AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1224 PM PDT WED APR 1 2026
KEY MESSAGES
* BREEZY TO WINDY CONDITIONS WILL PERSIST THROUGH FRIDAY,
PARTICULARLY FROM SAN BERNARDINO COUNTY EAST TO THE COLORADO
RIVER VALLEY, INCLUDING INLAND LAKES.
* HIGH PRESSURE WILL GRADUALLY BUILD BACK INTO THE WESTERN U.S.
OVER THE WEEKEND INTO THE FIRST HALF OF NEXT WEEK. THIS WILL
BRING A RETURN OF UNSEASONABLE WARMTH, PERSISTENT DRY
CONDITIONS, AND LIGHTER WINDS.
DISCUSSION
BREEZY CONDITIONS CONTINUE TODAY MAINLY ACROSS WESTERN PORTIONS
OF SAN BERNARDINO WITHIN A FAVORABLE WESTERLY FLOW PATTERN. EXPECT
THESE WINDS TO LINGER INTO TOMORROW AFTERNOON/EVENING. WIND GUSTS
OF 40-50 MPH MAY OCCUR, PARTICULARLY OVERNIGHT TONIGHT INTO
TOMORROW. TOMORROW NIGHT INTO FRIDAY, A COMPACT SHORTWAVE TROUGH
WILL MOVE ACROSS THE PACIFIC NORTHWEST. THIS WILL RESULT IN
CONTINUED BREEZY CONDITIONS, BUT AS WINDS SHIFT TO THE NORTH IN
THE WAKE OF THIS SYSTEM, A NOTED UPTICK IN WIND SPEED AND GUSTS
WILL TAKE SHAPE ACROSS THE COLORADO RIVER VALLEY. THIS WILL BEGIN
LATE THURSDAY NIGHT/EARLY FRIDAY AND LAST INTO FRIDAY NIGHT. HREF
AND NBM PROBABILITIES OF 40-50 MPH GUSTS ARE IN THE 70-100% RANGE,
SO THIS WILL BE ONE OF THE STRONGER NORTHERLY WIND EVENTS WE'VE
SEEN IN A WHILE. ALONG WITH THESE WINDS, EXPECT HAZARDOUS BOATING
CONDITIONS ON LAKES MEAD, MOHAVE AND HAVASU. ADDITIONALLY, EXPECT
AREAS OF BLOWING DUST AND REDUCED VISIBILITIES IN AREA ROADS.
ADVISORIES ARE CURRENTLY IN EFFECT FOR PORTIONS OF SAN BERNARDINO
COUNTY AND ADDITIONAL HEADLINES WILL LIKELY BE NECESSARY FOR THE
COLORADO RIVER VALLEY AND AREA LAKES.
A RELATIVELY COOL SPELL WILL TAKE HOLD IN THE WAKE OF NORTHERLY
FLOW SATURDAY INTO SUNDAY, BUT A NOTED WARMUP IS EXPECTED HEADING
INTO NEXT WEEK. THIS WILL OCCUR AS UPPER RIDGING BEGINS TO BUILD
INTO THE DESERT SOUTHWEST ONCE AGAIN. HOWEVER, UNLIKE THE
EXTREMELY ANOMALOUS RIDGE WE SAW IN MARCH, THIS LOOKS TO BE A BIT
MORE MEASURED. STILL, IT WILL RESULT IN A PERIOD OF DRY AND
UNSEASONABLY WARM CONDITIONS WITH HIGHS RETURNING TO THE 80S TO
MID 90S IN THE LOWER ELEVATIONS. LIGHTER WINDS WILL ALSO TAKE HOLD
FOR AT LEAST THE FIRST HALF OF THE WEEK. BEYOND MIDWEEK, MUCH
UNCERTAINTY EXISTS WITH ENSEMBLES SUGGESTING THE PATTERN MAY
REMAIN PROGRESSIVE WITH OPPORTUNITIES FOR WEAK UPPER WAVES/TROUGHS
EMERGING FROM THE PACIFIC. HOWEVER, CONFIDENCE ON THEIR EVENTUAL
PROGRESSION AND MEANINGFUL LOCAL IMPACTS REMAINS LOW.
AVIATION...FOR HARRY REID...FOR THE 18Z FORECAST PACKAGE
GUSTY
SOUTHWESTERLY WINDS ARE EXPECTED ONCE AGAIN THIS AFTERNOON AND
EVENING, WITH GUSTS OF 25 TO 30 KNOTS LIKELY. A PERIOD OF STRONGER
WINDS IS POSSIBLE AFTER 07Z, WHEN A FEW WESTERLY GUSTS TO 35 KNOTS
ARE POSSIBLE. SOME IMPROVEMENT IN WINDS IS EXPECTED THURSDAY
MORNING, BUT BREEZY SOUTHWEST WINDS WILL REDEVELOP TOMORROW
AFTERNOON, BEFORE SHIFTING TO THE NORTHWEST IN THE EVENING. VFR
CONDITIONS WILL PREVAIL THROUGH THE TAF PERIOD, WITH FEW TO SCT
CLOUDS WITH BASES AOA 15KFT AGL INTO THIS AFTERNOON, IMPROVING TO
AROUND 20KFT AGL THIS EVENING AND THURSDAY.
FOR THE REST OF SOUTHERN NEVADA, NORTHWEST ARIZONA AND SOUTHEAST
CALIFORNIA...FOR THE 18Z FORECAST PACKAGE...SOUTHWEST WINDS WILL
CONTINUE ACROSS MOST OF THE AREA INTO THIS EVENING, WITH THE
STRONGEST WINDS EXPECTED ACROSS THE WESTERN MOJAVE DESERT NEAR KDAG.
THE EXCEPTION TO THIS WILL BE IN THE OWENS VALLEY WHERE DOWNSLOPE
WINDS OFF THE SIERRA COULD RESULT IN GUSTS OF 30 TO 40 KNOTS JUST
EAST OF THE MOUNTAINS. MOST AREAS WILL SEE WINDS DECREASE THIS
EVENING AND OVERNIGHT, ALTHOUGH WINDS WILL LIKELY REMAIN ELEVATED
NEAR KDAG THROUGH THE NIGHT. ANOTHER PERIOD OF GUSTY WINDS IS
EXPECTED THURSDAY AFTERNOON. VFR CONDITIONS WILL PREVAIL THROUGH
THE TAF PERIOD WITH FEW TO SCT CLOUDS WITH BASES AOA 15KFT EXPECTED.
