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 Jul 6, 3:05 PM CDT, 2 hours 8 minutes earlier.

Area forecast discussion, Jul 6, 3:05 PM CDT, 2 hours 8 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
305 PM CDT FRI JUL 6 2012

.SHORT TERM...SCATTERED THUNDERSTORMS HAVE ERUPTED OVER WESTERN
PARTS OF THE MID STATE THIS AFTERNOON IN RESPONSE TO A WEAK LOW
LEVEL CONVERGENCE BOUNDARY AND AN AREA OF SLIGHTLY ELEVATED
ATMOSPHERIC MOISTURE. WRF MODEL ALSO FORECASTS ANOTHER BAND OF
SLIGHTLY ELEVATED MOISTURE ALONG THE CUMBERLAND PLATEAU AND
WOULDN'T BE SURPRISED TO SEE SOME ISOLATED TO SCATTERED STORMS
DEVELOP THERE BY LATE AFTERNOON AS WELL. AS OF 230 PM...A FEW
ISOLATED STORMS HAD ALSO BEEN OBSERVED IN THE NASHVILLE METRO
AREA.

OUTSIDE OF THE THUNDERSTORMS, HOT TEMPERATURES AND HIGH HEAT
INDICES WERE ONCE AGAIN THE RULE. THE HIGH TEMPERATURE RECORD AT
NASHVILLE FOR THIS DATE, OF 100 DEGREES, SET WAY BACK IN 1874, HAS
BITTEN THE PROVERBIAL DUST...WITH THE MERCURY AT BNA ALREADY
SOARING AS HIGH AS 102 SO FAR TODAY. MEANWHILE...RESIDENTS OF THE
CUMBERLAND PLATEAU ALSO CONTINUE TO SWELTER IN THE HEAT...WITH THE
TEMPERATURE AT THE CROSSVILLE AIRPORT ALREADY REACHING THE DAILY
RECORD OF 93 DEGREES...AND THREATENING TO BREAK IT BEFORE DAY'S END.

ANOTHER SCORCHING DAY IS EXPECTED ON SATURDAY, AS TEMPS ARE
FORECAST TO ONCE AGAIN TOP 100 DEGREES WEST OF THE CUMBERLAND
PLATEAU AND HEAT INDICES SOAR BACK TO AROUND 105.

MODELS ARE CONSISTENT IN DEVELOPING A SIGNIFICANT WEATHER PATTERN
CHANGE STARTING ON SUNDAY AND CONTINUING FOR MUCH, IF NOT MOST, OF
THE UPCOMING WEEK. DEEP ATMOSPHERIC MOISTURE POOLS OVER THE LOWER
MISSISSIPPI VALLEY ON SATURDAY AND STARTS TO GET PULLED NORTHWARD
AND EASTWARD ACROSS THE TENNESSEE VALLEY ON SUNDAY, AHEAD OF AN
APPROACHING COLD FRONT.

LOOK FOR SCATTERED MAINLY AFTERNOON THUNDERSTORMS TO DEVELOP
SUNDAY, AND BECOME LIKELY SUNDAY NIGHT AND MONDAY, AS THE FRONT
PUSHES CLOSER TO OUR AREA. THE GFS HAS NOW PHASED IN CLOSER TO THE
OLDER ECMWF SOLUTION OF DRAGGING THE FRONT SOUTHWARD RATHER
SLOWLY. BY NOON MONDAY, THE FRONT SHOULD BE LOCATED NEAR THE KY-TN
LINE, THEN SAG SLOWLY SOUTHWARD AND REACH SOUTHERN PARTS OF THE
MID STATE BY 12Z TUESDAY.

.LONG TERM...CURRENT EXPECTATION IS FOR THE COLD FRONT TO BECOME
QUASI-STATIONARY TUESDAY OVER, OR NEAR, SOUTHERN PARTS OF THE MID
STATE AND LINGER IN THE SAME GENERAL AREA INTO LATE WEEK. SCATTERED
TO NUMEROUS THUNDERSTORMS WILL CONTINUE TO AFFECT PARTS OF OUR
AREA THROUGH THE PERIOD, MAINLY SOUTH AND EAST, WITH LESSER
CHANCES NORTHWEST.

EXPECT A REFRESHING BREAK FROM THE HEAT DURING THE EXTENDED
PERIOD, AS HIGHS TOP OUT MAINLY IN THE MID AND UPPER 80S, RATHER
THAN THE 100+ TEMPS WE'VE GROWN ACCUSTOMED TO.
