AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM, AL
239 PM CDT MON JUL 22 2002

UPPER LOW ACROSS PORTIONS OF GEORGIA WILL SLOWLY MOVE TO THE WEST
TONIGHT THROUGH TUESDAY AND GRADUALLY WEAKEN.  FRONT ACROSS THE
GREAT LAKES IS FORECAST TO DROP SOUTHEAST AND APPROACH THE AREA
TUESDAY INTO TUESDAY NIGHT.  AT THIS POINT BELIEVE THAT THE FRONT
WILL FALL APART BEFORE REACHING THE AREA.  HOWEVER...MODELS SHOW AN
IMPULSE DROPPING FROM THE GREAT LAKES SOUTHWARD INTO THE AREA LATE
TUESDAY NIGHT THROUGH WEDNESDAY...THEN LINGERING ACROSS THE WESTERN
SECTIONS OF THE AREA ON THURSDAY.

FOR TONIGHT...BELIEVE THAT MUCH OF THE TSTM ACTIVITY WILL GO AWAY AS
WE LOOSE THE HEATING OF THE DAY.  POPS WILL BE BASED ON LATEST RADAR
JUST BEFORE RELEASE TIME.  SCATTERED POPS FOR THE ENTIRE AREA ON
TUESDAY...THEN CONTINUED SCATTERED POPS NORTH TUESDAY NIGHT WITH
LOWER POPS TOWARDS THE SOUTH.  WITH IMPULSE/VORT MAX MOVING INTO
THE AREA WEDNESDAY AND LINGERING THURSDAY...WILL CONTINUE WITH
SCATTERED POPS EACH DAY.

LOOKING TOWARDS THE WEEKEND...BELIEVE THAT SLIGHTLY DRIER AIR
WILL BEGIN TO SPREAD INTO THE AREA ON FRIDAY AND CONTINUE THROUGH
THE WEEKEND.  LOOKS LIKE WE CAN BROADBRUSH THE FORECAST WITH
PARTLY CLOUDY SKIES AND A CHANCE OF AFTERNOON AND EVENING
SHOWERS/TSTMS EACH DAY.
