048 FXUS63 KDDC 282251 AFDDDC Area Forecast Discussion National Weather Service Dodge City KS 551 PM CDT Sat Jun 28 2025 .KEY MESSAGES... - Highs on Sunday will be in the mid to upper 90s with afternoon heat index of 100 to 102 possible east of highway 183. - Marginal risk for severe thunderstorms late Sunday and Sunday night as a cold front crosses southwest Kansas. Main hazards will be strong gusty winds and locally heavy rainfall. - Cooler temperatures will start off the work week but a warming trend will return to southwest Kansas mid to late week. && .DISCUSSION... Issued at 202 PM CDT Sat Jun 28 2025 Earlier morning an upper level trough was located over Idaho, with a westerly flow observed ahead of it across the Northern and Central Rockies. East of the Rockies, a surface low pressure trough was present and across the Northern Plains, a cold front was situated over the Dakotas and Northern Wyoming. Isolated thunderstorms possible tonight across west central and south central Kansas. Thunderstorm development will be monitored this evening along the surface trough of low pressure that will extend from northeast Kansas into east central Colorado. Any storms that manage to develop are expected to move eastward and weaken during the early evening hours. There is a low probability (20% or less) that isolated, weakening storms may cross the Colorado border before fully dissipating between 6pm and 10pm. Another opportunity for low probability (15% or less) for a few elevated thunderstorms will occur between 3am and 9am Sunday morning across south central Kansas. In this area 850mb warm air advection/850mb-700mb moisture transport will develop east of the warmer mid level temperatures (700mb temperature gradient). Heat Index of 100 to 102 possible on Sunday east of highway 183. These westerly downslope flow conditions, combined with the warm 850mb and 700mb temperatures support the current NBM forecast with afternoon highs expected to climb into at least the mid 90s today. This warm air mass will persist across western Kansas on Sunday, making Sunday almost a carbon copy of today. Highs may end up being a few degrees warmer. In addition to these unseasonably warm temperatures, there is a greater than 70% chance for dew points to exceed 65 degrees east of the surface low pressure trough, which will move from Colorado into western Kansas during the afternoon. Based on the latest short term model consensus, it appears these higher dew points will primarily remain east of Highway 183, suggesting that afternoon heat index values around 100 can again be expected in that area. These unseasonably warm temperatures on Sunday will occur ahead of a cold front, which will move across southwest Kansas by late day/early Sunday night. Early this afternoon this cold front will progress under some warm mid level temperatures as it approaches southwest Kansas. As a result, even with afternoon heating and increasing mid level instability...what convection that tries to develop along this boundary may stay isolated to widely scattered until early evening. As the cold front moves into southwest Kansas Sunday evening the convection is expected to increase in coverage along this surface boundary. The main hazard from the stronger storms early Sunday night currently appears to be strong gusty winds across western Kansas given the low level lapse rates, high cloud based and forecast downdraft cape. Heavy rainfall will also require monitoring Sunday evening, as forecast Precipitable Water values east of Highway 283 are expected to be near the 90th percentile. Looking ahead to Next Week. Once the cold front passes Sunday night, the rain will end from northwest to southeast. The latest CAMs indicate 850mb temperature trends supporting afternoon temperatures around 10 degrees cooler on Monday compared to Sundays expected highs. Enjoy this break in the heat while you can because this cooler air early next week will gradually give way to a warming trend late week as an upper ridge moves eastward across the Rockies and into the Plains. && .AVIATION /00Z TAFS THROUGH 00Z MONDAY/... Issued at 548 PM CDT Sat Jun 28 2025 VFR flight category for all terminals during the time period. Isolated thunderstorms have developed mainly north of GCK and we could see isolated storms in the vicinity of GCK and LBL from 00-06Z however the probability of a thunderstorm affecting either terminal will be less than 30%. During the afternoon on Sunday a slow moving cold front will stall out along the I-70 corridor and will be the focus of storm development after 21Z that could lead to some VCTS near HYS between 21Z-00Z. Any thunderstorm either tonight or tomorrow could have downburst winds over 40 kts. && .DDC WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...Burgert AVIATION...Tatro
