AFTERNOON FORECAST DISCUSSION
300 PM EDT SUN JUL 13 2003

TONIGHT AND TOMORROW...PERSISTENT UPPER TROUGH OVER THE EASTERN
CONUS REMAINS MOST SIGNIFICANT FEATURE FOR OUR REGION. UPPER RIDGE
REMAINS ANCHORED OVER THE ROCKY MOUNTAIN REGION. TROUGH AXIS IS
PROJECTED TO REMAIN WEST OF THE FORECAST AREA THROUGH MID-DAY MONDAY
AT WHICH TIME THE WESTERN RIDGE BUILDS EASTWARD. EXPECT PRECIP
CHANCES TO DIMINISH AS TROUGH AXIS AND SURFACE BOUNDARY PUSH OUT OF
OUR AREA.

LONGER TERM...WITH UPPER TROUGH PULLING OUT...SHOULD BE ENOUGH
WARMING ALOFT TO DIMINISH THE AMOUNT OF SHOWER AND THUNDERSTORM
ACTIVITY FOR TUESDAY AND BEYOND. HOWEVER...STILL MAY BE ENOUGH ENOUGH
MOISTURE AND INSTABILITY FOR SLIGHT CHANCE TO LOW CHANCE POPS FOR
AFTERNOON AND EVENING CONVECTION.  TIMING OF ANY WEAK FEATURES THAT
WILL AFFECT THE REGION NEXT SEVERAL DAYS IS DIFFICULT.  FOR NOW WILL
GO WITH 20 TO 30 POPS EACH AFTERNOON AND EVENING THROUGH NEXT
SUNDAY.
