NATIONAL WEATHER SERVICE LAS VEGAS NV
336 PM PDT MON MAR 16 2026
KEY MESSAGES
* BREEZY NORTH WINDS CONTINUE THIS AFTERNOON ACROSS LAKE MOHAVE AND
LAKE HAVASU, RESULTING IN HAZARDOUS BOATING CONDITIONS.
* EXTREME EARLY-SEASON HEAT EXPECTED THROUGH THIS WEEKEND, WITH
WIDESPREAD EXTREME HEAT WARNINGS AND HEAT ADVISORIES IN EFFECT.
DISCUSSION
TODAY THROUGH SUNDAY.
GUSTY NORTH WINDS WILL CONTINUE THIS AFTERNOON ALONG THE COLORADO
RIVER VALLEY, WITH SUSTAINED WINDS BETWEEN 15 AND 25 MPH AND GUSTS
TO 40 MPH. THIS WILL RESULT IN 1 TO 3 FT WAVES ON LAKE MOHAVE AND
LAKE HAVASU, WHICH WILL CREATE HAZARDOUS BOATING CONDITIONS FOR
SMALL CRAFT. SPEEDS WILL GRADUALLY DIMINISH OVER THE NEXT FEW
DAYS.
A RIDGE OF HIGH PRESSURE WILL CONTINUE TO BUILD OVER THE
SOUTHEASTERN PACIFIC OCEAN AS IT SLOWLY MEANDERS INLAND THROUGH
THE THE WEEK. AS A RESULT, TEMPERATURES WILL STEADILY CLIMB EACH
DAY, WITH MANY LOCATIONS OBSERVING AFTERNOON TEMPERATURES NEAR 30
DEGREES ABOVE-NORMAL. EXTREME HEAT WATCHES WERE UPGRADED TO
EXTREME HEAT WARNINGS THROUGH THE WEEKEND, WITH THE ADDITION OF
NORTHERN CLARK AND NORTHERN MOHAVE COUNTIES. THE SOUTHERN GREAT
BASIN INCLUDING THE OWENS VALLEY WERE ADDED TO A HEAT ADVISORY.
HEAT ADVISORY ZONES FALL OFF ON SATURDAY, AS THE CENTER OF THE LOW
SHIFTS SOUTHWARD OVER THE BAJA, WHILE THE EXTREME HEAT WARNING
GOES THROUGH SUNDAY. TIMING OF THESE HEADLINES (WHETHER OR NOT TO
EXTEND) WILL BE REEVALUATED AS WE MOVE THROUGH THE WEEK. WHILE
FORECAST TEMPERATURES ON THEIR OWN MAY NOT SEEM "EXTREME", WE ARE
FORECASTING BREAKS OR TIES TO DAILY RECORDS, MONTHLY RECORDS, AND
STATE-WIDE MONTHLY RECORDS ACROSS THE REGION. TO PUT THIS HEAT
FURTHER INTO PERSPECTIVE, LAS VEGAS'S EARLIEST 100-DEGREE DAY ON
RECORD IS MAY 1ST. LAS VEGAS HAS NEVER OBSERVED 100 DEGREES IN
APRIL, YET HAS A 50 PERCENT CHANCE OF 100 ON FRIDAY (MARCH 20TH)
AND A 40 PERCENT CHANCE ON SATURDAY (MARCH 21ST). THESE
TEMPERATURES ARE NOT ONLY ANOMALOUS TO REGIONAL LOCALS, BUT
ESPECIALLY TO TOURISTS WHO ARE VISITING FROM COOLER CLIMATES, AS
MUCH OF THE EAST COAST EXPERIENCES WINTER WEATHER THIS WEEK.
SPRING BREAK IS IN SESSION FOR LOCALS AND TOURISTS ALIKE,
RESULTING IN INCREASED OUTDOOR RECREATION ACROSS OUR FORECAST
AREA. TO REDUCE HEAT-RELATED IMPACTS, FOLKS ARE ENCOURAGED TO
HYDRATE FREQUENTLY, EAT LIGHTER MEALS, WEAR SUNSCREEN, AND AVOID
CONSUMING CAFFEINE, ALCOHOL, OR OTHER DRUGS WHILE OUT IN THE HEAT.
