IMPACTS:

MOST OF THE IMPACTS SO FAR HAVE BEEN LIMITED TO AGRICULTURE IN THE
PLATEAU REGION...HOWEVER THE GROWING SEASON HAS ENDED AND IMPACTS
ARE LIMITED TO WATER SUPPLY AND QUALITY...AS WELL AS FIRE WEATHER.

SOME OF THE SMALLER WATER UTILITY DISTRICTS ARE EXPERIENCING ISSUES
WITH THEIR NORMAL WATER SUPPLY AND HAVE ASKED FOR VOLUNTARY WATER
CONSERVATION.

FIRE WEATHER IMPACTS:

THE RECENT RAINFALL WILL CONTINUE TO INCREASE FUEL MOISTURE
LEVELS...WHICH WILL DECREASE THE LIKELIHOOD OF FIRE DEVELOPMENT.
FURTHERMORE...THE WEATHER PATTERN NOW LOOKS LIKE MORE OF AN ACTIVE
MOIST WINTERTIME REGIME WHEREBY THE SOUTHERN BRANCH OF THE JET
STREAM HAS BECOME MORE ACTIVE. HENCE...FRONTAL AND GULF SYSTEMS ARE
LIKELY TO DEVELOP AND SPREAD MORE BENEFICIAL RAINFALL OVER THE AREA.
IN FACT...RAIN CHANCES WILL RETURN SUNDAY NIGHT THROUGH TUESDAY AS A
SERIES OF FRONTAL SYSTEMS APPROACH AND MOVE THROUGH. RAINFALL TOTALS
LOOK AS THOUGH THEY WILL AVERAGE BETWEEN 1 AND 1 1/2 INCHES OVER THE
NEXT 7 DAYS.

CLIMATE SUMMARY:

PRECIPITATION TOTALS ACROSS MIDDLE TENNESSEE FOR THE MONTH OF
NOVEMBER...GENERALLY AVERAGED BETWEEN 2 AND 5 INCHES OF RAINFALL.
HOWEVER...MOST OF THE RAINFALL OCCURRED AT THE VERY END OF THE
MONTH.  SO FAR FOR DECEMBER...AMOUNTS ARE AVERAGING BETWEEN 1 AND 4
INCHES OF RAINFALL. CERTAINLY...IT IS A GOOD START TO THE MONTH.

TEMPERATURES IN NOVEMBER AVERAGED AROUND 3 TO 6 DEGREES ABOVE
NORMAL. SO FAR FOR DECEMBER...TEMPERATURES ARE RUNNING CLOSE TO
NORMAL.

HYDROLOGICAL SUMMARY:

STREAMFLOWS ACROSS MIDDLE TENNESSEE ARE NORMAL FOR THIS TIME OF
YEAR.

TEMPERATURE/PRECIPITATION OUTLOOK:

THE 8 TO 14 DAY OUTLOOK DOES INDICATE SLIGHTLY ABOVE NORMAL
PRECIPITATION AMOUNTS ALONG WITH BELOW NORMAL TEMPERATURES.

THE 3 MONTH OUTLOOK FOR DECEMBER...JANUARY AND FEBRUARY CALLS FOR A
SLIGHTLY HIGHER THAN AVERAGE CHANCE OF ABOVE NORMAL
TEMPERATURES...AND EQUAL CHANCES OF ABOVE...BELOW...OR NORMAL
PRECIPITATION.

GIVEN THE RECENT OCCURRENCE OF APPRECIABLE RAINFALL AMOUNTS ACROSS
THE AREA...AND MORE OF A WINTERTIME PATTERN EXPECTED...DROUGHT
CONDITIONS SHOULD CONTINUE TO BECOME LESS SEVERE IN THE WEEKS AHEAD.
