AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
908 PM PDT WED JUL 22 2026
KEY MESSAGES
* MONSOONAL MOISTURE REMAINS IN PLACE OVER THE REGION, THOUGH DAILY
STORM COVERAGE WILL TEND TO DECREASE LATE IN THE WEEK AND OVER THE
WEEKEND.
* TEMPERATURES WARM THROUGH THE WEEKEND, REACHING DANGEROUS LEVELS
ACROSS THE MOJAVE DESERT THURSDAY THROUGH MONDAY.
DISCUSSION
THROUGH TUESDAY.
MORNING SATELLITE IMAGERY LOOKS QUITE DIFFERENT FROM THIS TIME
YESTERDAY, WITH MOSTLY CLEAR SKIES ACROSS THE AREA. WHILE THERE WILL
BE PLENTY OF SURFACE HEATING TODAY TODAY AND TOMORROW, A SLIGHT
DECREASE IN MOISTURE AND RISING HEIGHTS ALOFT WILL RESULT IN A
REDUCTION OF CONVECTIVE COVERAGE EACH DAY. BEST ODDS (20-40%) REMAIN
ON THE EDGES OF THE CWA (NORTHWESTERN AZ, SOUTHERN GREAT BASIN, AND
SIERRA). ENSEMBLE GUIDANCE INDICATES A STRENGTHENING OF
SOUTHEASTERLY FLOW ALOFT ON FRIDAY, PRODUCING A BRIEF INCREASE IN
MOISTURE AND PRECIPITATION CHANCES, BUT MOISTURE QUICKLY RETURNS TO
CURRENT LEVELS OVER THE WEEKEND AS THE HIGH BUILDS. ANY SHOWER/STORM
ACTIVITY OVER THE WEEKEND SHOULD BE SPARSE. ISOLATED FLASH FLOODING
AND GUSTY OUTFLOW WINDS REMAIN THE PRIMARY CONVECTIVE HAZARDS.
AS THE AFOREMENTIONED HIGH BUILDS, TEMPERATURES ARE FORECAST TO
GRADUALLY BUT STEADILY CLIMB. HEAT LOOKS TO PEAK OVER THE WEEKEND,
BUT WILL BE AT DANGEROUS LEVELS ACROSS THE MOJAVE DESERT THURSDAY
THROUGH MONDAY. FORECAST HIGHS AREN'T RECORD-BREAKING, BUT ENOUGH TO
FEEL OPPRESSIVE WHEN COMBINED WITH THE LINGERING MOISTURE. THE
BIGGER STORY IS THE OVERNIGHT LOWS. FORECAST LOW TEMPERATURES ARE
GENERALLY 85-95 DEGREES ACROSS THE MOJAVE DESERT. UNLESS YOU ARE
LUCKY ENOUGH TO GET AN AFTERNOON SHOWER/STORM, DON'T EXPECT ANY
NOTABLE RELIEF FROM THE HEAT OVER THE NEXT SEVERAL DAYS. WE MAY
START TO SEE A BREAK FROM THE HEAT EARLY/MIDDLE OF NEXT WEEK AS THE
HIGH GETS PUSHED EAST AND MOISTURE TRIES TO INCREASE.
