Issued at 326 AM EST Fri Nov 14 2025 - Warm advection underway IR loop shows a band of mid clouds stretching from northern Lower to the Ohio Valley moving east. These clouds are the tell tale sign of warm advection overhead. There are clearing skies behind it and we`ll see plenty of sunshine and warmer temperatures today. Highs will be in the mid 50s today. - Chance of light rain Saturday, then cooler The next cold front will move across the region Saturday. The stronger dynamics with the system are over northern Lower and eastern Lower. It`s possible we could see a brief shower (25 to 30 Percent) but not everyone will. Those that do may see 0.01 or so, but most areas will remain dry. The cold front will, however, put and end to highs in the 60s that we see Saturday. By Sunday, highs will be back in the 40s. - Showers late week A larger souther stream system looks like it will affect the Great Lakes late next week. Rain will be back in the forecast by Wednesday night as moisture streams north ahead of it from the Gulf. && .AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
