DISCUSSION
THROUGH NEXT WEEKEND.
MOSTLY SUNNY AND WARM CONDITIONS PREVAIL ACROSS THE REGION THIS
AFTERNOON. WE ARE EXPECTING A FEW VERY LIGHT SHOWERS TO DEVELOP
WITH THE AFTERNOON HEATING ACROSS THE SIERRA REGION AS WELL AS THE
ARIZONA STRIP, THOUGH NONE OF THE SHOWER ACTIVITY IS EXPECTED TO
BE OF MUCH IMPACT. ON MONDAY, A WEAK LOW PRESSURE CENTER WILL MOVE
INTO ARIZONA WITH A FEW LIGHT SHOWERS AGAIN EXPECTED ACROSS
NORTHWEST ARIZONA, MAINLY EAST AND NORTH OF KINGMAN AND ACROSS THE
ARIZONA STRIP. ELSEWHERE, DRY AND WARM CONDITIONS WILL CONTINUE
FOR MEMORIAL DAY.
BY TUESDAY, A FAIRLY DEEP LOW PRESSURE SYSTEM WILL DROP INTO THE
GREAT BASIN FROM THE PACNW. THE APPROACH OF THIS LOW AND THE
TIGHTENING PRESSURE GRADIENT WILL LEAD TO GUSTY CONDITIONS ACROSS
MUCH OF THE REGION, ESPECIALLY THE WESTERN MOJAVE DESERT AND PARTS
OF SOUTHERN NEVADA. IN COORDINATION WITH OUR NEIGHBORING CALIFORNIA
OFFICES, WENT AHEAD AND ISSUED A WIND ADVISORY FOR THE WESTERN
MOJAVE DESERT NEAR BARSTOW FOR TUE-THU, AND ADDITIONAL WIND
HEADLINES WILL LIKELY BE REQUIRED FOR AREAS FURTHER EAST AS
CONFIDENCE IN THE TIMING DETAILS INCREASES. IN ADDITION TO THE
GUSTY WINDS, TEMPERATURES WILL BEGIN TO DECLINE TUESDAY, AND
ESPECIALLY WEDNESDAY-THURSDAY AS THE LOW REMAINS IN CLOSE
PROXIMITY TO THE REGION AND SUBDUES HEIGHTS. AS THE LOW WEAKENS
LATE IN THE WEEK, TEMPERATURES WILL MODERATE AND RETURN TO ABOVE
NORMAL BY THE WEEKEND.
IN ADDITION TO THE GUSTY WINDS AND COOLER TEMPS, A FEW SHOWERS ARE
EXPECTED ACROSS THE SOUTHERN GREAT BASIN AND SIERRA REGION
WEDNESDAY AND THURSDAY AS THE LOW SITS NEARLY OVERHEAD.
PRECIPITATION AMOUNTS ARE GENERALLY EXPECTED TO BE LIGHT, BUT A
FEW STRONGER CORES COULD PRODUCE LIGHTNING AND BRIEF DOWNPOURS
GIVEN THE STEEP LAPSE RATES AND COOL AIR ALOFT. THE LOW WILL
WEAKEN BY THE WEEKEND WITH PRECIPITATION CHANCES ENDING.
AVIATION...FOR HARRY REID...FOR THE 18Z FORECAST PACKAGE

WILL VEER TO THE SOUTHEAST, BECOMING ELEVATED AND AT LEAST
INTERMITTENTLY GUSTY THIS AFTERNOON THROUGH SUNSET. SUSTAINED
SPEEDS AROUND 12-15KT ARE EXPECTED, ALONG WITH GUSTS TO AROUND
20KT. THERE IS MODERATE TO HIGH CONFIDENCE THAT GUSTS WILL REMAIN
BELOW 25KT. AFTER SUNSET, WINDS SHIFT TO THE SOUTHWEST, BECOMING
LIGHT OVERNIGHT. BY LATE MORNING MONDAY, WINDS WILL SHIFT TO THE
SOUTH/SOUTH-SOUTHEAST, GUSTING TO AROUND 15-18KT THEREAFTER
THROUGH THE END OF THE FORECAST PERIOD. VFR CONDITIONS WILL

PERCENT CHANCE OF SHOWERS/VIRGA OVER THE SIERRA AND ACROSS
