KEY MESSAGES
- Warmer today with highs in the low 40s east of the Missouri River, and mid to upper 40s west. A few spots along our far west could hit 50F.
- Warm temperatures continue Wednesday with breezy winds, followed by a brief cool down in the 30s for Thursday and Friday.
- Dry conditions continue for the extended forecast period.
LONG TERM
/THURSDAY THROUGH MONDAY/
The western CONUS H5 ridge will deamplify somewhat on Thursday as a strong shortwave off the coast of southwest California tracks northeast. A few waves are seen ejecting from the eastern periphery of the ridge near the Rockies. However, model guidance keeps these disturbances well away from the area. Sfc ridging moves over portions of the Northern Plains too, helping suppress any PoP chances for Thursday and Friday. Behind Wednesday's front, highs Thursday and Friday cool to the 30s.
This "cool down" will be short lived though as strong H8 warm air advection moves over a large portion of the Northern and Central Plains by the weekend and into early next week. Highs Saturday warm to the 40s for most locations, with widespread 50s across eastern Nebraska by Sunday. The warmth continues through at least Monday. Deterministic and ensemble guidance is also in fairly good agreement that dry weather prevails for the duration of the long term period.
AVIATION /06Z TAFS THROUGH 06Z THURSDAY/
Issued at 1138 PM CST Tue Dec 30 2025
Latest IR satellite and surface observations indicate the western edge of MVFR ceilings (FL020-025) over far eastern NE, including KOMA. Model data suggest those clouds will persist in the KOMA vicinity through 09-10z, though the irregular western edge of the cloud deck suggests that cloud coverage could oscillate between SCT and BKN after about 08z. Current indications are that KOFK will remain to the west of the low clouds moving south out of SD. Light northwest or west winds overnight become southwest Wednesday morning before switching back to northwest and then north late Wednesday afternoon into Wednesday evening.
