DISCUSSION

Issued at 246 PM CST Wed Dec 3 2025

Mid-level, quasi-zonal flow resides across the Central Plains this afternoon with a positively-tilted shortwave over the Desert Southwest. The surface cold front has made its way through the entire area with breezy northwest winds ushering in a colder airmass. Low-cloud coverage has increased behind the boundary and modest ascent in a deeper cloud deck across east-central Kansas could generate some light precipitation this afternoon and evening. Initially, rain or drizzle is favored, but a cooling column could support a mix of snow later this evening before drier air works into the area. Cloud coverage will decrease from north to south through the evening, although there is uncertainty in how fast this occurs. Currently seeing clearing of low clouds closer to the Nebraska border, but high clouds are increasing from the southwest. It seems more likely than not to have at least a several hour period of clearing where good radiational cooling will drop temperatures in the teens and single digits. However, if clouds hang on longer, lows could be warmer than forecast and hold in the 20s. The record low temperature at Topeka could be in jeopardy; refer to the Climate Section below for details.

Surface high pressure controls the region tomorrow, leading to a chilly day with highs only reaching into the 20s. Surface winds become more southerly by Friday, aiding in bumping highs into the upper 30s to mid 40s, still below climatological norms. Northwest flow aloft persists into early next week with waves of energy passing through the mean flow. Guidance continues to highlight the Saturday night-Sunday wave as the most likely to produce some precipitation across the area. Ensembles are coming into better agreement with this wave and 30-50% of LREF members have measurable precipitation across the forecast area during this timeframe. NBM is slowly catching on, but its PoPs remain lower than the ensembles suggest. PoPs may increase with subsequent runs if this signal remains consistent. Thermodynamic profiles support a mix of rain and snow depending on timing and location of the wave, but precipitation amounts are favored to be minor at this time. Temperatures fall again on Sunday behind this system before moderating into the middle of next week.

SCT to BKN MVFR cigs have made their way overhead at terminals and are expected to hold through the daytime hours. VFR conditions return between 00-03z this evening, with uncertainty in exact timing of low cigs scattering out. North winds of 10-12kts with gusts around 20kts will continue through the afternoon before weakening this evening and becoming southerly near the end of the period.
