921 FXUS63 KOAX 061734 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 1134 AM CST Tue Jan 6 2026 .KEY MESSAGES... - Areas of dense fog ending from west to east this morning. - Unseasonably warm through Wednesday. - Measurable precipitation chances Thursday into early Saturday (40-60%). Some accumulating snow is possible. && .DISCUSSION... Issued at 544 AM CST Tue Jan 6 2026 Today and Wednesday: The dense fog has been much quicker to dissipate than earlier indicated and the remainder of the Dense Fog Advisory will likely be cancelled within the next hour. Mostly sunny skies today will allow for warmer temperatures than those on Monday with highs in the upper 40s to upper 50s. Abundant sunshine is forecast Wednesday with highs in the 50s to low 60s. The warm temperatures will combine with afternoon relative humidity of 25 to 35 percent to support high fire danger in much of eastern NE. Thursday through Saturday: The 00z models are in reasonably good agreement in progressing a shortwave trough (now off the CA coast) from the southern High Plains Thursday morning into the upper Midwest by that evening. Larger disparities exist in the track of the associated surface low with general model consensus keeping that feature to the south of our area. As such, highest PoPs Thursday (40-60%) are in southeast NE and southwest IA, decreasing with northward extent across the area. Daytime temperatures in the 40s will support all rain, which could transition to a rain-snow mix or all snow Thursday night if sufficient forcing for ascent can persist. On Friday, the models indicate another mid-level trough moving into the central U.S. with a deep, closed circulation eventually forming over the upper Midwest or Great Lakes by Saturday. A second round of precipitation is possible (30-40% PoPs) with that system Friday and Friday night with temperatures supportive of snow or a rain-snow mix. Latest EPS, GEFS, and NBM data indicate a 20-50% chance of an inch or more snow from Thursday night into Saturday morning with the highest probabilities in southeast NE and southwest IA. For now, it looks like there could be some minor travel impacts (slippery roads), but nothing significant. Keep an eye on the forecast for potential changes, especially if you have travel plans from Thursday night into Saturday morning. Sunday and Monday: A quick transition to zonal flow aloft Sunday will lead to warmer temperatures with highs mainly in the 40s. Continued warming is expected Monday with highs in the 40s and 50s. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1124 AM CST Tue Jan 6 2026 VFR conditions are in place this afternoon with winds out of the west-northwest at around 10 kts. Skies are mostly clear, with only a few high clouds wafting by across northeast Nebraska. Winds will decrease in speed overnight, and fall more southwesterly with increasing wind speeds starting at 17z of 20-25 kts that last into the afternoon. Areas of fog look to be less widespread tonight compared to this morning, with only areas of river/valley fog seeing the best chances -- largely north and east of Omaha into Iowa. && .OAX WATCHES/WARNINGS/ADVISORIES...
