821 FXUS63 KTOP 011931 AFDTOP Area Forecast Discussion National Weather Service Topeka KS 231 PM CDT Mon Jun 1 2026 .KEY MESSAGES... - Low chance for a few strong to severe storms overnight tonight across north-central Kansas. Gusty winds and small hail are the main hazards. - Additional chances (20-45%) for rain come Tuesday evening/night into Wednesday, mainly across central Kansas. - Higher chances (30-50%) for more widespread rain come Thursday into the weekend. - Temperatures remain near or slightly above normal, with highs in the 80s and lows in the 60s. && .DISCUSSION... Issued at 231 PM CDT Mon Jun 1 2026 Mid-level ridging holds strong over the Central and Southern Plains this afternoon with an embedded gravity wave sparking showers and isolated storms across the forecast area. Continual propagation to the east-southeast has been noted through the day and there doesn`t appear to be anything that would prevent this activity from continuing for at least the next couple of hours. Additional thunderstorms that develop across eastern Colorado and western Kansas this evening will ride the ridge east and then southeast across central Kansas. This complex is expected to weaken with eastern extent as the cold pool pushes ahead of the leading edge. CAMs show the strongest portion of the complex staying south of the forecast area. Even so, the environment across northeast Kansas will feature weak shear and 1000-2000 J/kg of MUCAPE by midnight, gradually decreasing through the early morning hours. Thus, a few strong wind gusts up to 60 MPH and small hail are possible, but the severe risk should be confined to central and north central Kansas. Showers and storms linger into Tuesday morning before dry conditions return by the afternoon. There is a conditional risk for a couple of storms to develop during the afternoon/evening Tuesday, but this will be dependent upon mesoscale features (such as remaining outflow boundaries) given a lack of focused large-scale ascent. The majority of CAMs keep the forecast area dry, with the HRRR and RRFS being the exception. If storms do develop, they could produce gusty winds and small hail. Another complex of showers and storms will develop across western Kansas Tuesday evening and advance northeast towards the forecast area into Wednesday morning. Intensity of this round of storms should be weaker than the one tonight as instability will drop of with eastern extent. Dry conditions return again Wednesday afternoon before yet another area of showers and storms develops across the High Plains and moves towards the area Wednesday night. A shortwave works to flatten the ridge by Thursday and its passage brings the next chance (30-50%) for showers and storms Thursday into Friday. A closed upper low slowly lifts northeast across the Plains this weekend, but guidance varies in speed of this wave and the most likely timeframe for associated showers/storms. The signal for severe weather isn`t overly strong at this point; CIPS and CSU severe probabilities show a low chance (10% or less) for severe weather Friday-Sunday.&& .AVIATION /18Z TAFS THROUGH 18Z TUESDAY/... Issued at 1223 PM CDT Mon Jun 1 2026 VFR conditions expected. Current showers west of KMHK should dissipate before reaching the site. There could be some shallow fog overnight, mainly at KTOP, but think elevated winds just off the surface and increasing clouds will limit fog development. Showers and storms may approach KMHK after sunrise Tuesday, but confidence in eastern extent of precipitation is too low to include in TAF. && .TOP WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...Flanagan AVIATION...Flanagan
