NATIONAL WEATHER SERVICE LAS VEGAS NV
127 AM PDT SUN MAR 29 2026
KEY MESSAGES
* THERE WILL BE ONE MORE DAY OF ANOMALOUS EARLY-SEASON HEAT BEFORE
COOLER TEMPERATURES ARRIVE LATER IN THE WEEK.
* A PATTERN SHIFT WILL BRING NEAR NORMAL TEMPERATURES, BREEZY
WINDS, AND PRECIPITATION CHANCES BY THE MIDDLE-TO-END OF NEXT
WEEK.
DISCUSSION
THROUGH SATURDAY.
HIGH PRESSURE BRINGS ONE MORE DAY OF RECORD-BREAKING TEMPERATURES
TODAY BEFORE COOLER TEMPERATURES ARRIVE LATER THIS WEEK. LAS VEGAS
HAS BROKEN OR TIED DAILY RECORD HIGHS FOR 11 DAYS IN A ROW NOW, AND
IF THE FORECAST PLAYS OUT AS EXPECTED, IT WILL EXTEND THE STREAK TO
12 DAYS TODAY. HIGH TEMPERATURE AND WARM MINIMUM TEMPERATURE RECORDS
ARE IN JEOPARDY FOR MOST CLIMATE SITES TODAY - SEE THE CLIMATE
SECTION BELOW FOR DETAILS. ANOTHER WEAK DISTURBANCE TRAVERSES THE
REGION, BRINGING SOUTHWESTERLY WINDS GUSTING 20 TO 30 MPH TO MUCH OF
THE MOJAVE DESERT THIS AFTERNOON.
A PATTERN SHIFT BEGINS ON MONDAY AS A SERIES OF TROUGHS MOVE THROUGH
THE WESTERN UNITED STATES AND THE RIDGE WEAKENS. EXPECT A 10 TO 15
DEGREE DECREASE IN TEMPERATURES BETWEEN TODAY AND WEDNESDAY, AT
WHICH POINT HIGHS WILL BE WITHIN A FEW DEGREES OF NORMAL FOR EARLY
APRIL. A FEW DEGREES OF ADDITIONAL COOLING IS POSSIBLE BY FRIDAY AS
A STRONGER AREA OF LOW PRESSURE MOVES THROUGH THE GREAT BASIN.
ANOTHER NOTABLE IMPACT WILL BE GUSTY WINDS MONDAY THROUGH THURSDAY,
WITH THE STRONGEST WINDS IN WESTERN SAN BERNARDINO COUNTY. HIGH
RESOLUTION GUIDANCE HAS BACKED OFF WIND SPEEDS ON MONDAY AND GUSTS
SHOULD GENERALLY BE LESS THAN 40 MPH OUTSIDE OF HIGH TERRAIN.
HOWEVER, WINDS INCREASE TUESDAY THROUGH THURSDAY, ESPECIALLY IN SAN
BERNARDINO, CLARK, AND MOHAVE COUNTIES. FOR LAS VEGAS, THE HIGHEST
PROBABILITY OF GUSTS REACHING 40 MPH IS 50 PERCENT ON THURSDAY.
LASTLY, PRECIPITATION RETURNS TO THE FORECAST ON TUESDAY AND
WEDNESDAY. A NORTHERLY PLUME OF MOISTURE WILL MOVE INTO THE EASTERN
SIERRA AND SOUTHERN GREAT BASIN, BUT THIS SHOULD BE RELATIVELY WEAK
AND INTERCEPTED BY MOUNTAINS. HOWEVER, ANOTHER PLUME OF MOISTURE
WILL APPROACH THE REGION FROM THE SOUTHWEST AND SHOULD REACH
SOUTHERN NEVADA AND NORTHWESTERN ARIZONA. FOR THIS PLUME, GUIDANCE
IS SHOWING A STRONGER AND MORE NORTHERLY SOLUTION COMPARED TO
PREVIOUS MODEL RUNS, THUS ALLOWING THE SHORTWAVES TO TAP INTO THIS
MOISTURE SOURCE. WILL CONTINUE TO MONITOR TRENDS TO SEE IF IT
MAINTAINS THIS MORE FAVORABLE TRACK.
AVIATION...FOR HARRY REID
FOR THE 06Z FORECAST
PACKAGE...SOUTH WINDS WILL CONTINUE THROUGH THE NIGHT AT OR JUST
BELOW 8KT. AFTER A BRIEF LULL IN WINDS SUNDAY MORNING, GUSTY SOUTH
TO SOUTHWEST WINDS RETURN AROUND MIDDAY. WINDS WILL BE SIMILAR TO
YESTERDAY WITH GUSTS TO AROUND 25KT EXPECTED THROUGH THE AFTERNOON.
MOST LIKELY, WINDS WILL DIMINISH AROUND 03Z SUNDAY EVENING AND BE
LIGHT THROUGH THE NIGHT. WATCHING THE POTENTIAL FOR ELEVATED WEST TO
SOUTHWEST WINDS THAT WOULD PUSH THROUGH THE VALLEY SUNDAY EVENING
AND CONTINUE AT TIMES OVERNIGHT, WHICH WOULD RESULT IN SPEEDS AROUND
10KT AND OCCASIONAL GUSTS TO 15-20KT. PERIODS OF HIGH CLOUDS
EXPECTED AT OR ABOVE 20KFT WILL CONTINUE THROUGH SUNDAY NIGHT.
FOR THE REST OF SOUTHERN NEVADA, NORTHWEST ARIZONA AND SOUTHEAST
CALIFORNIA...FOR THE 06Z FORECAST PACKAGE...LIGHT WINDS ARE EXPECTED
THROUGH EARLY SUNDAY MORNING. ANOTHER ROUND OF GUSTY WINDS WILL
DEVELOP SUNDAY AFTERNOON WITH SIMILAR CONDITIONS TO TODAY.
WIDESPREAD GUSTS 15-25KT ARE EXPECTED. MODERATE CONFIDENCE FOR A
WEST PUSH AT KBIH SUNDAY BETWEEN 23Z-03Z BEFORE LIGHT NORTH TO
NORTHWEST WINDS RETURN. VFR CONDITIONS WILL CONTINUE WITH PERIODS OF
SCT-BKN HIGH CLOUDS AT OR ABOVE 20KFT.
