1035 PM PDT THU JUN 11 2026
KEY MESSAGES
* HOTTER THAN NORMAL TEMPERATURES WILL CONTINUE THROUGH THE FORECAST
PERIOD.
* MOISTURE WILL INCREASE THIS WEEKEND LEADING TO A SLIGHT CHANCE
OF SHOWERS AND THUNDERSTORMS OVER PORTIONS OF EASTERN NEVADA AND
WESTERN ARIZONA.
DISCUSSION
TODAY THROUGH WEDNESDAY.
HOTTER THAN NORMAL TEMPERATURES WILL CONTINUE THROUGH THE FORECAST
PERIOD. TEMPERATURES THIS AFTERNOON WILL TOP OUT AROUND 4 TO 8
DEGREES ABOVE NORMAL, AND WILL WARM A DEGREE OR TWO ON TOP OF THAT
FROM TODAY TO TOMORROW. THIS WILL RESULT IN WIDESPREAD MODERATE
HEATRISK (LEVEL 2 OF 4) ON FRIDAY, WITH POCKETS OF MAJOR HEATRISK
(LEVEL 3 OF 4) FOR PORTIONS OF THE COLORADO RIVER VALLEY, LAS VEGAS
VALLEY, AMARGOSA VALLEY, AND DEATH VALLEY NATIONAL PARK.
TEMPERATURES WILL HOLD STEADY OVER THE WEEKEND, FLUCTUATING A DEGREE
OR TWO FROM DAY TO DAY BEFORE TAKING OFF EARLY NEXT WEEK. THIS WILL
ALLOW FOR WIDESPREAD MODERATE HEATRISK TO PERSIST ACROSS THE REGION
THROUGH THE WEEKEND WITH POCKETS OF MAJOR HEATRISK PERSISTING IN THE
PREVIOUSLY MENTIONED AREAS. AS TEMPERATURES TAKE OFF NEXT WEEK,
HEATRISK WILL ALSO INCREASE WITH MAJOR HEATRISK BECOMING MORE
WIDESPREAD AND THE POTENTIAL FOR EXTREME HEATRISK (LEVEL 4 OF 4) TO
BEGIN POPPING UP IN SOME AREAS.
CURRENT WATER VAPOR SATELLITE IMAGERY SHOWS THE MCV MENTIONED IN
THE PREVIOUS DISCUSSION CONTINUING TO PUSH NORTH ALONG THE GULF
OF CALIFORNIA/BAJA PENINSULA. THIS MOISTURE WILL BEGIN TO CREEP UP
THE COLORADO RIVER VALLEY LATE TOMORROW, SPILLING OVER INTO
NEIGHBORING COUNTIES OVER THE WEEKEND. PRECIPITABLE WATER VALUES
WILL BE AROUND 0.75 TO 1.0 INCHES IN MOHAVE, CLARK, SOUTHEASTERN
SAN BERNARDINO, AND EASTERN LINCOLN COUNTIES, WITH LOCALLY HIGHER
PWS IN THE COLORADO RIVER VALLEY. HOWEVER, THE PRESENCE OF
ANOMALOUS MOISTURE ALONE IS NOT ENOUGH FOR CONVECTION TO DEVELOP.
WE WILL BE DEPENDENT ON DAYTIME HEATING AS OUR MAIN SOURCE OF
LIFT FOR THE DEVELOPMENT OF SHOWERS AND THUNDERSTORMS, MEANING
AREAS OF HIGHER TERRAIN WILL BE FAVORED FOR THE DEVELOPMENT OF
ISOLATED CONVECTION OVER THE WEEKEND PENDING ANY DECAYING MCVS
DRIFTING INTO OUR FORECAST AREA. IN ADDITION TO THE LACK OF
FORCING, THE LOWER LEVELS OF THE ATMOSPHERE WILL REMAIN RELATIVELY
DRY THROUGH THE WEEKEND AS THIS MOISTURE WILL PREDOMINANTLY BE
LIMITED TO THE MID- LEVELS OF THE ATMOSPHERE. THIS MEANS THAT
VIRGA SHOWERS CAPABLE OF RESULTING IN STRONG GUSTY WINDS AND DRY
LIGHTNING WILL BE POSSIBLE WITH CONVECTION THAT DOES NOT END UP
PRODUCING MODERATE- TO- HEAVY RAIN. CHANCES FOR PRECIPITATION WILL
DECREASE AS WE HEAD INTO NEXT WEEK AND MOISTURE BEGINS TO MOVE
OUT OF THE AREA.
AVIATION...FOR HARRY REID...FOR THE 00Z FORECAST PACKAGE
WINDS ARE EXPECTED TO REMAIN LESS THAN 8 KNOTS INTO THIS EVENING
WITH WINDS VARYING FROM NORTHEAST TO SOUTHEAST, BEFORE SETTLING TO
THE SOUTHWEST AFTER SUNSET. WE WILL CONTINUE TO SEE HAZY CONDITIONS
THROUGH SUNSET WITH VISIBILITY GENERALLY REMAINING ABOVE 6SM.
IMPROVEMENT IS EXPECTED OVERNIGHT. TEMPERATURES WILL REMAIN 100 DEG
OR ABOVE THROUGH 03-04Z BEFORE DROPPING. NO OPERATIONALLY
SIGNIFICANT CLOUD COVER, ALTHOUGH WE WILL START TO SEE SOME
INCREASING HIGH CLOUDS FROM THE SOUTH LATE THIS EVENING. HIGH
TEMPERATURE FRIDAY IS 108F, WITH BEST CHANCES OF 100F OR GREATER
BETWEEN 19Z AND 04Z.
FOR THE REST OF SOUTHERN NEVADA, NORTHWEST ARIZONA AND SOUTHEAST
CALIFORNIA...FOR THE 06Z FORECAST PACKAGE...WINDS WILL GENERALLY
FALL BELOW 10 KNOTS OVER MOST AREAS AFTER SUNSET WITH TYPICAL
DIURNAL DIRECTIONS. WINDS AT KDAG WILL REMAIN GUSTY OUT OF THE WEST
THROUGH MUCH OF THE OVERNIGHT PERIOD WITH SPEEDS BETWEEN 10-20 KNOTS
WITH OCCASIONAL GUSTS TO 25 KNOTS. WILL NEED TO WATCH FOR THE
POTENTIAL OF GUSTY OUTFLOW WINDS AT KBIH FRIDAY AFTERNOON.
THUNDERSTORMS ARE NOT EXPECTED AT THE TERMINAL, BUT SOME WIND
IMPACTS ARE POSSIBLE. CLOUD OR WEATHER IMPACTS ARE NOT EXPECTED OVER
THE REMAINING TAF SITES.
