Broad upper ridging remains in place over the southwestern CONUS with a modest jet across the northern tier, leaving northeast Kansas under relatively weak flow aloft and subsidence. A modest cold front that moved through the area recently has ushered in a cooler and drier boundary layer, with clear skies and light winds observed. This pattern supports efficient radiational cooling at night and well-mixed, seasonable afternoons.

For the near term, the main forecast issues are temperatures and localized fog. The combination of clear skies, light winds, and relatively moist low levels in river valleys may support shallow ground fog toward daybreak, especially near the Kansas River basin and other local drainages. Any fog that develops is expected to remain patchy and shallow, with limited spatial extent and rapid dissipation after sunrise. Modest warm advection begins on the backside of the retreating surface ridge as low-level flow veers to a more southerly component this afternoon.

The midweek period features continued quiet conditions as another weak frontal boundary brushes the area from the north while upper- level flow backs slightly. Ahead of this front, low-level warm advection strengthens, and highs trend into the upper 70s to lower 80s across much of the area, with lows climbing into the upper 50s to lower 60s.The frontal passage will likely be dry across northeast Kansas, and large-scale ascent remains weak. As a result, precipitation chances are negligible, and sky cover stays generally low to moderate with a mix of sun and occasional thin cloud. Northerly to easterly winds behind the boundary are expected to remain modest, with speeds mostly under 15 mph. No meaningful impacts are anticipated from this frontal passage beyond modest day-to-day temperature variations.

Through the end of the forecast period, the synoptic pattern continues to favor ridging or weak zonal flow over the central Plains. Warm advection and subsidence support above-normal temperatures, with many locations likely seeing highs in the low 80s and mild nights in the lower to mid 60s. The airmass remains relatively dry, and the lack of substantial forcing or deep moisture suggests precipitation remains absent through at least Saturday.

VFR at all TAF sites through the TAF period. Some light, very shallow, transient fog around KTOP/KMHK should pose little to no impact early this morning. Otherwise, clear sky and light wind expected today.
