983 FXUS63 KICT 231739 AFDICT Area Forecast Discussion National Weather Service Wichita KS 1239 PM CDT Thu May 23 2024 .KEY MESSAGES... - A few severe storms possible today through tonight. - A higher-end severe weather setup is possible for Saturday afternoon-night - Dry Monday and Tuesday. - Potential for increasing thunderstorm chances mid-late next week. && .DISCUSSION... Issued at 311 AM CDT Thu May 23 2024 TODAY--THIS EVENING...Increasing warm advection and moisture transport amidst gradually increasing large scale ascent from the west could support a few hit-or-miss thunderstorms today (as early as mid-morning). If a few storms can manage to develop, initial activity would be "elevated" rooted above the boundary layer, with the strongest activity posing a risk of isolated large hail given the instability/shear combination. As the afternoon progresses, these elevated storm chances should become more surface-based with daytime heating. Additional isolated surface-based storms could develop in the vicinity of a dryline late this afternoon and evening over western Kansas, possibly reaching locations along/west of I-135 during the evening. All of these afternoon-evening isolated storm chances could pose a risk for large hail, damaging winds, and a few tornadoes. The tornado threat will be focused during the evening, coincident with an increasing low-level jet. All-in-all...weak upper forcing should keep any activity through this evening fairly isolated, so not everyone will see a storm. LATER THIS EVENING--EARLY FRIDAY...A linear complex or two of thunderstorms is expected to sweep east-southeast across Nebraska and Iowa, as a strong cold intersects the dryline and surges in from the northwest. While the greatest chances should remain mostly north of the forecast area given stronger capping over the southern half of Kansas, the strong linear forcing should support at least scattered modest chances across central, south-central, and southeast Kansas. The more linear storm mode will support isolated pockets of damaging winds, with again more widespread chances over northern Kansas and Nebraska. All activity will exit southeast Kansas to the east by mid-morning Friday. SATURDAY AFTERNOON-NIGHT...The potential for a more synoptically evident severe weather episode could take shape somewhere across the Central and especially Southern Plains, as approaching shortwave energy sharpens a dryline across the High Plains, amidst increasing moisture/instability. Anomalous 500-250mb flow per the NAEFS supports long cyclonically looping hodographs, supportive of supercells capable of all severe weather hazards. However, there remains some decent forecast uncertainty, especially surrounding quality moisture return. Early Saturday will feature a cool, dry, and stable post-frontal airmass. Strengthening deep southerly flow should return rich/quality moisture rapidly northward through the day. Consequently, because of this "just in time" moisture return, low clouds may tend to encompass a good part of Kansas through the day, limiting heating and associated surface-based destabilization. This scenario would keep the greatest threat for higher-end severe weather further south across Oklahoma. Stay tuned as we continue to refine forecast details. LATE SUNDAY--EARLY MONDAY...A fleet-footed potent shortwave and associated cold front could spell additional shower/thunderstorm chances late weekend into early Monday. This is especially portrayed by the GFS, with little to no support by the ECMWF and Canadian. For now will continue 20-30 PoPs until model agreement increases. MONDAY--TUESDAY...Dry northwest flow should support dry and pleasant weather early next week, with lower dewpoints and seasonable temperatures. WEDNESDAY--FRIDAY...Deterministic and ensemble consensus turns the mid-upper flow more zonal by mid next week, supporting increasing moisture/instability and associated thunderstorm chances. Stay tuned as forecast details continue to be refined over the coming days. && .AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...

Issued at 1234 PM CDT Thu May 23 2024 Low clouds near MVFR category will spread from western Kansas into central/south central Kansas this afternoon. Southeast winds will be on the increase for this afternoon as surface low pressure deepens over eastern Colorado today. Isolated storms will be possible along the dry line which could move into parts of central/south central Kansas by this evening. Otherwise the better chances for a line of showers and storms will wait until the cold front moves southward into Kansas. The front looks to push into southeast Kansas by late Friday morning.
