Area Forecast Discussion National Weather Service Wichita KS 1145 PM CDT Fri Aug 24 2018 ...Updated for Aviation Discussion... .UPDATE... Issued at 849 PM CDT Fri Aug 24 2018 Latest observational and short-term model trends suggest a slight chance for a few showers/thunderstorms overnight and into Saturday morning across south-central and southeast Kansas, within a zone of above normal precipitable waters and 850-700mb warm advection, on the southern fringe of a Midwest upper jet streak. Not expecting strong/severe storms. Adjusted PoPs through late morning Saturday to account for this change. Kleinsasser && .SHORT TERM...(This evening through Monday) Issued at 247 PM CDT Fri Aug 24 2018 Main challenge is chances for elevated convection tonight into Saturday morning. At early afternoon, a weakening surface trof was situated across central Kansas. Meanwhile, a band of elevated showers continued to linger across northern Oklahoma into the southeast corner of Kansas. This zone of instability and moisture transport in the 850-700mb layer will shift gradually north tonight into Saturday morning across south central into east central Kansas. A modest low level jet should aid lift and may result in isolated to widely scattered convection tonight, so have inserted a low PoP/isolated mention for this possibility. Otherwise, the main theme through the weekend and into Monday will be increasing diurnal south winds and a return to unseasonably warm weather. Winds may approach advisory levels on Monday afternoon which is something we have not seen in some time. Convective chances will remain small, though non-zero, with some elevated moisture transport and weak lift on the southern edge of transient shortwaves aloft. This should result in slight to modest nocturnal/early morning chances over parts of central Kansas through the weekend. Darmofal .LONG TERM...(Monday night through Friday) Issued at 247 PM CDT Fri Aug 24 2018 A more pronounced upper trof will sweep east across the northern Plains/Upper Midwest Monday night/Tuesday which will push a modest strength cold front across the area. The upper ridge will build east from the southern Rockies across the Texas panhandle by mid- week with weak west-northwest flow aloft over Kansas and some low level moisture returning north across the area. This may give rise to slight to modest precip chances though confidence is not high at the moment on daily trends. KED && .AVIATION...(For the 06Z TAFS through 06Z Saturday night) Issued at 1142 PM CDT Fri Aug 24 2018 Quiet VFR conditions expected for most locations overnight through Saturday evening. However, will likely see a few isolated to widely scattered showers/thunderstorms overnight through Saturday morning across south-central and southeast Kansas, within a zone of warm advection and deep/rich moisture transport underneath the right entrance region of a Midwest upper jet.
