Area forecast discussion, Aug 27, 1:50 AM CST, 12 hours 10 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 250 AM CDT WED AUG 27 2003 .DISCUSSION... ISOLATED CONVECTION CONTINUED INTO THE EARLY MORNING HOURS WEDNESDAY IN THE LAKE OF THE OZARKS REGION. THUNDERSTORM ACTIVITY WAS MORE CONCENTRATED FARTHER NORTH ALONG THE INTERSTATE 70 CORRIDOR IN CLOSER PROXIMITY TO WEAK SURFACE BOUNDARY THAT STRETCHED FROM EASTERN NEBRASKA AND ACROSS FAR NORTHERN MISSOURI. 8-BIT RADAR IMAGERY AT NWS SPRINGFIELD CLEARLY SHOWED AN OUTFLOW BOUNDARY AND GRAVITY WAVES THAT EMANATED FROM THE CONVECTIVE CLUSTERS THAT DEVELOPED TUESDAY EVENING. THIS BOUNDARY HAD PUSHED SOUTH INTERSTATE 44. SATELLITE IMAGERY AND PROFILERS SHOWED A SHEAR AXIS AND POSSIBLY AN EMBEDDED MESOSCALE VORTICITY CENTER OVER SOUTH CENTRAL KANSAS. SHORT TERM (TODAY THROUGH THURSDAY)... LITTLE CHANGE IN THE AIRMASS IS EXPECTED TODAY. FORECAST SOUNDINGS SUGGEST CAPES NEAR 3000 J/KG AND PRECIPITABLE WATER VALUES NEAR 1.75. THIS YIELDED ISOLATED TO SCATTERED CONVECTION TUESDAY AND WOULD EXPECT A SIMILAR SCENARIO TODAY. A COUPLE OF FEATURES MAY FOCUS ACTIVITY. FIRST THE DIFFUSE FRONT TO THE NORTH AND RESIDUAL MESOSCALE BOUNDARIES MAY ENHANCE CHANCES ACROSS CENTRAL MISSOURI INCLUDING THE LAKE OF THE OZARKS AND ROLLA AREAS. SECOND THE SHEAR AXIS OVER KANSAS MAY MIGRATE FAR ENOUGH EAST TO INCREASE CHANCES ACROSS SOUTHEAST KANSAS AND FAR SOUTHWEST MISSOURI. INCREASED AMOUNT OF CONVECTIVE DEBRIS ASSOCIATED WITH THUNDERSTORM ACTIVITY MAY KEEP HIGHS A DEGREE OR TWO COOLER. THE REMNANTS OF THE SHEAR AXIS WILL PUSH EAST INTO THE AREA THURSDAY. THIS ALONG WITH LITTLE MODIFICATION TO THE EXISTING AIRMASS WILL SUPPORT AT LEAST ISOLATED CONVECTION THURSDAY AFTERNOON AND EVENING. JOPLIN HAS REACHED 100 DEGREES THE PAST 10 CONSECUTIVE DAYS BUT COULD FALL JUST SHORT TODAY. THE HEAT WAVE WILL PERSIST INTO THURSDAY WITH POTENTIAL OF COMPRESSIONAL WARMING AHEAD OF AN APPROACHING FRONT. HEAT INDEX VALUES WILL AGAIN BE NEAR 105 FROM SOUTHEAST KANSAS INTO CENTRAL MISSOURI WHERE A HEAT ADVISORY WILL CONTINUE INTO THURSDAY. LONG TERM (FRIDAY THROUGH TUESDAY)... A TRANSITION IN THE PATTERN STILL LOOKS LIKELY INTO THE WEEKEND. THE STRONG SUBTROPICAL RIDGE WILL FLATTEN AND SHIFT SOUTHEAST IN RESPONSE TO WESTERLIES AND A SERIES OF SHORTWAVES BREAKING THROUGH ACROSS THE NORTHERN TIER OF THE U.S. THIS WILL ALLOW A FRONT TO SAG SOUTH INTO THE REGION LATE THURSDAY INTO FRIDAY. STILL SOME QUESTION JUST HOW MUCH PROGRESS THE FRONT WILL MAKE...BUT IT APPEARS IT WILL BE CLOSE ENOUGH TO ENHANCE RAIN CHANCES ACROSS WEST CENTRAL MISSOURI THURSDAY NIGHT. THE CLOSE PROXIMITY OF THE FRONT...AND POSSIBILITY OF A GOOD SUBTROPICAL FEED WILL INCREASE RAINFALL POTENTIAL FRIDAY. CLOUDS AND INCREASED SHOWER COVERAGE WILL BRING SOME RELIEF FROM THE HEAT. THE FRONT WILL SLOWLY DROP THROUGH THE AREA SATURDAY AS THE FLOW ALOFT BECOMES MORE SOUTHWESTERLY. THIS MAY RESULT IN COUPLE OF DAYS OF DECENT RAIN CHANCES AND THE POTENTIAL OF SIGNIFICANT RAINFALL AMOUNTS. I HAVE INCREASED RAIN CHANCES A LITTLE FRIDAY INTO SATURDAY. WITH THE FRONT PROGGED TO MAKE ONLY SLOW PROGRESS... I INTRODUCED RAIN CHANCES TO FAR SOUTHERN MISSOURI SUNDAY. THE PASSAGE OF THE FRONT AND ASSOCIATED CLOUDS AND PRECIPITATION SHOULD BRING AN END TO THE PROLONGED HOT SPELL. MORE SEASONABLE AND POSSIBLY BELOW NORMAL TEMPERATURES WILL CONTINUE EARLY NEXT WEEK. && .AVIATION... ISOLATED THUNDERSTORMS SHOULD REMAIN NORTH OF THE SPRINGFIELD AND JOPLIN AREAS THIS MORNING. HOWEVER SOME AREAS OF MVFR CONDITIONS IN LIGHT FOG MAY DEVELOP THIS MORNING AND PERSIST UNTIL 14Z (9 AM). VFR CONDITIONS WILL PREVAIL FROM MID MORNING INTO THIS EVENING. HOWEVER SCATTERED CUMULUS WILL FORM THIS AFTERNOON WITH BASES NEAR 5 THOUSAND FEET. ISOLATED TO SCATTERED THUNDERSTORMS WILL DEVELOP BY EARLY AFTERNOON AND CONTINUE INTO THE EVENING. && .SGF... MO...HEAT ADVISORY THROUGH THURSDAY NORTH & WEST OF THE OZARK PLATEAU. KS...HEAT ADVISORY THROUGH THURSDAY. FOSTER

THE HIGHEST HEAT INDICES WILL AFFECT AREAS NORTHWEST OF A LINE FROM COLUMBUS KANSAS TO GREENFIELD...BETWEEN 1 AND 6 PM. DISCUSSION: THE HOT TEMPERATURES WILL INTERACT WITH THE MOIST AND UNSTABLE AIRMASS TO PRODUCE ISOLATED TO SCATTERED THUNDERSTORMS. ATMOSPHERIC CONDITIONS WILL SUPPORT THE POTENTIAL OF DAMAGING DOWNBURST WINDS AND HAIL IN A FEW OF THE STORMS. THE HEAT WAVE WILL CONTINUE WITH HIGHS NEAR 100 DEGREES...AND HEAT INDEX VALUES OF 100 TO 105 DEGREES. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
