FOR PEOPLE IN THE FOLLOWING LOCATION...

IN NORTHEASTERN ARIZONA

   ...NORTHERN APACHE COUNTY
 
AT 230 PM MST NATIONAL WEATHER SERVICE DOPPLER RADAR CONTINUED TO
INDICATE A SEVERE THUNDERSTORM OVER NORTHERN APACHE COUNTY.  THIS
STORM WAS LOCATED JUST SOUTHWEST OF CHINLE AND WAS MOVING TO THE
NORTHWEST AT AROUND 15 MILES AN HOUR.  THIS STORM IS CAPABLE OF

NAZLINI AND CHINLE WASH. OTHER WASHES IN AND AROUND CHINLE MAY
ALSO BECOME FLOODED. THE STORM MAY ALSO CONTAIN LARGE HAIL.

NORTHERN ARIZONA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
210 PM MST TUE AUG 26 1997

FIRST PERIOD OF THE FORECAST WILL BE BASED ON WSR-88D TRENDS. FLASH
FLOOD WATCH WILL CONTINUE THROUGH 800 PM AS CONVECTION WORKING ALONG
THE DEEPEST MOISTURE PLUME THROUGH CENTRAL AZ CONTINUES TO TRAIN
THROUGH YAVAPAI...WESTERN GILA AND SOUTHERN COCONINO COUNTIES.
ELSEWHERE IN THE WATCH AREA...DAYTIME HEATING IS TRIGGERING SHOWERS
AND THUNDERSTORMS THIS AFTERNOON. DUE TO LOCAL COMPUTER
DIFFICULTIES... GOT A LATE AND SOMEWHAT INCOMPLETE LOOK AT THE 12Z
MODELS. THE ROUTINE COORDINATION CALL HELPED. A DRIER SOUTHWEST FLOW
ALOFT IS PROGGED TO MOVE INTO MAINLY WESTERN SECTIONS OF THE CWFA
THROUGH THURSDAY...THIS HIT ESPECIALLY HARD BY THE AVN. HOWEVER...LOW
LEVELS TO REMAIN MOIST ENOUGH FOR A CONTINUED THREAT FOR TS. WILL
TRIM POPS BACK THROUGH THE PERIOD IN WESTERN ZONES...MAINLY ISOLATED
TO LOW SCATTERED...WITH SCATTERED POPS OVER MUCH OF THE CENTRAL AND
EASTERN ZONES. AS CONVECTIVE ACTIVITY BECOMES MORE DIURNAL IN NATURE
THROUGH THE PERIOD...EXPECT HIGH TEMPS TO WARM TO THEIR POTENTIAL
EACH DAY...UNLIKE MOST PLACES IN CENTRAL AZ TODAY.
