AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 211 PM CDT Fri Sep 5 2014 .SHORT TERM...(This Evening through Saturday) It was a hot and humid day over extreme southeast Kansas and the Missouri Ozarks. This led to strong instability within this airmass, with mixed layer capes exceeding 2500 j/kg in most areas. With a frontal system approaching from the northwest this afternoon and evening, we think strong to severe storms will be possible, despite the weak shear present. The primary hazard with the stronger storms this evening will be damaging wind gusts in excess of 60 mph. The highest concentration of storms should occur north of the Interstate 44 corridor, or essentially along and north of the frontal boundary. This frontal system will continue to push through southern Missouri tonight, leaving behind residual showers and thunderstorms. In fact, this activity could persist over southern Missouri into the Saturday morning hours. We think by noon Saturday, all locations will be dry across southern Missouri. The front will also chill temperatures down to comfortable levels. Highs on Saturday will only warm into the middle 70s. .LONG TERM...(Sunday through Friday) The upper level pattern through most of the Sunday through Friday time frame will be low amplitude and highly zonal. The summertime ridge becomes suppressed into southern Texas, allowing for westerlies to return over southern Missouri. This pattern shift will lead to additional thunderstorm chances next work week beginning Tuesday. Southerly winds commence Monday night bringing back a Gulf airmass by Tuesday. Models suggest that a short wave trough will approach and trigger a round of thunderstorms. Storm intensity could depend on the timing of these storms developing. This wave will also force a frontal boundary across the region, and is forecasted to stall out either over southern Missouri or northern Arkansas. This feature will become a focus for additional thunderstorm potential into Wednesday and Thursday. We could experience some decent rainfall amounts during the Tuesday through Thursday period. Have a great weekend and enjoy the cooler weather this weekend ! && .AVIATION...(For the 18Z TAFS through 18Z Saturday Afternoon) Issued at 1244 PM CDT FRI SEP 5 2014 A cold front will push southeast through the area from late this afternoon into this evening. Scattered thunderstorms are expected during this time period with showers and perhaps a few thunderstorms then lingering into late tonight and Saturday morning. MVFR and brief IFR can be expected beneath any storms. Weather models then continue to paint a signal for lowering ceilings for late tonight and Saturday morning. The highest probability for low-end MVFR and potential IFR will be at Springfield due to local terrain effects. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. && SHORT TERM...Cramer LONG TERM...Cramer AVIATION...Schaumann
