NATIONAL WEATHER SERVICE LAS VEGAS NV
930 PM PDT SUN OCT 18 2026
KEY MESSAGES
* CLEARING SKIES AND COOL CONDITIONS FOR MOST AREAS TODAY BUT NON-
IMPACTFUL RAIN IS POSSIBLE AGAIN MONDAY MORNING FOR MOHAVE CO.
* A STRONGER SYSTEM WILL BRING INCREASED PRECIPITATION CHANCES AND
GUSTY WINDS TO THE REGION THE MIDDLE TO END OF THE WEEK.
DISCUSSION
THROUGH NEXT WEEKEND.
THE LINGERING SHOWERS FROM THE EARLY MORNING ARE ERODING ALONG WITH
MOST OF THE CLOUD COVER, LEADING TO CLEARING SKIES FOR THE MID TO
LATE AFTERNOON AND MOSTLY CLEAR SKIES OVERNIGHT. THIS WILL ALLOW FOR
SLIGHTLY WARMER AFTERNOON TEMPERATURES WITH HIGHS IN THE UPPER 70S
AND LOW 80S FOR MOST OF THE REGION (DEATH VALLEY WILL STILL PEAK IN
THE LOW 90S). THE CLEARING SKIES WILL ALLOW FOR GOOD COOLING
OVERNIGHT WITH MOST LOWS FALLING INTO THE 60S (70S FOR DEATH
VALLEY). CLOUD COVER RETURNS TO THE WESTERN PORTIONS OF THE CWA INTO
AFTERNOON MONDAY WITH A FEW MORE NON-IMPACTFUL SHOWERS POSSIBLE.
THESE RAIN CHANCES LOOK TO MOSTLY STICK TO MOHAVE CO AND DISSIPATE
INTO THE NIGHT.
THE NEXT RAIN SYSTEM WILL NOT BE AS MEEK. A TROUGH APPROACHES THE
AREA INTO THE MID WEEK WITH INITIAL SHOWERS AND LIGHT SNOW CHANCES
(FOR THE HIGHEST PEAKS) ARRIVING AT THE SIERRA NEVADA EARLY TUESDAY.
CHANCES FOR RAIN ON THIS INITIAL PUSH LOOK GOOD, BUT THERE WONT BE
MUCH IN THE WAY OF RAINFALL MOUNTS UNTIL THE TROUGH DIGS DEEPER INTO
SOUTHERN CALIFORNIA AND PULLS MORE MOISTURE FROM THE PACIFIC ON
WEDNESDAY. THE ORIENTATION OF THAT MOISTURE AND THE TROUGH ITSELF
WILL OFFER WIDESPREAD CHANCES FOR RAIN WEDNESDAY AND THURSDAY BEFORE
EXITING ON FRIDAY. MODELS CONTINUE TO ENTERTAIN SOME SNOW
ACCUMULATIONS ABOVE 9000 FT, BUT THE MOISTURE FAILS TO LINE UP WITH
THE COLDER AIR BEHIND THE TROUGH, LIMITING SNOW AMOUNTS. RAIN FOR
THE LOWER ELEVATIONS LOOKS LIGHT TO MODERATE FOR MOST OF WEDNESDAY
WITH A WAVE OF MODERATE TO LOCALLY INCREASED RAIN RATES POSSIBLE
LATE WEDNESDAY INTO THURSDAY MORNING. RAINFALL ACCUMULATIONS LOOK
FAIRLY MANAGEABLE WITH MOST AREAS SEEING 0.10" TO 0.50" AND HIGHER
PEAKS APPROACHING 0.75" BY THE TIME THE RAIN EXITS ON EARLY FRIDAY.
WINDS WILL BE MORE OF A FACTOR WEDNESDAY AFTERNOON WITH 40 MPH GUSTS
POSSIBLE, BUT EASING THAT NIGHT AND NOT REALLY RETURNING FOR
THURSDAY. TEMPERATURES WILL COOL INTO THE WEEKEND WITH HIGHS PEAKING
AROUND 70 FOR MOST AREAS, AND DEATH VALLEY PEAKING IN THE LOW 80S.
