AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
950 AM EDT SUN AUG 31 2014

.DISCUSSION...CHALLENGE FOR FORECAST THIS MORNING IS HOW FAR EAST
THE STEADY STREAM OF SHOWERS AND TSRA SPREAD...AS THE SHORTWAVE
TROUGH TO OUR NORTH TRACKS ACROSS THE GREAT LAKES AND OHIO VALLEY.
THE SHORT RANGE MODELS...MAINLY THE HRRR AND RAP...SEEM MORE
REASONABLE IN KEEPING THE BEST COVERAGE ACROSS OUR WRN COUNIES.
FORECAST GRIDS GENERALLY IN LINE WITH THIS SCENARIO...BUT WILL
MONITOR RADAR DEVELOPMENTS FOR THE REST OF THE MORNING.

EXTENSIVE CLOUD COVER COULD HINDER MAX TEMPS THIS AFTERNOON...ALTHO
MIN TEMPS WERE VERY MILD...SO REACHING 80S TO NEAR 90 DEGREES IS
QUITE POSSIBLE.

FORECAST GRIDS AND PRODUCTS LOOK GOOD WITH NO UPDATES NEEDED UNLESS
THE SHOWERS WORK FURTHER EAST OF I-75 AND I-81...WHERE SCATTERED
WORDING AND HIGH CHANCE POPS ARE FORECAST.
