NWS St. Louis, MO wrote its last area forecast discussion before the first event at Jun 25, 9:58 PM CST, 1 hour 52 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED AVIATION NATIONAL WEATHER SERVICE ST LOUIS MO 1058 PM CDT WED JUN 25 2008 .DISCUSSION... /236 PM CDT WED JUN 25 2008/ QUITE A BUSY DAY AROUND HERE...AS LAST NIGHTS EXCESSIVE RAINFALL SENT FORECAST CRESTS ON THE MISSISSIPPI RIVER HIGHER AND LATER. MESOSCALE OUTFLOW BOUNDARY FROM THIS MORNINGS MCS HAS STALLED FROM NORTHWEST MISSOURI THROUGH THE ST. LOUIS METROPOLITAN AREA EAST TO NEAR EFFINGHAM...ILLINOIS. EXPECT AT LEAST ISOLATED CONVECTION ALONG THIS BOUNDARY LATE THIS AFTERNOON AND EVENING GIVEN INSTABILITY AND LACK OF CAP. BUT WIDESPREAD...ORGANIZED CONVECTION IS UNLIKELY DUE TO THE LACK OF FORCING THROUGH THIS EVENING. ANOTHER MCS WILL LIKELY DEVELOP TONIGHT FROM NEBRASKA INTO SOUTHERN IOWA AND NORTHERN MISSOURI. MAYBE JUST A TAD FURTHER NORTH THAN LAST NIGHT (AT LEAST I HOPE). SHORT WAVE ENERGY MOVING ACROSS NEBRASKA AND KANSAS WILL PROVIDE SYNOPTIC LIFT FOR INITIATION AND A SOUTHWEST LOW LEVEL JET WILL PROVIDE PLENTY OF MOISTURE TO SUSTAIN A HEAVY RAIN EVENT ACROSS THIS AREA. THE NAM SOLUTION SEEMS MOST REASONABLE...AND FOLLOWED IT CLOSELY. HAVE INCREASED POPS ACROSS NORTHERN MISSOURI COUNTIES AND ADDED HEAVY RAINFALL WORDING. WILL LET THE EVENING SHIFT WATCH CONVECTIVE DEVELOPMENT TO THE WEST...AND PLACE FLASH FLOOD WATCHES WERE THEY ARE NEEDED. TONIGHTS MCS SHOULD FOLLOW SAME SUIT AS TODAY...DIMINISHING DURING THE MORNING...BUT LEAVING AN OUTFLOW FOR AFTERNOON CONVECTION ACROSS THE AREA. THEREFORE...HAVE ADDED SOME CHANCE POPS IN FOR THURSDAY. MAIN ZONE OF CONVECTION SHOULD FOCUS FURTHER NORTH THURSDAY NIGHT AND FRIDAY...BUT STILL OVER THE MISSISSIPPI RIVER BASIN. SPC HAS MOST OF THE AREA HIGHLIGHTED FOR SEVERE WEATHER ON THE DAY3 OUTLOOK AS A STRONG SHORTWAVE WILL DROP SOUTH FROM CANADA INTO THE GREAT LAKES...DRAGGING A SLOW MOVING COLD FRONT THROUGH THE AREA FRIDAY NIGHT AND SATURDAY. IT APPEARS MOST OF THE CWA WILL HAVE TO WAIT UNTIL FRIDAY EVENING OR OVERNIGHT FOR THIS NEXT BOUT WITH THUNDERSTORMS...BUT GIVEN UNCERTAINTY KEPT POPS NEARLY IDENTICAL TO PREVIOUS FORECAST. THE FRONT CLEARS THE AREA ON SATURDAY WITH POPS DECREASING FROM NORTH TO SOUTH. EXTENDED FORECAST... ECWMF AND GFS ARE VERY SIMILAR WITH 500MB FLOW THROUGH TUESDAY. DEEP 500MB LOW WILL PINWHEEL ACROSS THE GREAT LAKES WITH SPOKES OF VORTICITY KEEPING AT LEAST SLIGHT CHANCES OF SHOWERS SUNDAY AND MONDAY ACROSS AT LEAST THE EASTERN HALF OF THE CWA. THIS SHOULD BE MOSTLY A DIURNAL CHANCE OF PRECIPITATION. TEMPERATURES WILL BE COOLER...ESPECIALLY ACROSS ILLINOIS WITH LOW TO MID 80S COMMON. BRIEF HIGH PRESSURE AT THE SURFACE BUILDS ACROSS THE REGION MONDAY NIGHT/TUESDAY...BUT ECWMF SUGGESTS WARM ADVECTION AND CHANCES OF PRECIPITATION MAY RETURN AS EARLY AS TUESDAY NIGHT/WEDNESDAY AS A TRAIN OF SOUTHWEST SHORTWAVES BEGIN TO AFFECT THE MIDWEST. IF THIS PATTERN SETS UP...ADDITIONAL HEAVY RAINFALL FROM MCS DEVELOPMENT WOULD OCCUR WEDNESDAY...THURSDAY...AND FRIDAY ACROSS THE MISSISSIPPI VALLEY NEXT WEEK. THIS WOULD CERTAINLY NOT BE GOOD NEWS FOR THE MISSISSIPPI RIVER.
