DISCUSSION
THE EXCESSIVELY HIGH TEMPERATURES WHICH HAVE BEEN IN

MPH CAN BE EXPECTED EACH DAY GOING INTO THE WEEKEND.
THE FORECAST WILL REMAIN DRY FOR THE MAJORITY OF THE REGION THROUGH
THE WEEKEND, BUT MODEL ENSEMBLES ARE BEGINNING TO INDICATE SOME
POTENTIAL FOR MOISTURE WITH PRECIPITABLE WATER VALUES OVER ONE INCH
TO HEAD OUR WAY AS DEEPER SOUTHEAST FLOW DEVELOPS ACROSS NORTHWEST
ARIZONA AND SOUTHERN NEVADA/CALIFORNIA IN RESPONSE TO AN INVERTED
TROUGH MOVING ACROSS CENTRAL SONORA/BAJA AND HIGH PRESSURE BECOMING
CENTERED CLOSER TO THE FOUR CORNERS. NOT A LOT OF CONFIDENCE YET,
