AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
121 PM PDT MON JUL 27 2026
KEY MESSAGES
* HOTTER THAN NORMAL TEMPERATURES WILL CONTINUE THROUGH THE END
FORECAST PERIOD, WITH DANGEROUS AND POTENTIALLY RECORD BREAKING
TEMPERATURES EXPECTED BEGINNING THURSDAY.
* ISOLATED THUNDERSTORM ACTIVITY WILL BE LIMITED TO MOHAVE COUNTY THROUGH
TUESDAY, WITH THINGS DRYING OUT AREA-WIDE DURING THE SECOND HALF OF THE WEEK.
DISCUSSION
THROUGH SUNDAY.
DRY CONDITIONS PREVAIL ACROSS THE REGION THIS AFTERNOON WITH JUST A
SCATTERING OF FAIR WEATHER CUMULUS ACROSS THE SOUTHERN GREAT BASIN AND
NORTHWEST ARIZONA. WE MAY SEE AN ISOLATED SHOWER OR THUNDERSTORM ACROSS
NORTHERN MOHAVE COUNTY BY THIS EVENING BUT IN GENERAL DRIER CONDITIONS
HAVE OVERSPREAD THE AREA WITH LIMITED CONVECTIVE COVERAGE EXPECTED THE
REMAINDER OF THE WEEK GOING FORWARD.
AS THE MOISTURE PROFILE DECREASES, OUR FOCUS WILL SHIFT TO WARMING
TEMPERATURES LATE IN THE WEEK AS A LARGE H500MB RIDGE BUILDS WESTWARD
OUT OF THE SOUTHERN PLAINS. ENSEMBLE AGREEMENT REMAINS HIGH FOR AN
EXPANSIVE 600DM HIGH TO BUILD ACROSS THE SOUTHWEST FRIDAY AND SATURDAY,
WHICH MAY CHALLENGE ALL-TIME AUGUST RECORDS FOR SOME LOCATIONS ACROSS THE
MOJAVE DESERT REGION. THIS WILL ALSO RESULT IN WIDESPREAD HIGH TO EXTREME
HEAT RISK ACROSS MUCH OF THE MIDDLE AND LOWER ELEVATIONS FOR SEVERAL
DAYS IN A ROW. FOR MORE INFORMATION REGARDING EXACTLY WHICH RECORDS ARE IN
JEOPARDY LATER THIS WEEK, SEE THE CLIMATE SECTION BELOW.

CALIFORNIA...FOR THE 18Z FORECAST PACKAGE...BREEZY WINDS ARE
