DISCUSSION

Issued at 158 PM CST Sun Nov 30 2025

Today through Monday...

A shallow, saturated, dendritic layer produced an abundance of flurries this morning, under a layer of stratus. By noon, only minor accumulations were reported. Temperatures remained cool atop the blanket of fresh snowcover today. By 2 PM, most locations were still in the teens and low 20s. Cold temperatures will persist overnight and into Monday, with morning bus stop temperatures in the low teens, but feeling more like the single digits above and below 0.

A mid level trough will move out of the Rockies and into the Central Plains Monday, bringing our next chance for precipitation. With a column of cold air well established, we thankfully won't have to deal with multiple precipitation types. Snow will begin to overspread the forecast area from west to east shortly after midnight tonight, and persist through morning, before diminishing through the afternoon. The latest model runs continue to lightly nudge the system south, focusing the heaviest precipitation across the southeast Nebraska/Kansas/Missouri border region. When all is said and done, amounts will range from around a trace to 1" north of I- 80, to 1"-3"+ along and south of I-80. With high snow-liquid ratios, the snow should be fairly light and fluffy. Luckily winds will be relatively weak tomorrow, at around 5 to 10 mph out of the southwest, limiting visibility reductions from blowing snow. With the potential for this system to impact travelers on the morning and evening commutes Monday, a Winter Weather Advisory has been hoisted for locations along and south of a line from Fairbury, to Nebraska City, to Clarinda, IA. This may need to be expanded a bit farther north if evening model runs trend up.

Tuesday and Beyond...

Dry weather returns Tuesday, under quiet northwesterly flow aloft. Temperatures are forecast to drop into the single digits Monday night/Tuesday morning, with apparent temps dipping just below 0. Temperatures warm slightly Tuesday afternoon, reaching the low to mid 30s, perhaps melting a bit of the current snowcover.

Our "warm up" will be short-lived, as a cold front swings through the central CONUS Tuesday night. Winds will swing around to the north Wednesday, as cold air barrels into the region. Temperatures may reach the 30s early, but fall through the afternoon. By Thursday morning, lows will fall into the single digits below 0. This combined with chilly north winds, will lead to wind chills in negative teens across northeast Nebraska and parts of western Iowa. A smattering of light precipitation may accompany the frontal passage, however the better moisture profiles will remain off to our northeast and southwest.

We will have another brief warm up Friday, before our next chance for wintry precipitation arrives next weekend.

AVIATION /06Z TAFS THROUGH 06Z TUESDAY/

Issued at 1114 PM CST Sun Nov 30 2025

Light snow is expected to overspread the area prior to 12z Monday, and linger into late morning at KOFK and early to mid afternoon at KOMA and KLNK. A period of higher snow rates and resultant lower visibilities is most likely at KOMA and KLNK --roughly in the 14-18z timeframe-- when IFR conditions are expected. Otherwise, MVFR conditions will prevail into Monday afternoon at the terminal locations. Light and variable winds at 06z will become light south before daybreak Monday.
