HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE HUNTSVILLE AL
130 PM CDT WED AUG 27 2003

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH ALABAMA.

.DAY ONE...(THIS AFTERNOON AND TONIGHT)...

THE PROBABILITY OF WIDESPREAD HAZARDOUS WEATHER IS LOW.

SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE DEVELOPING ACROSS
NORTH ALABAMA THIS AFTERNOON. DUE TO WEAK WINDS THROUGHOUT THE
ATMOSPHERE...ANY THUNDERSTORMS THAT FORM WILL BE SLOW MOVERS. WHILE
PROLONGED PERIODS OF HEAVY RAIN ARE POSSIBLE...WIDESPREAD FLASH
FLOODING IS NOT EXPECTED. FREQUENT CLOUD TO GROUND LIGHTNING...ALONG
WITH WIND GUSTS TO 35 MPH AND SMALL HAIL...ARE ALSO POTENTIAL THREATS
FROM THUNDERSTORMS THIS AFTERNOON.

HOWEVER...IT SHOULD BE NOTED THAT MANY AREAS WILL RECEIVE NO RAINFALL
AT ALL. AREAS THAT DO NOT EXPERIENCE RAIN WILL SEE ANOTHER PARTLY
SUNNY AND HOT AFTERNOON. TEMPERATURES REACHING INTO THE LOWER 90S...
COUPLED WITH TYPICAL SUMMERTIME HUMIDITY...WILL PUSH HEAT INDICES TO
NEAR 100 DEGREES. ANYONE PARTICIPATING IN OUTDOOR ACTIVITIES THIS
AFTERNOON SHOULD REMEMBER TO TAKE FREQUENT BREAKS AND DRINK PLENTY OF
WATER.

.DAYS TWO THROUGH SEVEN...(THURSDAY THROUGH TUESDAY)...

THE PROBABILITY OF WIDESPREAD HAZARDOUS WEATHER IS LOW.

A RETURN OF LOW-LEVEL MOISTURE IS EXPECTED OVER NORTHERN ALABAMA
FOR THE LATER HALF OF THE WEEK. INCREASED ATMOSPHERIC INSTABILITY
DUE TO DAYTIME HEATING...WILL CAUSE ISOLATED SHOWERS AND
THUNDERSTORMS TO DEVELOP. THE MID AFTERNOON TO EARLY EVENING HOURS IS
THE MOST LIKELY TIME FOR THUNDERSTORM FORMATION.

RAIN CHANCES WILL INCREASE OVER THE LABOR DAY WEEKEND...AS A COLD
FRONT APPROACHES THE REGION FROM THE MIDWEST. A TROPICAL SYSTEM OVER
THE WESTERN CARIBBEAN WILL BE MOVING NORTHWEST THROUGH THE WEEKEND.
IF THIS SYSTEM WAS TO DEVELOP...THIS COULD INCREASE THE CHANCES OF
RAIN ACROSS THE SOUTHEASTERN STATES.

.SPOTTER CALL TO ACTION STATEMENT...

ACTIVATION OF STORM SPOTTERS AND EMERGENCY MANAGEMENT PERSONNEL IS
NOT ANTICIPATED.
