058 FXUS63 KTOP 012018 AFDTOP Area Forecast Discussion National Weather Service Topeka KS 218 PM CST Thu Jan 1 2026 .KEY MESSAGES... - Cooler air in place through tomorrow then a warming trend into next week. - Could see another foggy morning Friday with early morning clouds similar to Thursday morning. - Variability and spread in solutions remain high for potential precipitation Thursday/Friday next week. && .DISCUSSION... Issued at 217 PM CST Thu Jan 1 2026 An amplified slowly evolving pattern remains in place across the CONUS with a deep Hudson Bay low spinning over the Hudson Bay region with a trough axis extending through the New England region into the Atlantic. Northwest flow is the primary feature in place through the Great Lakes into the northern Plains with a broad amplified ridge building over the western states. A southern Pacific low pressure system is de-amplifying as it translates east into the Four Corners region with some spillover of mid to high clouds across the Rockies. Across the local area, the previous shallow and weak cold front that moved through the area has stalled generally over southern Kansas with low level moisture slow to mix out this afternoon. Remaining low level stratus continues to erode to the northeast this afternoon but most will see sunshine for the balance of the afternoon. Later this evening into the overnight, the stratus is progged to build back into the area with a reinforcing shot of cooler air as high pressure expands from the northern Plains southeast into the region. This could help reinforce low level saturation into tomorrow morning with with fog possible again across portions of the area similar to this morning and low level stratus once again. Unsure how dense the fog may become but if dense fog develops once again, then thinking favored areas are from north-central into east-central Kansas. Most impacts are travel related and aviation related but should once again improve by midday into early afternoon on Friday. Friday evening into the overnight period, weak and shallow frontogenesis may allow for light wintry precipitation to develop through eastern Nebraska and could slip into portions of northeast Kansas but right now overall lift in the lowest layers appears weak and overall saturation depth appears limited to support much in the way of precipitation entering northeast Kansas. Probability is too low to increase POPs across these areas at this time as the focus area could even move into Iowa and weaken as the overall northwest flow shifts east with the further amplification of the western ridge. This sets the stage for a warmup late Saturday into Sunday and into next week which is trending well above normal for the first full week of January. Expect a repeat of Christmas week temperatures. Currently, spreads look fairly narrow in the NBM data sets which would suggest a higher level of confidence pointing toward highs in the upper 50s and even higher into the 60s especially Monday and Tuesday while lows settle in the 30s most of next week. && .AVIATION /18Z TAFS THROUGH 18Z FRIDAY/... Issued at 1144 AM CST Thu Jan 1 2026 IFR cigs beginning to thin and eventually scatter out over the next couple of hours into the afternoon. Expect a few hours of SCT low cigs this afternoon before beginning to fill back in this evening with a very similar setup leading to possible morning fog again tomorrow morning. The best areas for dense fog appear to be generally west and southwest of the terminals again with only about a 20-30% chance for dense fog across the terminals for now. Have gone with mention of low cigs for now and will watch for trends regarding fog formation in later forecast updates. && .TOP WATCHES/WARNINGS/ADVISORIES...
