Area forecast discussion, Nov 30, 8:38 AM CST, 3 hours 45 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NASHVILLE TN 835 AM CST SUN NOV 30 1997 SVR STORM WORKING NORTH UP TOWARD KENTUCKY LAKE AND IT APPEARS WILL STAY OUT OF MY CWA AT THIS TIME. MAY HAVE TO DEAL WITH COLD POOL AS IT MOVES OVER THE AREA TODAY INCREASING INSTABILITY AND EVEN MORE SO IF SUN POPS OUT FOR A SHORT WHILE. LOOKS TO ME LIKE MID STATE MAY ALSO BE IN LEFT FRONT QUADRANT OF UPPER LEVEL JET MAX AT THIS TIME. WILL STAY CLOSE TO DOPPLER AND MAY HAVE TO SLING A FEW WARNINGS DURING THE DAY. WILL NOT ISSUE SEVERE WEATHER OUTLOOK AT THIS TIME SINCE SPC SEEMS TO BE SLEEPING ON THIS ONE AS 94O HAS NO SVR TSTMS FCST. PERHAPS THEY ARE THINKING ONLY AN ISOLATED EVENT. HOPE SO. BOYD 01
