592 FXUS63 KICT 122348 AFDICT Area Forecast Discussion National Weather Service Wichita KS 648 PM CDT Mon Aug 12 2024 ...Updated Aviation Discussion... .KEY MESSAGES... - Chances for showers and storms tonight, with highest certainty of coverage lying north of US-50. - Warm to near-dangerous heat Tuesday and Wednesday, especially along the Kansas-Oklahoma border. - Showers and storms possible Thursday morning and again Friday/Saturday nights, but coverage uncertain at this time. && .DISCUSSION... Issued at 225 PM CDT Mon Aug 12 2024 Water vapor imagery indicates an upper ridge setting up over the High Plains as a deep trough is situated just off the California coast. Surface analysis reveals a stationary front draped from west to east across Kansas as a surface low sits over the Texas/Oklahoma Panhandles. PRECIPITATION... An upper-level perturbation is expected to make its way across the Central Plains later tonight into early Tuesday morning, bringing with it chances for scattered showers and storms. The latest CAM guidance suggests coverage mainly along and north of US Hwy 50 beginning after midnight in central KS and pushing eastward, with a handful of showers potentially building southward toward the Kansas-Oklahoma border. Respectable elevated instability and deep shear (~1500 J/kg and 35-45 kts respectively) may allow for some stronger storms to produce up to nickel-sized hail and brief gusty winds up to 50 mph, but not looking for widespread severe weather with this latest system. Medium-range deterministic models agree on a deeper upper-level disturbance reaching the Central Plains late Wednesday into early Thursday. This will bring with it a cold front that is expected to pass through Kansas Thursday morning and bring additional chances for showers and storms to central and south-central portions of the state. As with the latest system, this activity is not expected to be severe, but nonetheless should bring some much-needed precipitation to the region. Additionally, slight chances for showers will return Friday and Saturday night, but most of the area should stay dry through the weekend. TEMPERATURES... A wide range of high temperatures will be possible across the forecast area tomorrow depending on the extent and duration of precipitation. Central and south-central Kansas should see highs near and above normal, while areas along and east of the Flint Hills may struggle to make it into the low 80s in the afternoon. The upper-level ridge is expected to strengthen tomorrow into Wednesday, bringing near- to above-average temperatures midweek to central and south-central Kansas. With dewpoints near and above 70, heat indices approaching 105 degrees will be possible especially along the Kansas-Oklahoma border. Due to uncertainty regarding the southward extent of precipitation and subsequent cloud cover, will hold off on issuing heat headlines for now and defer to tonight`s shift. Otherwise, look for normal summertime high temperatures to prevail through the weekend. && .AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/... Issued at 639 PM CDT Mon Aug 12 2024 VFR ceilings will prevail this evening with light winds mainly out of the east. A complex of thunderstorms is expected to move through central Kansas early tomorrow morning bringing thunderstorms and lower ceilings to RSL, GBD, SLN, and HUT prior to sunrise. Confidence on thunderstorm coverage farther south remains more uncertain but there is at least a 30% chance that ICT will see thunderstorms Tuesday morning. With these thunderstorms, ceilings are expected to drop into the MVFR range and could drop into the IFR range for short periods of time during the heaviest rainfall. These lower ceilings will dissipate by mid to late Tuesday morning with VFR and dry conditions expected for Tuesday afternoon. && .ICT WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...JWK AVIATION...WI
