Area Forecast Discussion National Weather Service Topeka KS 346 AM CDT Sun Aug 25 2019 .SHORT TERM...(Today through Monday) Issued at 346 AM CDT Sun Aug 25 2019 MCS associated with a seasonally-strong shortwave continues to push east-southeast early this morning. Overall weakening trends have been noted with some cell mergers ahead of the primary line leading to some more intense updrafts. The persistent low cloud over the region has helped keep instability in check to the east of this system and expect a general decline in strength through the remainder of the morning and early afternoon. Earlier training storms has also subsided and heavy rainfall concerns continue to diminish as well. Plenty of cloud and rain-cooled air should again keep temperatures cool though some late day insolation is possible especially in western locations. The next upper wave dropping southeast into the northern Plains induces lee cyclogenesis to the northwest tonight with a moderate low- level jet developing over the cool boundary-layer air. There could be enough isentropic upglide for drizzle or light showers late tonight into Monday morning in northern and eastern areas. Models continue to show stout ML CIN resulting but also rather quick erosion of it in southeastern locations as a cold front approaches. The upper trough remains well north and the cap erosion remains in question with dewpoints rising through the day potentially keeping stratus in place, but isolated to scattered deep moist convection remains possible in the late afternoon and early evening before the front exits to the southeast. 500 mb winds remain progged to reach around 45 knots from the west for a moderate shear and strong CAPE combination and severe weather potential, with hail and wind the primary concerns. Highs Monday should return to the middle 80s in the south given some afternoon insolation with the elevated dewpoints pushing heat index values into the 90s. .LONG TERM...(Monday night through Saturday) Issued at 346 AM CDT Sun Aug 25 2019 A weak shortwave pushes southeast toward Kansas Tuesday into Tuesday night though this serves to reinforce the surface ridge with moisture depths rather weak to support any precipitation. A weak elevated WAA regime could develop Wednesday night behind the surface ridge mid-week for small precip chances. A stronger wave in the continued northwest flow brings greater potential in the Friday to Saturday periods. Temperatures Thursday could push back to near normal after a few more cooler days with cooler temps again late in the forecast. && .AVIATION...(For the 06Z TAFS through 06Z Sunday night) Issued at 1153 PM CDT Sat Aug 24 2019 MVFR ceilings this evening once again degrade to around IFR levels overnight, with showers and thunderstorms moving through from west to east between now and 15Z. MVFR ceilings persist for much of Sunday, lifting late Sunday afternoon. Winds should be from the east to south at 5 to 10 kts. && .TOP WATCHES/WARNINGS/ADVISORIES...
