Area Forecast Discussion National Weather Service Springfield MO 322 PM CDT Fri Jun 8 2018 .SHORT TERM...(This evening through Saturday) Issued at 320 PM CDT Fri Jun 8 2018 An upper level ridge remains over the Plains this afternoon. An above normal air mass is also in place across the area as temperatures are currently in the upper 80s to lower 90s with heat index values in the middle to upper 90s this afternoon. Isolated thunderstorms will be possible this afternoon into this evening. A strong storm or two may be possible with winds in excess of 45mph, but widespread severe weather is not expected. An upper level disturbance will track south across northern and eastern Missouri tonight into Saturday. The better chances for storms will be north and east of the area, but some storms may clip the northern and eastern portions of the forecast area tonight into Saturday morning. Highs on Saturday will once again top out in the upper 80s to the lower 90s, with heat index values in the middle 90s to around 100. Drier air will start to work into the area in the mid levels on Saturday. An isolated storm or two will be possible but the drier air will limit coverage and most locations should remain dry after any morning convection pushes out of the area. .LONG TERM...(Saturday Night through Friday) Issued at 320 PM CDT Fri Jun 8 2018 The upper level ridge will nudge east across the region by Sunday and again allow temperatures to warm into the lower 90s. Heat index values in the upper 90s to around 100 degrees will again occur. Drier air in the mid level will remain in place across the area on Sunday. This will help to limit thunderstorm develop potential. An isolated thunderstorm or two will still be possible though given the increase in instability with the heating of the day Sunday afternoon. An upper level trough will track east into the Plains early next week. This will flatten the ridge and allow slightly cooler temperatures next week, with highs generally warming into the middle 80s each afternoon. A front will also move through the area and could generate some thunderstorms. The area will remain in a more zonal type flow pattern next week and some periodic storm chances will be possible at times next week. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 100 PM CDT Fri Jun 8 2018 South to southwesterly winds will prevail across the area this afternoon through tonight. Winds may be gusty at times this afternoon. Diurnal cumulus clouds will occur this afternoon into early this evening. Isolated thunderstorms will also be possible this afternoon into this evening, but coverage will be limited and did not have confidence to include any mention of thunder in the Tafs. && .SGF WATCHES/WARNINGS/ADVISORIES...
