950 AM PST SUN DEC 14 2025
KEY MESSAGES
* MILD CONDITIONS WITH LIGHT BREEZES CONTINUE ACROSS THE REGION
THROUGH THE UPCOMING WEEK.
* A DISTURBANCE WILL BRING A 10-25% CHANCE FOR PRECIPITATION TO
PORTIONS OF INYO COUNTY, MAINLY THE SIERRA CREST, LATE WEEK.
DISCUSSION
THROUGH NEXT WEEKEND.
WEAK DISTURBANCE UNDERCUTTING OUR BROAD WESTERN US RIDGE IS
SPREADING SOME HIGH CLOUDS ACROSS THE FORECAST AREA THIS MORNING,
BUT OTHERWISE NOT MUCH WEATHER OF NOTE FOR THE COMING DAYS. HIGH
PRESSURE RIDGING WILL REMAIN THE DOMINANT FORCE KEEPING
TEMPERATURES MILD AND WINDS LIGHT, WITH THE EXCEPTION OF SOME
NORTHERLY BREEZES ALONG THE COLORADO RIVER. THE LOW SUN ANGLE AND
LIGHT SURFACE WINDS WILL CONTINUE TO PROMOTE SURFACE INVERSIONS,
ESPECIALLY IN THE DEEPER NARROW VALLEYS, WITH SOME HAZE POSSIBLE.
BY MIDWEEK ONWARD, THE RIDGE WILL BEGIN TO DEAMPLIFY IN RESPONSE
TO AN ACTIVE PACIFIC JET STREAM TAKING AIM AT THE PACNW. THIS WILL
ALLOW FOR SOME VERY LOW PRECIPITATION CHANCES TO SPREAD INTO THE
EASTERN SIERRA LATE IN THE WEEK AND INTO THE WEEKEND AS ADDITIONAL
DISTURBANCES MORE THROUGH TO OUR NORTH. OTHERWISE, DRY AND MILD
CONDITIONS WILL CONTINUE THROUGH NEXT WEEKEND.
