Area forecast discussion, Jul 7, 11:33 PM CDT, 2 hours 12 minutes before
Area Forecast Discussion National Weather Service Springfield MO 1133 PM CDT Fri Jul 7 2017 .SHORT TERM...(tonight through Saturday) Issued at 245 PM CDT Fri Jul 7 2017 Weak frontal boundary will move southward through southern Missouri into this evening. Front will not be strong enough to induce widespread upward motion but expect to see at least isolated convection as boundary layer further warms. Questions arise in whether the convection will be strictly diurnal in nature as model ensembles suggest convection will last into the night as H8 front moves slowly through. Given heat induced instability...some stronger storms will be possible including isolated damaging wind. Seasonably warm yet noticeably more mild temperatures are then expected on Saturday as a modified Canadian air mass moves through the region. .LONG TERM...(Sunday through Friday) Issued at 245 PM CDT Fri Jul 7 2017 Pops will be a tad higher on Sunday as high departs setting up modest return flow...otherwise expect only isolated diurnal thunderstorm chances through the coming week as the ridge flattens across the Central Plains. Temperatures will warm under this dome driving afternoon heat indices upward to around 100 daily. && .AVIATION...(For the 06Z TAFS through 06Z Saturday night) Issued at 1039 PM CDT Fri Jul 7 2017 Pilots can expect prevailing VFR conditions at area terminals tonight through Saturday as a front moves south of the area. Some patchy light fog or haze will be possible early Saturday morning. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. && SHORT TERM...Runnels LONG TERM...Runnels AVIATION...Foster
