AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
322 AM CDT TUE JUL 1 2003

THROUGH WEDNESDAY...WX TO REMAIN QUIET AS HIGH PRESSURE DRIFTS EAST
OF THE REGION. FRONT ACROSS CENTRAL MISSOURI/SOUTHERN ILLINOIS TO
REMAIN THERE TODAY AND ALLOW DIURNAL TSRA DEVELOPMENT JUST SOUTH OF
THE CWFA. REMNANTS OF BILL TO MISS THE AREA WITH ONLY POTENTIAL
EFFECT BEING AN INCREASE IN LOW LEVEL MOISTURE...MAINLY EAST OF THE
MISSISSIPPI. BEYOND THAT...PERSISTENCE BEST TOOL WITH MAX TEMPS
WITH DIURNAL CU FIELDS DEVELOPING. FORECAST SOUNDINGS SHOW AN
INCREASE OF HIGH LEVEL MOISTURE BEGINNING TONIGHT THROUGH WEDNESDAY.

WEDNESDAY NIGHT AND THURSDAY...
UPPER LEVEL RIDGE GRADUALLY BREAKS DOWN THROUGH THIS TIME
FRAME...WITH THE SURFACE LOW DEVELOPING OVER THE CANADIAN HIGH
PLAINS.  THE SOUTHERLY FLOW THAT KICKS IN OVER THE AREA WEDNESDAY
NIGHT WILL GRADUALLY BRING IN MORE MOISTURE TO THE AREA...BUT
PROBABLY NOT ENOUGH TO CREATE SOME THUNDERSTORMS WITH THE UPPER
LEVEL VORT MAX THAT MOVES THROUGH THE AREA ON THURSDAY.  WILL KEEP
THURSDAY DRY FOR NOW...BUT LATER SHIFTS MAY NEED TO RE-EVALUATE.

FRIDAY THROUGH MONDAY...
THIS TIME FRAME TO BE RATHER ON THE DAMP SIDE...WITH THE FRONT
MOVING THROUGH THE AREA ON FRIDAY AND FRIDAY NIGHT...AND ASSOCIATED
PRECIPITATION CHANCES.  THE FRONT THEN LAYS OUT OVER NORTHERN
MISSOURI...AND WITH IT IN THE VICINITY CANNOT RULE OUT CHANCES FOR
PRECIPITATION FOR SATURDAY...WITH BEST CHANCES OVER THE SOUTHERN
PORTIONS OF THE CWA.  SUNDAY THE FRONT COMES BACK NORTH AGAIN AS A
WARM FRONT...AND ONCE AGAIN LOOKS PRETTY GOOD FOR PRECIP.  MONDAY TO
BE DRY AT THIS TIME...WITH 700MB TEMPS WARM ENOUGH TO BE CAPPED IN
THE WARM SECTOR.

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