AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1040 AM PDT THU JUL 2 2026
KEY MESSAGES
* DRY CONDITIONS, BREEZY AFTERNOONS, AND GRADUALLY WARMING
TEMPERATURES CONTINUE THROUGH THE MIDDLE OF NEXT WEEK.
DISCUSSION
TODAY THROUGH WEDNESDAY.
THE DESERT SOUTHWEST REMAINS SITUATED BENEATH A BROAD UPPER-LEVEL
TROUGH, WHICH IS CONDUCIVE FOR SHORTWAVE PASSAGES ALONG THE FLOW
ALOFT, RESULTING IN BREEZY AFTERNOONS. EACH AFTERNOON CAN GENERALLY
EXPECT SOUTH-SOUTHWESTERLY WIND GUSTS AROUND 20 MPH, WITH STRONGER
SPEEDS IN THE HIGHER TERRAIN. THESE BREEZES COUPLED WITH DRY
CONDITIONS WILL ELEVATE FIRE DANGER, BUT NOT ENOUGH FOR A FIRE-
RELATED HEADLINE. THAT SAID, AS INDEPENDENCE DAY ACTIVITIES INCREASE
INCLUDING COOKING ON CHARCOAL GRILLS AND USING SAFE-AND-SANE
FIREWORKS, FOLKS ARE ENCOURAGED TO STAY SAFE AND ENSURE THERE ARE
PLENTY OF WATER SOURCES NEARBY FOR ANY POTENTIAL FIRE STARTS. OVER
THE WEEKEND, THE AFOREMENTIONED TROUGH WILL FINALLY WEAKEN AND PUSH
EAST, ALLOWING THE NORTHERN MEXICO / FOUR CORNERS HIGH PRESSURE TO
RETURN TO THE REGION. TEMPERATURES WILL CONTINUE TO GRADUALLY
INCREASE THROUGH THE FORECAST PERIOD, WITH WIDESPREAD MODERATE HEAT
RISK (LEVEL 2 OF 4) BY MONDAY. FOR LAS VEGAS, THERE IS A 25 PERCENT
CHANCE OF THE FIRST 110F OF THE YEAR ON TUESDAY AND A 38 PERCENT
CHANCE ON WEDNESDAY.
AVIATION...FOR HARRY REID...FOR THE 18Z FORECAST PACKAGE
WINDS
WILL GENERALLY FOLLOW DAILY DIRECTIONAL PATTERNS, WITH SPEEDS
EXPECTED TO INCREASE ABOVE 10 KTS AROUND AND AFTER 20Z FROM THE
SOUTH. EARLY TO MID-AFTERNOON, WINDS SHIFT TO THE SOUTH SOUTHWEST,
INCREASING TO AROUND 10-15KT WITH GUSTS TO 20-25KT EXPECTED
THEREAFTER THROUGH SUNSET. WINDS AND GUSTS WILL DIMINISH QUICKLY
AFTER SUNSET, REMAINING SOUTHWESTERLY WITH SPEEDS UNDER 8KT
OVERNIGHT. VFR CONDITIONS WILL PREVAIL, THOUGH SLANTWISE VISIBILITY
REDUCTIONS DUE TO WILDFIRE SMOKE ALONG THE MORMON MESA CORRIDOR WILL
PERSIST.
FOR THE REST OF SOUTHERN NEVADA, NORTHWEST ARIZONA AND SOUTHEAST
CALIFORNIA...FOR THE 18Z FORECAST PACKAGE...WINDS GENERALLY FOLLOW
TYPICAL DIRECTIONAL PATTERNS WITH SOME VARIABILITY THROUGH EARLY
AFTERNOON. EXPECT A WIND SHIFT TO THE SOUTH AND SOUTHWEST,
INCREASING TO AROUND 10-15KT WITH GUSTS TO 20-25KT LIKELY THROUGH
SUNSET WHEN WINDS AND GUSTS QUICKLY DIMINISH. AN EXCEPTION TO THIS
WILL BE ACROSS THE WESTERN MOJAVE, INCLUDING KDAG, WHERE WINDS
GENERALLY REMAIN WESTERLY TO SOUTHWESTERLY FOR THE DURATION, WITH
SPEEDS AROUND 10-15KT AND GUSTS PEAKING AROUND 25-30KT LATER THIS
EVENING. OTHERWISE, VFR CONDITIONS WILL PREVAIL WITH NO OPERATIONAL
CLOUD COVER EXPECTED, THOUGH SLANTWISE VISIBILITY REDUCTIONS DUE TO
WILDFIRE SMOKE CAN BE EXPECTED AT TIMES.
