Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm 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.

The nearest sounding before it

Nashville Metro, TN (KBNA), launched 12:00Z, 10.3 hours before the alert went out and 178 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
259 PM CST MON JAN 2 2006

.SHORT TERM...COLD FRONT IS MAKING ITS WAY THROUGH MIDDLE
TENNESSEE, ALTHOUGH THE WIND SHIFT BOUNDARY IS STILL FAR UPSTREAM
TO OUR WEST. CONVECTION THAT HAD FORMED ALONG THE FRONT HAS ALL
BUT DISSIPATED ON OUR SIDE OF THE STATE LINE AS DRIER AIR MANAGED
TO WORK ITS WAY IN AHEAD OF THE COLD FRONT. STILL, THE
TEMPERATURE AT NASHVILLE PEAKED AT 75 DEGREES EARLIER THIS
AFTERNOON, BREAKING THE RECORD HIGH FOR THIS DATE BY 5 DEGREES.

.LONG TERM...LOOK FOR THE UPPER LOW TO PASS JUST NORTH OF THE MID
STATE OVERNIGHT, MEANING WE WILL BE GETTING SOME OF THE OCCLUDED
FRONTAL MOISTURE ADVECTING INTO THE AREA, AND PROBABLY SOME LIGHT
RAIN.

SKIES WILL CLEAR OUT TOMORROW UNDERNEATH A STRONG NORTHWEST FLOW
ALOFT. QUICK RETURN FLOW ON WEDNESDAY WILL BRING A BRIEF SPELL OF
WARMER WEATHER BEFORE THE NEXT COLD FRONT BRINGS A RETURN TO
SEASONAL TEMPERATURES. A WEAK SHORTWAVE WILL BRING A CHANCE OF
RAIN AND/OR SNOW THURSDAY NIGHT AND FRIDAY, BUT THATS REALLY THE
ONLY LOOK WELL GET AT ANY PRECIPITATION AFTER TONIGHT.
