AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1106 AM PDT SAT SEP 13 2025
KEY MESSAGES
* QUIET WEATHER IS EXPECTED ACROSS THE AREA THROUGH THE MIDDLE OF
NEXT WEEK.
* MONSOON MOISTURE MAKES A RETURN TOWARD THE END OF NEXT WEEK.
DISCUSSION
THROUGH FRIDAY.
SEASONABLY COOL TEMPERATURES WILL CONTINUE AS A TROUGH OF LOW
PRESSURE CONTINUES TO TRAVERSE THE AREA TODAY. A RIDGE OF HIGH
PRESSURE BUILDS IN BEHIND THE EXITING TROUGH SUNDAY, INITIATING A
SLOW WARMING TREND THROUGH MID-WEEK. TEMPERATURES WILL RISE TO NEAR
NORMAL BY TUESDAY AND REMAIN NEAR TO OR SLIGHTLY ABOVE NORMAL
THROUGH THURSDAY. WIND WILL REMAIN LIGHT AND DIURNALLY TERRAIN-
DRIVEN THROUGH THIS PERIOD.
AS THE RIDGE MOVES EASTWARD, IT WILL SET UP OVER THE FOUR CORNERS
AREA, OPENING THE DOOR FOR MOISTURE TO SURGE NORTHWARD GIVING US
PERHAPS A LAST TASTE OF THE MONSOON FOR THE SEASON. THE TREND HAS
BEEN UPWARD IN THE AMOUNT OF MOISTURE THIS SURGE WILL BRING, WITH
OVER 1 INCH OF PRECIPITABLE WATER MOVING AS FAR NORTHWARD AS DEATH
VALLEY AND SOUTHERN LINCOLN COUNTY ON FRIDAY. WHAT DOES THIS MEAN
FOR THE CHANCE OF SHOWERS AND THUNDERSTORMS? THE POSSIBILITY WILL BE
THERE WITH THE ADDED MOISTURE, BUT THERE IS ALSO QUITE A BIT OF
UNCERTAINTY WHERE WE MAY SEE SIGNIFICANT CLOUD COVER WHICH COULD
LIMIT CONVECTION DEPENDING ON THE TIME OF DAY THE CLOUDS MOVE IN.
THIS IS STILL A WEEK OUT SO STAY TUNED AS THE FORECAST EVOLVES
THROUGH THE WEEK.
