What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Nashville, TN wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 4, 3:25 AM CDT, 10 hours 46 minutes earlier.

Area forecast discussion, Aug 4, 3:25 AM CDT, 10 hours 46 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
325 AM CDT THU AUG 4 2005

.DISCUSSION...WEATHERWISE, TONIGHT WAS JUST ANOTHER LINK IN THE
CHAIN OF SUMMER DOLDRUMS. IT WAS ANOTHER NIGHT OF MOSTLY CLEAR
SKIES AND TEMPERATURES IN THE MID 60S TO LOWER 70S.

MORE HOT WEATHER IS IN STORE FOR US TODAY, WITH THE HEAT INDEX AT
BNA EXPECTED TO REACH 99 DEGREES.

STILL LOOKS LIKE A FRONT WILL MOVE ACROSS THE AREA FRIDAY AND PRODUCE
A CHANCE FOR THUNDERSTORMS. THE SHALLOW FRONT WILL LIKELY WASH OUT
BY SUNDAY, WITH WINDS SWITCHING FROM THE NORTHEAST TO A MORE TYPICAL
SOUTHERLY SUMMERTIME DIRECTION.

THE GFSMEX EXTENDED FORECAST STILL LOOKS A LITTLE SUSPECT WITH ITS
MOISTURE AND PRECIP SOLUTION DURING THE FIRST HALF OF NEXT WEEK.
GFS HAS ALREADY SHOWN SOME INCONSISTENCY IN ITS HANDLING OF WEAK
GULF COAST LOW PRESSURE SYSTEM AND, BASED ON MINIMAL MODEL CONFIDENCE
FOR THAT PERIOD, AM HESITANT TO PUSH POPS ABOVE CLIMO FOR THAT
PERIOD (AS SUGGESTED BY MEX DATA).

LOOKS LIKE JUST ANOTHER DAY OF THE STATUS QUO.
