Area forecast discussion, May 2, 2:31 PM CDT, 2 hours 2 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
231 PM CDT THU MAY 2 2002

CURRENTLY, FRONT CONTINUES TO EDGE ACROSS THE MID STATE, WITH A
STRONG TEMPERATURE CONTRAST ALONG THE FRONT. IT APPEARS THE SEVERE
THUNDERSTORM WATCH IS NOT GOING TO MATERIALIZE, AS THE LOW-LEVEL
ENVIRONMENT IS JUST NOT UNSTABLE ENOUGH TO SUPPORT WIDESPREAD
CONVECTION. UNLESS SOMETHING BEGINS TO POP DURING THE NEXT HOUR,
PLAN TO CANCEL THE WATCH BEFORE ISSUING THE AFTERNOON ZONE FORECAST
PACKAGE.

MODELS SHOW FRONT STALLING OUT OVER THE TENNESSEE VALLEY TOMORROW,
THEN RETURNING AS A WARM FRONT AS PART OF ANOTHER DEVELOPING LOW
CENTER. MORE CONVECTION IS EXPECTED FRIDAY NIGHT AND INTO SATURDAY
BEFORE THIS SYSTEM FINALLY PULLS EAST. DONT EXPECT MUCH TEMPERATURE
CHANGE, AS THIS NEXT SYSTEM WILL BE MORE MESOSCALE, AND THEREFORE
WONT PULL IN MUCH OF AN AIR MASS CHANGE. LOOKING AHEAD,
TEMPERATURES NEXT WEEK WILL LIKELY REMAIN AROUND NORMAL, WITH
ANOTHER FRONTAL SYSTEM BRINGING A CHANCE OF RAIN TO THE MID STATE
SUNDAY NIGHT AND INTO TUESDAY.

.BNA...SEVERE THUNDERSTORM WATCH ALL MIDDLE TENNESSEE COUNTIES UNTIL
00Z.
