.DISCUSSION...
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.
