AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
255 PM CDT SAT AUG 9 2003

SURFACE RIDGE ENTRENCHED OVER THE UPPER MISSISSIPPI VALLEY...WITH
UPPER RIDGE ACROSS THE WESTERN US AND TROUGH OVER THE EASTERN US.
MAIN CONCERN FOR THE SHORT TERM IS FOG POTENTIAL TONIGHT.  WITH RIDGE
OVERHEAD AND DEW POINTS IN THE UPPER 50S TO AROUND 60 TONIGHT...
EXPECT A REPEAT OF LAST NIGHTS PATCHY FOG DEVELOPMENT.

BEYOND TONIGHT...NEXT SIGNIFICANT WAVE TO DROP INTO THE BASE OF THE
TROUGH IS NOW ROUNDING THE TOP OF THE RIDGE IN NORTH DAKOTA.  THIS
WAVE WILL BRING OUR NEXT PRECIP CHANCE VIA MCS PROPAGATION SUNDAY
NIGHT INTO MONDAY...ALTHOUGH CHANCES APPEAR TO BE SLIM.

NEXT SURFACE RIDGE PUSHES IN LATE TUESDAY AND DRIES THINGS OUT FOR
THE MIDDLE AND END OF NEXT WEEK.  UPPER PATTERN FINALLY BEGINS TO
SHIFT LATE WEEK.  PRECIP CHANCES NEXT WEEKEND WILL DEPEND ON UPPER
RIDGE WEAKENING.  WILL KEEP LOW PRECIP CHANCES FRIDAY NIGHT INTO
SATURDAY...BUT WILL HAVE TO MONITOR UPPER PATTERN TRENDS CLOSELY.

.DVN...
IA...NONE.
IL...NONE.
MO...NONE.
