NATIONAL WEATHER SERVICE LAS VEGAS NV
0323 AM PST TUE DEC 16 2025
KEY MESSAGES

UPCOMING WEEK.
* A DISTURBANCE WILL BRING A 15-30% CHANCE FOR PRECIPITATION TO
PORTIONS OF INYO AND ESMERALDA COUNTIES LATE WEEK.
DISCUSSION
THROUGH SUNDAY.
ACTIVE PACIFIC STORM TRACK REMAINS FOCUSED WELL TO OUR NORTH WHILE
BROAD RIDGING CONTINUES TO DOMINATE THE SOUTHWESTERN US. THIS WILL
KEEP OUR SKIES MOSTLY CLEAR AND TEMPERATURES WELL ABOVE NORMAL.
MEANWHILE, LOW SUN ANGLES AND LIGHT SURFACE WINDS PROMOTE
INVERSIONS IN CERTAIN NARROW VALLEYS INCLUDING DEATH VALLEY, WHICH
MEANS TEMPERATURES WILL STAY RELATIVELY COOL FOR THOSE LOCATIONS
THROUGH AT LEAST MIDWEEK.
THE FLOW PATTERN WILL BEGIN TO CHANGE LATE IN THE WEEK AND OVER
THE WEEKEND AS THE FLOW BECOMES MORE ZONAL. THIS WILL ALLOW
PACIFIC STORM SYSTEMS TO DRAG FURTHER SOUTH INTO NORTHERN
CALIFORNIA, AND BRING SOME MODEST LIGHT PRECIPITATION CHANCES TO
THE SIERRA CREST AND PARTS OF NORTHERN INYO/ESMERALDA COUNTIES.
OTHERWISE, DRY CONDITIONS WILL PERSIST ELSEWHERE.
LOOKING AHEAD, A MORE SIGNIFICANT PATTERN CHANGE LOOKS POSSIBLE
APPROACHING THE CHRISTMAS HOLIDAY AS DEEP TROUGHING TAKES SHAPE
OFF THE CALIFORNIA COASTLINE. THIS FLOW PATTERN HINTS AT SOME
PRECIPITATION OPPORTUNITIES IN THE LONGER RANGE THANKS TO
MOISTURE ADVECTION WITHIN A BROAD SOUTHERLY FLOW AHEAD OF THE
TROUGH AXIS. THIS POTENTIAL IS SUPPORTED BY THE CURRENT 8-14 DAY
CPC OFFICIAL OUTLOOK FAVORING ABOVE NORMAL PRECIPITATION CHANCES
FOCUSED ACROSS CALIFORNIA.
