AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1001 PM PDT SUN JUL 26 2026
KEY MESSAGES
* DANGEROUS TEMPERATURES WILL CONTINUE THROUGH MONDAY ACROSS THE
MOJAVE DESERT, WITH HOTTER THAN NORMAL TEMPERATURES CONTINUING
THROUGH THE REMAINDER OF THE WEEK.
* CONVECTIVE ACTIVITY WILL BE LIMITED TO NORTHWESTERN ARIZONA
THROUGH TUESDAY.
DISCUSSION
THROUGH SATURDAY.
WIDESPREAD MAJOR (LEVEL 3 OF 4) TO EXTREME (LEVEL 4 OF 4) HEATRISK
WILL CONTINUE THROUGH MONDAY AS TEMPERATURES REMAIN AROUND 5 TO 10
DEGREES ABOVE NORMAL. TEMPERATURES WILL REMAIN VERY WARM OVERNIGHT,
WITH LITTLE TO NO RELIEF IN PLACES LIKE LAS VEGAS, LAUGHLIN, LAKE
HAVASU CITY, AND DEATH VALLEY. READINGS WILL FALL A FEW DEGREES
TUESDAY AND WEDNESDAY AS THE RIDGE RESPONSIBLE FOR THE HEAT SHIFTS
TO THE EAST. HOWEVER, THIS RIDGE WILL RETROGRADE WESTWARD LATER IN
THE WEEK, MOVING DIRECTLY OVERHEAD BY THE WEEKEND. THIS WILL RESULT
IN TEMPERATURES INCREASING TO 7 TO 10 DEGREES ABOVE NORMAL BY THE
WEEKEND (THERE IS A 50% CHANCE OF SEEING HIGHS OF 115F IN LAS VEGAS
ON SATURDAY). AS TEMPERATURES CLIMB AGAIN, MAJOR HEATRISK WILL
SPREAD ACROSS MUCH OF THE FORECAST AREA BY FRIDAY, WITH WIDESPREAD
MAJOR-TO-EXTREME HEATRISK EXPECTED BY THE WEEKEND.
A MODEST INCREASE IN MOISTURE, DRIVEN BY OUTFLOW WINDS FROM STORMS
IN CENTRAL ARIZONA YESTERDAY, WILL CONTINUE TO WORK ITS WAY UP THE
COLORADO RIVER VALLEY THIS AFTERNOON, SPILLING INTO FAR SOUTHERN
NEVADA AND NORTHWESTERN ARIZONA. THIS MOISTURE WILL HELP FUEL
ISOLATED AFTERNOON CONVECTION, WITH A 15 TO 20% CHANCE OF
PRECIPITATION IN THE HIGHER TERRAIN OF MOHAVE COUNTY AND THE
COLORADO RIVER VALLEY. CONVECTION CHANCES WILL DIMINISH TOMORROW AS
MOISTURE LEVELS DECREASE. AS THE RIDGE SHIFTS TO THE EAST, WE WILL
SEE A BRIEF PERIOD OF SOUTHEASTERLY WINDS ALOFT, WHICH WILL RESULT
IN A SLIGHT UPTICK IN MOISTURE ON TUESDAY. THIS INCREASE IN MOISTURE
WILL BRING A 15 TO 20% CHANCE OF SHOWERS AND THUNDERSTORMS TO FAR
EASTERN MOHAVE COUNTY TUESDAY AFTERNOON. BEYOND TUESDAY, MOISTURE
LEVELS WILL DECREASE AGAIN ACROSS THE REGION AS THE RIDGE MOVES BACK
OVERHEAD.
