NORTHERN ARIZONA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
845 AM MST FRI SEP 5 1997

TODAY WON'T BE A QUIET DAY EXACTLY...BUT IT WILL BE MORE ON THE CALM
SIDE ACROSS MOST OF THE NORTHLAND THAN IT HAS BEEN.

SFC DEWPTS THIS MORNING ARE RUNNING A FEW DEGREES LOWER THAN
YESTERDAY. PERHAPS INDICATIVE OF A SOMEWHAT MORE STABLE TREND THAT
WILL TEND TO RESULT IN A MORE DIURNAL PATTERN OF CONVECTION. THE
MORNING FGZ SOUNDING SHOWS A COUPLE INVERSIONS...THE FIRST AND WEAKER
ONE AT 600 MB. THE SECOND REVEALS SUBSIDENCE NEAR 520 MB ASSOCIATED
WITH THE STRONGER CAP. PROGGED H7 MSO THTE IS EVEN NOTICEABLY LOWER
AROUND THE NORTHLAND THROUGH TODAY. THIS AFTERNOON'S WX SHOULD BE
MARKED BY TS OVER THE HIGH COUNTRY WITH LITTLE EXPECTATION FOR
REACHING SEVERE LEVELS. SINGLE CELL PULSE-TYPE STORMS THAT DON'T
PERSIST ALL THAT LONG SHOULD BE THE RULE TODAY. EXCEPT FOR THE
KAIBAB...IT LOOKS LIKE THAT WILL BE THE RELATIVE HOTSPOT FOR THIS
AFTN IN THE FLG CWFA.

AS FOR THE REMAINING PDS...MORE OF THE SAME. GENERAL CONVECTION
MAINLY ALONG THE RIM AND HIGH COUNTRY...ENDING WITHIN HOURS AFTER
SUNSET. TEMP TRENDS LOOK GOOD WITH LITTLE CHANGE IN HIGHS...SLIGHT
INCREASES IF ANY CHANGES. WINDS...NO PROBLEMS EXCEPT NEAR SOME OF THE
STRONGER THUNDERSTORMS. THE LATEST FLG FORECAST LOOKS FINE AS IS...NO
CHANGES THIS MORNING.
