AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
345 PM EDT THU JUN 30 2005

.SHORT TERM (TONIGHT THROUGH FRIDAY)...WEAK SHORTWAVE AND
INSTABILITY TRIGGERING ISOLATED THUNDERSTORMS OVER THE AREA...MAINLY
ALONG THE HIGHER ELEVATIONS.  SCATTERED CONVECTION SHOULD CONTINUE
INTO THE EVENING HOURS...THEN DIMINISH WITH THE LOSS OF SURFACE
HEATING.  WILL KEEP SLIGHT CHANCE POPS INTO THE OVERNIGHT HOURS WITH
COLD FRONT ENTERING REGION.  FRONT SHOULD PASS THROUGH FRIDAY.
PRETTY GOOD INSTABILITY AND UPPER DIVERGENCE ALONG WITH FRONT...WILL
KEEP HIGH CHANCE POPS FOR FRIDAY.  WITH THE FRONT PASSING THROUGH...
STRONG TO SEVERE STORMS WILL BE POSSIBLE ON FRIDAY AFTERNOON.

.LONG TERM (FRIDAY NIGHT THROUGH THURSDAY)...STRONGER REENFORCING
COOLER AIR ENTERING CWA FROM NORTHWEST WILL BE RUNNING INTO UNSTABLE
AIR MASS FRIDAY EVENING...BUT WILL BE STARTING TO STABLIZE AFTER
SUNSET.  ANOTHER PROBLEM WILL BE THE AMOUNT OF INSTABILITY LEFT IN
AREA FROM AFTERNOON CONVECTION AND POSSIBLE WAVE OF PRECIP FROM
EARLIER IN THE DAY.  WILL DIMINISH POPS OVERNIGHT...WITH BEST
CHANCES IN THE NORTHEAST AND MOUNTAINS.

SATURDAY THROUGH ABOUT NOON MONDAY...COOLER/STABLE AIR MASS SAGS
INTO REGION...WILL ONLY HAVE SLGT POPS IN APP MOUNTAINS SUNDAY
AFTN.

BY MONDAY AFTERNOON...WILL START UP SUMMER SHOWER/TSTM REGIME
AGAIN.  LOOKS LIKE UPPER LEVEL RIDGING EARLY IN THE WEEK WILL GIVE
WAY TO TROUGH LATE IN THE WEEK.  WILL SLOWLY RAISE POPS DURING WEEK
IN ANTICIPATION OF UPPER TROUGH.

GENERALLY GOING ON COOL SIDE OF GUIDANCE...THINK OVER THE WEEKEND
COOLER AIR MASS WILL FILL IN BETTER THAN MODELS SHOWING...THINK THEY
ARE HAVING TROUBLE RESOLVING TERRAIN EFFECTS ON AIR MASS...THINK
WHOLE WEST SIDE OF APPS WILL GET FULL COOL AIR MASS OVER
WEEKEND...MODELS HINT THAT AIR MASS WONT MODIFY THAT MUCH...BUT
THINK IT WILL.  ALSO...MODEL HIGH TEMPS LOOK A LITTLE TOO WARM FOR
SCENARIO NEXT WEEK.
