AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
435 AM PDT WED MAY 14 2025
SYNOPSIS
SCATTERED LIGHT SHOWERS NORTH OF LAS VEGAS WILL END
EARLY THIS MORNING, LEAVING MOSTLY SUNNY TO PARTLY CLOUDY SKIES
LATER IN THE DAY. TEMPERATURES WILL BEGIN TO RECOVER TODAY AND WILL
RISE BACK TO NEAR NORMAL THURSDAY AND FRIDAY, BEFORE ANOTHER POTENT
SYSTEM BRINGS STRONG WINDS, CHANCES FOR RAIN, AND COOLER
TEMPERATURES AGAIN THIS WEEKEND.
SHORT TERM
THROUGH THURSDAY NIGHT. EARLY MORNING SATELLITE AND
RADAR LOOPS SHOWED CUMULUS CONGESTUS OVER MUCH OF LINCOLN AND NYE
COUNTIES, PARTS OF NORTHERN CLARK AND MOHAVE COUNTIES, WITH A TAIL
EXTENDING SOUTH THROUGH EASTERN INYO AND CENTRAL SAN BERNARDINO
COUNTIES, WITH A FEW LIGHT SHOWERS IN NYE COUNTY AND VIRGA
ELSEWHERE. SURFACE OBS SHOWED THE COLD FRONT HAD PASSED THROUGH THE
COLORADO RIVER VALLEY AND WAS NEARING KINGMAN. BEHIND THE FRONT,
NORTHWESTERLY WINDS WERE GUSTING 30 TO 50 MPH, ALTHOUGH THIS WILL
LIKELY BE SHORT-LIVED. TEMPERATURES ACROSS MOST OF THE REGION WERE
FIVE TO TEN DEGREES COOLER THAN 24 HOURS AGO. HIGH RESOLUTION MODELS
SHOW THE CLOUDS SHREDDING OUT LATER THIS MORNING AND WINDS
DECREASING SOME, ALTHOUGH GUSTS OF 20 TO 30 MPH WILL LIKELY PERSIST
THROUGH THE DAY, ESPECIALLY IN SPOTS PRONE TO NORTHWEST WINDS.
TEMPERATURES WILL BE NEAR TO SLIGHTLY WARMER THAN YESTERDAY OVER
MOST OF THE AREA, FOLLOWED BY SEVERAL DEGREES OF WARMING THURSDAY
WHICH WILL PUSH TEMPS UP TO NEAR NORMAL FOR MID MAY.
LONG TERM
FRIDAY THROUGH TUESDAY.
AFTER A QUIESCENT FEW DAYS, A PATTERN SHIFT IS AHEAD FOR THE END OF
THIS WEEK AND INTO THE UPCOMING WEEKEND. FOR SEVERAL DAYS, CLUSTER
ANALYSES AND ENSEMBLE GUIDANCE HAVE REMAINED IN AGREEMENT REGARDING
THE NEXT SYSTEM TO IMPACT THE REGION. EFFECTS FROM THIS SYSTEM WILL
FIRST BE FELT ON FRIDAY AS SOUTHERLY TO SOUTHWESTERLY BREEZES RAMP
UP, WITH ANOTHER WINDY TO VERY WINDY DAY EXPECTED ON SATURDAY. THE
PRECISE DEPTH AND TRAJECTORY OF THIS SYSTEM REMAIN IN QUESTION, AND
SUBTLE CHANGES WILL DICTATE HOW STRONG WINDS WILL BE AS WELL AS
WHERE THE STRONGEST WINDS WILL BE OBSERVED, ALONG WITH ASSOCIATED
PRECIPITATION CHANCES. FOR NOW, GIVEN CONTINUED INCREASING
CONFIDENCE REGARDING THIS WEEKEND'S SYSTEM, THOSE WITH OUTDOOR PLANS
SHOULD CHECK BACK OFTEN, AND PREPARE FOR WINDY CONDITIONS AS WELL AS
POTENTIAL RAIN SHOWERS SATURDAY AND SUNDAY. WHILE TEMPERATURES ARE
PROGGED TO PEAK ON FRIDAY, IT IS LIKELY THAT ANOTHER STINT OF WELL
BELOW NORMAL TEMPERATURES ARRIVES LATE IN THE WEEKEND INTO EARLY
NEXT WEEK BEFORE SLOW MODERATION OCCURS. STAY TUNED.
