KEY MESSAGES

- Unseasonably warm through mid-week.

- Increasing precipitation chances Thursday night through Friday night. Some snow accumulation appears possible.

THURSDAY THROUGH SATURDAY

A closed-low ejects northeast from the Baja Peninsula area on Wednesday, bringing a threat of rain and snow to the south- central CONUS by mid-day Thursday. Significant discrepancies on timing and placement of the surface low remain between the three primary forecast systems (EC/GFS/GEM). The Euro is farther north, but the North American models have certainly acquiesced to a significant degree with today's 12Z runs.

Regardless, Thursday's chances for accumulating snow have grown over the past 48 hours. FWIW, the NBM suggests a 10-20% chance of more than 3" of snow for most of the CWA. This may be one of those systems where snow totals are dependent on temperatures with a rain/snow line bringing disparate impacts to neighboring counties. Cooler air will build in behind the deepening system as it departs.

AVIATION /00Z TAFS THROUGH 00Z TUESDAY/

Issued at 524 PM CST Sun Jan 4 2026

VFR conditions are observed at all terminals this evening. Winds will become light under 12 kts within the next hour, turning west southwest late this evening. Winds become south southeasterly for much of the daytime Monday but remain under 12 kts.

Fog development may occur primarily at KOMA and KLNK around 12z (30-45% chance) based on latest hires model guidance. However, some discrepancies are still noted with timing and location. Have introduced mentions of lower ceilings around this timeframe at those two respective terminals but kept in VFR. If confidence increases, expect to see potential BR and MVFR visibility mentions with the 06z issuance.
