AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1247 PM PDT WED MAR 11 2026
KEY MESSAGES
* A SIGNIFICANT WARMING TREND IS EXPECTED THROUGH NEXT WEEK, WHICH
WILL INCREASE TEMPERATURES TO NEAR-20 DEGREES ABOVE-NORMAL.
MINOR TO MODERATE HEATRISK WILL DEVELOP NEXT WEEK AND COULD POSE
HEALTH IMPACTS TO ANYONE UNPREPARED FOR THE UNPRECEDENTED HEAT.
DISCUSSION
THROUGH WEDNESDAY.
NOT MUCH CHANGE IN THE FORECAST AND POTENTIAL IMPACTS AS THE MAIN
FOCUS IS THE ANOMALOUSLY WARM TEMPERATURES. RIDGING WILL BUILD IN
THROUGH FRIDAY AND TEMPERATURES WILL RESPOND BY JUMPING 3-5 DEGREES
EACH DAY. BY FRIDAY, HIGH TEMPERATURES WILL CLIMB TO 10-15 ABOVE
NORMAL. A WEAK SHORTWAVE WILL KNOCK DOWN THE AREA OF HIGH PRESSURE
SLIGHTLY LATE FRIDAY THROUGH SUNDAY MORNING, WHICH WILL SLOW THE
WARMING TREND AND KEEP TEMPERATURES STAGNANT (BUT STILL WELL ABOVE
NORMAL) THROUGH THE WEEKEND. NEXT WEEK THOUGH, GOOD AGREEMENT
AMONGST ENSEMBLES THAT A STRONG RIDGE WILL BUILD INTO THE REGION AND
EVEN WARMER TEMPERATURES ARE EXPECTED AS TEMPERATURES REACH 20+
DEGREES ABOVE NORMAL. THERE IS A HIGH CHANCE (80%) FOR HIGH
TEMPERATURES IN LAS VEGAS TO EXCEED 90F STARTING TUESDAY AND
CONTINUING THROUGH THE WEEK. IN DEATH VALLEY AND THE COLORADO RIVER
VALLEY, THE EXPECTATION IS FOR HIGH TEMPERATURE TO EXCEED 100F
STARTING TUESDAY OR WEDNESDAY. THESE ANOMALOUS TEMPERATURES WILL
YIELD MINOR-TO-MODERATE HEATRISK (LEVELS 1 AND 2 OF 4) ACROSS THE
REGION, IMPACTING ANYONE WITHOUT ACCESS TO ADEQUATE COOLING OR
HYDRATION AND ARE HEAT SENSITIVE INDIVIDUALS. IN ADDITION- NEXT WEEK
IS SPRING BREAK FOR MANY LOCATIONS- IF YOU HAVE OUTDOOR PLANS THIS
WEEKEND OR NEXT WEEK, OR IF YOU ARE VISITING THE SOUTHWEST US FROM A
COOLER CLIMATE, PREPARE FOR SUMMERTIME HEAT. MAKE SURE TO REMAIN
HYDRATED, WEAR LIGHT WEIGHT CLOTHING, AND DON'T FORGET THE SUNSCREEN
IF YOU ARE HEADED OUTDOORS.
