DISCUSSION
THROUGH NEXT WEEK.
A WEAK UPPER LEVEL DISTURBANCE NEAR THE MOUTH OF THE COLORADO
RIVER IS SPREADING SOME INCREASED HIGH CLOUD COVER INTO THE
MOJAVE DESERT AND NORTHERN ARIZONA EARLY THIS MORNING. THIS
FEATURE IS OUR FIRST HINT AT A MODEST MOISTURE INCREASE THAT WILL
BRING SOME LOW CHANCES FOR HIGH BASED SHOWERS AND THUNDERSTORMS
STARTING TODAY AND CONTINUING INTO THE WEEKEND. PRECIPITABLE WATER
VALUES BY THIS AFTERNOON WILL CLIMB TO 200% OF NORMAL ALONG AND
SOUTH OF THE I-15 CORRIDOR, AND ENOUGH INSTABILITY WILL BE PRESENT
TO SPARK A FEW WEAK SHOWERS ACROSS THE SIERRA AND NORTHWEST
ARIZONA, AND PERHAPS A FEW OTHER HIGHER TERRAIN POCKETS ACROSS THE
REGION. MOISTURE WILL PEAK ON SATURDAY WITH FAIRLY ROBUST
CONVECTION SUGGESTED ACROSS THE COLORADO PLATEAU BY THIS EVENINGS
CONVECTIVE ALLOWING MODELS, WHICH MAY BRING SOME LIGHT RAINFALL
AND GUSTY WINDS TO MOHAVE COUNTY SATURDAY AFTERNOON. ASIDE FROM
THE SPOTTY SHOWER CHANCES, THE INCREASED MOISTURE AND CLOUD COVER
WILL ALSO HELP TO MODERATE THE HEAT ACROSS THE REGION, THOUGH
ALTERNATIVELY MAY KEEP OVERNIGHT LOWS ELEVATED.
SPEAKING OF HEAT, AS THE MOISTURE PROFILE THINS NEXT WEEK AND
HEIGHTS BEGIN TO CLIMB AGAIN, HEAT WILL BECOME THE DOMINANT
WEATHER CONCERN. IN FACT, MAJOR TO EXTREME HEAT RISK INCREASES IN
COVERAGE MONDAY THROUGH THURSDAY NEXT WEEK AS HIGH TEMPS ACROSS
THE MOJAVE DESERT VALLEYS CLIMB TOWARDS 110, 110S IN THE COLORADO
RIVER VALLEY, NEAR 120 IN THE LOWEST REACHES OF DEATH VALLEY.

THIS EVENING. ISOLATED SHOWERS AND THUNDERSTORMS MAY DEVELOP THIS
AFTERNOON AROUND KBIH AND ACROSS PORTIONS OF NORTHWEST ARIZONA, BUT
THE CHANCE IS LOW (20% OR LESS). IF PRECIPITATION WERE ABLE TO
DEVELOP, THEY COULD PRODUCE SUDDEN GUSTY OUTFLOW WINDS AND
LIGHTNING.
