We have time for a second forecast on this beautiful Saturday, and we will take it to Dalton, north of Atlanta. In our forecast for Hartford, we previewed an active Monday down in Georgia, so let’s see just how it plays out.
At 815PM, ET, Dalton was reporting a temperature of 61 degrees with clear skies. A sharp ridge of high pressure remains in place across the Eastern Seaboard and will ensure that the weekend will stay pleasant and dry. A sharp trough over the Plains will start moving to the east through the day, resulting in some clouds filtering into the region by late in the day on Sunday.
The trough is quite sharp, but is being drawn to the north by the mean flow. As a result, the base of the trough will extricate from the main trough, and become more independent late in the day tomorrow, and a surface low will attempt to organize by Monday morning. Expect heavy rain to arrive in the early morning, just in time to slow down rush hour, but the cut off low will begin working to reassociate with the mean flow and will move through quickly. Expect the evening rush on Monday to be back to normal.

It sounds as though it will be getting a bit nasty as the work week starts, but at least the weekend will end on a nice note. Here is satellite from the University of Illinois, with isobars to show you were that southern low is developing.
