THIS HAZARDOUS WEATHER OUTLOOK IS FOR MIDDLE TENNESSEE.

.DAY ONE...TONIGHT...
CONVECTION OVERNIGHT IN MIDDLE TENNESSEE IS EXPECTED TO REMAIN
BELOW SEVERE LIMITS...HOWEVER SMALL HAIL IS POSSIBLE IN ISOLATED
STORMS.

SHOWERS AND ISOLATED THUNDERSTORMS WILL INCREASE IN COVERAGE IN
THE OVERNIGHT HOURS. THE SHOWERS AND ISOLATED THUNDERSTORMS ARE
DEVELOPING ON THE NOSE OF A LOW LEVEL JET...IN AN AREA OF STRONG
LOW LEVEL WARMING AND SURFACE MOISTURE CONVERGENCE.

IN ADDITION...A WARM FRONT WILL PULL NORTHWARD INTO MIDDLE TENNESSEE
OVERNIGHT. THE WARM FRONT WILL ENHANCE THE SHOWERS AND THUNDERSTORMS
ACROSS THE NORTH HALF OF MIDDLE TENNESSEE.

THE LACK OF THERMODYNAMIC INSTABILITY APPEARS TO BE THE LIMITING
FACTOR FOR SEVERE WEATHER IN MIDDLE TENNESSEE TONIGHT.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...
A DEEP LOW PRESSURE CENTER WILL MOVE ACROSS THE OHIO VALLEY FRIDAY
NIGHT, DRAGGING A STRONG COLD FRONT ACROSS THE MID STATE DURING THE
LATE EVENING AND EARLY MORNING. IT APPEARS THAT SEVERAL ATMOSPHERIC
INGREDIENTS WILL COME TOGETHER TO CREATE THE POTENTIAL FOR SEVERE
STORM DEVELOPMENT ALONG OR JUST AHEAD OF THE SURFACE FRONT. IN
ADDITION TO LOW LEVEL SATURATION AND DEEP INSTABILITY, DRY AIR IN THE
MID LEVELS WILL INCREASE THE SEVERE STORM POTENTIAL, AND STRONG WIND
SHEAR JUST ABOVE THE SURFACE WILL ENHANCE SUPERCELL DEVELOPMENT.

AS A RESULT, THE STORM PREDICTION CENTER HAS PLACED ALL OF MIDDLE
TENNESSEE UNDER A SLIGHT RISK OF SEVERE WEATHER, WITH A MODERATE
RISK OVER WEST TENNESSEE AND THE WESTERN FRINGES OF MIDDLE
TENNESSEE FOR FRIDAY AND FRIDAY NIGHT.

.SPOTTER INFORMATION STATEMENT...
SPOTTERS AND EMERGENCY MANAGERS MAY BE NEEDED FRIDAY NIGHT. PLEASE
STAY TUNED TO SUBSEQUENT FORECASTS AND HAZARDOUS WEATHER OUTLOOKS.
