MONDAY. RECORDS ARE POSSIBLE EACH DAY WITH THE GREATEST CHANCE ON 
SATURDAY.
