Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
938 PM EST THU FEB 5 2004

.DISCUSSION...
EASTERN EDGE OF RAIN AREA HAS MADE LITTLE PUSH EASTWARD THIS EVENING
AS EAST TO SOUTHEAST STRONG LOW LEVEL FLOW CONTINUES TO PRODUCE
DOWNSLOPING INTO MUCH OF THE CENTRAL AND NRN PARTS OF THE TENNESSEE
VALLEY.  THUS FAR...ONLY THE WESTERN MOST PARTS OF THE FORECAST AREA
GAVE RECEIVED SIGNIFICANT RAINS...PRIMARILY OUR SEQUATCHIE VALLEY
AND NE CUMBERLAND PLATEAU COUNTIES.  HOWEVER...AS THE SURFACE LOW
TRACKS NORTHEAST OVERNIGHT AND PUSHES THE COLD FRONT EASTWARD...EVEN
THE DRY AREAS OF NE TN AND SWRN VA WILL EVENTUALLY GET AT LEAST
MODERATE RAINS LATE TONIGHT INTO FRIDAY MORNING.  ETA MODEL CUTS THE
RAINFALL OFF RATHER ABRUPTLY BY 18Z FRIDAY FOR ALL BUT EXTREME NE
PARTS OF OUR FORECAST AREA.  THIS IS STILL A BIT FASTER THAN THE
INCOMING 06/00Z NGM MODEL.

ANYWAY...THE FLOOD WATCH LOOKS GOOD TO RUN THROUGH 4PM EST FRIDAY
...WHICH SHOULD COVER THE END OF THE RAIN AS WELL AS ANY RUNOFF.
LITTLE GROUND TRUTH REPORTS FROM HIGHER ELEVATIONS CONCERNING WIND
SPEEDS THIS EVENING...BUT KMRX VAD WIND PROFILE (VWP) DOES SHOW 35
TO 40 KNOT WIND SPEEDS BELOW 5000 FOOT LEVEL.  WILL CONTINUE WITH
THE WIND AND LAKE WIND ADVISORIES THROUGH 4AM EST AND LET MIDNIGHT
SHIFT EXTEND IF NEEDED.  UPDATED FLOOD WATCH (FLSMRX) AND WIND
ADVISORIES (NPWMRX) WILL FOLLOW SHORTLY.

OTHERWISE...ZONES AND WEB PRODUCTS GENERALLY ON TRACK...BUT MAY NEED
TO MAKE SLIGHT ADJUSTMENTS TO MIN TEMP FORECAST IN A FEW GROUPS.
