AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
950 AM PDT SUN JUN 29 2025
KEY MESSAGES
* SLOW WARMING TREND CONTINUES INTO EARLY NEXT WEEK. HOTTEST
TEMPERATURES WILL BE ON MONDAY AND TUESDAY. TEMPERATURES COOL TO
NEAR NORMAL BY MIDWEEK.
* INCREASING MOISTURE WILL BRING A SLIGHT CHANCE FOR THUNDERSTORM
ACTIVITY NEXT WEEK, MAINLY FOR MOHAVE COUNTY, WITH MUCH OF THE
REST OF THE AREA REMAINING DRY.
DISCUSSION
THROUGH THE END OF NEXT WEEK.
TYPICAL SUMMER HEAT WILL PREVAIL THROUGH EARLY NEXT WEEK AS HIGH
PRESSURE BUILDS ACROSS THE AREA. WITH HEIGHTS SLOWLY RISING,
TEMPERATURES WILL GRADUALLY CLIMB EACH DAY, RISING 3-7 DEGREES
ABOVE NORMAL BY MONDAY AND TUESDAY. DESPITE BEING WARMER THAN
THE DAILY AVERAGES, IT'S STILL PRETTY TYPICAL HEAT FOR LATE JUNE
AND HEAT RISK LARGELY REMAINS IN THE MODERATE CATEGORY. A FEW
POCKETS OF MAJOR HEAT RISK DEVELOP IN PARTS OF MOHAVE COUNTY AND
THE COLORADO RIVER MONDAY AND TUESDAY, BUT REMAIN TOO BRIEF AND
SPOTTY IN NATURE TO JUSTIFY ANY HEAT PRODUCTS. AS MOISTURE PUSHES
INTO ARIZONA MIDWEEK AND HEIGHTS BEGIN TO FALL AS A LOW PRESSURE
SYSTEM OFFSHORE APPROACHES, TEMPERATURES WILL MODERATE TUESDAY
ONWARD AND RETURN TO NEAR NORMAL VALUES.
MEANWHILE, AS THE FOUR CORNERS HIGH ORIENTS ITSELF IN A MORE
FAVORED LOCATION FOR MOISTURE ADVECTION, ALONG WITH A WEAK LOW
OVER SOUTHERN CALIFORNIA STRENGTHENING THE SOUTHERLY FLOW, EXPECT
INCREASING THUNDERSTORM ACTIVITY ACROSS NORTHWEST ARIZONA TUESDAY
ONWARD. A FAIRLY SHARP CONTRAST TO DRIER CONDITIONS ARE EXPECTED
FURTHER WEST THANKS TO A SLIGHT SOUTHWESTERLY COMPONENT OF THE
FLOW ADVECTING DRIER AIR INTO THE REGION, BUT STORM CHANCES LOOK
TO SPREAD INTO THE EASTERN MOJAVE DESERT AND PERHAPS LINCOLN
COUNTY WEDNESDAY AND THURSDAY. MAIN CONCERNS WILL BE THE POTENTIAL
FOR SOME DRY LIGHTNING INITIALLY, FOLLOWED BY MORE TYPICAL SUMMER
LIKE DOWNPOURS AND GUSTY WINDS MIDWEEK ONWARD.
