AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
129 PM PDT WED SEP 2 2026
KEY MESSAGES
- DRIER, COOLER, AND BREEZY CONDITIONS EXPECTED THROUGH THE WORK WEEK.
- STORM CHANCES RETURN THIS WEEKEND WITH HIGHER RAIN POTENTIAL
FROM MONSOONAL PUSH AND POSSIBLE REMNANTS OF TROPICAL STORM MARIE.
DISCUSSION
MOSTLY CLEAR SKIES AND A COOLING TREND CONTINUES TODAY WITH HIGHS
AROUND 5 DEGREES BELOW AVERAGE. ASIDE FROM GUSTY WINDS (WITH PEAK
GUSTS AROUND 30MPH) THE FORECAST REMAINS FAIRLY CALM AND DRY WITH
DEW POINTS FALLING TO AROUND 10 DEGREES AND RH BEING LESS THAT 10
PERCENT. THURSDAY AND FRIDAY WILL CONTINUE THE RELATIVELY COOL
CONDITIONS (YES, HIGHS IN THE 90S ARE RELATIVELY COOL IN THE VALLEY
THIS TIME OF YEAR) WITH MONSOONAL INFLUENCE BEGINNING TO ADD SOME
SLIGHT IMPROVEMENT TO HUMIDITIES INTO THE AREA. WINDS WILL INCREASE
OVER THE NEXT FEW DAYS WITH HIGHER TERRAIN AND FAVORED GAPS BEGINNING
TO SEE GUSTS ABOVE 40 MPH THURSDAY AND FRIDAY AFTERNOON.
THE INCREASING WINDS AND BUILDING MOISTURE LOOK TO FUEL STORM
CHANCES OVER THE WEEKEND. SOME MID TO LONGER TERM MODELS ALSO SHOW A
PORTION OF THE REMNANTS FROM TROPICAL STORM ADDING TROPICAL MOISTURE
TO THE MIX OVER THE WEEKEND. THESE INGREDIENTS WILL COMBINE TO OFFER
STRONG CHANCES FOR FAIRLY WIDESPREAD SHOWERS AND STORMS ON SATURDAY
WITH INCREASED CHANCES ON SUNDAY AS OF THE MOST RECENT FORECAST
UPDATES. WHILE THERE IS STILL SOME CHANGES POSSIBLE FOR THIS PORTION
OF THE FORECAST, YOU MAY STILL WANT TO PREPARE FOR HAZARDOUS WEATHER
FOR THE HOLIDAY WEEKEND, ESPECIALLY SUNDAY. STORMS WILL OFFER PLENTY
OF LIGHTNING, RAIN, AND STRONG GUSTS. SHOWER CHANCES WILL BE MORE
WIDESPREAD AND WITH INCREASED THE PWATS OVER THE WEEKEND, COULD
PROVIDE HEAVY RAINFALL, LEADING TO FLOOD RISKS. ADDING TO THE RISK
OF FLOODING WILL BE THE POTENTIAL FOR STORM AND SHOWER TRACKS TO
TRAIN OVER PORTIONS OF THE REGION, LEADING TO PERSISTENT RAIN FALL.
RAIN CHANCES REDUCE INTO LABOR DAY, BUT LINGER INTO THE NEXT WORK
WEEK
