AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
250 PM PST SUN FEB 1 2015

.SYNOPSIS...A STRONG AREA OF HIGH PRESSURE WILL HOLD ALONG THE
CALIFORNIA COAST PROVIDING A DRY WEATHER PATTERN FOR OUR REGION
THROUGH THE WEEK WITH TEMPERATURES RUNNING WELL ABOVE NORMAL.
&&

.SHORT TERM...THROUGH TUESDAY NIGHT.

ALTHOUGH A DRY WEATHER PATTERN IS IN STORE FOR OUR REGION..IT IS
WORTH POINTING OUT THE PACIFIC MOISTURE PLUME EXTENDING FROM THE
DATELINE TO THE PACIFIC NORTHWEST. THE ONLY THING WE WILL SEE FROM
THIS IS PERIODS OF CONSIDERABLE HIGH CLOUDS FOR THE EARLY PART OF
THE WEEK AS A MEAN RIDGE ALONG THE CALIFORNIA COAST DIRECTS THE
DEEPER MOISTURE INTO THE PACIFIC NORTHWEST. THIS PATTERN WILL
PROVIDE LIGHT WINDS AND A GRADUAL INCREASE IN TEMPERATURES WITH
READINGS SEVERAL DEGREES ABOVE NORMAL.

.LONG TERM...WEDNESDAY THROUGH SATURDAY.

GUIDANCE CONTINUES TO POINT AT A MEAN RIDGE PATTERN HANGING TOUGH
THROUGHOUT THE ENTIRE PERIOD. THIS WILL LEAD TO "SPRING LIKE"
TEMPERATURES...RUNNING SOME 10-15 DEGREES ABOVE SEASONAL NORMALS
THROUGH THE END OF THE PERIOD. DESPITE THIS...GUIDANCE CONTINUES TO
SUGGEST THAT HIGH TEMPERATURE RECORDS WILL BE JUST OUT OF REACH
UNTIL PERHAPS NEXT WEEKEND. THIS WILL BE WORTH MONITORING AS DETAILS
SUCH AS CLOUD COVER AND WIND ARE RESOLVED OVER THE COURSE OF THE
WEEK.

A SERIES OF SHORTWAVES EJECTING FROM A TROUGH OVER THE PACIFIC
WILL BRING HEAVY RAINFALL TO NORTHERN CALIFORNIA STARTING FRIDAY AND
LASTING INTO THE WEEKEND. THE STRONGEST SHORTWAVE WILL YIELD A
CHANCE OF SHOWERS IN THE SOUTHERN SIERRA FRIDAY INTO THE
WEEKEND...AS WELL AS ENHANCED RIDGE TOP WINDS ALONG THE CREST OF THE
SIERRA FRIDAY AND SATURDAY. OTHERWISE...THESE DISTURBANCES WILL
BRING INCREASED CLOUD COVER TO THE SOUTHERN GREAT BASING AND MOJAVE
DESERT THROUGH THE END OF THE PERIOD.
&&

.AVIATION...FOR MCCARRAN...TYPICAL LIGHT DIURNAL WINDS GENERALLY
LESS THAN 8 KTS ARE EXPECTED TONIGHT AND MONDAY WITH A SOUTHWEST
COMPONENT AT NIGHT AND AN EASTERLY COMPONENT IN THE AFTERNOON
HOURS. SIMILAR CONDITIONS WILL PERSIST THROUGH AT LEAST WEDNESDAY
WITH PERIODS OF CONSIDERABLE HIGH CLOUDS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...LIGHT WINDS AND PERIODS OF CONSIDERABLE HIGH CLOUDS CAN
BE EXPECTED THROUGH AT LEAST WEDNESDAY.
&&

.SPOTTER INFORMATION STATEMENT...SPOTTER ACTIVATION IS NOT EXPECTED
AT THIS TIME.
