AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
745 PM CDT FRI APR 19 1996

SELS HAS SVR WX THREAT PRETTY WELL NAILED DOWN FOR TIME BEING.
FOLLOWED MEM LEAD AND ISSUED SPS FOR MID STATE AT 5 PM AND WILL
UPDATE SHORTLY ON THE POTENTIAL FOR SVR WX AFTER GIVING MEM A CALL.

BNA 00Z SOUNDING SHOWING SUBSIDENCE INVERSION WITH STRONG CAP
/4.2 DEGREES CELSIUS/ AROUND 850 MBS WITH DECENT LOW LEVEL MOISTURE
BUT AIR MASS HAS DRIED OUT SINCE EARLIER IN THE DAY AS NEXT SHORT
WAVE WASTE LITTLE TIME PUSHING EAST FROM PLAINS TONIGHT AND THIS TIME
IT MEANS BUSINESS.

MY IMPRESSION FROM GRIDDED DATA IS THAT BULK OF ENERGY AND LESS HOPE
BULK OF THE SVR WX WILL STAY WEST AND NORTH OF MID STATE.  NOT TO
SAY THE CHANCE DOESNT EXIST BECAUSE IT CERTAINLY DOES ESPECIALLY AFTER
MIDNIGHT FOR MIDDLE TN.

SELS 94O MATCHES MY THINKING FROM EARLIER MODEL RUNS.
BNA 00Z HODOGRAPH IS IMPRESSIVE ESPECIALLY FOR ANY RIGHT MOVERS.

CAPPING INVERSIONS CAN STORE UP ALOT OF ENERGY THAT GETS RELEASED
BY ONLY A FEW SUPERCELLS...OFTEN TIMES THE FIRST ONES TO BREAK THE CAP
ARE THE WORST.

TEMPS MAY BE A CATEGORY TOO LOW FOR FIRST PERIOD...OTHERWISE LIKE
THE WAY FORECAST IS WORDED FOR MID STATE.

PLANN ON GIVING MEM A CALL AROUND 8 PM CDT.
