Updated at 1128 PM CST TUE DEC 9 2025 - Medium chances for fog with visibilities below one mile in southeast portions of Central Alabama for a few hours this morning. Temperatures will be below freezing in some areas but probability of any impacts from freezing fog is very low at this time. - Seasonable temperatures expected this week with little chance for rain until the weekend. && .DISCUSSION... (Today through next Tuesday) Issued at 1128 PM CST TUE DEC 9 2025 A trough is expected to swing through Midwest today, pushing a cold front southward through Central AL later this evening into Thursday morning. Rain chances are very low with this frontal passage as moisture availability is limited. However, some of the higher resolution guidance has tried to introduce some light showers across the area, though I`ve left mention of rain out of the forecast for now due to low confidence in the scenario. Likely the most noticeable impact of the front will be the increased winds through the day. Drier northerly flow will be in place Thursday, shifting more southerly on Friday leading to a slight warming trend as we reach the end of the week. Our next system is expected to move through over the weekend with the frontal boundary to our south lifting northward as an effective warm front and stalling across Central AL. This could lead to low chances for rain Saturday night into Sunday, but the trend in the guidance has been drier for the last few runs, so any precip may be more scattered. The long-awaited cold surge has now been pushed back to Monday in the guidance, but given we haven`t seen a lot of consistency from run to run, I`d have little confidence in the forecast for early next week at this point in time. 25/Owen && .AVIATION... (06Z TAFS) Issued at 1128 PM CST TUE DEC 9 2025 VFR conditions expected for most locations through the period; however, high res guidance continues to highlight the eastern and southeastern portions of Central AL with the potential for fog development. HREF shows a 50% chance of dropping below 1 mile VIS for MGM and AUO, so will include that trend in the TAFs. Looking just over into Central GA, a few sites are already registering 1/4 mi VIS. Temperatures are expected to be near freezing with the fog development in our area, so we`ll be monitoring for freezing fog development if it becomes dense enough. Conditions improve after roughly 12-15z with increasing winds expected through the day. 25/Owen && .FIRE WEATHER... MinRHs will generally remain above 50% today with the frontal passage expected in the evening through overnight. Increased westerly winds will be in place for much of the day, shift northerly behind the front. Min RHs Thursday will drop into the mid to upper 30% range. Our next chance for any rainfall appears to be Saturday evening through Sunday morning, but will likely remain scattered at best with the next frontal passage. && .PRELIMINARY POINT TEMPS/POPS...
