HOTTER THAN NORMAL TEMPERATURES WILL CONTINUE THROUGH THE FORECAST
PERIOD ACROSS SOUTHERN NEVADA, SOUTHEASTERN CALIFORNIA, AND
NORTHWESTERN ARIZONA AS HIGHER THAN NORMAL 500 MB HEIGHTS PERSIST
ALOFT. HEATRISK WILL PEAK ON FRIDAY AS HIGH TEMPERATURES WILL TOP
OUT AROUND 5 TO 10 DEGREES ABOVE NORMAL, WITH WIDESPREAD MODERATE
HEATRISK (LEVEL 2 OF 4) ACROSS THE REGION AND POCKETS OF MAJOR
HEATRISK (LEVEL 3 OF 4) IN THE COLORADO RIVER VALLEY, DEATH VALLEY,
AND LAS VEGAS VALLEY. TEMPERATURES WILL DECREASE A DEGREE OR TWO
FROM FRIDAY TO SATURDAY, AND WILL HOLD STEADY OVER THE WEEKEND
BEFORE INCREASING AGAIN EARLY NEXT WEEK. EVEN WITH THIS SLIGHT
DECREASE IN TEMPERATURES, POCKETS OF MAJOR HEATRISK WILL LINGER FOR
PORTIONS OF THE AFOREMENTIONED AREAS, WHICH WILL IMPACT ANYONE
WITHOUT ACCESS TO ADEQUATE COOLING AND HYDRATION AS WELL AS THOSE
SPENDING TIME OUTDOORS.
WE ARE CONTINUING TO TRACK A PLUME OF TROPICAL MOISTURE THAT IS
CURRENTLY FORECAST TO MOVE UP THE GULF OF CALIFORNIA AND INTO
ARIZONA OVER THE WEEKEND. CURRENTLY, ENSEMBLES HAVE A LITTLE OVER AN
INCH OF PRECIPITABLE WATER (PW) PUSHING UP THE COLORADO RIVER VALLEY
OVER THE WEEKEND WITH PWS IN LAS VEGAS AROUND 0.75 TO 0.80 INCHES.
IN MOHAVE COUNTY, WHERE THE BEST PRECIPITATION CHANCES ARE, PWS IN
KINGMAN ARE EXPECTED TO BE AROUND 0.90 TO 1.0", WITH VALUES AS HIGH
AS 0.75" AS FAR NORTH AS COLORADO CITY. OVERALL, CHANCES FOR
PRECIPITATION ARE LIMITED TO EASTERN MOHAVE AND EASTERN LINCOLN
COUNTIES OVER THE WEEKEND. OUTSIDE OF THESE AREAS, THE ONLY EVIDENCE
OF THIS MOISTURE WILL LIKELY BE INCREASED CLOUD COVER.
