Area forecast discussion, Aug 13, 2:15 AM CDT, 11 hours 32 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 215 AM CDT THU AUG 13 1998 PROBLEMS TODAY: NEED FOR DENSE FOG ADVISORY AND PRECIPITATION CHANCES ISOLATED SHOWERS AND THUNDERSTORMS AROUND SPRINGFIELD GAVE UP THE GHOST AROUND MIDNIGHT BUT PLENTY OF MIDDLE AND HIGH CLOUDS REMAINED ACROSS THE REGION. ISOLATED SHOWERS HAVE STARTED TO REDEVELOP OVER CENTRAL MISSOURI AND EASTERN KANSAS. SURFACE FRONT TRYING TO DISSIPATE OVER NORTHERN ARKANSAS WITH 70+ DEWPOINTS FROM SPRINGFIELD AND JOPLIN SOUTH. MODEL GUIDANCE SIMILAR: SHORT WAVE OVER THE CENTRAL PLAINS WILL MOVE SLOWLY SOUTH OVER THE NEXT 24 TO 36 HOURS AND CONTINUE THE CHANCE OF RAIN ACROSS THE OZARKS. WITH PRECIPITABLE WATER VALUES AROUND 1.5 INCHES AND STEERING WINDS LESS THAN 10 KNOTS...HEAVY RAINFALL WILL BE A DEFINITE POSSIBILITY WITH ANY STORMS THAT DEVELOP. A MENTION OF SUCH WOULD BE A GOOD IDEA IN THE ZONES. PROBLEM 1: PATCHY DENSE FOG DEVELOPED ALONG THE MISSOURI/ARKANSAS BORDER WEDNESDAY MORNING. BELIEVE THE SAME WILL OCCUR THIS MORNING BUT NOT CONFIDENT THAT THE COVERAGE WILL BE GREAT ENOUGH TO WARRANT A DENSE FOG ADVISORY. WOULD LIKE TO KEEP THE EARLY MORNING FOG CURRENTLY IN THE ZONES AND PUT OUT AN NPW IF THE NEED ARISES. PROBLEM 2: HATE TO JUST PUT OUT BLANKET POPS BUT DONT HAVE MUCH CHOICE WITH THE SHORTWAVE APPROACHING AND PLENTY OF MOISTURE AND INSTABILITY OVERHEAD. GREATEST CHANCES FOR RAIN APPEAR TO BE THIS EVENING INTO TONIGHT AS WAVE PASSES THROUGH. LOW CHANCE POP SHOULD BE KEPT FRIDAY SINCE AIRMASS WILL NOT CHANGE AND AVN IS HINTING THAT MORE WEAK SHORTWAVES WILL BE APPROACHING IN THE NORTHWEST FLOW. GUIDANCE TEMPERATURES LOOK REASONABLE. RECOMMENDATIONS:(FORECASTS PROVIDED FOR COORDINATION PURPOSES ONLY) SGF/UNO: MORNING FOG...OTHERWISE PARTLY CLOUDY WITH A 30% CHANCE OF SHOWERS AND THUNDERSTORMS. HIGH IN THE MIDDLE 80S. EAST WIND 5 TO 10 MPH. JLN: MORNING FOG...OTHERWISE PARTLY CLOUDY WITH A 30% CHANCE OF SHOWERS AND THUNDERSTORMS. HIGH IN THE MIDDLE AND UPPER 80S. EAST WIND 5 TO 10 MPH. AIZ/VIH: MORNING FOG...OTHERWISE PARTLY CLOUDY WITH A 30% CHANCE OF SHOWERS AND THUNDERSTORMS. HIGH 80 TO 85. EAST WIND 5 TO 10 MPH.
