THIS HAZARDOUS WEATHER OUTLOOK IS FOR MIDDLE TENNESSEE.

.DAY ONE...THIS AFTERNOON AND TONIGHT

A STRONG LOW PRESSURE SYSTEM OVER WESTERN LOUISIANA AT NOON WILL
CONTINUE TO MOVE NORTHEAST TOWARD MIDDLE TENNESSEE DURING THE AFTERNOON
AND EVENING WITH RAIN SPREADING OUT AHEAD OF THE SYSTEM THAT WILL
MOVE INTO SOUTHWEST MIDDLE TENNESSEE DURING THE AFTERNOON AND INTO
THE NASHVILLE AREA AROUND 6 PM. RAINFALL WILL INCREASE THIS
EVENING AS THE LOW CENTER GETS CLOSER TO MIDDLE TENNESSEE. LOCALLY
HEAVY RAINFALL IS POSSIBLE WITH THIS SYSTEM TONIGHT. WE ARE
EXPECTING A TOTAL OF ONE TO TWO INCHES OF RAINFALL FROM THIS STORM
SYSTEM WITH THE HIGHER AMOUNTS OVER THE SOUTHEAST HALF OF THE MID
STATE.

THE SYSTEM MAY ALSO GENERATE ISOLATED SEVERE THUNDERSTORMS OVER
THE AREA...SOUTH OF INTERSTATE 40 TONIGHT. THE GREATEST THREAT
FROM SEVERE STORMS WILL BE DAMAGING WINDS AND ISOLATED TORNADOES.

GIVEN THE INTENSITY OF THE LOW PRESSURE SYSTEM THE STORM WILL
ALSO GENERATE STRONG WINDS OVER THE AREA TONIGHT. EXPECT SUSTAINED
WINDS OF 15 TO 25 MPH WITH GUSTS AS HIGH AS 35 MPH.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY...

MUCH COLDER AIR WILL POUR INTO THE REGION IN THE EARLY MORNING
HOURS ON WEDNESDAY IN THE NORTHWEST AND SPREAD EAST DURING THE
DAY WEDNESDAY. THIS WILL SLOWLY CHANGE THE PRECIPITATION FROM RAIN
TO SNOW. FORTUNATELY THE LOW WILL TRACK RIGHT ACROSS THE AREA AND
PULL OUT OF THE AREA IN THE AFTERNOON ON WEDNESDAY. THIS SHOULD
LIMIT THE AMOUNT OF SNOWFALL TO AROUND ONE INCH OR LESS.

.SPOTTER CALL TO ACTION STATEMENT...

SEVERE WEATHER REPORTS FROM TRAINED WEATHER SPOTTERS MAY BE
NEEDED.

TO REPORT ANY SNOW ACCUMULATIONS TO THE NATIONAL WEATHER SERVICE
