DISCUSSION

Issued at 200 PM CST Sat Jan 24 2026

Tonight and Sunday:

A shortwave trough currently over the northern High Plains is forecast to pivot through the Mid-MO Valley Sunday along with a surface cold front. Ahead of that weather system, the northern fringe of a broad, winter-weather precipitation shield in place across the central and southern U.S. resides over far southeast NE and southwest IA with light snow ongoing in those areas. Latest CAM guidance suggests that area of light snow will remain quasi-stationary through about midnight before slowly drifting to our southeast. Snow rates are expected to remain low with additional snowfall accumulations of less than an inch. The Winter Weather Advisory remains in effect for Gage, Johnson, Nemaha, Pawnee, and Richardson Counties until midnight.

It will be another cold night with air temperatures of -5 to 0. Coldest wind chills in the negative teens are forecast in northeast NE.

On Sunday, there is a small model signal for isolated snow showers developing behind the cold front, mainly across SD and western NE. Forecast soundings indicate only a shallow layer of saturation at the top of the boundary layer in our area, so we will maintain a dry forecast at this time. Temperatures will be slightly warmer than previous days with highs in the teens.

A reinforcing shot of arctic air quickly moves through the area Sunday night with lows in the negative single digits and wind chills of -25 to -15. So, A Cold Weather Advisory will likely be required for part of the area into Monday morning.

Monday through Friday:

A series of low-amplitude disturbances are forecast to pass near or to the east of the region next week. Those upper-air features will be associated with surface fronts which are projected to move through the area on Monday night, on Tuesday night or Wednesday, and potentially Thursday night into Friday. The updated forecast during this time period will indicate sub-15% PoPs; however, the global, deterministic models depict some light-precipitation potential with the Tuesday night/ Wednesday and Thursday night/Friday systems. So, we'll be keeping an eye on that.

After a cold start Monday morning, downslope-enhanced warming will contribute to afternoon highs in the 20s to low 30s. Similar readings are expected for Tuesday and Wednesday with slightly cooler conditions (i.e., highs mainly in the 20s) on Thursday and Friday.

AVIATION /06Z TAFS THROUGH 06Z MONDAY/

Issued at 1107 PM CST Sat Jan 24 2026

VFR conditions favored through much of the period with departing mid-level clouds overnight. Still some hints at fog development at LNK and OMA, but vast majority of guidance keeps them clear (10% chance of fog). Some clouds around 2500-4500 ft AGL are expected to push in from the northwest Sunday afternoon, with potential for a few flurries, but guidance suggests they should gradually dissipate as they move through. Otherwise, expect light and somewhat variable winds overnight to settle in at northwesterly during the day. A few gusts of 18-22 kts will be possible as the clouds move in Sunday afternoon.
