NATIONAL WEATHER SERVICE LAS VEGAS NV
230 PM 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 15-30% CHANCE FOR PRECIPITATION TO
PORTIONS OF INYO AND ESMERALDA COUNTIES LATE WEEK.
DISCUSSION
THROUGH NEXT WEEKEND.
AN UPPER LEVEL RIDGE OVER THE WESTERN UNITED STATES MAINTAINS
UNSEASONABLY WARM TEMPERATURES FOR MOST OF THE AREA THROUGH THE END
OF THE WEEK. HIGH TEMPERATURES REMAIN 10 TO 15 DEGREES ABOVE AVERAGE
FOR MOST LOCATIONS, WHICH FOR LAS VEGAS MEANS HIGHS IN THE UPPER 60S
TO LOW 70S. DAILY HIGH TEMPERATURE AND WARM MINIMUM TEMPERATURE
RECORDS WILL BE IN JEOPARDY THROUGH THE END OF THE WEEK. SEE THE
CLIMATE SECTION BELOW FOR RECORD STATISTICS OVER THE NEXT FEW DAYS.
AT THE SAME TIME, 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.
THE POSITION OF THE HIGH MEANS BREEZY NORTHERLY WINDS PERSIST DOWN
THE COLORADO RIVER VALLEY THROUGH TUESDAY. AFTER TUESDAY, ZONAL FLOW
ALOFT SHOULD CAUSE WINDS TO WEAKEN OVER THE COLORADO RIVER, BUT
STRENGTHEN OVER THE SIERRA CREST.
THE RIDGE WILL BEGIN TO DEAMPLIFY MIDWEEK AS A SYSTEM MOVES INTO THE
PACIFIC NORTHWEST. ZONAL FLOW WILL ADVECT MOISTURE FROM THE PACIFIC
OCEAN TOWARDS THE FORECAST AREA, BUT MOST OF IT WILL BE BLOCKED BY
THE SIERRA NEVADA AND LITTLE TO NO PRECIPITATION WILL REACH THE
SURFACE OUTSIDE OF THE SIERRA CREST THROUGH THE WORKWEEK. HOWEVER,
ADDITIONAL OPPORTUNITIES FOR PRECIPITATION ARRIVE OVER THE WEEKEND
AS A MORE FAVORABLE FLOW PATTERN SETS UP, PARTICULARLY OVER INYO AND
ESMERALDA COUNTIES. OTHER AREAS SHOULD STAY DRY.
AVIATION...FOR HARRY REID...FOR THE 18Z FORECAST PACKAGE
EXPECT
WINDS TO FOLLOW TYPICAL DIURNAL PATTERNS THROUGH THE TAF PERIOD WITH

EVENING.
FOR THE REST OF SOUTHERN NEVADA, NORTHWEST ARIZONA AND SOUTHEAST
CALIFORNIA...FOR THE 18Z FORECAST PACKAGE...WINDS FOLLOW TYPICAL
DAILY DIRECTIONAL PATTERNS WITH SPEEDS UNDER 10 KNOTS AT MOST
LOCATIONS. THE EXCEPTION WILL BE ALONG THE COLORADO RIVER VALLEY,
WHERE BREEZY NORTHERLY WINDS INCREASE THROUGH THE AFTERNOON. GUSTS

CLOUD COVER SHOULD START TO CLEAR OUT THIS EVENING.
