Area Forecast Discussion National Weather Service Kansas City/Pleasant Hill MO 628 PM CDT TUE MAY 31 2016 .Discussion... Issued at 337 PM CDT TUE MAY 31 2016 Short range (Today through Thursday night): A slow moving cold front is located across northwest Missouri this afternoon. This front will be slowly forced southeastward across the area by an upper level trough that will be moving from ND into MN this evening tonight. Although the area remains uncapped this afternoon isolation from blow off from earlier convection over Kansas has limited instability. Consequently storms have been slow to initiate this afternoon. However, scattered convection will still be possible late this afternoon and evening as the cold front slowly progresses through the CWA. The cold front will push south and east of the area tonight with showers and thunderstorms pushing south and east of the area. Surface high pressure is then expected to build into the area tomorrow with the cold front stalling south of the area. A few showers can not be ruled out across the extreme southern CWA however dry area should uncut shower chances. High pressure will then remain in control over the area through Thursday night. Highs on Wednesday and Thursday will generally be in the upper 70s to near 80. Medium range: (Friday through Tuesday): High pressure finally shifts off to the northeast on Friday and warm air begins to advect back into the area pushing temperatures into the low to mid 80s. Friday night a upper level trough will move from the northern Plains into the Upper Midwest forcing a cold front into the CWA Friday night. Showers and thunderstorms will be accompany this frontal passage. Showers and thunderstorms will continue into early Saturday before conditions dry out. Highs on Saturday will be in the upper 70s to lower 80s behind the front. High pressure builds back into the region on Sunday. High pressure is then expected to keep conditions dry and comfortable through Tuesday. Highs Sunday will be in the mid-upper 70s and slowly warm into the upper 70s to the lower 80s by Tuesday && .Aviation...(For the 00Z TAFS through 00Z Wednesday Evening) Issued at 628 PM CDT TUE MAY 31 2016 Storms have developed along a weak cold front over northwest Missouri, though are struggling to build much further south.
