NWS St. Louis, MO wrote its last area forecast discussion before the first event at Jul 29, 3:27 AM CST, 1 hour 3 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ST LOUIS MO 427 AM CDT TUE JUL 29 2008 .DISCUSSION... /426 AM CDT TUE JUL 29 2008/ PRIMARY CONCERN FOCUSES ON HEAVY RAIN POTENTIAL OVER THE NEXT 24-48 HOURS AS REMNANT MOISTURE AND DYNAMICAL LIFT FROM HURRICANE DOLLY TRACKS EAST FROM THE PLAINS INTO THE MID-MISSISSIPPI VALLEY. REMNANT VORTEX IS WEAK AND DIFFUSE AT ALL LEVELS...AND IS THEREFORE DIFFICULT TO TRACK AND FORECAST MOVEMENT. HOWEVER...THERE IS LITTLE DOUBT THAT DEEP TROPICAL MOISTURE IS INCREASING OVER THE PLAINS AS EVIDENCED BY THE HUGE RAIN SHIELD THAT COVERS MOST OF KANSAS AN OKLAHOMA THIS MORNING...AS WELL AS INCREASING P-WATS OVER THAT SAME AREA ON THE 00Z UPPER AIR RUN. BOTH THE GFS AND THE NAM STEADILY INCREASE P-WATS TO BETWEEN 2-2.5 INCHES ACROSS NORTHERN/WESTERN MISSOURI BY 12Z WEDNESDAY MORNING. WITH THE ILL-DEFINED REMNANT VORTEX OF DOLLY DRIFTING INTO THE LOWER MISSOURI/MID-MISSISSIPPI VALLEY AND A 20-30KT LOW LEVEL JET AIMED INTO WESTERN/CENTRAL MISSOURI BETWEEN 06Z-12Z TONIGHT...IT LOOKS LIKE IT WILL BE RATHER WET. HPC GUIDANCE FORECASTS THE HEAVIEST RAINS TO FALL OVER NORTHWEST/NORTH CENTRAL MISSOURI TONIGHT WITH A LITTLE FINGER EXTENDING INTO NORTHEAST MISSOURI BY 12Z. CANT FIND ANY REASON TO DISAGREE WITH THAT FORECAST SO HAVE STUCK PRETTY CLOSE TO 06Z HPC GUIDANCE FOR QPF WHICH GIVES THE AREA BETWEEN 1 AND 2 INCHES THROUGH THURSDAY NIGHT AS THE TROPICAL RAINS CONTINUE. THIS SEEMS LIKE A GOOD FIRST SHOT...AND WOULD NOT BE SURPRISED TO SEE LOCALLY HIGHER AMOUNTS. GFS AND NAM ARE IN PRETTY GOOD AGREEMENT OUT TOWARD THE END OF THE WEEK IN BUILDING A STRONG UPPER LEVEL RIDGE OVER THE MID-MISSISSIPPI VALLEY. THIS SHOULD GIVE US A CHANCE TO DRY OUT...BUT ITS A HOT PATTERN. GOING FORECAST HAS TEMPS CLIMBING BACK INTO THE 90S BY FRIDAY/SATURDAY. THIS ACTUALLY MAY NOT BE HOT ENOUGH...HOWEVER WOULD LIKE TO SEE ANOTHER COUPLE OF MODEL RUNS BEFORE CRANKING UP THE TEMPS.
