AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 417 PM CDT SUN JUL 11 2004 .SYNOPSIS... LARGE MCS COMPLEX MOVED ACROSS THE CWA TODAY...WITH SOME ISOLATED SEVERE REPORTS. ALL THIS ASSOCIATED WITH AN UPPER LEVEL VORT MAX TRANSITIONING ACROSS THE AREA...MOVING INTO SOME EXTREMELY JUICY... UNSTABLE AIR. THE EXTRA MOISTURE KEPT THE STORMS FROM GETTING TOO OUT OF HAND...WITH NO HAIL REPORTS...MAINLY LOTS OF VERY HEAVY RAIN AND A FEW WIND REPORTS. && .SHORT TERM...(TONIGHT AND MONDAY) BUSY WEATHER TODAY OUGHT TO GRADUALLY DIMINISH INTO THE EVENING HOURS...WITH THE MAIN VORT MAX FINALLY SHIFTING EAST OF THE AREA. THERE IS ANOTHER VORT MAX OVER EASTERN NEBRASKA...BUT THE CONVECTION ASSOCIATED WITH THIS WAVE SHOULD BEGIN PROPAGATING MORE SOUTHEAST...AS IMPLIED BY THE PRESSURE FALLS AHEAD OF IT AND THE HIGHER INSTABILITY LEVELS TO ITS EAST SOUTHEAST. HAVE KEPT CHANCES OF SHOWERS AND THUNDERSTORMS IN THROUGH MIDNIGHT...MAINLY SOUTH.... WHERE THIS WAVE MAY BE ABLE TO AFFECT THE AREA BEFORE IT GETS TOO FAR SOUTH. THE AIRMASS OVER THE CWA PROBABLY WILL NOT SUPPORT SIGNIFICANT CONVECTION AGAIN TONIGHT...ITS BEEN WELL WORKED OVER ...SO HAVE ALSO CANCELED WATCH THAT WAS TO BE IN EFFECT UNTIL 6 PM. DEWPOINTS DONT SCOUR OUT TONIGHT...AND WITH ALL THE RAIN...HAVE ADDED IN AREAS OF FOG FOR ALL OF THE CWA FOR AFTER MIDNIGHT. IT MAY GO DENSE AGAIN...BUT WILL LET LATER SHIFTS DECIDE ON ANY ADVISORYS AS THE CONDITIONS DEVELOP. MONDAY TO BE QUIET AGAIN. KEPT DEWPOINTS RELATIVELY HIGH...IT DOES NOT APPEAR THAT THEY WILL SCOUR OUT...SO IT WILL BE MUGGY AND HOT...ESPECIALLY ACROSS THE SOUTH. && .LONG TERM...(MONDAY NIGHT THROUGH SUNDAY)... MONDAY NIGHT THROUGH TUESDAY NIGHT...MONDAY NIGHT TO HAVE ONE MORE MCS FIRE UPSTREAM OF THE CWA...IN THE SW CORNER OF MN..FAR NE NEBRASKA...SE SOUTH DAKOTA...AND NW IOWA AREA. THIS MCS SHOULD ROLL TOWARDS THE AREA OVERNIGHT...AND MAY APPROACH THE CWA BY EARLY MORNING. SOME TIMING ISSUES STILL WITH THIS FEATURE. EITHER WAY... IT SHOULD ALSO AFFECT TUESDAY. BEST CHANCES LOOK TO BE ACROSS THE NORTHERN PORTIONS OF THE CWA. BY TUESDAY NIGHT WE DRY OUT AGAIN... WITH NORTHWEST FLOW. COULD BE A COOL NIGHT...BUT WITH THE CORN GOING ON PAST 6 FT ATTM...HIGH DEWPOINTS WILL HOLD MIN TEMPS IN THE 60S. WEDNESDAY THROUGH SUNDAY...THINGS STILL LOOK RATHER QUIET IN THE WEDNESDAY THROUGH EARLY SATURDAY TIME FRAME...WITH STRONG NORTHWEST FLOW ALOFT OVER THE AREA AND A SURFACE RIDGE GRADUALLY TRANSLATING SOUTHEAST ACROSS THE AREA. HAVE GONE WITH SLIGHTLY COOLER THAN NORMAL TEMPERATURES ACROSS THE BOARD WITH THE NORTHWEST FLOW... THOUGH THURSDAY COULD BE QUITE SUNNY. SATURDAY AND SUNDAY THINGS BEGIN TO LOOK INTERESTING AGAIN...WITH SOME SORT OF WAVE TOPPING THE UPPER LEVEL RIDGE TO THE WEST...AND A SURFACE LOW DEVELOPING OVER THE HIGH PLAINS. A WEAK WARM FRONT DEVELOPS SOMEWHERE ACROSS THE UPPER MIDWEST...AND EXPECT THAT ANYWHERE NEAR IT WILL HAVE A CHANCE OF SHOWERS AND STORMS. MODELS HAVE BEEN A BIT CHANGEABLE AND HAVE LITTLE AGREEMENT BETWEEN DIFFERENT MODELS FOR THIS TIME RANGE...SO HAVE NOT CHANGED VERY MUCH FOR THESE PERIODS FROM PREVIOUS FORECAST. && .DVN WATCHES/WARNINGS/ADVISORIES...
