SOUTHEAST ARIZONA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
215 AM MST FRI MAR 17 2000

SYNOPSIS...A VERY WEAK WEATHER FRONT WILL SLIDE SOUTHEAST ACROSS 
ARIZONA TODAY. ONLY A FEW HIGH CLOUDS AT TIMES WILL BE SEEN IN 
SOUTHERN ARIZONA FROM THIS FRONT. TEMPERATURES WILL REMAIN UNCHANGED 
WITH AFTERNOON READINGS 5 TO 10 DEGREES ABOVE NORMAL FOR THIS TIME 
OF YEAR. ANOTHER WEAK PACIFIC WEATHER FRONT WILL HEAD TOWARD 
SOUTHERN ARIZONA EARLY NEXT WEEK BUT THIS STORM IS ONLY EXPECTED TO 
BRING A FEW SHOWERS TO THE EASTERN MOUNTAINS AND A FEW CLOUDS TO THE 
REMAINDER OF SOUTHERN ARIZONA.

DISCUSSION...WEAK SHORT WAVE HEADING ACROSS ARIZONA TODAY HAS HIGH 
CLOUDS WITH IT AND THAT IS ABOUT IT. SOME UPWARD VERTICAL MOTION 
WILL MAINTAIN ITSELF AS THE TROF MOVES THROUGH BUT LIMITED MOISTURE 
WILL PREVENT MUCH MORE THAN A FEW HIGH CLOUDS AT TIMES. ANOTHER 
SHORT WAVE WILL HEAD OUR WAY LATE IN THE WEEKEND BUT THIS SYSTEM 
ALSO EXPECTED TO BE ON THE DRY SIDE FOR SOUTHERN ARIZONA. 
TEMPERATURES 5 TO 10 DEGREES ABOVE NORMAL AND LOOK LIKE THEY WILL 
REMAIN THAT WAY INTO THE WEEKEND. PROBABLY SOME COOLING BEGINNING OF 
THE WEEK AS THE NORTHWEST FLOW INCREASES A BIT EARLY NEXT WEEK. 
CURRENT FORECAST HAS THIS ALL WELL IN HAND SO NO CHANGES.    PRF
 
.TWC...NONE.
