Area forecast discussion, Apr 28, 2:00 PM CDT, 2 hours 29 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
200 PM CDT SUN APR 28 2002

CONVECTION CURRENTLY FIRING IN A WIDELY SCATTERED FASHION ACROSS
NORTHERN AREAS...PARTICULARLY ACROSS THE NORTHERN PLATEAU WHERE
STRONG STORMS EXIST. SATELLITE IMAGERY AND SURFACE PLOTS SHOWING
THAT THE FRONT HAS RECENTLY ENTERED THE NORTHWESTERN PORTIONS OF
MIDDLE TN. LOOKS AS THOUGH THE DEGREE OF CONVERGENCE ALONG THE
ACTUAL FRONT APPEARS HAMPERED AS THE DIRECTIONAL CONVERGENCE IS
BEING COMPROMISED BY DIVERGING SPEEDS ALONG THE BOUNDARY.

WILL NEED TO HINGE 1ST PERIOD ON THE TIMING OF THE FROPA. WILL ALSO
USE LATEST RADAR TRENDS PRIOR TO POST TIME AND USE A THIS EVENING
PERIOD IF NEEDED.

OTHERWISE...IT APPEARS THAT THE FROPA IS SCHEDULED THROUGH THE BNA
AREA AROUND 22Z AND THE PLATEAU BY 02Z. ONCE THE FRONT
PASSES...SKIES SHOULD BECOME PARTLY CLOUDY THROUGH TONIGHT. LARGE
LOW LEVEL CLOUD COVER BEHIND THE FRONT IS PULLING TO THE NORTHEAST
SO THAT SHOULD NOT EFFECT THE AREA. NORTHWEST WINDS WILL ALLOW TEMPS
TO COOL DOWN TO NEAR 50 TONIGHT...JUST A HAIR UNDER THE MOS GUIDANCE.

MONDAY AND MONDAY NIGHT IT LOOKS COOLER AND DRIER WITH A RETURN OF
SUNSHINE. THE NEXT WEATHER MAKER WILL BE FOR TUESDAY AFTERNOON
THROUGH WEDNESDAY AS A FRONTAL BOUNDARY MOVES SOUTH TOWARD TN. BEST
LIFT WITH THIS FEATURE APPEARS TO BE OVER KY AS THE BOUNDARY NEVER
DOES QUITE MAKE IT DOWN TO THE MID STATE. WILL GO AHEAD AND KEEP
POPS IN THE 40-50 RANGE AS THE SOUTHERN EXTENT OF THE BOUNDARY IS AN
UNCERTAINTY AT THIS TIME.

A COLD FRONT WILL CLEAR THINGS OUT AGAIN ON THURSDAY WITH SLIGHTLY
COOLER TEMPS BEHIND IT.
