DISCUSSION
A STRONG WARMING TREND WILL OCCUR THROUGH EARLY
NEXT WEEK, WITH HIGH TEMPERATURES WARMING TO 10-15 DEGREES ABOVE
NORMAL SUNDAY AND MONDAY. HIGH TEMPERATURES WILL THEN LOWER SEVERAL
DEGREES MID TO LATE NEXT WEEK, BUT STILL REMAIN ABOVE NORMAL. MIN
RELATIVE HUMIDITY VALUES THROUGH THE MIDDLE OF NEXT WEEK WILL
GENERALLY BE IN THE 6-15 PERCENT RANGE IN THE VALLEYS AND 12-22
PERCENT IN THE MOUNTAINS. 20-FOOT WINDS WILL BE 15 MPH OR LESS
THROUGH THIS WEEKEND, WITH TYPICAL AFTERNOON/EARLY EVENING GUSTINESS
TO AROUND 25 MPH DUE TO STRONG SURFACE HEATING. THE EXCEPTION WILL
BE IN THE UPPER GILA RIVER VALLEY INCLUDING SAFFORD, WHERE NORTHWEST
WINDS OF 15-20 MPH AND GUSTS TO 30-35 MPH WILL OCCUR THROUGH EARLY
THIS EVENING AND THEN AGAIN SATURDAY AFTERNOON/EVENING. GUSTY
EASTERLY WINDS OF 15 TO 25 MPH ARE EXPECTED IN GRAHAM/COCHISE
COUNTIES MONDAY MORNING, TAPERING OFF MONDAY AFTERNOON. OTHERWISE,
20-FOOT WINDS MAINLY LESS THAN 15 MPH THROUGH MUCH OF NEXT WEEK.
THERE IS THE POTENTIAL FOR MID LEVEL MOISTURE TO MOVE INTO THE AREA
LATE MONDAY THROUGH THURSDAY OF NEXT WEEK. IF THIS OCCURS, IT WOULD
RESULT IN A SLIGHT CHANCE OF DRY THUNDERSTORMS AND/OR GUSTY OUTFLOW
WINDS.
