.AVIATION /07Z SATURDAY THROUGH WEDNESDAY/... LIFR CIGs are being observed at all terminals at this time, and that will continue through this morning for all. Patchy dense fog is still possible, but likely closer to sunrise, and very brief. Either way, some VSBY reductions likely during that period, and CIGs will not improve until later. Gradual improvement is expected through the day, with conditions clearing out first at CHO, and last at MTN. CIGs will likely climb a few hours quicker than yesterday as winds turn out of the south and pick up to around 15 to 20 knots. Showers and thunderstorms will approach from the west this evening, but will likely be weakening as they do so. For now, left the mention out of any TAFs, but will continue to monitor as the day moves on. A cold front will move through on Sunday, leading to a return to VFR conditions and a shift to westerly winds. Prevailing VFR conditions across terminals on Monday and Tuesday, followed by periods of lowered CIGs and VSBYs associated with a strong cold front impacting the region between late Wednesday and Thursday. Southerly winds likely to shift northwesterly on Wednesday, with gusts up to 20 knots possible. AVIATION...CJL/KJP/SRT Update as of: 346 AM EST Sat Mar 7 2026
