322 FXUS63 KICT 072009 AFDICT Area Forecast Discussion National Weather Service Wichita KS 309 PM CDT Tue May 7 2024 .KEY MESSAGES... - Few strong/severe storms possible Wednesday morning across far southeast KS. - Dry conditions expected through the rest of the work week with some small rain chances returning for the end of the weekend. && .DISCUSSION... Issued at 309 PM CDT Tue May 7 2024 Water vapor imagery currently shows an upper low rotating across the Northern Plains with one of the main vort lobes extending from the Northern Intermountain into the Central Rockies. At the surface, cold front extends from northern MO into far eastern OK. A few sprinkles or light showers will be possible early this evening for areas generally along and north of I-70 in an area of 700mb warm advection. However, low levels are so dry that it`s going to be tough for much to reach the ground. Vort lobe to our west is expected to translate east tonight and by Wed morning stretch from southeast Nebraska into CO and at the same time, low level moisture will surge north across eastern OK into southeast KS. There is decent model agreement in some storms developing after 09z across southeast KS in an area of 850mb moisture transport. Any storm that develop should quickly move off into MO by the late morning hours. Even above 850mb, there looks to be plenty of instability for large hail, even with marginal shear. Cold front should push back to the southeast by the early afternoon hours with the more substantial surface convection expected southeast of the forecast area. There is good agreement between the GFS and ECMWF in the upper low over the Northern Plains shearing out with some of the upper energy getting cutoff across the Great Basin by Thu and remaining there through at least Fri. Meanwhile to our east, northwest flow aloft will be in place with this setup providing dry conditions and comfortable temps. Cutoff low to our west will start to move east on Sat, tracking over the Central Rockies Sat night. Ahead of this feature, some scattered showers and storms will be possible on Sun across mainly western KS into Western OK with some of this affecting the western portion of our forecast area. At this time, not looking for any severe weather with this activity. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1233 PM CDT Tue May 7 2024 VFR conditions expected to prevail thru the forecast valid period. Occasionally gusty southwest winds will develop this afternoon across central Kansas. Moisture advection will occur across southeast Kansas late tonight ahead of a weak cold front. The main impact to central Kansas will be a wind shift with a period of high clouds. For southeast Kansas and the KCNU terminal, mid-level bases/cigs are expected toward 12z with widely scattered elevated convection possible during the morning hours on Wednesday. A period of low level wind shear is also expected across south central Kansas tonight in vicinity of the frontal passage and across southeast Kansas early Wednesday morning.
