AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ST LOUIS MO 645 PM CDT SUN AUG 6 2006 .DISCUSSION... GOOD TO BE BACK. THANKS FOR THE PRAYERS...THOUGHTS...CARDS. THINGS ARE GOING WELL. A COLD FRONT NOW FROM NORTH CNTRL IOWA INTO NORTHWEST MISSOURI NEAR ST. JOSEPH TO A SURFACE LOW NEAR TOPEKA AND THEN WEST ALONG INTERSTATE 70. THE FRONT APPEARS TO BE CONTINUING SLOWLY TO THE SOUTHEAST. TEMPERATURES CONTINUE TO SOAR AHEAD OF THE FRONT WITH 100 DEGREES OR MORE FROM COLUMBIA WEST AND SOUTHWEST THROUGH MISSOURI. DEWPOINTS HAVE MIXED OUT AGAIN SO HEAT INDICES REMAIN BELOW ADVISORY THRESHHOLDS. MID AFTERNOON CAPES ARE OVER 3000 IN THE NORTHEAST QUARTER OF MISSOURI AND UP TO 4500 NEAR THE SURFACE LOW NORTH OF KANSAS CITY. THE REMNANTS OF THE SHORT WAVE OVER LAKE MICHIGAN HAVE SWEPT EAST WITH THE SOUTH END OF CLOUDS NEAR SPRINGFIELD IL. MEANWHILE THUNDERSTORMS HAVE BEEN DEVELOPING FROM LAKE OF THE OZARKS SOUTHWEST INTO WESTERN ARKANSAS. THESE STORMS HAVE BEEN MOVING VERY SLOWLY TO THE SOUTH AND SHOULD NOT AFFECT OUR FORECAST AREA. A NEW LINE OF THUNDERSTORMS IS EXPLODING JUST NORTH OF THE FRONTAL SYSTEM OVER FAR NORTHERN KANSAS. THESE SHOULD MOVE EAST AND MAY DRIFT INTO FAR NORTHEAST MISSOURI AND SOUTHERN IOWA LATER TONIGHT. OTHERWISE WE EXPECT QUIET CONDITIONS TO PERSIST FOR TONIGHT ACROSS EASTERN MISSOURI AND SOUTHWEST ILLINOIS. HIGH PRESSURE OVER SOUTHERN CANADA SHOULD DRIFT SOUTHEAST INTO WISCONSIN BY TOMORROW EVENING. THIS SHOULD ALLOW THE FRONTAL SYSTEM COMBINED WITH OUTFLOWS FROM TONIGHTS ACTIVITY TO FOCUS PRECIPITATION FURTHER SOUTH MONDAY INTO MORE OF OUR AREA. WE LOOK FOR REDEVELOPMENT MONDAY AFTERNOON IN NORTHEAST MISSOURI WITH AN EAST-SOUTHEAST DRIFT OF ACTIVITY INTO EAST CENTRAL MISSOURI AND SOUTHERN ILLINOIS MONDAY NIGHT. CLOUDS MAY HOLD TEMPS DOWN A COUPLE OF DEGREES TOMORROW BUT THE DEWPOINTS WILL PROBABLY BE HIGHER. WILL NOT ISSUE HIGHLIGHTS FOR HEAT ADVISORIES AT THIS TIME AS THEY WILL STILL REMAIN ON THE LOW SIDE OF MARGINAL TOMORROW WITH CLOUDS AND PRECIPITATION KEEPING THEM OUT OF THE DANGER ZONE ON TUESDAY. THE FRONT WILL WASH OUT BY EARLY TUESDAY. IN THE LONGER RANGE AN UNSEASONABLY DEEP TROUGH IS FORECAST TO REDEVELOP OVER THE NORTHEASTERN U.S. WITH A HIGHLY AMPLIFIED RIDGE OVER THE ROCKIES. THE BISTATE AREA REMAINS IN A LIMBO AREA BETWEEN THEM. OVERALL MODELS INDICATE SOME COOLING AND ALSO POINT TO A PRETTY DECENT CHANCE FOR A PERIOD OR TWO OF MUCH NEEDED PRECIPITATION. PEDIGO && .AVIATION... FOR THE 00Z TAFS... COLD FRONT ACROSS EASTERN IOWA TO NW MO WILL DROP SLOWLY INTO NORTHERN SECTIONS OF THE FORECAST AREA AFTER MIDNIGHT...REACHING THE KSTL AREA AROUND MIDDAY MONDAY. WIDELY SCATTERED TSTMS NEAR KUIN AND KCOU THIS EVENING. OTHERWISE...FEEL THE BEST CHANCE OF TSTMS WILL HOLD OFF TIL MIDDAY MONDAY IN THE KCOU-KSTL REGIONS. SCATTERED TSTMS ALONG AND AHEAD OF THE FRONT WILL MOVE INTO KUIN AFTER 06Z. VFR CONDITIONS SHOULD PREVAIL THROUGH TONIGHT AND MONDAY MORNING EXCEPT MVFR IN THE TSTM AREAS.

A COLD FRONT WILL PUSH INTO THE AREA THIS EVENING AND ACT AS A FOCUS FOR THUNDERSTORM DEVELOPMENT IN A VERY MOIST AND UNSTABLE ATMOSPHERE. THE PRIMARY THREATS WILL BE LARGE HAIL AND DAMAGING WINDS. ELSEWHERE...THERE IS A CHANCE FOR THUNDERSTORMS FOR AREAS NORTH OF INTERSTATE 70 LATER TONIGHT. STORMS THAT FORM IN THESE AREAS ARE NOT EXPECTED TO REACH SEVERE LIMITS.
