KEY MESSAGES
* ANOTHER COUPLE DAYS OF BELOW-NORMAL TEMPERATURES BEFORE THE REGION
WARMS UP THROUGH THE WEEK.
* MONSOONAL MOISTURE INCREASES IN ARIZONA MID-TO-LATE WEEK, WITH
BEST CHANCES OF PRECIPITATION ACROSS MOHAVE COUNTY.
DISCUSSION
TODAY THROUGH SATURDAY.
DRY SOUTHWEST FLOW ALOFT WILL CONTINUE THROUGH THE REMAINDER OF THE
WEEKEND INTO THE START OF NEXT WEEK, RESULTING IN PERSISTENT BREEZY
AFTERNOONS. IN ADDITION TO SOUTHWEST BREEZES BETWEEN 15 AND 25 MPH,
THE TROUGH ACROSS THE WESTERN CONUS HAS ALLOWED HEIGHTS ALOFT TO
DROP, RESULTING IN BELOW-NORMAL TEMPERATURES. THIS TROUGH WILL
REMAIN SITUATED ACROSS THE WESTERN CONUS, BUT A RIDGE OF HIGH
PRESSURE ACROSS THE SOUTHERN CONUS WILL BEGIN TO RETROGRADE WESTWARD
THROUGH THE WORK WEEK. THE RIDGE'S WESTWARD PROGRESSION WILL ALLOW
HEIGHTS TO RISE OVER THE DESERT SOUTHWEST, RESULTING IN AT-OR-ABOVE
NORMAL TEMPERATURES RETURNING TO THE REGION AS SOON AS MONDAY.
THE RETROGRADING OF THIS SOUTHERN CONUS HIGH PRESSURE WILL ALSO
RESULT IN AN INFLUX OF MONSOONAL MOISTURE UP THE COLORADO RIVER
VALLEY. HOWEVER, THE AFOREMENTIONED WESTERN CONUS TROUGH WILL
CONTEND WITH THE RIDGE'S WESTWARD PROGRESSION, WORKING TO PREVENT
MOISTURE FROM MAKING IT MUCH FURTHER WEST THAN ARIZONA. PWATS WILL
INCREASE TO AROUND 0.50" ACROSS OUR FAR SOUTHERN ZONES ON TUESDAY,
SURGING TO AROUND 0.75" ON THURSDAY IN THE LOWER COLORADO RIVER
VALLEY. THIS MOISTURE LINGERS THROUGH FRIDAY BEFORE RAPIDLY
RETREATING. AS A RESULT, SLIGHT POPS (15-30 PERCENT) EXIST FOR
MOHAVE COUNTY TUESDAY THROUGH SATURDAY. OF NOTE, DUE TO THE DRY LOW-
LEVELS AND MODEST MOISTURE FLUX ACROSS NORTHERN ARIZONA, FORECAST
RAINFALL TOTALS REMAIN LESS THAN 0.05" ON ANY GIVEN DAY, MAKING
STRONG GUSTY WIND AND FREQUENT LIGHTNING THE PRIMARY HAZARDS NEXT
WEEK. ELSEWHERE, EXPECT DRY CONDITIONS AND MOSTLY SUNNY SKIES.
