CRAMERWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Springfield, MO wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 17, 6:05 PM CDT, 2 minutes earlier.
Area forecast discussion, Aug 17, 6:05 PM CDT, 2 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 605 PM CDT FRI AUG 17 2007 .SYNOPSIS... THE REMNANTS OF A DIFFUSE SURFACE FRONT STRETCHED FROM NORTHEAST KANSAS AND ACROSS THE MISSOURI OZARKS FRIDAY AFTERNOON. MODEST SURFACE CONVERGENCE ALONG THIS BOUNDARY WAS RESULTING IN SURFACE MOISTURE CONVERGENCE AND AN AXIS OF HIGHER LOW LEVEL THETA-E. SURFACE BASED CAPES WITHIN THIS MOIST AXIS WERE SURPASSING 3000 J/KG. THIS INSTABILITY WAS EVIDENCED BY THE DEVELOPMENT OF CUMULUS AND ISOLATED CONVECTION ON THE OZARK PLATEAU OF SOUTHERN MISSOURI. A WEAK UPPER LEVEL SHEAR AXIS WAS ALSO IN PLACE ACROSS THE REGION BETWEEN THE WESTERLIES TO THE NORTH AND THE CIRCULATION AROUND THE REMNANTS OF ERIN TO THE SOUTHWEST. FOSTER && .DISCUSSION... SEASONABLY HOT AND HUMID CONDITIONS ALONG WITH INCREASING CHANCES OF CONVECTION ARE EXPECTED THIS UPCOMING WEEKEND. THE REMNANTS OF ERIN AND THE WEAK FRONT WILL PLAY A ROLE IN ENHANCING RAIN CHANCES. MODELS DIFFER ON THE EVOLUTION OF THE LEFTOVER CIRCULATION FROM ERIN...BUT WILL FOLLOW CLOSER TO THE GFS SOLUTION WHICH HAS BEEN MORE CONSISTENT AND HAS BETTER CONSENSUS AMONG OTHER MODELS. THE GFS SHEARS OFF SOME SHORT WAVE ENERGY WHILE MAINTAINING THE PRIMARY CIRCULATION OVER WEST TEXAS. THIS ENERGY WILL EJECT NORTHEAST THEN EAST ACROSS THE REGION THIS WEEKEND. THE ASSOCIATED MOISTURE PLUME WILL PUSH PRECIPITABLE WATER VALUES TO NEAR 2 INCHES. EXPECT SCATTERED TO NUMEROUS CONVECTION TO DEVELOP SATURDAY AFTERNOON WITH THE FOCUS OF ACTIVITY FROM SOUTHEAST KANSAS INTO CENTRAL MISSOURI. CONVECTION WILL BE MORE CONCENTRATED FROM THE OZARK PLATEAU NORTHEASTWARD INTO CENTRAL MISSOURI ON SUNDAY. LOCALLY HEAVY RAINFALL WILL BE POSSIBLE BUT DRY ANTECEDENT CONDITIONS WILL PRECLUDE ANY SIGNIFICANT FLOODING RISK. THE INCREASE IN CLOUDS AND SHOWERS WILL KEEP HIGH TEMPERATURES CLOSER TO NORMAL ALTHOUGH IT WILL BE MORE HUMID. THE SUBTROPICAL RIDGE WILL REASSERT ITSELF NEXT WEEK WITH THE CENTER OF THE HIGH ANCHORING OVER THE SOUTHEAST U.S. TEMPERATURES WILL LIKELY BE ABOVE NORMAL IN THE MIDDLE AND UPPER 90S. HIGHS MAY NOT REACH 100 AS THE HIGHER 500 MB HEIGHTS WILL BE TO THE SOUTHEAST AND THE ATMOSPHERE MAY BE MORE MOIST. ISOLATED DIURNAL CONVECTION CANNOT BE RULE OUT ANY DAY BUT COVERAGE WILL BE VERY LIMITED. SOME QUESTION ABOUT THE IMPACT OF A SUBTROPICAL LOW THAT WILL RIDE THE PERIPHERY OF THE RIDGE. THE GFS BRINGS THIS FEATURE INTO THE CENTRAL U.S THE MIDDLE OF NEXT WEEK BUT DEPICTS LITTLE PRECIPITATION. RAIN CHANCES WILL HAVE TO BE INCREASED IF THIS SYSTEM MATERIALIZES. FOSTER && .AVIATION... ISOLATED THUNDERSTORMS MAY AFFECT THE SPRINGFIELD AND JOPLIN TERMINAL VICINITIES THIS EVENING. OTHERWISE VFR CONDITIONS WILL PREVAIL. LIGHT HAZE WILL ONCE AGAIN DEVELOP TOWARD SUNRISE WITH AREAS OF MVFR VISIBILITIES. AN INCREASE IN CONVERGE OF SHOWERS AND THUNDERSTORMS IS EXPECTED SATURDAY AS MOISTURE INCREASES.
