KEY MESSAGES
* DANGEROUS TEMPERATURES WILL CONTINUE THROUGH MONDAY ACROSS THE
MOJAVE DESERT.
* MONSOONAL MOISTURE REMAINS IN PLACE OVER THE REGION, BUT DAILY
STORM COVERAGE WILL DECREASE AS WE HEAD INTO THE WEEKEND.
DISCUSSION
THROUGH THURSDAY.
TEMPERATURES WILL CONTINUE TO INCREASE ACROSS SOUTHERN NEVADA,
SOUTHEASTERN CALIFORNIA, AND NORTHWESTERN ARIZONA AS HIGH PRESSURE
CONTINUES TO BUILD OVER THE REGION. THIS RIDGE WILL PERSIST THROUGH
THE WEEKEND INTO NEXT WEEK, ENABLING HOTTER THAN NORMAL TEMPERATURES
TO CONTINUE INTO EARLY NEXT WEEK. AFTERNOON HIGH TEMPERATURES AND
OVERNIGHT LOW TEMPERATURES WILL CONTINUE TO RUN AROUND 5 TO 10
DEGREES ABOVE NORMAL FOR MOST OF THE AREA. IN PLACES LIKE LAS VEGAS
AND DEATH VALLEY, THIS MEANS LITTLE-TO-NO OVERNIGHT RELIEF AS LOW
TEMPERATURES WILL BE 90+ AND 100+ DEGREES, RESPECTIVELY. WIDESPREAD
MAJOR HEATRISK (LEVEL 3 OF 4) WITH POCKETS OF EXTREME HEATRISK
(LEVEL 4 OF 4) IN THE COLORADO RIVER VALLEY, AMARGOSA VALLEY, AND
GOLDEN VALLEY AREAS WILL CONTINUE THROUGH THE WEEKEND AND INTO NEXT
WEEK.
WE WILL SEE A SLIGHT UPTICK IN MOISTURE TODAY AS UPPER-LEVEL FLOW
BECOMES MORE SOUTHEASTERLY, HELPING BRING SLIGHTLY HIGHER PWATS
TO THE AREA TODAY. THIS SLIGHT INCREASE IN MOISTURE WILL GIVE US
THE POTENTIAL FOR SLIGHTLY MORE CONVECTIVE COVERAGE TODAY. THE
BEST CHANCES FOR PRECIPITATION TODAY (20 TO 40%) WILL BE IN THE
HIGHER TERRAIN OF NORTHWESTERN ARIZONA, SOUTHERN NEVADA, THE
EASTERN SIERRA AND THE GREAT BASIN. GUSTY OUTFLOW WINDS AND FLASH
FLOODING WILL CONTINUE TO BE THE GREATEST THREATS WITH ANY STORMS
THAT DEVELOP. MONSOONAL MOISTURE WILL LINGER INTO NEXT WEEK;
HOWEVER, CONVECTIVE COVERAGE WILL BE LIMITED TO THE HIGHER TERRAIN
IN THE EASTERN PORTIONS OF OUR FORECAST AREA.
