AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 215 AM CDT FRI JUL 19 2002 FORECAST CONCERNS: PRECIPITATION CHANCES TODAY THROUGH SATURDAY AND THEIR IMPACT ON TEMPERATURES AS WAS THE CASE LAST NIGHT...CONVECTION FORMING DURING THE OVERNIGHT HOURS ACROSS THE FORECAST AREA...TIED TO THE LOW LEVEL JET. AREA OF SCATTERED SHOWERS OVER CENTRAL MISSOURI ASSOCIATED WITH MID LEVEL OUTFLOW FROM IOWA CONVECTION THURSDAY EVENING. SHOWERS AND THUNDERSTORMS HAD DEVELOPED ALONG THE MISSOURI/ARKANSAS BORDER SOUTH OF WEST PLAINS BETWEEN 0630 AND 0700 UTC. 850 MB WINDS ONLY ABOUT 20 KNOTS...BUT 925 MB WINDS ARE CLOSER TO 30 KNOTS ACROSS SOUTHEAST KANSAS AND EASTERN OKLAHOMA. UNSETTLED WEATHER WILL CONTINUE TODAY THROUGH SATURDAY...WITH LOW CONFIDENCE IN PRECIPITATION CHANCES. ALTHOUGH MID LEVEL SHEAR AXIS WILL MOVE SOUTHEAST OF THE FORECAST AREA TODAY...SURFACE BOUNDARIES WILL STILL BE PRESENT ACROSS THE OZARKS...WHICH WILL LIKELY RESULT IN SCATTERED DIURNAL CONVECTION.

ETA SUGGESTS THAT NORTHWEST ARKANSAS WILL BE THE PRIME LOCATION FOR NOCTURNAL CONVECTION TONIGHT...BUT WILL LEAVE IT IN AREA WIDE FOR NOW. LATER SHIFTS MAY BE ABLE TO TRIM THE POPS IN NORTHERN SECTIONS. SATURDAY IS ANOTHER QUESTION MARK. HAVE NOT MADE ANY CHANGES TO POPS...BUT COULD SEE THEM BEING DROPPED TO THE SLIGHT CHANCE CATEGORY IF MODELS VERIFY: WITH MID LEVEL HEIGHTS RISING...ONLY FOCUSING MECHANISM FOR STORM DEVELOPMENT WILL BE SURFACE BOUNDARIES. AVN AND CANADIAN CONSISTENT IN BRINGING SURFACE FRONT INTO THE FORECAST AREA MONDAY AFTERNOON. HAVE ADDED A CHANCE POP TO THE NORTHWESTERN THIRD OF THE FORECAST AREA MONDAY AFTERNOON AND EVENING.
