AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
313 PM PDT FRI MAR 19 2010
.SYNOPSIS...HIGH PRESSURE BUILDING IN OVER THE WEEKEND WILL RESULT
IN MOSTLY CLEAR SKIES WITH TEMPERATURES WARMING TO ABOUT 5 DEGREES
ABOVE NORMAL ON SUNDAY. OUR NEXT WEATHER MAKER WILL BE MOVING
THROUGH THE GREAT BASIN MONDAY AND TUESDAY. THE SYSTEM WILL BRING A
CHANCE OF SHOWERS MAINLY TO SOUTHERN NEVADA AND NORTHWEST ARIZONA
ALONG WITH GUSTY WINDS.
&&
.SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT...CANCELING WIND
ADVISORY FOR THE COLORADO RIVER ZONES EARLY AS LATEST REPORTS
INDICATE NONE OF THE STATIONS HAVE MET CRITERIA FOR SEVERAL HOURS
NOW. SETTING UP TO BE A WONDERFUL WEEKEND WITH HIGH PRESSURE OVER
THE FORECAST AREA LEADING TO LIGHTER WINDS SATURDAY AND WARMER
TEMPERATURES ON SUNDAY. A SPLIT TROUGH MOVES INTO THE WEST SUNDAY
NIGHT. THE STRONGER NORTHERN STREAM MOVES INTO THE NORTHWEST STATES
WHILE WEAKER SOUTHERN BRANCH LIES WEST OF NORTHERN BAJA. RH PROGS
INDICATE AN INCREASE IN HIGH CLOUDS SUNDAY NIGHT ASSOCIATED WITH THE
SOUTHERN BRANCH.
.LONG TERM...MONDAY THROUGH FRIDAY...CONTINUED DECENT MODEL
AGREEMENT AND NO SIGNIFICANT CHANGES IN THEM...HENCE VERY LITTLE
CHANGE FROM THE PREVIOUS FORECAST PACKAGE. THE WEEKEND RIDGE WILL
BEGIN TO BE KNOCKED DOWN MONDAY BY THE NEXT APPROACHING SYSTEM FROM
THE PACNW. THERE IS SPLIT FLOW AND STILL DO NOT EXPECT THE
TROUGH/LOW IN THE SOUTHERN BRANCH TO BE A FACTOR FOR OUR AREA AS IT
TRACKS FAR TO THE SOUTH. A CLOSED LOW FORMS EARLY TUESDAY IN IDAHO
AND TRACKS SOUTH ALONG THE NEVADA/UTAH BORDER AND THEN NEAR THE FOUR
CORNERS AREA WEDNESDAY. LIKE THE PREVIOUS FORECASTER MENTIONED THIS
SYSTEM LOOKS VERY SIMILAR TO THE ONE THAT WENT THROUGH YESTERDAY.
THE PRIMARY CONCERN WILL BE WINDS BEHIND THE FRONT. PRECIPITATION
LOOKS TO LIMITED AS WELL AND PRIMARILY CONFINED THE NORTHERN AND
NORTHEASTERN PARTS OF THE FORECAST AREA. TEMPERATURES WILL REBOUND
FROM THE WEEKS LOWEST TEMPERATURES ON WEDNESDAY AS RIDGING BUILDS
BACK OVER THE AREA.
&&
.AVIATION...FOR MCCARRAN...VARIABLE WINDS BUT PRIMARILY FAVORING THE
NORTHEAST WILL BE LESS THAN 10KTS THROUGH ABOUT SUNSET BEFORE GOING
LIGHT THEN LATER TONIGHT SHIFTING TO THE SOUTHWEST AND UNDER 8
KNOTS. SATURDAY WILL SEE LIGHT AND VARIABLE WINDS AND CLEAR SKIES.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...NORTH TO NORTHEAST WINDS ACROSS THE AREA WILL GENERALLY
BE AROUND 10KTS TONIGHT. SOME STRONGER WINDS ARE EXPECTED DOWN THE
COLORADO RIVER VALLEY TONIGHT AND SATURDAY WHERE WINDS MAY GUST TO
20KTS. CLEAR SKIES ANTICIPATED ACROSS THE ENTIRE AREA.
