.DISCUSSION...
MID/UPPER LEVEL RIDGING STRETCHES FROM CENTRAL AL AND MS EASTWARD
INTO THE ATLANTIC. SW FLOW ALOFT IS APPARENT ACROSS WESTERN TN.

RADAR SHOWING A NEARLY SOLID BAND OF CONVECTION FROM BOLIVAR TN
NORTHWARD THROUGH THE DOVER AND PARIS AREAS. ELSEWHERE ACROSS THE
MID STATE...ONLY ISOLATED LIGHT SHOWER ACTIVITY EXISTS.

AFOREMENTIONED CONVECTION BAND IS OCCURRING NEAR THE SPINE OF A N-S
SFC TROUGH. THIS FEATURE IS EXPECTED TO LIFT SLOWLY NORTHWARD
OVERNIGHT AND BECOME ALIGNED NW-SE. THUS...AFTER 06Z...BETTER
ORGANIZED CONVECTION WILL LIKELY BE NORTH OF THE MID STATE.

FOR THE UPDATE...IN ADDITION TO GETTING RIF OF THE LATE AFTERNOON
WORDING...WILL TREND POPS DOWNWARD. HIGHER EVENING POPS WILL STILL
RESIDE ACROSS WESTERN ZONES AS PER THE CURRENT ACTIVITY AND THE
POSITION OF THE SFC TROUGH.

OTW...WITH MOST OF MIDDLE TN ON THE EAST SIDE OR SOUTH OF THE
TROUGH...SHOULD SEE LIGHT SOUTH WINDS CONTINUE. CURRENT DEW POINTS
ARE GENERALLY IN THE 70 TO 75 DEGREE RANGE. SO...UPPER 60S MINIMUM
TEMPS FOR MOST AREAS LOOKS REASONABLE.

TIME HEIGHT DIAGRAMS STILL SHOW PLENTIFUL MOISTURE IN PLACE SO WILL
CONTINUE WITH A MOSTLY CLOUDY SKY. FINAL ADJUSTMENT WILL BE TO
INCLUDE PATCHY FOG LATE. NUMERICAL SOLUTIONS IN LINE WITH VSBYS
APPROACHING A MILE OR LESS AT BNA AND CSV AS WE MOVE TOWARD SUNRISE.

Heavy Rain, Warren

When: September 25, 12:00 AM CST to 1:00 AM CST
Where: Warren County, 1.85 mi SW of Shady Rest
Property damage: $10,000
Reported by: Newspaper
Coordinates: 35.699, -85.741

The historic Birthing Tree, which has been estimated to be between 200 and 400 years old, lost one huge limb which fell onto Sparta Street, blocking the street, and causing downed telephone lines. The city landscape manager reported that the added weight from the heavy rainfall that morning resulted in the limb breakage, as the tree had recently been inspected by an arborist and this particular limb was deemed healthy.

What these are

Heavy Rain: Rainfall totals unusual for the place and season that did not produce a flood.

After NWS Directive 10-1605, the rules offices file Storm Data by.
