NORTHERN ARIZONA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
1045 AM MST SUN JUL 14 2002

.SYNOPSIS...EXPECT WARM AFTERNOON TEMPERATURES TO PERSIST AS HIGH
PRESSURE MAINTAINS ITS HOLD ON NORTHERN ARIZONA. THE DAILY PATTERN
OF AFTERNOON AND EVENING THUNDERSTORMS WILL CONTINUE WELL INTO THE
COMING WEEK. THE MAJORITY OF SHOWER AND THUNDERSTORM ACTIVITY WILL
BE SOUTH AND WEST OF THE MOGOLLON RIM.

.DISCUSSION...TO FEATURES ON WV A SHORT WAVE ALONG THE NEW MEXICO
BORDER WITH A 2ND MOVING NORTHWARD ALONG THE COLORADO RIVER UP INTO
NORTHWEST PARTS OF THE STATE. CAPE AND MOISTURE VALUES ARE ABOUT
THE SAME TODAY AS YESTERDAY WITH LOWEST VALUES IN THE NORTHEAST DUE
TO THE DRIER AIR IN PLACE OVER THAT AREA. TODAY THE FLOW IS MORE
NORTHWEST IN THE LOW TO MID LEVELS OVER WESTERN SECTIONS OF THE
FORECAST AREA WHICH WOULD LEAD TO OUTFLOW BOUNDARIES PROPAGATING
MORE IN A SOUTHERLY DIRECTION OFF THE RIM. GIVEN THE HIGH CAPE
ENVIRONMENT OVER THIS AREA AND GOOD LOW LEVEL INFLOW...ISOLATED
STRONG STORMS WITH MARGINALLY SEVERE HAIL POSSIBLE. INVERTED V
SOUNDINGS ALONG THE NEW MEXICO BORDER IN THE DRIER AIR WITH WEAK LOW
TO MID LEVEL FLOW...AND STRONGER WINDS ALOFT ASSOCIATED WITH
SHORTWAVE ALONG THE NEW MEXICO BORDER MAY LEAD TO A FEW MICRO BURST
PRODUCING THUNDERSTORMS OUT IN THAT AREA TODAY. LOOKING AT FLAGSTAFF
SOUNDING...HIGH TEMPS WILL NEED TO BE INCREASED 2 TO 3 DEGREES AT A
FEW LOCATIONS. TC
.FGZ...NONE.

HAZARDOUS WEATHER OUTLOOK...CORRECTION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
950 AM MST SUN JUL 14 2002

...SCATTERED SHOWERS AND THUNDERSTORMS EXPECTED TODAY MAINLY FROM
THE CHUSKA MOUNTAINS SOUTH INTO THE WHITE MOUNTAINS AND ALONG AND
SOUTH OF THE MOGOLLON RIM...

DRIER AIR OVER THE NORTHEAST PLATEAUS WILL LIMIT STORM DEVELOP
TODAY. THE ATMOSPHERE WILL BE MORE FAVORABLE FOR STORM DEVELOPMENT
FROM THE CHUSKA MOUNTAINS...SOUTHWARD INTO THE WHITE MOUNTAINS AND
FROM THE MOGOLLON RIM SOUTH AND WEST. EXPECT MORE ACTIVITY OVER THE
KAIBAB PLATEAU AS MOISTURE FROM YESTERDAYS STORMS MOVES NORTHWARD UP
THE COLORADO RIVER BASIN. THESE AREAS WILL SEE ISOLATED STRONGER
STORMS CAPABLE OF PRODUCING GUSTY WINDS...ESPECIALLY ALONG THE NEW
MEXICO BORDER...SMALL HAIL AND RAIN RATES NEAR AN INCH PER HOUR.
STORMS WILL INITIALLY DEVELOP TODAY OVER THE RIM...WHITE MOUNTAINS
AND CHUSKA MOUNTAINS. THREAT FOR FLASH FLOODING TODAY WILL BE
LOW...MAINLY ALONG AND SOUTH OF THE RIM.

BURNED AREA RAIN OUTLOOK...
SMALL AMOUNTS OF RAIN CAN CAUSE FLASH FLOODING IN BURNED OUT AREAS.
SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP NEAR THE
CHEDISKI-RODEO BURN AREA BY THIS AFTERNOON. THE ACTIVITY NEAR THIS
FIRE IS NOT EXPECTED TO BE HEAVY. AS THE SHOWERS MOVE WEST DURING
THE AFTERNOON...THE POTENTIAL FOR HEAVY RAINS OVER THE INDIAN FIRE
BURN AREA NEAR PRESCOTT WILL BE MORE LIKELY.
